  • Page 25: Transmission Range

    Transmission range 4 Transmission range General information about wireless transmission Wireless signals are electromagnetic waves whose strength becomes weaker on their path from the transmitter to the receiver (this is referred to as path attenuation). The field strength reduces at an in- verse proportion to the square of the distance between the transmitter and receiver.

  • Page 26: Possible Impairment Of Wireless Transmission

    4 Transmission range Possible impairment of wireless transmission Collisions when using too many transmitters When using a large number of transmitters, do not select a transmission interval which is too low, other- wise the radio channel will be unnecessarily occupied. A transmission interval that is too low leads to a very high data volume on the selected radio frequency, which can lead to collisions with other transmit- ters.
  • Page 27 4 Transmission range For this reason, we recommend using a maximum of 16 transmitters for a transmission interval of 1 s. Selecting a larger transmission interval allows for a significantly larger number of transmitters. 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.
