A system that is able to transmit data from one point to another without a direct connection, i.e. wires. Typically such systems use some form of RF (Radio Frequency) transmission, which involves modulating the signal with a transmitter and subsequently demodulating it at a receiver tuned to a common frequency. In some situations referring to such systems as wireless can be a bit of a misnomer. For example, in a typical guitar wireless system there are actually two wires where normally only one is required. The cable that would run between a guitar and amp is replaced by a wire from the guitar to a radio transmitter and then another wire from the receiver to the amp. Nevertheless the convenience provided by wireless systems is well known and as technology continues to improve they will likely be used more, and in more creative ways.
