Design Elements of institutional framework for Spectrum trading

What is Spectrum Trading?
ITU study material on radio frequency management[[1]]explains spectrum trading as-
“In the traditional administrative approach to assignment and authorization system, spectrum is first allocated specified uses and then assigned to particular firms or public organisations that carry out the authorized use according to specific obligations as are laid down in a licence or permit. Secondary trading of spectrum, or simply ‘Spectrum Trading,’ permits the purchaser to change the use to which the spectrum was initially put while maintaining the right to use.”

Spectrum trading allows parties to transfer their spectrum rights and obligations to another party, in return for a financial or market benefit.  It allows the present user to decide when and to whom the spectrum authorization will be transferred and what sum it will receive in return.  The market, not the regulator, determines the value.  Further, a consultancy report commissioned by the European Commission, the consulting firm Analysys was cited whereby the following methods for transferring rights of use were identified -
• Sale – Ownership of the usage right is transferred to another party.
• Buy back – A usage right is sold to another party with an agreement that the seller will buy back the usage right at a fixed point in the future.
• Leasing – The usage right is transferred to another party for a defined period of time but ownership remains with the original rights holder
• Mortgage – The usage right is used as collateral for a loan, analogous to taking out a mortgage on an apartment  or a house.

Spectrum trading covers a range of possibilities, from straightforward change of ownership of an assignment with no change of use to more advanced variants in which assignments may be divided or amalgamated and use changed.[[2]]


Design Elements of institutional framework for Spectrum trading
The success of spectrum trading depends on appropriate institutional framework that precisely determines how rights of use of spectrum are transferred. In case spectrum trading is to be introduced in a country, the basic design elements that will need deliberation will be –
(a)  Definitionof property rights and liability rules in terms of [[3]] :
(i)           The band which is available for use;
(ii)          The geographical area in which it can be used;
(iii)        The period for which the licence is entitled;
(iv)         The uses to which it can be put;
(v)          The licensee’s degree of protection from other users;
(vi)         The licensee’s obligation not to interfere with other spectrum user’s rights.
(b)  Flexibilityor otherwise with Licensees to determine the services they want to provide with their spectrum, using the technology they deem to be the most efficient.
(c)  Transferabilityof property rights after trade - sale or lease, in whole or in part.
(d)  Terms and conditions of compulsory purchase backs (with compensation) if required by government under some extreme circumstances.
(e)  Need for defining or otherwise of the emission levels, interference limits
(f)   Arbitrationmechanisms in case of disputes.
(g)  Mechanismof putting in place a public register [[4]]to record changes in ownership and to ensure transparency for private users, effectively displaying information on opportunities and easing entry into unoccupied bands. [[5]]

[4] For example the Australian Communications Authority (ACA) maintains searchable register of licences to facilitate trading. - www.aca.gov.au
[5]The ability of regulators and licensees to keep track of current licences is an important component of market-based systems and can be facilitated by a publicly available database. Knowledge of the location of existing Tx’s and Rx’s (where feasible) will allow potential purchasers of rights to accurately model the existing interference environment they are seeking to enter and to enable them to properly assess the rights they seek to acquire. The database :
  • should enable regulators if called upon to adjudicate spectrum disputes and to enable them to track and assess the usage of spectrum in differing bands;
  • Should include additional tools to analyze, data on spectrum historical occupancy/usage and to interpret alternative propagation models.

Growing appetite for mobile data and suggested approach for India

Growing appetite for mobile data globally
Juniper has published it’s latest report on Mobile data traffic forecasts. As per them, the total mobile data traffic will exceed 90,000 Petabytes by 2017. What is more interesting is that 60% of this data will be offloaded to Wi-Fi networks and only 40% of the data generated by mobile devices will be carried through the cellular network by 2017. The report also emphasizes the roll that the small cells are going to play going forward.
Mobile data growth – Indian scenario

India today is on the verge of data revolution and in the current decade, data will transform the Indian telecom industry the way voice did in the previous decade. Indications are that data contribution from 2G will continue to rise, and 3G and LTE adaption will augment this growth. while the telecom industry in the rest of the world obtains 35-50% revenues from non-voice services, India derives only ~15% of sales from non-voice/ data services. Projections by UBS for major telecom players in India indicate that the non-voice revenues are going to be ~30% of total revenues for these players by 2020. These projections may well be surpassed if India is able to achieve a good broadband penetration backed by the recent policy pronouncement on National Broadband Plan.  As against the current broadband subscriber base of 14.68 million, the National Broadband Plan envisages provision of 160 million broadband connections (22 million DSL, 78 million cable and 60 million wireless broadband) by the year 2014. It is likely that the share of wireless broadband may be much more than the expectations as, like other countries, in India also; the data revolutions will piggy back on wireless broadband. 3G and Broadband Wireless Access (BWA) are expected to aid the growth of economy by boosting broadband growth.

