Thank you

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
