Some Audience Response Systems utilize RF to transmit student choices, votes or answers from the Clickers to the base station (transceivers). These clicker remote controls do not need to be line-of-sight to the receiver to be able to work. Thus the receiver does not need to be permanently mounted on walls of the classroom thus students do not need to aim their clickers at a receiver to have it register their response. This allows the receiver to be very portable for use in numerous rooms. RF does penetrate walls and but the systems are designed so that they will not interfere with other devices in adjoining rooms. Normally RF systems can handle up to 1000 clickers per receiver. Thus they are ideal for large class sizes.