Nokia Siemens Networks (NSN) M-Bit report indicates that mobile data usage in India has grown at 54% growth in 7 months and is likely to double every 12-14 months. This report can be accessed at http://www.nokiasiemensnetworks.com/sites/default/files/document/india_mobile_data_-_mbit_index.pdf . Evolution of data services in China provides some insight for the potential for the data segment growth for India. Data service revenue constitutes 30.6% of total service revenue in China as compared with 12.6% in India in FY11, giving an indication for strong data services growth trajectory in India in coming years. Credit Suisse estimates that over the next three years, data could more than double in size to a US$14 bn industry in India, contributing over half the incremental industry revenue and add 500 bp CAGR to an otherwise slowing voice industry. They estimate 3G’s contribution to mobile EBITDA to rise to 9-13% (from less than 5%) by FY3/14

Wi-Fi offload – a solution to handle growing data volumes and speeds

No doubt more and more carriers are adapting to Wi-Fi. Recently AT&T had inked a pact with Boingo - one of the leading Wi-Fi service provider having more than 600000 Wi-Fi Spots around the globe. Going forward the carrier-Wi-Fi adoption will be gather speed mainly because of two developments –

a)   NGH (Next Generation Hotspot) and Hotspot 2.0 specifications along with 5GHz enabled devices.

b)   Carrier-grade small cells along with Wi-Fi will enable high levels of capacity and along with the macro network will provide commercial and financial success to the operator.

Now what’s there for India in all this? Ironically, there are not many Wi-Fi hotspots in India currently. Given that almost one-sixth of the world's mobile subscribers are in India and that the country is already spectrum starved, in future offloading the mobile traffic on Wi-Fi is the only feasible and practical solution to cater to the growing hunger for data services.
ITU studies and other major research firms have already pointed out that the data requirements of future can never be met by increased availability of spectrum even if spectrum efficiency improve considerably. India cannot rely on vacation of frequencies by Defense ministry as the chances of this happening are remote. And even if this happens it will be a slow process. Thus demand and supply of spectrum in India will always have wider gaps than in other countries.

India specific approach – A Public Wi-Fi hotspot network

In such a scenario, it becomes important for the India to have a large number of Wi-Fi hotspots in almost all major cities and towns. There are two ways of doing this. The first way of approaching the problem is that the market is left to itself and the telecom operators or third parties like Boingo creates a Wi-Fi hotspot network. However the problem in this solutions can be  -

·         - The commercial criteria and not the country/public good at large will drive the hotspot creation
·         - All operators will target the same places for hotspot creation like Airports, bus and railway stations, big malls etc. They will end up creating duplicate infrastructure and in process may not get the return on investment. India missed the bus while the mobile towers were being erected and this resulted in sheer waste of resources by way of creating redundant infrastructure. All operators invested in mobile towers at same time and at same spots.

·         - Such approach slows down the rural penetration as all operators are busy spending their money in big cities. At least for Wi-Fi, we can eliminate this approach.


This leads us to the second and more practical approach of policy intervention to ensure that a common Wi-Fi network is created across major cities that can be shared on payment basis by all operators. This will help in savings on one hand and better ROIs on other. An added advantage can be faster rollout even in tier II and tier III cities. The Bharat Broadband Nigam Limited (BBNL) had been created by Government of India to roll out a common optical fiber network that can be shared across telecom service providers. On similar lines, BBNL can also be entrusted to create a common Wi-Fi network funded through USO. However, the entity will be able to make money once the Wi-Fi network is used by telecom operators. A Wi-Fi hotspot requires back-end connectivity, preferably on fiber so as to ensure that large numbers of users are supported by the hotspot at higher speeds. Suggested approach will ensure that BBNL will identify Point of Presence (POPs) for optical fiber as per the hotspot requirements. If implemented, such a solution can not only help in solving the spectrum crunch, but will also help Indian citizens to get higher broadband speeds at affordable prices – an objective that the NTP 2012 envisages to meet.

Internet Bandwidth consumed in making VoIP calls


This one is bit technical. As many of us have started making voice calls on the IP in our smartphones, I thought many of you would be interested to know how much internet bandwidth is consumed if you make a one minute of Voive call on IP i.e. VoIP call. Caveat - Some of highly technical stuff required cross-authentication from Geeks  (Learnt this from Wiki)

Here you go.....

Number of Bytes Consumed in VOIP

To know exactly how many bytes a voice conversation consumes, one needs to know which codec her VoIP service is using. 

CODECS 
A codec is a compression engine that transforms your (analog) voice into digital data, removing the silent moments (which make up to half of all conversations), and do other things to render the data load as light as possible. A codec is an algorithm (sort of a computer program), most of the time installed as a software on a server or embedded within a piece of hardware (IP Phones), that is used to convert voice (in the case of VoIP) signals into digital data to be transmitted over the Internet or any network during a VoIP call.
The word codec comes from the composed words coder-decoder or compressor-decompressor. Codecs normally achieve the following three tasks :
  • Encoding – decoding
  • Compression – decompression
  • Encryption - Decryption

Encoding - decoding

Codec digitizes your analog voice to digital. When you talk over normal landline phone, your voice is transported in an analog way. But with VoIP, your voice is converted into digital signals. This conversion is technically called encoding, and is achieved by a codec. At destination, digitized voice is to be decoded back to its original analog state so that the other person can hear and understand it.

Compression – decompression

Bandwidth is a scarce commodity. To make the digitized voice less bulky, it is compressed. By compression, the same data is stored but using lesser space (digital bits). Once it reaches its destination, it is decompressed back to it original state before being decoded. 
Encryption – decryption
Encryption is one of the best tools for achieving security. It is the process of changing data into such a state that it no one can understand. This way, even if the encrypted data is intercepted by unauthorized people, the data still remains confidential. Once the encrypted data reaches destination, it is decrypted back to its original form. Often, when data is compressed, it already is encrypted to a certain extent, since it is altered from its original state.

