Techopedia Explains Local Multipoint Distribution Services

The LMDS service usually operates over a range of about 1.5 miles but distances of up to 5 miles are possible. It is point-to-multipoint technology enabling communication to and from a single source to several receivers. The receivers do not typically communicate with each other, only with the source.

LMDS was originally targeted as a digital TV transmission medium. Later it was a wireless cable solution to provide high-speed broadband Internet connections to homes. However, many vendors simply abandoned LMDS and did not produce equipment to support it. It is unlikely that LMDS can make a comeback despite its potential. It has now been overtaken by newer technologies like WiMax and fiber-to-home. LMDS is now used in a few deployments in Europe, mainly as a backbone medium for connection of mobile telephony units on global system for mobile communication (GSM) and universal mobile telecommunications system (UMTS) services.
