| area associated with a terrestrial transmitting station for a given radiocommunication service, within which a receiving station must be located for radiocommunication of a specified nature to be established under specified technical conditions
Note 1 – Several coverage areas may be associated with the same station.
Note 2 – The technical conditions include, inter alia, the following: frequency, characteristics of the equipment used both at the transmitting and receiving stations, how it is installed, quality of transmission desired, e.g. protection ratios, and operating conditions.
Note 3 – The following may be distinguishable:
– the coverage area in the absence of RF interference, i.e. that limited solely by natural or artificial noise;
– the nominal coverage area which is defined, when establishing a frequency plan by taking into account the foreseen transmitters;
– the actual coverage area, i.e., with allowance made for the noise and interference which exist in practice.
