Bluetooth piconet

Does anybody use Bluetooth at all?

Somebody must. Exploits are only written against popular protocols. Right?

Oh. Did you mean anybody HERE?

No. The local cellular provider shut down the Bluetooth on everyone's fancy phones unless they pay extra to get the feature enabled.

Actually, the carrier doesn't disable this feature. They do disable the one which allows the cellphone to synchronize its phone book with a PC, upload/download photos sent/received via the phone, etc.

There was a story in the WSJ a few months ago about a guy who bought a top of the line phone only to find that his carrier disables most of the bells and whistles (until a fee is paid). Even if the feature doesn't involve interaction with the carrier's network.

The Bluetooth headsets are nice, from what I've heard. Particularly if you have one of those combo phone-PDA gizmos. Try taking notes on the PDA while holding it up to your ear for a call. Now, try to drive and balance your latte too.

I see lots of people with the bluetooth headset (small percentage, but lots of people). They look like "first adopter" types who would be more than happy to pay extra for just about anything like that.

Of course one of the advantages of using a headset was to move the phone's transmitter away from one's head. Now making the headset wireless sorta defeats this advantage. The acceptable long term exposure limit (according to the FCC) to RF in the cellular/pcs bands ranges from 1mW to 5mW per square cm.

What's even nicer is having no cell phone, and no pda, and giving your latte your full attention. I'm a "never adopter."

I'd worry more about some people's heads acting as tuned cavities and disrupting the cellular signal.

There's still an advantage since the BT headset transmitter transmits MUCH less power than the handset does. So using the BT headset greatly reduces the amount of EM power impinging on your brain or other tender head parts.
