Bluetooth uses 79 channels in the 2.400-2.4835 GHz range with 1 MHz channel spacing. It uses GFSK with a symbol rate of 1 Ms/s.

The possible problems with 802.11 is that BT uses frequency hopping with 1600 hops/s thus giving higher probability that BT frames will interfere with 802.11 frames than the other way around.
