Multichannel 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 and Australia, 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.
