Freewave Radios

Frequency-hopping spread spectrum (FHSS) is wireless technology that transmits radio signals by rapidly changing the carrier frequency among many distinct frequencies in a large spectral band. The frequency band is divided into sub-bands and signals “hop” their carrier frequencies among the sub-bands in a predetermined order. The “hopping” frequencies are difficult to intercept and interference at a specific frequency will only last a short time.
Freewave radios are designed for seamless integration into networks that require reliable link performance and support low power, long range machine-to-machine communications. Freewave radios transfer data in noisy, challenging environments covering over 60+ mile distances. By utilizing Frequency Hopping Spread Spectrum (FHSS) technology, Freewave provides an alternative to expensive Wi-Fi bandwidth, cellular or fiber.
Freewave FGR2 radios are only available for customers outside the US and Canada. The FGR2 series has been replaced by the FGR3 series.
Freewave FGR3 radios are backwards compatible with the FGR2 series and function as a repeater, gateway, endpoint or simultaneous repeater and endpoint in a single radio. The FGR3 radios are long range (up to 60 miles), secure (use FHSS), low power consuming and industrial grade (-40C to 75C).
Freewave IO radios can operate in either Modbus mode or Wire Replacement mode and are available as an enclosed device, board-level or expandable format. Modbus mode allows all radios to be directly connected as an IO peripheral to a SCADA network. For Wire Replacement mode, FGR2-IOE and FGR2-IOS can operate as slave connected to an FGRIO-M master.
