NEWS: AT&T "sprucing up" EDGE Network.

In time for the iPhone and users wanting to stream video of Paris
Hilton getting out of jail, they are improving the EDGE network so its
real world speeds may be improved from 40 Kbps to 80 Kbps,
still way less than advertised "upto 200 Kbps", but an improvement
never-the-less.

Actually the official EDGE standard states that the typical rate is 144
Kb/s with a maximum of 384Kbps, though technically the maximum data rate
is 473.6 Kbps.

I remember when someone was insistent that EDGE was really 3G, something
that even Cingular never claimed. The actual data rates on Cingular EDGE
turned out to be about 1/10th of the highest possible rate.

Even out in my fringe area, I see 8K uploads and downloads on EDGE.
I was seeing 3-4K on GPRS, before EDGE was implemented.
In the city, I get around 10KBpS. My V551 isn't capable of full speed.

In the article, it notes "Real-world usage ranges anywhere from 30 to 160
Kbps.", which is mixing GPRS with EGPRS. The "internal employee" is
referring to backhaul, not how much an individual user can get on the
system, unless it's busy. That backhaul would be more important for 3G,
where multiple users would be starving for backhaul.

The comment about moving from 40 to 80 might be average throughput of
all users on towers that need more backhaul.

Are you using the right units?

Kbps is Kilo bits per second.

KBps is Kilo Bytes per second.

I think so.

EGPRS(EDGE) speeds have been consistently fast here in the San Francisco
Bay Area all along (as I've documented here) _if_ you have a device of
the proper EGPRS Class (10 or 12).

[sigh] EGPRS(EDGE) depends both on the device class and the multislot
class deployed by the carrier, so those numbers are meaningless. I've
documented the actual speeds achievable on Cingular in prior posts here.

>I remember when someone was insistent that EDGE was really 3G, something

EGPRS is really 3G, as I've also shown in prior posts.

>The actual data rates on Cingular EDGE
>turned out to be about 1/10th of the highest possible rate.

Actually consistently close to the maximum possible given the multislot
class of the deployment.

It's actually rubbish, not terribly surprising given that it's just a
blog.
