What is a radio modem?

A radio modems transmits data wirelessly over a point-to-point or point-to-multipoint link. Radio modem based data transfer is usually  used in mission-critical applications where reliability and latency of the data transfer are essential to the operation of the system. Radio modem network is independent of mobile and satellite network operators and no cost is associated with data transfer. Private radio modem networks can use either unlicenced (e.g. ISM) or licenced frequency bands (UHF, VHF).

Range up to 100 km

The operation range  varies depending on the transmission power, antenna gain and mast height and environment. In rural areas a 1 W radio modem with a line-of-sight radio link may range over 20 km and even up to 50 km in ideal environments. In dense metropolitan areas, a corresponding range may vary from several kilometres to over 10 km. With a 35 W radio modem, a range of up to 100 km can be reached. By using a radio modem as a repeater station, much broader areas can be covered.
