The government will conduct another auction before March to find buyers for unsold spectrum after the lacklustre reponse to the auction of 2G airwaves that was wrapped up in just two days. An Empowered Group of Ministers (EGoM) led by Finance Minister P Chidambaram will meet soon to decide on the price and date for auction of spectrum in circles like Delhi and Mumbai, Telecom Minister Kapil Sibal said Friday.
