wireless key board ?

Hi,

I would like to know how the wireless key board and mouse are connected to a PC. Which frequency they are using. Can anybody suggest any link where I can get design details of these devices.

Thank you
Itp
 

i'm not shure, but
currently using frequency is 27Mhz and use usb port. in that frequency is happened some confusions like - with one keyboard write on two computers and interferences with other radio-based devices
i readed, don't see it
recently i read that cypress offers new wireless USB chip for keyboards, mice.
it work at 2.4 GHz
the name is CY694X go to www.cypress.com and see
that's all from me
