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.
