new entrant in a service area where it does not hold spectrum. Airtel, Vodafone and Loop Mobile will also be considered as new entrant for making bids in 900 Mhz band.
All bidders interested in buying 900 Mhz band- which gives double coverage compared to signals transmitted in 1800 Mhz band - will have to buy minimum of 5 Mhz of airwaves.
A company (in both band categories) can hold up to 25 per cent of spectrum assigned to all companies in a service area and up to 50 per cent of airwaves (allotted to all companies) in a particular band assigned in a service area, the NIA said.
For the first time in spectrum auction, NIA mentioned about allowing of spectrum sharing, mergers and acquisitions and spectrum trading for which detailed guidelines will be announced later.
On spectrum sharing, the NIA said companies who buy spectrum through the auction will be able to share airwaves for providing mobile phone services.