Common VoIP Codecs

CodecBandwidth/kbpsComments
G.71164Delivers precise speech transmission. low processor requirements. Needs at least 128 kbps for two-way.
G.72248/56/64Adapts to varying compressions 
G.723.15.3/6.3High compression with high quality audio.  Lot of processor power.
G.72616/24/32/40An improved version of G.721 and G.723 (different from G.723.1)
G.7298Excellent bandwidth utilization. Error tolerant. License required.
GSM13High compression ratio. Free and available in many hardware and software platforms. 
iLBC15Robust to packet loss. Free
Speex2.15 / 44Minimizes bandwidth usage by using variable bit rate.
The approximate values for data consumption of the most common codecs used for VoIP are as follows:
Codec      BR                     NEB
G.711      64 Kbps      87.2 Kbps
G.729      8 Kbps        31.2 Kbps
G.723.1   6.4 Kbps      21.9 Kbps
G.723.1   5.3 Kbps      20.8 Kbps
G.726      32 Kbps      55.2 Kbps
G.726      24 Kbps      47.2 Kbps
G.728      16 Kbps      31.5 Kbps
iLBC         15 Kbps      27.7 Kbps

BR = Bit rate
NEB = Nominal Ethernet Bandwidth (one direction)

Note  - The G.729 codec is one of the best performing voice codecs and most good VoIP services use it.


Calculation of Bandwidth required
Example - for one minute of talk with the G.729 codec.

Now G.729 uses 8kpbs of sampling. Normally one packet of 20 Bytes is sent. With a sampling rate of 8kpbs this means that in one sec, 50 packets are to be sent.
If we are using frame relay protocol over ethernet, the overheads to be used are as follows - 
Frame relay - 6 Bytes(incl header and trailer)
RTP - 40 bytes (breakup 20 bytes of IP, RTP-12 & UDP - 8) [Note if cRTP is used these 40 Bytes can be converted into 4 Bytes]
Ethernet - 18 bytes
Therefore, for each packet of 20 bytes in this case 64 Bytes of protocol and other header bytes are added. Therefore total 84 Bytes will be send. Overall 50 such packets are semt per sec, therefore bit rate is 50*84*8= 33.6 kbps (Mentioned as ~32 kpbs)
This translates into 1920 kilobits (60 x 32) in one minute, which in turn is 240 kilobytes (KB) per minute (1 byte is 8 bits). Now that’s only for the data going out. Inbound data (which also counts) takes the same load, so one can double the figure to 480 KB. This gives a round value to 0.5 MB per minute of conversation.

However, there are many parameters, that are rather technical in nature, affecting the values above. Among them are the compression technology, the size (payload) of the voice packets, the intervals at which they are sent, packet overhead, network protocol used and whether silence suppression is used. (Pl refer table below). If silence suppression/voice activity detection is used, the bandwidth consumption may drop 50%

Compressed RTP (cRTP) assumes 4-octets RTP/UDP/IP overhead per packet
Ethernet overhead adds 18-octets per packet
PPP/Frame Relay overhead adds 6-octets per packet
If we take the value of 50 kbps for any codec, it will give (after calculations and approximations) 0.75 MB per minute of conversation.

Fight for the scarce resource - "THE SPECTRUM"

Entry of Foriegn players in offering 3G mobile services
As per reports in economic times - A committee of Department of Telecom is said to have given its clearance on entry of foreign players in offering 3G mobile services and allocation of spectrum through auction. The group is said to have so far finalised two things -- that 3G is not an extension of 2G, implying that there is price to be paid through auction for spectrum to start 3G services, and entry of foreign players. Other issues including allocation of spectrum to public sector undertakings and pricing criteria are also being worked out.

At a time when voice revenues are falling, high-end value added services through 3G hold big potential for telcos to arrest the top line fall. The report indicated that the final policy is not likely to come out before July as lots of nitty-gritties have to be worked out along the broad framework of 3G, including allocation, auction methodology, benchmark price, number of players, PSUs (BSNL and MTNL) entitlements as per their existing rights. The sources said being PSUs, BSNL and MTNL will be given preference as unless supported they would not be able to compete and offer 3G services on their own. The PSUs will have pay some price for the spectrum to remain in the allocation benchmark, they said. Entry of foreign players will bring in competition and quality which would bring down the cost and make 3G services popular.

Meanwhile Tata Teleservices is opposing entry of foreign players in offering 3G services. Tata Teleservices feels this would lead to scarcity of spectrum and hamper the growth of existing operators and has demanded a level-playing field vis-a-vis foreign players.

