Study Shows Bluetooth, 802.11b Don't Interfere
There has been some concern that, because Bluetooth and 802.11b use the same unlicensed, 83 MHz wide, 2.4 GHz radio frequency band, the two wireless standards would interfere with each other when used together. Prelimary results from a recent study show that this doesn't happen. The range of each was unaffected by the other. The study doesn't seem to have looked at whether connection speed was affected.
The study was carried out by the Pennsylvania State University's Applied Research Laboratory and Wireless Infotech Education Services. Both groups agree that additional tests with varying procedures are necessary to completely determine the likelihood of Bluetooth and 802.11b interference under all circumstances.
In this study, conducted in a large manufacturing facility, the determined 802.11b range was approximately 284 feet with or without the presence of Bluetooth. Likewise, the Bluetooth network range was 64 feet regardless of whether the 802.11b device was active.
About 802.11b
The 802.11b standard is used to create a wireless, Local Area Network (LAN) and allows connections across ranges as great as 100 meters, depending
on power level. Connections are made via access points and consequently multiple devices can be connected to the network through an access point,
provided they are within range. An access point functions as the interface between the wired network and wireless network.
About Bluetooth
Bluetooth is a low-powered, short-range wireless network technology best suited for mobile devices, as they may not have enough power to support 802.11b signals. It creates a Personal Area Network (PAN) by directly connecting two devices together within a range of approximately 10 to 100 meters depending on power levels. It is also being used as a networking option for mobile devices.

c_blue: Yo trabajaba para el regulador de Venezuela (el "equivalente de la FCC" en USA, como lo llamas), y dado que por lo visto se desarrollarán gran cantidad de aplicaciones del tipo "sin licencia" en la banda de 2.4 GHz, tuvimos que reevaluar los planes para esa banda. No estaría de más que te dirigieras al regulador de tu país para plantear esta situación.
Sorry folks, this will be in spanish!

FALSE
but the bandwith is drastically reduced (from 11 to 2 Mb) ... bluetooth software and hardware makers are working on workaround.
RE: TRUE
And what sort of workaround do you envisage? They can't modify the basics of BT operation (ie frequency, hop rates etc). I think the 802.11 guys need to make their system more robust as more and more BT devices come into the market.

RE: FALSE
Dosen't anybody think 1/5 the bandwidth is important?
I definately consider that 'interference'.
BT is pretty much a waste of time, anyways.

This is really great news...

The skinny
Look, BT and 802.11 are working together and have since forming the BT SIG group. They do different things within the same air space.
For some time now a few people have been sharing a vision where both 802.11 and bluetooth work together. What will the future hold?
