Multichannel Multipoint Distribution Service or MMDS has been dubbed "wireless cable TV". It provides digital video- and Internet- (including VoIP) access using various over-the-air microwave frequencies. Services are provided within a terrain-dependant line-of-site area, up to about 20 miles or 32 km from the transmit site. MMDS is especially suitable when services similar to those provided by a modern digital CATV system are needed in areas without any existing infrastructure.

Wireless cable systems can be implemented inexpensively. The capital cost for a single system may be as little as $US 1.0 to $US 1.5 million dollars with additional hubs costing about $US 300,000.00 to $US 500,000.00 each. Subscriber equipment typically costs between $US 250.00 to $US 500.00. Total installed costs are influenced by the country, the existing infrastructure and services to be provided.

Depending upon the country or region, MMDS is known by a variety of names (sometimes with slightly different technical specifications) including:

MMDS is part of the family of direct-to-home broadcasting technologies. Like DBS, the customer receives an encrypted signal with a small antenna and IRD (set-top box). However, unlike DBS, full duplex (bi-directional) digital services can be easily and inexpensively accommodated for Internet and VoIP services.