Mandatory network sharing for roaming
Meanwhile, The Department of Telecom (DoT) plans to make it mandatory for all operators to open their networks to roaming customers from other service providers after the introduction of third generation (3G) telecom services in India. If implemented, private cellular operators will be largest beneficiaries as they will be roam on the extensive networks of state-owned BSNL. This proposal will also enable 3G subscribers to roam on the existing 2G networks. The move has been recommended by the internal committee of DoT, which is studying telecom regulator’s Trai recommendations on the allotment and pricing of 3G spectrum. The logic behind the DoT proposal is that “besides existing GSM and CDMA players, non-telecom companies and even non-Indian companies” will bid for 3G spectrum, when it is made available. As the constraint of 3G spectrum will limit the number of players in this sector, and since it will also not be possible for these players to roll-out these services on a pan-India basis, their customers will therefore have to depend on the 2G networks of existing operators when on roaming, the DoT committee has said. “In view of the limited number of service providers being recommended for 3G services and the fact that the extensive, country wide roll-out of 3G networks will take a reasonably long time, the 3G customers will have to depend on 2G networks and services in areas where 3G services are not available, or on 3G networks of other operators, wherever available for such time. Hence roaming amongst all service providers would be required and is therefore recommended to be mandated,” the DoT’s committee report said. Currently, all private operators share their network infrastructure and allow their customers to roam on the networks of competing service providers. The DoT committee recommendation gives private operators reasons to cheer as BSNL is the only telecom operator in India which does not share its infrastructure. In fact, many private operators have also demanded that the incumbent be mandated to share its nation-wide network created largely with public funds, on reasonable and non-discriminatory terms, adding that the terms of such sharing be regulated by Trai. The regulator has also been advocating the move. The Department of Telecom committee has also endorsed most of Trai’s recommendations on the allotment of 3G spectrum. While approving of Trai’s proposal that 3G spectrum be made available in the 2.l Ghz and 800 Mhz (for CDMA), it has however said that the availability of the 450 Mhz would be difficult. With just over 40 Mhz of 3G spectrum slated to be vacated by the defence forces, the committee has recommended that the allocation of the resource be limited to just four players, through a bidding process. Additionally, it has also recommended that ‘for security reasons, one slot of 3G spectrum be reserved for BSNL and MTNL’ during its allocation, where the PSUs will have to pay the price quoted by the second highest bidder during the auction process.

Limiting the number of operators to ensure spectrum availability
At this point of time the Indian telecom space is hit by the unavailability of spectrum. The Department of Telecom is said to be now considering to limit the number of operators in each service area to maintain a minimum quality of service. The step was necessary as "spectrum is a scarce resource and to ensure that the adequate quantity of spectrum is available to the licensees to enable them to expand their services and maintain the minimum quality of service." There are 23 telecom circles in the country. Currently, there is no cap on the number of service providers in a service area. As on date, 159 licenses have been issued for providing access services in the country and generally there are 5-8 providers in each service area. Since any Indian company can apply for unified access license, this is increasing the demand for spectrum in a substantial manner. In an evolving sector like telecom to ensure that the policies keep pace with the changes, DoT is seeking TRAI's recommendations on the issue of limiting the number of Access Providers in each service area. The Department is considering to review the whole set of crucial guidelines in the terms and conditions of access providers (cellular/unified access/basic) licenses. The terms and conditions slated to be reviewed are "substantial equity holding by a company/legal person in more than one license company in the same service areas, transfer of license and merger and acquisition guidelines." Besides, other guidelines like permitting service providers to offer access services using combination of technologies (CDMA/GSM and or any other) under the same license, roll-out obligations and requirement to publish printed telephone directory will also be reviewed. TRAI's decision could also decide the fate of Reliance Communications which is aspiring to enter the GSM space in a pan India presence and has thus applied for spectrum. As per DoT norms, no single company can have more than 10 per cent stake in two different cellular operators in the same circle. The guidelines also deal with market dominance and stipulate that the total market share of the combined entity cannot exceed 67 per cent in any circle.

Rajya Sabha MP and former owner of BPL Mobile, Rajeev Chandrasekhar, has joined the ongoing battle between the government and telecom operators regarding the allotment and pricing of 3G spectrum. In a communication to Prime Minister Manmohan Singh, Mr Chandrasekhar said that that the Department of Telecommunications’ (DoT) plans to allow foreign and non-telecom players to bid for 3G spectrum through an auction process must not be held hostage by Indian telecom companies. Mr Chandrasekhar’s communication comes as Tata Teleservices and GSM operators have expressed concern over DoT plans to allow foreign players to bid for 3G spectrum and said that “the existing 2G players must have the have the first right to use 3G spectrum as and when it is made available for allotment”. Mr Chandrasekhar is not a disinterested party. He is planning to bid for 3G spectrum in some metros, and will be prevented from doing so if the government bans non-telecom Indian players from participating in the auction. He has also pointed out that there were no restrictions on fourth round of cellular licenses and the recent FM licenses, while adding that restricting bidders would depress the real value of spectrum. Tata Teleservices, in its communication to DoT had alleged that the Centre was ‘disregarding the recommendations of Trai for facilitating the progress of existing GSM and CDMA operators from 2G to 3G services’. “At a minimum, we would expect that the issue of entry of new players, especially from overseas markets to be discussed openly. The interests of existing telecom licence holders who have done so much to make India the fastest telecom market in the world must be protected and a level-playing field provided to them,” the company had said.

Amid the ongoing debate over the entry of foreign players in 3G mobile services and opposition to this idea by domestic players, officials of Tata Teleservices, Bharti Airtel and Cellular Operators Association of India on Thursday met Telecom Secretary D S Mathur.
Sunil Mittal, CMD, Bharti group told the media, "My only point is existing players should get enough spectrum. We all know there is scarcity of 2G (voice spectrum)."
Former telecom minister Dayannidhi Maran had said foreign players should be considered to offer 3G services to bring in quality and comeptition. However, domestic players have opposed this proposal.

