I know my wireless keyboard & mouse(mostly keyboard) messes up when my iphone is close by. Any other wireless devices in the general area?

I usually have an iPhone and iPad Mini retina nearby, I'm not sure if they're the problem though because I used to use the same mouse dongle and mouse with my laptop, which was always next to my iPhone also. I'll try it out again and let you know if it helps though, it can be a possibility.
