Bluetooth is a lower bandwidth, shorter ranger version of 802.11b. However because of these trade offs it is is very low power solution which can be embedded in hardware devices. This means that finally your palm pilot can talk to your cellphone which can talk wirelessly (using the radio waves) to a computer, digital camera, another cellphone or other devices. As best as I can tell it is what IrDA should have been all along.
GPRS and UMTS phones generally includes a bluetooth port.
We are working on a BlueToothFaq and collecting BlueToothLinks. If one of your questions isn't answered their please add the question and hopefully someone will notice and answer it. Otherwise you are of course welcome to post to the MailingList with any wireless questions you may have.
Say, I just noticed that NigelBallard of Celeric joined the mailing list. Nigel is a Bluetooth Guru! Hi Nigel! Feel free to write your comments on this page using the nifty WikiWiki editor. This is my first real experience with Wiki. Still learning to edit.
I'm still a network dummy but I'm having fun. When do we drink beer again?
