#CMT# #/CMT# The transmitter (1) is designed in such a manner that a period of validity (V1, V2) is assigned to sent signals in transmit mode, where the signal is valid for a given mobile receiver (3) within the period of validity of the respective signal as spatial coordinate information. The spatial coordinate information for the part of the signals includes a frequency polygon, which describes the limit of the period of validity, where a sequence of the corner coordinates of the frequency polygon are sent as the spatial coordinate information. #CMT# : #/CMT# Independent claims are also included for the following: (1) a control system with a transmitter (2) a method for wirelessly sending signals by a transmitter (3) a method for receiving and processing signals sent by a receiver. #CMT#USE : #/CMT# Transmitter for wirelessly sending signals in a mobile communication frequency band and/or in a radio frequency band to a mobile receiver in a control system e.g. traffic control system such as traffic light signaling system (all claimed). #CMT#ADVANTAGE : #/CMT# The transmitter sends variable arbitrary validity periods in the form of spatial coordinates to the receiver where the information is evaluated, thus conveying the period of validity directly in the form of spatial coordinates to the receiver, and hence eliminating the need for special electronic cards. The transmitter enables relatively large freedom during positioning of the transmitter, and dynamically changing the periods of validity. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of communication between a transmitter and a receiver.
