Telecom companies have challenged in court the government's decision to impose one-time spectrum charge and the matter is sub-judice.

The move to allow sharing of all kind of airwaves held by telecom operators for mobile services, if approved by government, will benefit incumbent players like Airtel, Vodafone, Idea Cellular, Reliance Communications, Aircel and Tata Teleservices to bring down cost of spectrum ownership - a key component for providing mobile and other wireless services.

The regulator is expected to allow operators to share same set of even 3G spectrum or same set of 4G spectrum but may not recommend sharing of inter-band spectrum like sharing between 3G and 4G. At present, sharing of 3G spectrum is barred.

Telecom operators currently have been allocated airwaves frequency in 800 megahertz (CDMA), 900MHz, 1800MHz , 2100MHz (3G), 2300MHz and 2500MHz (4G) for wireless telecom services.

Trai may recommend the DoT to levy one-time non-refundable fee of 50,000 per operator for each service area in which they opt for spectrum sharing.

The regulator may restrict sharing of spectrum to only telecom operators and count 50 percent of spectrum being shared under spectrum cap rule.

The recommendation of Trai will be studied by the DoT and placed before inter-ministerial panel Telecom Commission (TC) for their decision.
