Local Multichannel Distribution Service - LMDS Local Multichannel Distribution Service - LMDS
Local multipoint distribution service is wireless broadband distribution system that operates in the 28 GHz to 31 GHz frequency band. In the United States, LMDS entered into the FCC auction process in 1997. LMDS uses approximately 1.3 GHz wide spectrum band at around 28 GHz. This provides a typical data rate for each LMDS channel of 1 Gbps. Because of the extremely high frequencies used, the transmitter must be located within 3 to 5 miles of the receiver. The limitation of short distance is that LMDS signals from one antenna will not interfere with other antennas placed 10 or more miles apart. This allows the radio bandwidth to be reused (frequency reused) in a cellular like fashion.

This figure shows a LMDS system. This diagram shows that the major component of a wireless cable system is the head-end equipment. The head-end equipment is equivalent to a telephone central office. The head-end building has a satellite connection for cable channels and video players for video on demand. The head-end is linked to base stations (BS) which transmits radio frequency signals for reception. An antenna and receiver in the home converts the microwave radio signals into the standard television channels for use in the home. As in traditional cable systems, a set-top box decodes the signal for input to the television. Low frequency wireless cable systems such as MMDS wireless cable systems (approx 2.5 GHz) can reach up to approximately 70 miles. High frequency LMDS systems (approx 28 GHz) can only reach approximately 5 miles.
