"The DoT expects to complete Phase I of spectrum harmonisation in three months. This will free at least 150 Mhz of airwaves for mobile services in 1700-2000 Mhz band," an official source told PTI.
As the Phase I of spectrum harmonisation covers six-seven telecom circles for 1700-2000 Mhz bands, the 150 Mhz quantum of radiowaves would be available in those areas initially.
The release of 150 Mhz of spectrum by the Defence to DoT is pending since 2009.
Under the harmonisation process, all ministries were required to identify spectrum as per their use and timeline by when they can vacate the excess spectrum by January 2016.
DoT and the Defence Ministry had signed a memorandum of understanding in 2009 to get some spectrum freed from the latter for commercial mobile telephony services.
In return, DoT had committed to set up an exclusive defence network for its communication services.
