I would qualify this by saying that it probably depends where you
are. In Europe it tends to be grouped in the 2.5G camp, whereas in
North America it may be grouped in 3G.
Saying that it's widely recognized as 3G and leaving it at that does
not mesh with lots of examples out there (google will find them for
you) in which even vendors themselves (I checked Nortel, Alcatel,
Agilent) qualify EDGE as a "stepping stone towards 3G" or, at best,
as providing "third generation-like" services.
EDGE does not (please correct if I'm wrong) use what's
commonly referred to as 3G frequencies (2GHz), but rather it is another way
of using those frequencies currently used for 2nd generation cellular
networks (900/1800MHz in Europe, 1900MHz in North America), correct?
At any rate, the most common industry view is that (from an
Agilent site) "GPRS and EDGE are data transport mechanisms
that collectively are referred to as 2.5G wireless technologies."
By the way, Ericsson's own definition in
http://www.ericsson.com/technology/EDGE.shtml does not classify
it as 3G either.
I actually had a hard time finding an example of EDGE touted as
a 3G technology. Here it is, and in the interest of finding a
solution, would you agree with the following assessment?:
(From http://www.watmag.com/tech/GPRS_EDGE/GPRS-005.html)
EDGE is the next step in the evolution of GSM and IS136.
After the second generation of GSM, EDGE comes as the 2.5
generation (referred to as 2.5G in Europe) and, at the same
time, as the third generation of TS136 (referred to as 3G in
North America).
Perhaps we can use the above to explain EDGE in a new section
(section 3.4, as you propose), but I fail to see the Big Problem
as we what we already say seems to agree with the most commonly
held industry view.
