I think that the UK networks O2 and Vodafone use the 900Mhz band, while Orange, T-Mobile, and Virgin use the 1800Mhz one - someone correct me if I'm wrong and got those the wrong way round!

By the way, what is the CDMA band? I've never heard of it before!

There are three common technologies used by cell-phone networks for transmitting information:

Frequency division multiple access (FDMA)
Time division multiple access (TDMA)
Code division multiple access (CDMA)

The first word tells you what the access method is. The second word, division, lets you know that it splits calls based on that access method.

FDMA puts each call on a separate frequency.
TDMA assigns each call a certain portion of time on a designated frequency.
CDMA gives a unique code to each call and spreads it over the available frequencies.

The last part of each name is multiple access. This simply means that more than one user can utilize each cell.

So is this different and/or better than the system used here and in other countries?

From what I think I know (I could be totally wrong, but I'm simply putting info that I've picked up along the way together), CDMA has always been faster than GSM (data wise), with the 3G and all that good stuff, which is why GSM networks had to create the EDGE (to increase data transmission speeds).
