Dan,
Sorry,
I missed it. That's what happens when doing email at 2:00 am.
Thanks for pointing that out.
Now
that I've re-read the text (after a good night's sleep) I support
this version.
Best
regards,
Joanne
Joanne,
Micro and Pico cells ARE included in the
definition. I believe the revised definition is now comprehensive enough, but,
it would be useful to hear the opinions of other people as
well.
Dan
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

Technologies - Definition of
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
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.

communications - technologies that augment the radio

the BS/MS transmit signal is obstructed and significantly
attenuated by terrain or man-made structures. Such
