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



Dan,
 
Thank you for acknowledging my suggestions.  However, I have proposed an alternative to your text which
includes options beyond those that "augment the radio signal in areas within the boundary of a cell." Coverage is coverage, and proposals should be able to include options like pico-cells that can provide coverage to otherwise
hard to reach areas and may be more cost effective and/or have better performance characteristics than repeaters and relays. So, I continue to disagree with the text you provide which, in my humble opinion, is not as flexible as what was sought by various respondents to the reflector.   For the ease of the reader, I will restate my proposal:
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.
Best regards,
 
Joanne

All,
 
Marianna and Joanne have provided some good suggestions which I have incorporated in the following revised definition:
 
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 relays, leaky coax etc. that rely on the BS they extend from for backhaul communications as well as Micro/Pico cells that do provide their own backhaul connectivity. 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 as well as delayed transmission.

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.