Who has got the right on spectrum - GSM v/s CDMA operators
In the fight for the spectrum, Cellular Operators Association of India has said CDMA players should be granted GSM spectrum only after the needs of the cellular service providers (GSM) have been fully met and secured.
Leading CDMA player Reliance Communications has applied for GSM spectrum to expand its mobile services in the country.
Both policy and regulation emphasize adequate availability of spectrum for existing service providers before considering the needs of new players, the COAI said in an approach paper on allocation 2G spectrum (voice).
It further said as the government is in the process of vacating spectrum in the 1800 MHz band to meet the additional spectrum requirements of GSM licensees, it is important to arrive at an equitable approach on how this additional spectrum be allotted among various service providers.
The requirements of CDMA service providers are met through spectrum in the 800 MHz band and when they migrated to UASL from fixed/WLL(M) licenses, it was on the understanding that they would provide the service in their already allotted spectrum and no additional spectrum will be given.
All the GSM licensees who are in commercial operations will come into the category of existing licensees and their spectrum requirements must be safeguarded up to at least 2x15 MHz before any subsequent licensee is considered, it said.

With the government expected to soon take a decision on the allotment of 2G spectrum for Reliance Communication’s GSM foray, existing GSM players have approached the Department of Telecom (DoT) demanding that allocation of this resource be prioritised. GSM players have said that despite the licence being technology neutral, they should have the first right to 2G spectrum as and when it is available. Besides, a GSM player who wants to expand operations to pan-India level should be given priority over new entrant Reliance Communications, they said. Last year, RCOM, which currently offers GSM services in eight circles, had applied for GSM spectrum on a pan-India basis. The company is also learnt to have floated a mega GSM tender estimated at over $6 billion. Recently, announcing the results for the year ended March 2007, chairman Anil Ambani had said that RCOM would roll out GSM services across the country within a year of spectrum being allotted. Opposing the move, the Cellular Operators Association of India (COAI), the body representing all GSM technology-based operators, had told DoT that telecom regulator Trai, during its earlier recommendations, had said that ‘additional spectrum, if available, should be given to existing operators for cost effective service. Quoting Trai, COAI said a fair balance between the two objectives of increasing competition on one hand and improving quality, coverage and price-efficiency of service on the other, has to be maintained so that the larger objective of providing quality services at affordable prices is not jeopardised. COAI also added that if new entrants were allocated GSM spectrum, at the expense of existing operators, then this will lead to ‘a sub-optimal cost structure and quality of service, which in turn will be detrimental to the growth of teledensity’. According to the GSM body, currently, the paucity of adequate spectrum for existing licensees have resulted in serious ‘quality of service’ issues, which have been highlighted by the regulator from time to time. Trai in its study papers have repeatedly said that spectrum shortage faced by operators was affecting the service quality. “Given that both policy and regulations emphasise on adequate availability of spectrum for existing service providers before considering the needs of new players, it is submitted that in the event that any CDMA licensee seeks an allotment of GSM spectrum, he will be able to get the same only after the needs of the GSM providers have been fully met and secured,” COAI said.

RCOM, Tata Teleservices and other CDMA operators have approached telecom tribunal TDSAT, seeking refund from the government of the excess fee charged during 2003-06 due to late implementation of the revenue sharing regime in allocation of spectrum. Accepting a petition by RCOM and CDMA body Association of Unified Telecom Service Providers of India, TDSAT chairman Justice Arun Kumar issued notices to the DoT and directed it to file a reply within four weeks. In the petition, the operators requested the tribunal to direct DoT to charge them for allocation of microwaves on revenue share basis from 2002 when the Unified Access Service License regime was implemented. AUSPI and Reliance in the petition also urged that spectrum charges should be taken from the date of commercial operations of telecom companies and not from the date of allocation of microwave. During proceedings, counsel Ramji Srinivasan, appearing for the operators, contended that after UASL implementation in 2002, DoT had assured them it would take spectrum charges on revenue share basis.

Tata Teleservices opposes DoT's plan to auction 3G spectrum to foriegn players

As per Economic times - "Tata Teleservices has opposed communication and IT minister Dayanidhi Maran’s plans of allowing foreign players to bid for 3G spectrum and said that this would lead to further scarcity of radio resources and hamper the growth of existing operators. The company which offers CDMA-based telecom services, has also alleged that the Department of Telecom (DoT) was ‘completely disregarding the recommendations of telecom regulator Trai for facilitating the progress of existing GSM and CDMA operators from 2G to 3G services’. The interests of existing telecom licence holders who have done so much to make India the fastest telecom market in the world must be protected and a level-playing field provided to them,” the company said. The company has pointed out that at present, there was shortage of 2G spectrum, and therefore the spectrum-efficient 3G network would primarily be used to provide voice services in the beginning. “The logical policy, therefore, has to be allow the entry of 2G companies into 3G to further develop their markets and to grow by getting more spectrum and by using their existing infrastructure, instead there is a move to cap the growth of the existing players completely disregarding the recommendations made by Trai...,” the company said."
Additionally, Tata Teleservices has also objected the proposals of the internal committee formed by DoT to study the 3G spectrum pricing and allocation recommendations of Trai. This committee has suggested that four telecom companies be given 3G spectrum in the 2.1 Mhz frequency, through a bidding process, while adding that if state-owned BSNL and MTNL did not figure among the top four in the auction, then the PSUs must be given 3G spectrum provided they match the price of the second highest bidder. Tata Teleservices has pointed out that Trai had recommended that only existing players be allowed to bid for spectrum in 2.1 Ghz, and that too for a quantum of 5 Mhz each. “Inviting external entities with blocks of 10 Mhz of spectrum, will not only drive the costs up, but will also limit the number of operators. Then existing licensees will be forced to conduct their operations in sub-optimal fashion with sporadic and minute allocations of as little as 1.25 Mhz at a time. The reasons for such unfair treatment must be divulged and such unfairness is clearly not going to be accepted by the industry,” the company added. On the proposal for a quota for BSNL and MTNL, Tata Teleservices said that such treatment, in addition to being against the recommendations of Trai, would also not offer a level-playing field between private and state-owned players. It has also added that BSNL and MTNL were no longer the sole custodians of public interest as the government itself had allowed civil servants and PSUs to embrace the services of private telecom service providers.

