Abstract
A communication system for safe wireless control of an maneuverable object. A control unit includes an operator for operating the object and a receiver for receiving wireless information. A portable operating unit has a transmitter for transmitting wireless information. The information is divided in time slots, each including a data package. The receiver includes a detector for detecting in a time part of a time slot the presence of the data package and a calculator for calculating upon a reception failure the number of time parts having no presence of the data package following a time slot with presence of the data package. The control unit exercises a control command when a data package with a correct information has been received within a number of time parts just exceeding a full time slot.
