Bill, Stephen,
Bluetooth has a stated bandwidth potential of up to 1 Mb/s (1,000,000 bps), and a "standards" based reach of up to 10 meters in noisy environments.
Some early implementations will leverage existing serial port speeds that already exist in some devices which are much lower, however, =/< 115 kb/s.
There are some options being considered to increase the reach up to 100 meters. Actual throughput might fall into the 0.7 kb/s range, once system- and protocol- overheads are taken into account.
BT is for local on-premises-based device synchronization, and the porting of files between devices, and maybe some ancillary messaging, as well. CDMA is a global protocol whose principal attributes transcend local device considerations, for the most part. Although, as I pointed out yesterday, CDMA can also be used in vertically integrated fashion with other CDMA devices on location, but I suspect that this will only be between devices of the same manufacture. Implied here is that BT will be used to support multivendor operation, by its very nature.
CDMA is the globally aware WAN protocol, whereas BT is the locally aware premises device protocol.
If others here know of plans (or indeed, if movement has already taken place to already implement) changes or enhancements to the characteristics I've outlined, then please advise. Thanks.
