Introduction to SATEL radio modems

A radio modem transmits data several kilometers over a wireless connection to another radio modem over a point-to-point or -multipoint link. Radio modems are independent of mobile and satellite network operators and no cost is thus associated with transferring data. Private radio modem networks can use either unlicensed (e.g. ISM) or licensed frequency bands (UHF, VHF).
