Zuki,
Check out the frequencies of most wireless mics and the vast majority are usually 900mhz or higher. This would not be a problem. 900mhz was selected several years ago because it has a very short range and extremely clean signal quality, plus very little chance of outside interference.
Good Luck,
Gary
