Are there anyone here who is familiar with GPRS specs?

[Stanley Lee]

I'm trying to understand the significance with some of the specs, but don't know enough to even search properly online. I was suggested by a friend of mine to approach folks here, as some of you are quite familiar with wireless communication systems. Would be great to see if there's someone here familiar with the protocol before I send over my question.

Thanks,

Stanley

Mobile baseband firmware is a big ball of secrets.  This is where I'd start: http://bb.osmocom.org/trac/

Basically, the specs are pretty irrelevant. It’s not as though you can
read the spec, build a chip/radio, and have any hope that it’ll work.
In that market, what happens is that a few part vendors get interop
working, then the definition of “Standard” is “interops with those
vendors”. -T

Agreed! BTW: Does anyone know where you can get an Osmocom phone that
is guaranteed to work? I've spent way too much time trying to
ressurect dead Motorola pieces of crap.

As a counter-point, the old standards model got us from 2400 baud to 56k
in about 10 years, piles of doco doesn't get products out quickly and
our society regards delivery as the measure of success (not suggesting
that is necessarily a good thing).

Of course sloppy design will come back to get you eventually (just look
at the mess the industrial control industry is in over stuxnet).

GPRS means "European GSM"
www.etsi.org should have full specs for it

You might want to start here
