Multiple Wireless Mice/Keyboards Interfering

My office is in the process of upgrading everyone to newer computers including wireless mouse and keyboard combos. It seems that when my co-worker in the cubicle across from mine is using her mouse, my mouse moves irratically. The mouse and keyboard work fine otherwise. To fix this, I tried placing the reciever-hub underneath my desk, and while it solved the mouse problem, the keyboard became more difficult to use (it wouldn't pick up on all of the keys that I was typing). Is there any way to change a setting (similar to switching to a different channel on a walkie-talkie) so that multiple wireless mouse/keyboard combos can work in close proximity?
