Infrared wireless microphone systems are the best solution for classrooms. In today's RF saturated world a regular (VHF or UHF) microphone system risks interference from a variety of other devices and sources. Cell phones, radios, TV, PA systems, police and emergency service systems, etc., can all interfere with VHF and UHF, but not with IR. Furthermore, infrared is perfect for classroom audio. IR is short-range and cannot penetrate walls. Hence, a school can have as many classrooms as desired with individual audio systems, without causing any interference. In addition, since each classroom system is set with same channel, teachers can go from room to room without the need to change microphones.