Indian regulator targets non-performing ISPs

Concerned over poor track record of Internet Service Providers, Indian telecom regulator TRAI has recommended lowering of foreign direct investment on par with telecom sector at 74 per cent from the existing 100 per cent. ISPs having 100 per cent FDI equity should be given two years for reducing foreign holding to 74 per cent, it said.

In its recommendations to Department of Telecom, TRAI has also suggested major changes in financial and regulatory levies. Instead of free entry, it recommended levying an entry fee of up to Rs 20 lakh along with a uniform licence fee of six per cent of gross revenue. ISPs seeking licence at national level will have to pay Rs 20 lakh as entry fee while it will be Rs 10 lakh for state level ISPs. The minimum annual licence fee has been pegged at Rs 5,000 for district level ISP, Rs 10,000 for state level and Rs 50,000 for national level ISP.

The regulator has taken a tough stand as the objective of competition and growth of Internet have not been met. "Out of 700 licences issued within three years of opening of ISP sector to private service providers, only 389 licensees exist on Thursday. As per the performance monitoring report with TRAI, only 135 Internet service licensees are functionally active," TRAI said.

TRAI comes out with mechanisms to ensure implementation of 3 stage redressal mechanism for Indian telcos

The Telecom Regulatory Authority of India, which last week had directed all landline, mobile and internet service providers to set up to set up a three-stage redressal mechanism and improve transparency in billing with immediate effect, will carry out surprise checks, if necessary, to ensure compliance.

Trai has directed all operators to maintain complete and accurate records of redressal of grievances by its call centres, nodal officers and appellate authorities. Trai, if necessary, will direct any of its officers or employees or through an independent agency appointed by it to inspect the records maintained by the call centres, offices of the nodal officers and the secretariat of the appellate authority.

Trai had asked all operators to three-stage redressal mechanism -
1) Call centres will be the first level of customer redressal and must address all customer grievances within a maximum period of seven days.
2) At the next level, service providers must appoint a nodal officer, whom the customer can contact if he is not satisfied with the redressal at the call centre level.
3) The third level involves a provision by which the customer can appeal to the appellate authority (within the service provider) for redressal where the authority should issue its judgement on the issue within three months.

The regulator had also directed all operators to improve the quality of their billing after its survey revealed that nearly 80% subscribers found it difficult to understand their telephone bills. Accordingly, Trai has mandated that information such as applicable tariff plan, credit limit, security deposit, methodology for calculations of various pulse rates and charges, procedures regarding payments of bills, setting up of public grievance mechanism and display of customer information box with certain information be printed in easily readable font size and be included in the telephone bills issued to consumers.

Free broadband to all Indians?

The government of India is considering a radical scheme under which it will provide free broadband and landline phone service to all Indians, paid for by billions of dollars in telecom taxes now just sitting idle in the bank.
The free broadband would be at 2 Mb/s.
In India, as elsewhere around the world, the phone companies have been reporting declining numbers of landline subscribers. The free service could start rolling out as quickly as 2009. Government owned Indian phone companies Bharat Sanchar Nigam Ltd (BSNL) and Mahanagar Telephone Nigam Limited (MTNL) would provide the free service. Those two companies already provide the vast majority of all of Indian broadband. By the end of this year they are expected to account for 7 million out of 9 million DSL lines in the country, according to Indian government plans, which call for a massive xDSL rollout this year. There were only 2.3 million CSL lines in the country at the end of last year, of which BSNL accounted for almost half.
With landline service - for those who still want it - and broadband free, India's phone companies would be expected to look to various unspecified value-added services for their revenue, according to the government plan. "The move holds the potential to kill the telecom business as we know it," said the Indiatimes.
Funding the plan, and paying for a nationwide fiber optic network to be built and run by Department of Telecom (DoT), will be India's Universal Service Obligation Fund (USOF) into which all telecom operators in India cough up 5 percent of their annual revenues. Estimates are that as of the end of March the USOF stood at over $2.2 billion, of which only part would be needed to pay for the plan.

TRAI comes out with recommendations to curb unwarranted calls by telemarketers

The Telecommunications Regulatory Authority of India (TRAI) has recommended punitive measures and the setting up of a national "Do Not Call" master telephone list to curb unwarranted calls by telemarketers. In its proposal to the Department of Telecommunications (DoT), TRAI has proposed seting up the National Do Not Call (NDNC) Registry, which will be a countrywide database of telephone numbers of subscribers who have opted not to receive unsolicited commercial calls (UCC).

