Wireless routers transmit in the 2.4Ghz range this is the same as video senders and digital cordless phones. I have heard of people complaining that these interfere with each other. (tho mine have never been a problem) I believe that some wireless speakers do transmit in this frequency so it is a potential problem. I have also seen ones that transmit in a lower frequency band (863Mhz I think) so with these there should be no problem. You will have to check all the specs.
