[Bug 219057] Re: Bluetooth does not coexist with WiFi

[nathan]

This is an issue that will exist until the specifications of Bluetooth
and Wifi become more collaperative. Unfortuntely, Bluetooth and Wifi
both run on the ISM band (2.4 to 2.4835 GHz). When Wifi encounters
interferance, it simply tries to resend the packet. This causes Wifi to
slow to a halt as it will continue to try to resent the packet until it
is successful easily cutting Wifi speeds in half or usually much more
than half. When Bluetooth encounters interferance, it jumps onto another
frequency and tries sending the packet again (it would perform the jump
whether or not interferance was discovered on that particular frequency
as it's part of the Bluetooth spec to preform frequency "hopping"). Due
to the fact that this frequency "hopping" occurs at a hardware level and
not software, you cannot force bluetooth to use or to not use certain
channels. Unfortunately, this is hardware dependant to my knowledge.
