Advanced Wireless Services

The Advanced Wireless Services (AWS) is in the 1710 – 1755 and 2110 – 2155 MHz spectrum range. The most common use of AWS spectrum is fixed and mobile voice and data services, including cell phone, text messaging, and Internet.

The AWS band uses microwave frequencies in two segments: from 1710 to 1755 MHz for uplink, and from 2110 to 2155 MHz for downlink.The service is intended to be used by mobile devices such as wireless phones for mobile data, video, and messaging services. Most manufacturers of smartphone mobile handsets provide versions of their phones that include radios that can communicate using the AWS spectrum. Since for downlink AWS uses a subset of UMTS frequency band I (2100 MHz) some UMTS2100 capable handsets do detect AWS networks but cannot register on them due to the difference in uplink frequencies (1710–1755 MHz for AWS vs. 1920–1980 MHz for UMTS2100).
