The sensitivity of typical wide band receivers is approx. -100 dBm while a narrow band receiver has better than -117 dBm sensitivity. A sensitivity difference of 17 dB is equivalent to approximately 50- hold in transmission power. The communication range of a 10 mW (10 dBm) transmitter with a receiver that has -117 dBm sensitivity is equivalent to the range of a 500 mW (27 dBm) transmitter with a -100 dBm sensitivity receiver.

The ITU (International Telecommunication Union) designates the class of emission according to the signal characteristics. The class of emission consists of 3 symbols. The 1st symbol is for the type of modulation of the main carrier, the 2nd symbol is for the nature of the signal(s) modulating the main carrier, and the 3rd symbol represents the type of information to be transmitted.

F1D means F = Frequency modulation, 1 = A single channel containing quantized or digital information without the use of a modulating sub-carrier, and D = Data transmission, telemetry, telecommand
