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.
