The Federal Communications Commission (FCC) advanced its efforts to make spectrum available for voice, data, video, and other wireless broadband services offered over 3G mobile networks. Order FCC 05-149 modifies the band plan (originally adopted in October 2003) and licensing and service rules for the 90 MHz of Advanced Wireless Service (AWS) spectrum at 1710–1755 MHz and 2110–2155 MHz.

The new band plan splits the original 30-MHz E block at 1740–1755 MHz and 2140–2155 MHz into one 10–MHz block (new block E) and one 20–MHz block (new block F). It also restructures the band plan by aligning the CMA, EA, and REAG spectrum blocks. In addition to the changes made to the AWS band plan and geographic licensing areas, the order removes a restriction on transmitter output power levels. www.fcc.gov
