Hi
John,
I fully agree
with the need for Repeaters, but there are alternate solutions to resolve the
problem, with lower deployment cost.
I suppose
that you call "Repeater" a radio-DSP based device, but a solution can be based,
as I written already, on a Stand Alone AU working in the same sector
frequency.
The KTF
solution was based on fiber between Base Station and Repeater (extremely costly,
will need special fiber deployment) and had in mind the 3G centralized approach;
we target a full IP Network, the new system architecture will allow other
solutions.
The
Requirement document does not address the System Architecture, at networking
level. This is essential, to further enable the discussion of System
solutions.
In
conclusion, we need a mandatory solution for optimal coverage of radio
"holes". I would not use the word "Repeater", may be
mis-leading.
And support
of very large delay spreads should be avoided. It has cost implications.
Regards,
Marianna
Joanne et al.,
Support for the use
of repeaters needs to be a mandatory requirement because operators need to
have this tool in their tool box to economically provide in-building coverage
and in lightly populated areas. If you recall from the presentation in
Singapore that KTF uses allot
more repeaters than base stations in their network. The same trend is also
occurring in the US.
The impact on the AI
is that the system has to support larger delay’s and delay spreads.

802.20 Requirements - Repeaters
It's not
clear to me the AI design implications of the changes you have made.
However,."should support" implies that
support
for repeaters is optional. Changing to "must not preclude" makes it a
mandatory requirement. This change,
at least
to me, doesn't clarify the rationale so much as changes requirement
itself. I support maintaining the previous wording of the requirement
until we have a better understanding of the implications of the change and the
rationale for such.
