I use my phone (GSM) now with my Notebook at 9,6 kbps, but this is circuit switched (so 9.6 kbps per "channel"). BTW I am trialling a GSM data card (basically another phone and number) that resides in the PCMCIA slot of the Notebook. Although 9.6 kbps is slow to surf the Net, it is okay for these threads! The move to GPRS next year will mean new phones, not available now to handle packet switching. An operator will have the chance to pre-set the priority of data vs voice switch. GPRS is set to go up to 115 kbps (although it could go higher). As it will be packet switched the only detrimental affect is everyone is sending or receiving information at the same time...this of course is unlikely, although bottle necks will occur (particular if an operator offers cheaper rates at one certain time of day for example). The impact on capacity is therefore not as bad as the data rate would suggest. I can imagine less voice traffic and more email, so actually capacity would in affect increase. Strange isn't it? The evolution to EDGE (at 384kbps in 2001) is more about boosting the propagation of the signal, someone once explained it to me and I know what it is meant to do, but I find it hard to explain to someone else without graphics (sorry). When the higher data rates arrive, so will the new phones...but who will be the first is an interesting question (I know who Tero thinks will be and as I hang out here you can guess who I think...to confound us both, watch out for Motorola!!). CDMA does indeed have an inherent advantage with capacity, but that is the nature of code division. However, I would guess because code division is probably the most efficient any increases in data rates would affect capacity more than TDMA based systems. The point being TDMA based systems are going packet switched (and therefore an increase in capacity because there is no redundancy, i.e., only data is sent when there is data) and how I view it, CDMA is virtually already there (so there will be no increase). It is best ask the engineers on the Qcom thread though, they might get a bit too technical but they know their stuff.
