when I was at Intel, we used software/hardware to mitigate interference with bluetooth and WiFi, basically how it worked was the the WiFi radio would tell the bluetooth radio what freq it was on, then the BT radio would stay away from that channel.
It made a HUGE difference in both radios, the noise levels were minimal in comparison to "non-Intel" chipsets. I am unaware if anyone else did this in other laptops/devices (usually not) The problem starts to happen when you mix multiple vendors' radios together. http://www.intel.com/network/connectivity/products/wireless/prowireless_mobile.htm Performance With throughput up to 54 Mbps at 5 GHz (802.11a) and 2.4 GHz (802.11g), the Intel® PRO/Wireless network connection family enables fast network connections. The Intel® Wireless Coexistence System helps reduce interference with certain Bluetooth* devices.
