The US Federal Communications Commission (FCC) established MDS (multipoint distribution services) in 1972 for the primary purpose of transmitting business data. Once in service the spectrum became increasingly popular for transmitting entertainment programming, but was limited in channel capacity. Unlike conventional cable, MDS bypasses the need for a VHF coaxial distribution network and is designed to reach its subscriber base directly with a broadcast transmission.
In 1983 the FCC added eight more channels to MDS, establishing the current MMDS spectrum allocation (31 NTSC channels: 2.5 - 2.7 GHz). Many countries around the world have subsequently adopted the use of the part of the spectrum for MMDS transmission. With the advent of digital compression equipment (6:1 compression increases the channel capacity to +100) the viability of using this technology as a low-cost alternative to hard-wired cable services was established.
