Eric: The mystery is still handset availability.
Yes, I didn't claim the article gave all the answers
of the future :)
The handsets might actually be technologically simpler,
only one channel to transmit. The base station must
handle many at the same time, more demand of
RF parts, but also more resources, cost, power,etc..
And just like with GPRS, few need to transmit EDGE
speeds, all need to receive EDGE speeds, which puts
even less demand on the handset.
Another one important factor, pointed to in the Nokia
paper, is that basic cell allocation of channels
is based on the fact that non-EDGE works with more
intereference from neighboring cells compared to
EDGE.
However, the complexity of the solution is in a way
the same as what CDMA must handle with multiple neighboring,
overlapping cocktailparties, but easier to handle, debug
and monitor, optimize for.
(the trick of Dr J, to compare apples and oranges, old and
new)
One important factor is that not even Telia got 3G licence
in Sweden where the beuaty contest became of game of
who offers more base stations than the rest.
Instead, they have voiced their plans to go the GPRS
route on existing spectrum.
