Analog CDPD only offers 4.6-9.9 k data rates. I would not think this supports I mode. Why not? DoCoMo's current system only supports 9kbps. But I really don't know what AWE will use to get their i-mode up and running. Funny thing is, I don't even care. <ggg> Let them work on their melting pot of a network and throw all kinds of money at it. Sooner or later AWE will go away just like i-mode and wap. best, MicroE

Analog CDPD??? CDPD is a digital technology, offering 19.2Kbit/s raw data rate. It uses AMPS on the airlink. The actual data rate experienced by the application (i.e the 'payload' data rate) is variable, depending on the configuration of the protocol group, how busy the AMPS network is etc. Your figures of 4.6-9.9k are a surprise. The lowest data rate I've seen in practise was 8kbit/s, in a lab during a stress test. Data rates in the field were around 13kbits/s. The actual data rate for i-mode, 1x, and any other packet based service is similarly variable. BTW As people migrate from AMPS to pure digital technologies, higher CDPD data rates should be expected.
