Jon - good guess! ========== "It is important to note that Band 2, the EV-DO band, devotes its full capacity to just one user at a time. Time Division Multiple Access (TDMA) techniques allow multiple users to share the band. In a TDMA process, each user commands the entire data-only channel for a few milliseconds, and then the same bandwidth is switched to another user, then a third, and so on to the maximum capacity of the channel." base-earth.com It's a very positive article.

Jon, re "1xEV-DO user # 1 ties up the network from 0 seconds until 0.01481 seconds." Nice WAG at a number there. <g> That's representative .. but if user #1 is the only user on a DO rf channel, user #1 has 100% of the channel's data capacity (2.4 Mbps). Found this definition of 1xEV-DO on Andy Seybold's site at outlook4mobility.com "This is the next EVolution of cdma2000. “DO” indicates Data-Only and this system is capable of data speeds of up to 2.4 Mbps. This upgrade to cdma2000 requires *a second 1.25-MHz channel* that is *used exclusively for data. Most cdma2000 network operators are expected to combine 1x and 1x EV-DO channels in their systems to provide varying voice and data capacities as required by customer demand." Emphasis() is mine. Ron
