Multichannel Multipoint Distribution ServiceMultichannel multipoint distribution service
, also known as MMDS or wireless cable, is a wireless telecommunications
technology, used for general-purpose broadband networking or, more commonly, as an alternative method of cable television
programming reception. MMDS is used in the United States
and other countries, including Ireland
, usually in sparsely populated rural areas, where laying cables is not economically viable.
The MMDS band uses microwave frequencies from 2 GHz to 3 GHz in range. Reception of MMDS-delivered television signals is done with a special rooftop microwave antenna and a set-top receiver box for the television receiving the signals. The receiver box is very similar in appearance to an analog cable television receiver box.
