Freewave IO Radio

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.

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.

FGR2-IO Series radios operate in the unlicensed 900 MHz spectrum and are available as a standalone board-level or enclosed device, as well as an expandable format to meet any wireless IO needs. All models can operate in one of two modes: Wire Replacement or Modbus. For wireless replacement mode, FGR2-IOS and FGR2-IOE can operate as a slave connected to an FGRIO-M master. In Modbus mode, all radios can be directly connected as an IO peripheral to a SCADA network. FGR2-IO Series radios can operate up to 60 miles with clear line of sight with the ability to extend through Endpoint/Repeater while the Modbus Gateway can be any FGR Series radio. The FGR2-IO Series radios offer error free communication utilizing 32-bit Cyclic Redundancy Check (CRC) with automatic retransmissions. They are Class I, Division 2 certified for operating in the temperature range of -40 degrees Celsius to 75 degrees Celsius and are ideal for solar power applications.
