As was expected, none of the private telecom companies have withdrawn from the spectrum auction. All the companies which have registered for auction will participate.
They are Bharti Airtel Ltd, Vodafone, Reliance Jio Infocomm Ltd, Idea Cellular Ltd, Telewings (Uninor), Reliance Communications Ltd, Tata Teleservices Ltd and Aircel Ltd. they are in race to bid for about 403 MHz of airwaves in 1,800 MHz band and 46 MHz spectrum in 900 MHz band.
The decision of the EGoM to charge 5% for the spectrum seems to have satisfied all. Compare this with the 3% recommended by TRAI. Almost all decisions of the TRAI seems to be pro-private.
