stds-80220-requirements: 802.20 Requirements: Coverage Enhancing Technologies - Definition of



All,
 
As requested in the last System Requirements CG call, a definition of the term "Coverage Enhancing Technologies" is proposed below.
 
 
Coverage Enhancing Technologies:  In the context of wireless communications -  technologies that augment the radio signal, in areas within the boundary of a cell,  where the BS/MS transmit signal is obstructed and significantly attenuated by terrain or man-made structures.  Such technologies employ devices such as repeaters and relays that rely on the BS for backhaul communications. The term Repeater typically refers to an analog device that amplifies and retransmits the original transmission (without frequency translation). A Relay (analog or digital) typically retransmits the received signal in another frequency. A digital relay (or regenerator) decodes the information from the received signal, regenerates and retransmits it. In the case of packet communications, relays may also perform Layer-3 functions.
