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.
