| NOTE: I apologize - this has nothing to do with Cisco, anymore, and I think I
have gotten the answer for the original VoIP question, so this message is
just to publicly acknowledge and thank Eric for his replies. Any
further/follow-up discussions on this subject - if Eric will decide to do
so - will probably have to be moved off-line.

Eric,
Thanks again for the explanation. I have probably used the wrong terminology -
the way the vendor has explained this to me was that the main site would have
the capability of communicating with all other seven w/13-14 Mbps/ea, which
implies, then, a sort of "array" of APs at the main location (or an AP
capable of working with multiple?!?), and then an AP per each site. My main
worries are related to:
- how would this happen, w/out interference of any sort (e.g. I have two sites
which are alongside each other, "in the way" to the central location)? Would
prioritization still work (is this some sort of collision avoidance mechanism
+ identification of priority channel for each AP-AP conversation,
separately?!?)
- what would happen if someone else sets up a similar configuration, in
the "path" between one of my sites and the central one?
Again - I am not sure how to term the above configuration, as far as its
components, as well as not being sure what motorola has done to address the
issues above.
I guess I will have to pay for a test (the vendor seems to offer an option of
try-and-buy-if-it-works as advertised), but I need some reading on the
technology before I understand what the implications would be.
Thanks,
Stefan
P.S.
