These fixed wireless technologies include both radio frequency (RF) and infrared (IR) options. RF solutions include Local Multipoint Distribution Service (LMDS), Multichannel Multipoint Distribution Services (MMDS), and Worldwide Interoperability for Microwave Access (WiMAX). Free space optics (FSO) systems are wireless optical transmissions using wavelengths in the infrared range. The technologies supporting broadband performance to an individual user are sometimes known as broadband wireless access (BWA) and include all of the above. See also airwave transmission, BWA, FSO, IR, LMDS, local loop, MMDS, RF, and WiMAX. |
