The Indian Army and Navy which occupy spectrum in the band of GSM communications is refusing to vacate until an alternate arrangement is made. Air Force has agreed to vacate the spectrum because BSNL is providing them a Optical Fibre network for their communication needs.

The Indian Air Force will vacate 40 MHz of spectrum which will take care of immediate crunch. TRAI has already invited expert opinion on capping number of operators per circle and how to effectively use the scarce spectrum in an era of unified communications breaking the barrier between GSM and CDMA.

In a separate note, the TRAI study has found that Indian mobile communications network congestion is rising since its last study in Dec-2006.
