Summary
Fixed wireless technology can be a simple and inexpensive way for operators to reach customers.
Unlicensed systems can use the international ISM (Industrial, Scientific, and Medical) band, and are usually based on the IEEE 802.11 wireless LAN standard.
MMDS and LMDS are multipoint systems that can be used to form fixed cellular systems. MMDS has a long-range but relatively low bandwidth. LMDS has a shorter range and higher bandwidth.
Laser beams do not require a license and offer far higher capacity than other types of fixed wireless, but they can cover only short distances.
