    SATELLINE-M3-TR1/ SATELLINE-M3-TR1 869 User Guide, Version 5.5 14.2 Considerations Even though the radio modem module is designed to withstand interference beyond type approval requirements, some level of interference is inevitable when a small radio modem module is integrated closely to modern high speed electronics. The following issues should be considered in order to make a working integrated solution.

  • Page 89 SATELLINE-M3-TR1/ SATELLINE-M3-TR1 869 User Guide, Version 5.5 weather tolerance of the materials used must also be taken into account. Installed materials must withstand all foreseeable weather conditions (frost, excess sun, direct UV-radiation, seawater etc.). Also possible environmental pollution must be considered (acids, ozone etc.).

    The transmitter power of the SATELLINE-M3-TR1 is 1 W (maximum) and the sensitivity of the receiver better than -115 dBm. Thus in a flat area and in free space with a 1/4 wave antenna (antenna amplification 1dBi) and antenna height of 1 m communication distances of 3 to 4 km can be achieved.

  • Page 93: Radio Field Strength

    SATELLINE-M3-TR1/ SATELLINE-M3-TR1 869 User Guide, Version 5.5 15.2 Radio field strength Radio signal strength must be good enough for successful data transfer. Where field strength is above a certain level, the operational results are very good. Below this level, a few dB marginal areas occur in which errors begin to be generated by noise and interference that will eventually lead to loss of connection.
