Abstract: The invention relates to a radio ripple control system for the control of a plurality of decentralized customer terminals in dependence on customer-initiated transmission requests by means of central longwave transmission devices, comprising at least two central longwave transmitters operable independently of one another, at least two central units which are each associated with one of the longwave transmitters and which are designed in each case for the control of the transmission operation of at least one longwave transmitter in dependence on the customer-initiated transmission requests, a plurality of decentralized customer stations designed for the transmission of the customer-initiated transmission requests to the central units, and a plurality of decentralized radio receivers stationed in the reception region, with at least one customer terminal to be controlled being associated with each of the decentralized radio receivers, each of which is associated with at least one of the central unit in dependenc
