I looked for what you asked on my phone. What I found was a setting for the bands.
From the Mot web page for the phone
"Bands : GSM 850/900/1900 MHz networks"
Mine is set for automatic.
Unless I'm confused I think this is the speed it refers to. I think how much difference you might get from one of these to another might depend on several factors. Line of sight, density of stuff in between, distance, possably usage I.E. voice or data, and probably other factors.
You might want to search the internet on this.

Enter country > put V180 in search bar
Moto website where you can find the v180 electronic handbook can be DLed there as well. I like that better than the print because you can do a search.
I have been using my Motorola v180 with T-Mobile for a few months now, and while the reception is not on par with that of CDMA networks, that is to be expected from GSM. What I am curious about is a feature I found under Menu->Settings->Network->Network Setup
It is simply called 'Speed' the options are Slow, Medium (Default), Fast, and Continuous. I'm assuming that it has some relevancy to the frequency with which the GSM packets are sent? I tried bumping it to Fast and looking for a notable call quality increase (still generaly poor, as I have felt is a trend somewhat with T-Mobile, specificaly its building penetration... ug)unfortunetly I feel the only change was a slight placebo effect. Does anyone know anything specific about this option? Or more importantly, any options I might try to increase call quality? (bars are fine, I can have them at full or one from it and still get static in calls.)
