Re: How to measure GPRS connection speed?
Whoa!
I have tested EDGE and gotten over 110k ACTUAL
Where do you get those figures from?

Re: How to measure GPRS connection speed?
Read the entire context. This is for an Extended Range cell.
I typically get 150+ Kbps on a normal cell with EGPRS(EDGE) Class 10.

At the very least, it's worth a shot.

Impossible to tell without trying. Available data transmission rate
for UMTS depends a lot on signal/noise ratio and available capacity in
the UMTS cell.

Impossible to tell without trying.

It helps, especially for a directional antenna.

It will degrade both the received signal power and the signal/noise
error ratio. Haze, fog and rain will all severely degrade your radio
signal, especially for the higher frequencies (GSM 1800 and UMTS, for
example). Each object between your UE and the base station will absorb
or reflect some of the signal, which means the signal power will be
weaker once it reaches your UE.
