Again, I stand corrected. It is EDGE Evolution. Any chance we will be
seeing this in Uganda?
http://en.wikipedia.org/wiki/EDGE
"*EDGE Evolution*, added in Release 7 of the 3GPP
<http://en.wikipedia.org/wiki/3GPP> standard, provides reduced latency
and potential speeds of 1Mbit/s by using even more complex coding
functions than the 8PSK originally introduced with EDGE."
EDGE Evolution
EDGE Evolution <http://en.wikipedia.org/wiki/Evolved_EDGE> improves on
EDGE in a number of ways. Latencies are reduced by lowering the
Transmission Time Interval by half (from 20 ms to 10 ms). Bit rates are
increased up to 1 MBit/s peak speed and latencies down to 100 ms using
dual carriers, higher symbol rate and higher-order modulation (32QAM and
16QAM instead of 8-PSK), and turbo codes
<http://en.wikipedia.org/wiki/Turbo_code> to improve error correction.
And finally signal quality is improved using dual antennas improving
average bit-rates and spectrum efficiency. EDGE Evolution can be
gradually introduced as software upgrades, taking advantage of the
installed base. With EDGE Evolution, end-users will be able to
experience mobile internet connections corresponding to a 500 kbit/s
ADSL service."

makes sense.

Nope. EDGE theoretically maxes out at approx 480 kbps. Average
supported data rate is approx 240 kbps though.
