Spectrum allocation in india: journey so far.

The Centre has set the stage for the largest spectrum auction ever. Let’s look back at the developments leading to government’s decision to auction spectrum and open up more bandwidth for the telecom industry

This, however, is not sufficient to meet the growing appetite for mobile phones and its services.

Telecom industries are now looking towards new options. S band spectrum, for instance. The frequency of radio waves in this band ranges from two to four GHz.

S band was allocated by the World Radiocommunication Conference, organised by International Telecommunication Union (ITU), in 2000 for terrestrial mobile communications services. ITU is a UN body that regulates information and communication technology issues. S band was initially used by meteorology departments and communications satellites.

Mobile phones entered India based on 2G technology (see ‘Evolving mobile technology’). Sixteen years later, demand for advanced technologies prompted the government to auction 2.1 GHz band for 3G services.

Eyes on S-band

C S Rao, chairperson of WIMAX Forum India, an industry-led non-profit that promotes use of 4G or WIMAX technology, says, “There’s not a single commercially proven, scalable and affordable consumer-driven satellite mobile service in the world. ISRO can’t keep holding on to the S-band in the name of low-scale MSS which has neither been proven nor found viable.” S-band should be put to use for 4G broadband services, he adds. A A Khan, additional general manager at Bharat Sanchar Nigam Limited (BSNL), agrees, “Satellite phone is very expensive to use, and very few people will be able to afford it.” In 2009, BSNL and Mahanagar Telephone Nigam Limited (MTNL) were given 20 Mhz each of spectrum in the S-band for wireless services by the government. However, BSNL and MTNL have not been able to utilise it. The frequency—2.3 GHz—allotted to them has neither been standardised by the International Telecommunication Union for use nor are there equipment compatible with this technology. Khan adds that they have surrendered the spectrum. “The band was sold to us forcefully and we had to pay over Rs 8,000 crore for it. Now the government says the money will not be returned until the spectrum is re-auctioned.” Sudhir Gupta, principal advisor (mobile services) in TRAI, informs that they have already recommended to the government that a part of S-band be allocated for commercial services like high-speed packet access used in 3G. “These services need a lot of spectrum and the current spectrum is not sufficient,” he adds. ISRO did not respond to the repeated queries by Down To Earth.

Spectrum wars

The new DoT policy, which came into effect on March 31, has allocated a maximum of 15 mhz to gsm   operators, such as Airtel and Hutch, and 7.5 mhz to CDMA   players, such as Reliance Infocomm and Tata Teleservices. Earlier, the maximum limits were 8 mhz for GSM   and 5 mhz for CDMA. Official estimates say Delhi will require an additional 28 mhz to sustain current telecom growth. Though the policy recommends a 2:1 ratio allocation to GSM   and CDMA   operators, it withdrew the existing condition that CDMA operators were to add more users than GSM   operators if they wanted extra spectrum. The new policy mandates equal subscriber base for more bandwidth. Ratan Tata, the chairman of Tata group, in his letter to the prime minister has brought up the issue of 'self-proclaimed subscriber base'. He is opposed to the policy of distributing spectrum on a subscriber-number basis without a proper verification mechanism. At present, Bharti Enterprises leads the GSM group with 18.5 million subscribers and Reliance heads the CDMA group with 14.6 million users. The policy has angered CDMA operators on other counts as well. DoT has ordered 2:1 ratio spectrum distribution on the premise that CDMA technology is more spectrum-efficient. But the operators claim that they are receiving the short end of the stick because of better technology. According to CDMA   lobbyists, this is against fair trade practices and the government's commitment to technology-neutral services. Each group interprets 'fair play' differently. While the CDMA group wants equitable distribution, the GSM   lobby claims a 5:1 ratio would be fairer as the spectral characteristic of CDMA technology affords it five times more capacity. In view of the arguments, CDMA operators' plea of unfairness in allocation is tenuous. Their demand for more bandwidth in spite of owning more efficient technology is contradictory in itself. The availability of spectrum to each operator will decide the company's future growth and ability to hold back competition from other players.

On the defensive

Spectrum availability has been a global problem with disputes over spectrum occupation. Defence establishments were often granted bulk spectrum in the absence of commercial demand. Now, with escalating commercial demand for more frequencies, the war over spectrum allocation is inevitable. In view of the increasing pressure for more space from the telecom operators, the prime miister constituted a high-powered group of ministers (GoM), headed by defence minister, Pranab Mukherjee, to draft a new policy and vacate spectrum space alloted to the ministry of defence. However, DoT drafted its own policy in the absence of GoM's recommendations. With the formation of the GoM, both CDMA and GSM   groups lobbied fiercely for a bigger chunk of 45 mhz of spectrum being vacated by the ministry of defence. With every move to free more bands for the telecom sector, such battles will become more frequent. The Centre recently announced that it would spend Rs 1,000 crore in opening up more bandwidth for the telecom industry. More state-owned spectrum facilities will be vacated soon. The industry accuses the defence sector of wastefully underutilising the large number of frequencies allotted to it. The defence ministry claims that most of the equipment in use was procured overseas and vacating frequencies will mean added costs. They have demanded payment from the government or the industry for the re-tuning of equipment. Sources in the industry say the Tatas are willing to pay but not Reliance. The Indian cellelur telephony sector has recorded a qrowth of 20-25 per cent and 100 million subscribers. With such an enormous growth, the controversy over spectrum allocation needs to be addressed sooner than later as the global telecom industry moves to the next generation of technology—3G—of which, visual wireless telephony comes as a starter.
