It has a nominal gross speed of 1 megabits per second but only 750 kbps in what counts. And don't forget, Bluetooth is designed to talk to all kinds of devices whenever they come into range. Its functionality would be limited if it didn't. But each of these conversations uses up some of the precious overall bandwidth, making the real-world numbers quite a bit worse that 750 Kbps. Why does anyone want Bluetooth when they can have 1xEV? With power control, a cellphone could send the most microscopic whisper direct to a corresponding ASIC in a nearby device. We are back to the old idea of a web of CDMA devices which can all talk directly to each other [if close enough] without going via a service provider base station and billing system. I'm not sure what terms apply to spectrum rights, but perhaps using spectrum in one's own home or business should not require the approval of the spectrum holder. If devices were limited in power, perhaps they could use the spectrum as they like. Anyway, if the power was low enough, the owner of spectrum wouldn't be able to do anything about people whispering to each other's devices below the detection threshold of the spectrum owner. They couldn't enter one's premises to see if you are using their spectrum. I'm no expert, so those of you out there who are please correct me if I misspeak here. Bluetooth operates in unlicensed spectrum and is mostly harmless because of it's low power. (Having to share that bandwidth with other devices is another chit on my side in the discussion above, but nevermind that). CDMA of any type, or any other wireless technology in use in any type of cell phone, uses licensed spectrum. Devices which use licensed spectrum must pass muster with the FCC. Even if a very low power CDMA device that you envision would work and probably not affect others, I don't think any company would make it because the FCC wouldn't approve it.

Maurice, I also thought Bluetooth had more than 750kbps. Even if it requires a lot of bandwidth, this is for local networking where the server or base station typically is no more than 50 meters away from the work station containing a computer or other device. Maybe the speed is faster in a fixed wireless local loop application. Art

Ah Maurice, You seem to be venturing into the area of Wireless Personal Area Networks (WPAN's)-- and further into BlueTooth2, which may very well use some form of Coded, or Wideband OFDM. Whether or not Qualcomm is even obliquely involved in this, is a question which should well be investigated , IMHO. I understand that Qualcomm is partnering with MSFT in a project or two, in Washington State, and Microsoft is certainly very heavily involved in an effort to get major industry players to standardize these types of systems or technology in the 5Ghz License Free, band. They fully intend to have some form of agreements , in order to standardize the necessary device drivers , etc prior to new Operating System releases. It seems very logical that Qualcomm should have a serious interest in these devices, in particular BlueTooth2 products. Do you have any insight on where Qualcomm may be going, in these areas ?
