Freewave FGR3

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.

FGR3 Series 900 MHz Industrial radios are the next generation of the FGR2 Series radios. They are backward compatible with the FGR2, FGR and DGR Series of Freewave serial radios, allowing for a smooth transition from serial to Ethernet communications without replacing existing wireless data communication infrastructure. They are offered as a board-level product and in a ruggedized enclosure. They feature a combination of serial and switched Ethernet ports and can operate as a gateway, repeater or endpoint and also, as a simultaneous repeater and endpoint. The FGR3 Series radios offer error free communication utilizing 32-bit Cyclic Redundancy Check (CRC) with automatic retransmissions. They can operate up to 60 miles with clear line of site and have the ability to extend that distance through repeaters. Secure 128-bit and 256-bit encryption options are available. The FGR3 Series radios are Class I, Division 2 certified for operating in the temperature range of -40 degrees Celsius to 75 degrees Celsius. They are low power consuming, making them ideal for battery, solar and DC applications.
