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



Dan,
 
I find your definition of a "Coverage Enhancing Technology" as being essentially a repeater.  My understanding of the email discussion is that people were looking for more flexibility in how proposals address coverage holes.
Instead, I propose an alternative, more flexible definition which includes repeaters and other approaches:
Coverage Enhancing Technologies (CETs), are technologies that can provide radio coverage to places that are hard to reach from macrocellular base stations. Examples of CETs include, but are not limited to, repeaters, store and forward relays, microcells and pico-cells, and leaky cable systems (which are typically used in tunnels), etc.
I also don't think we need to define repeaters, relays, etc. as they are standard within the industry.
 
Best regards,
 
Joanne

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.
