The wireless mouse frequency is mostly 27MHz or 2.4GHz , but 315MHz or 433MHz is seldom used ,can someone tell me the reason ? Thanks !
 

Interference from other devices ?
Door openers ?
 

Re: A question about wireless mouse frequency, someone help

Thanks! but i wonder if the interference is the main cause to reject 315MHz solution ? is there other reasons ?
 

Re: A question about wireless mouse frequency, someone help

I would think interference is the main reason....
Otherwise the other thing I could think of is the design of the antenna in the wireless systems...But then 2.4 GHz freq and higher would be preferable..
