Jon,

Interesting information. Thanks.

IMHO the best thing about digital was the sound quality improvement (too many
noisy analogue calls) and the integrated services like SMS and caller ID.
(SMS: Short Messaging Service on GSM.)

This sounds like a function of the codec and the bit rate, rather than
CDMA in particular. Original GSM quality was quite good, but phones in
the last 2-3 years have had an "Enhanced Full Rate" feature which produces
significantly better audio.

With suitably spaced base stations and a decent bit rate, CDMA should
be no different to GSM, as far as I can see. I don't work in this area
though, rather just an end user.
