After 49 rounds, bidding in the FCC's Advanced Wireless Services (AWS-3) auction has reached $40.7 billion.
A total of 1,614 licenses total are up for auction, covering 65 MHz of spectrum in the 1695-1710 MHz, 1755-1780 MHz, and 2155-2180 MHz bands ("AWS-3" bands).
The 1695-1710 MHz band is authorized for low-power mobile transmit (i.e., uplink) operations only. The 1755-1780 MHz frequencies in the paired 1755-1780/2155-2180 MHz band are authorized only for low-power mobile transmit (i.e., uplink) operations; the 2155-2180 MHz frequencies are authorized only for base station and fixed (i.e., downlink) operations. Mobiles and portables in the 1695-1710 MHz and 1755-1780 MHz bands may only operate when under the control of a base station, and AWS-3 equipment is subject to a basic interoperability requirement.
