Logitech V200 and G7 mice work on 2.4GHz. Lots of others are now on
2.4GHz. Search Google for "2.4GHz mouse". There are also Bluetooth
mice on 2.4GHz. Search Google for "Bluetooth Mouse".
Most 2.4GHz mice work like cordless phones. The FCC graciously allows
adaptive frequency selection to avoid interference. The mouse picks
one of 80 assorted 1MHz wide channels, sends data in short bursts, and
does not change channel. Interference is minimal. Unlike 802.11
FHSS, mice are not required to frequency hop over the entire band
(thus obliterating everything).
Keyboards and mice are not going to an interference problem because
they're not on the air long enough to cause a problem. That's not the
case if you use BlueGoof for file transfers and other apps that
generate lots of traffic.
I once tried to intentionally create interference with a 2.4GHz mouse.
I had the mouse doing continuous movements. No noticable drop in
thruput. However, I can literally kill a wi-fi file transfer with a
BlueGoof 1.1 adapter (which does not have Adaptive Frequency Hopping)
by simultaneously moving data. That's NOT the case with 2.0, which
will find an empty block of channels.
