Bluetooth and 802.11: A Tale of Two Technologies

This article from serves as a good explanation about BT and 802.11, their differences and similarities:

Wireless networking is on track, literally. The two hottest technologies ? Bluetooth for products and 802.11b for Wireless Local Area Networks (WLANs) ? currently share the same “space”: the unregulated 2.4 GHz radio band, the frequency most well known as the pathway for our microwave ovens.

As these technologies emerge as common-day solutions, concern has increased over the potential for frequency interference. It could be that Bluetooth activity will do the jamming. Bluetooth “hops” faster through the spectrum than 802.11. That rapid-fire barrage ? which gives Bluetooth its device-driving bite ? could, however, affect the performance of an 802.11 network.

An article at Wired may also shed some light on Bluetooth. The print version had a nice illustration, but I don’t see it here.
