Wireless Operation

Wireless Operation

Radio remote controls allow electrical devices and installations to be operated wirelessly from the near vicinity. Control is exercised through wireless signals in which a quartz oscillator prescribes the channel for transmitter and receiver. So that common frequencies do not overlap in a limited frequency range, frequency ranges are allocated by means of channel spacing. Public frequency ranges can be used in Germany without reporting or paying a fee. Radio remote controls and receivers are used for the remote control of garage doors or awnings, for instance.
