RMX Radio
The RMX radio transceiver is a two-way, 9,600 baud VHF/UHF radio modem. It's a short-range (up to 25 miles) line-of-site option, but can be used in combination with Globalstar satellite modems to provide satellite access to an RMX station cluster throughout North America. There are no airtime costs, but the radio spectrum used must be licensed by the FCC (requires a radio station license).

No airtime costs. Less expensive over time than digital cell or GlobalStar.
