The TRAI had also recommended that entire 2X60 MHz in the 2100 MHz band should be made available for commercial use.

"If required, Defence may be assigned spectrum in the 1900 MHz band (1910-1920/1980-1990 MHz). It was further recommended that this matter is of utmost importance, therefore it must be taken up at the highest level and the vacant 3G slots should be put to auction along with the spectrum in 900 and 1800 MHz bands," TRAI said.

TRAI had already recommended the reserve price for 900 MHz and 1800 Mhz bands, the auction for which is scheduled for February 2015.

Regarding 2300 MHz band, for which auction was conducted in June 2010 and and two blocks across the 22 service areas were sold, TRAI said even after four and half years of assignment of airwaves, no telecom operator has actually done any worthwhile rollout.

"Therefore, the Authority would like to know if in spite of such poor utilisation of earlier auctioned spectrum even after more than four years, the DoT believes that there will be takers for this spectrum at this point of time," TRAI said.

On 2500 MHz band, the Telecom Regulatory Authority of India (TRAI) said the decision on harmonisation of this band is pending for an inordinately long time.
