Advanced Wireless Services
AWS-1, often incorrectly stated as 1700/2100, is a wireless telecommunications spectrum band used for mobile voice and data services, video, and messaging. AWS-1 is used in the United States, Argentina, Canada, Colombia, Mexico, Chile, Paraguay, Peru and Uruguay. It replaces some of the spectrum formerly allocated to Multipoint Multichannel Distribution Service (MMDS), sometimes referred to as Wireless Cable, that existed from 2150 to 2162 MHz.
