Freewave has a line of 900 MHz and 2.4 GHz spread-spectrum radios for wireless data communications. These radios do not require licensing and have a throughput of 115.2 KBaud at up to 20 miles range (with unity gain antenna). Longer transmission ranges can be achieved with higher gain antennas and/or repeaters.

Meteor designs low frequency radios for remote data communications, locational information, and other wireless information needs. The MMC-545B Packet Data Radio is a wireless, intelligent radio that reliably links users with their data. From line-of-sight distances up to 1,000 miles, the MCC-545B offers both message and data communications for a wide variety of applications. The MMC-545C RF Modem is similar to the MMC-545B, but can also operate as a base station, repeater or mobile unit. Both radios can operate in Extended Line of Site (ELOS) Mode or Meteor Burst communication mode.