Once the rules are finalized, TRAI has mandated telecom service providers to set up a mechanism - call centres or online procedures - to receive requests from the subscribers who do not want to receive such calls a statement issued by TRAI said.
It has also approached DoT to authorise the National Informatics Centre (NIC) to undertake the task of designing, installing, operation and maintenance of the NDNC Registry, the expenditure of which will be borne by TRAI itself.

To make the deterrence stronger, the regulator has suggested that violators be made to pay anywhere between Rs 500 and Rs 1000 (12-24 dollars) for every call they make, with more than three such calls resulting in disconnection of phones used by telemarketers.
The clearance from the communications and IT ministry and the Reserve Bank of India will be required for implementing the plan. TRAI's measures come after the Supreme Court, acting on a public interest litigation filed with it in 2006, had banned spam calls and asked the government to form a roadmap to control and curb unsolicited calls by telemarketers.
The court had termed unsolicited calls as an invasion of privacy and had directed the government to safeguard consumer interests.

TRAI's measures are likely to put a large number of domestic business process outsourcing companies, hired by companies to sell credit cards or home loans over the telephone, out of business. Many countries, such as the US and Australia, already have similar legislation to bar telemarketers from calling mobile subscribers.

The CTO of an Indian telecom operator can't be a foreigner ?

As per a news item reported in economic times "The government on Thursday notified the enhancement of foreign direct investment (FDI) in telecom from 49% to 74%. All companies have been given three months time to comply with the revised norms and thereafter compliance reports will have to be submitted on a six-monthly basis. The notification follows the Union Cabinet’s approval of the 74% FDI cap in March, after over 18 months of dithering on the issue. While FDI up to 49% will continue to be on the automatic route, it would require the approval of the Foreign Investment Promotion Board (FIPB) if the limit were to cross 49%. FIPB is also empowered to note that the investment is not coming from countries of concern or unfriendly entities, the government said in a statement. As reported earlier, the Cabinet when clearing the new guidelines had incorporated a series of additional norms, especially on the controversial issue of remote access (RA), to address the concerns of security and intelligence agencies as well as the defence ministry. The provision for RA will allow network majors such as Motorola and Ericsson to monitor the networks of Indian operators from locations outside the country. The Cabinet had cleared all other outstanding issues, except RA, pertaining to 74% FDI in telecom during a meeting on December 8, 2006. The guidelines allow foreigners to hold key positions like chairman, MD, CEO and CFO of telecom companies, subject to clearance from the home ministry on an yearly basis. However, majority of directors on the board will have to be Indian citizens. Besides, the chief officer in charge of technical network operations and the chief security officer have to be resident Indian citizens. Additionally, for security reasons, domestic traffic, which is identified by the licensor, cannot not be hauled or routed to any place outside India. Service providers are also required to take adequate and timely measures to ensure that the information transacted through a network by the subscribers is secure and protected. According to the guidelines for RA, telecom companies can extend this provision only from certain approved locations with prior approval from the department of telecom and other security agencies. Operators should keep an audit trail of all RA activities for a period of six months and these must be provided on request to the DoT or any other agency authorised by the government. Besides, telecom companies must also keep mirror images of such RA activities for online monitoring and provide the same to security agencies on request, and the provision of RA cannot be used for monitoring of content. The guidelines also stipulate that under no circumstances, should RA be used for lawful interception of sensitive voice and data which are specified by the government. Additionally, it also states that RA can only be provided to telecom equipment suppliers and manufacturers and the parents and affiliates of the licensee company. For extending this facility to any other company, prior approval of the DoT is required."

Ofcom, the UK regulator comes out with rules for VoIP telephony

U.K. regulator Ofcom has handed down its first set of rules for VoIP telephony - what it is calling a "code of practice" . The rules apply to "softphone" VoIP calls from PCs, such as those between Skype and landline users (via the SkypeOut service), as well as to calls using broadband-connected VoIP adapters and standard phones. In addition to Skype, which is thought to be as wildly popular in the U.K. as it is in most of Europe, major VoIP players in the U.K. include everyone from pure VoIP player Vonage to incumbent BT and major challengers such as France Telecom's Orange and Tesco.

Ofcom said that "the new code of practice requires VoIP providers to make clear:
>>Whether or not the service includes access to emergency services;
>>The extent to which the service depends on the user's home power supply;
>>Whether directory assistance, directory listings, access to the operator or the itemisation of calls are available; and
>>Whether consumers will be able to keep their telephone number if they choose to switch providers at a later date."
In cases where emergency service calls are not available - which in the U.K. is believed to me the vast majority of VoIP service - providers are being required the get consumer's positive written acknowledgement that they have been so informed. Ofcom suggested that getting them to check off a box on their service order could have that effect. VoIP providers also have to put stickers on VoIP phones warning users they can't make emergency calls and, should they try, have a recorded announcement to that effect. For softphones the warnings have to appear on the PC screen. Similar rules cover the issue of loss of service in a power outage.

Ofcoms' regulations hardly come as a surprise to the VoIP community. VoIP service providers had been fighting for years against Ofcom establishing any rules, a battle they have now lost. Ofcom began considering VoIP rules as far back as September 2004, the regulator noted in its ruling. A little over a year ago, in Feb. 2006, the it put forth its proposed rules.

