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.
