  • Page 17: Transmission Range

    Transmission range 4 Transmission range General information about wireless transmission Wireless signals are electromagnetic waves, the signal of which weakens during travel from the trans- mitter to the receiver (this is referred to as path attenuation). The field strength drops inversely propor- tionally to the square of the distance between the transmitter and receiver.

  • Page 18: Possible Impairment Of Radio Transmission

    4 Transmission range Possible impairment of radio transmission Collisions in case of too many transmitters When using a large number of transmitters, do not select a transmission interval that is too low, otherwise the radio channel will be unnecessarily occupied. A transmission interval that is too low leads to a very high data volume on the selected frequency, which can lead to collisions with other transmitters.
  • Page 19 4 Transmission range For this reason, we recommend using a maximum of 16 transmitters for the smallest transmission inter- val of 1 s. For the factory setting of 15 s, a considerably larger number of transmitters can be used. Estimating the maximum number of transmitters If more than the recommended 16 transmitters are to be used with a transmission interval of 1 s, select a higher transmission interval to prevent an increased error quota.
