In the recently ended auction, only Airtel, Vodafone and Idea (the so-called incumbents or infamous A-Vo-Id group) have spent money to grab more 3G spectrum. Well the 3G spectrum term is wrong, it's 2100MHz band, generally to be used for 3G/UMTS/WCDMA/HSPA/HSPA+ services.
Aircel, Reliance Communications or Tata Teleservices/Tata Docomo did not acquire any new pie for 3G. Even Reliance Jio skipped 3G spectrum.
