MMDS stands for Multichannel Multipoint Distribution Service. This is a specification that uses broadband wireless technology and a point-to-multipoint structure. This means MMDS uses a single antenna which broadcasts to several receiving antennas. MMDS makes use of Ultra High Frequency (UHF) communication.
MMDS operates on frequencies licensed by the Federal Communications Commission (FCC). The said government agency divided the US into separate basic trading areas with MMDS bands in each area. To regulate MMDS, the FCC sold to certain providers the transmission rights for the MMDS bands in each basic trading area. Apart from USA, other countries that use MMDS include Canada, Ireland, Mexico, and Russia.
MMDS presents several specifications for companies providing the service. The maximum bandwidth of MMDS is 10Mb with a range of 70 miles. Its band uses microwave frequencies ranging from 2.5GHz to 2.686Ghz. To achieve data transport security, MMDS performs Triple DES, a Data Encryption Standard, on the traffic flows between the wireless modem and the Wireless Modem Termination System (WMTS). These components are found in the network of the provider’s main station.
Aside from being used in programming receptions for certain cable television systems, MMDS is also used in broadband networks. Its high speed data transfer capability enables users to acquire more information in less time. In both cases, since users do not need to acquire wires for their cable TV or Internet access, MMDS entails relatively lower costs.
MMDS also adapts the Data Over Cable Service Interface Specification (DOCSIS). DOCSIS defines standards involved in cable modems and equipment that support high speed transfer of data.
