Thanks, is there any map on the web on the "whole picture"??
(New Orleans, etc gaps)
EDGE:
Technically it should be "good enough" with a handset
which is EDGE only for receiving data, the
tough RF demands only on the basestation transmitter.
(which is tough anyway)
I have not checked if this is clearly included in the
standard, do you have any idea.
That is, I have assumed it would be "obvious", for example
just to save battery by keeping the handset transmitter
in basic GSM mode, less wasted bias,etc. when no large
amounts of data is transmitted.
(on the other hand one transmits 3x data in the same time,
also saves battery)

Btw, another interesting aspect, maybe, is how to
"clean up" the interference from neighbouring,etc
cells on that same carrier and timeslot. (just to avoid
to just focus on the PA amplifier)
My point that a "smooth" tranisiton should be possible,
one step at a time, network planning, more dynamic
capacity allocations, gradually handsets,etc..
What it also makes me think of is how the 900/1800 duo
system was marketed, by buying a new duo-phone one got:
- slightly lower costs per minute, either only in
duo-regions or even everywhere (carrot instead of stick)
(- plus the lesser chance of "busy" on the then crowded 900MHz band)
Would work for GPRS/GRPS-EDGE Data, more complex for voice.
Anyway, gives a good mechanism for lowering costs for
data and replacing legacy pool of handsets. |