While imposing its first regulations on VoIP, Ofcom also very carefully indicated its general approval of the emergence of the technology.
"VoIP services offer consumers the prospect of cheaper calls - especially for calls from one VoIP service to another - and valuable new services such as call handling and unified messaging," Ofcom wrote in its ruling announcement. "Over the last twelve months a range of new VoIP services have been launched and demand continues to grow."

The regulator also cited industry estimates that, by the end of this year, there will be some 3 million VoIP users in the U.K. That estimate may be quite low, and may not include softphone users such as those on Skype and Microsoft Messenger. In January BT put out a statement bragging of its one millionth VoIP customer, for instance, saying it hit the target a half a year earlier than it had expected.

Major deregulatory changes in Telecom sector in Canada

Canada's Government has ordered the immediate deregulation of a majority of the Canadian phone industry. Canada's major telco's have been given the right to launch a battle to regain customers lost to both pure-play VoIP houses and cable companies offering VoIP services. Predictions are for a price war in very short order. Bell Canada is said to have lost 181,000 subscribers to VoIP-based competitors in the latest quarter alone, and Telus may have lost 31,000.

The orders have been issued despite opposition from Canadian regulator the Canadian Radio-television and Telecommunications Commission. The commission had passed its own set of "market-based" rules covering the regulation of voice carriers. But Canadian law gives the minister the ability to overrule the CRTC.

Under the new rules, a telco will only have to show there are three different competitors offering phone services, including wireless, in a given residential market or two in a business market, in order to apply for the deregulation of its rates. The CRTC then has a limit of 120 days to act on the applications. Previously, telcos had to prove they had lost 25 percent of their customers before their rates could be deregulated. The new rules also eliminate the so-called "win-back" restrictions the CRTC had imposed, forcing phone companies to wait three months before trying to lure back customers who had defected.

Canada's New Government is pursuing an ambitious policy agenda for the telecommunications sector, the essence of which is a new regulatory framework that is more modern, flexible and efficient.

USO bid for setting rural telecom towers

The Department of Telecom has received bids from 22 stand-alone infrastructure providers and all telecom operators for the setting up 8,000 telecom towers in rural India at an estimated cost of over Rs 3,000 crore. The government will provide the capital to set up these towers from the Universal Service Obligation Fund (USOF) through a bidding process. All Telecom companies pay 5% of their adjusted gross revenues towards the USOF, which is used for funding telecom infrastructure in rural India. Last year, the government had allocated Rs 1,500 crore towards the USOF in the budget. As per the Economic Survey released on Tuesday, off the Rs 10,787 crore collected towards USO fund till March 2006, only Rs 4,232 crore has been disbursed so far.

BT focuses on M & A

BT's Indian joint venture, BT Telecom India Pvt Ltd, is buying BT Infonet global managed network services reseller i2i Enterprise Pvt Ltd.
The takeover is BT's 17th acquisition around the world in the past 24 months.
"BT will become the biggest foreign global carrier operating in India today as the result of this deal," BT Global Services CEO Andy Green said in a prepared statement. i2i, a managed service provider, brings a customer base of 200 corporate customers into the BT fold, and it employs more than 200 people.
The price being paid by BT Telecom India, which is a BT joint venture with local Indian company Jubilant Enpro Pvt Ltd., was not disclosed. In a hint, BT said that as of I2i's last audited balance sheet date, March 31 2006, its gross assets were approximately $22.5 million. That suggests a price of not more than, perhaps, $100 million.
While the size of the deal is believed to be relatively small in dollars, "the acquisition of i2i is exciting because it places BT at the heart of the world's fastest-growing IT and business-process outsourcing market," Green said. "This will help BT build a broad-based platform for growth in India and create a single BT-branded channel to the Indian market."
He continued, "India is a cornerstone in our global expansion plans and this investment underlines our commitment to growth from India. BT continues to execute its global mission to be the leader in the delivery of converged networked services."
Indeed, BT recently said it wants $250 million in sales in India by 2008 from its various ventures in the country (TelecomWeb news break, Sept. 14, 2006). It's been coveting an Indian phone license for years (TelecomWeb news break, Nov. 23, 2005) and, in November 2006, BT Telecom India applied for licenses to provide National Long Distance (NLD) and International Long Distance (ILD) services. The BT unit was issued Letters of Intent in December 2006 by India's Department of Telecommunications (DoT), a first step toward the award of licenses. With the acquisition of i2i, it now looks like BT picks up the coveted licenses without further ado. i2i is one of the few companies in India with licenses to provide ILD, NLD, nationwide ISP and Internet telephony services, BT notes.
The acquisition of i2i comes just five days after BT disclosed a deal to buy International Network Services (INS), a Calif.-based provider of IT consulting and software solutions. INS employs almost 900 people in 12 countries worldwide. Again, BT did not disclose financial details but said that, as of the last audited balance sheet on Sept. 25, 2005, the gross assets of INS were $49.7 million. Guesses in the industry are that BT will pay nearly $200 million for the company.
That's a pittance compared with the $3.7 billion that then-Lucent Technologies (these days Alcatel-Lucent) paid for it back in 1999, merging it into Lucent Worldwide Services as the Enhanced Services and Sales division, its enterprise professional services unit. Back then, INS was doing a reported $300 million a year in business, but demand for new network projects collapsed and INS was hit even harder due to the loss of its vendor-agnostic status. Lucent finally sold INS in July 2002, reportedly at a huge loss, creating a privately owned company by venture capitalists.
