Mobile phone operators want reallocation of the spectrum. Say ISRO is wasting the resource
Eyes on S-band
Recently, four former Indian Space Research Organisation (ISRO) scientists, including a past chairperson, were blacklisted for their role in the controversial Antrix- Devas deal. They had sold part of the S-band spectrum at a low price to Devas Multimedia Private Ltd without informing the Space Commission. This spectrum was given to ISRO by Wireless Planning Commission (WPC) under the Department of Telecommunications for mobile satellite services (MSS). It was to be utilised for satellite phones.
But even years after it was given to ISRO, the band has remained unutilised. Mobile operators have been lobbying for part of this S-band (2.5 – 2.69 GHz) as an extension for 3G services. They say S-band is a limited natural resource available to the country and it should not be wasted. ISRO has been unrelenting.
“What we’re saying is that allocate more S-band spectrum for terrestrial mobile services. The spectrum allocated for MSS is currently unutilised,” says Rajan Mathews, director general of Cellular Operators Association of India. Its use will strengthen information infrastructure and 3G services, he adds.
How S-band can improve services
G L Jogi, assistant director general with Telecom Engineering Centre, an organisation that frames specifications for telecom instruments in New Delhi, explains, “2.1 GHz is the preferred band for 3G operations worldwide and operators have rolled out 3G networks in this band. However, the band is limited.” He adds that in India the band is in short supply because there are many users and service providers. Operators thus get less spectrum and this affects the quality of service. “So, additional bands are required and 2.5 GHz forms an attractive preposition,” he says.
According to the Telecom Regulatory Authority of India (TRAI), India had 670.6 million mobile subscribers in 2010. India is expected to have around 400 million 3G connections by the end of 2015, as per Wireless Intelligence, a global database for mobile market. This will be 30 per cent of total mobile connections in the country.
Satellite phones a waste
Experts also argue that promoting satellite phones is unwise. Instead, S-band can be used for 4G.
