4RF Australia provides licensed, sub 3 GHz radio communications equipment for critical infrastructure applications. The Aprisa SR family of smart point-to-multipoint radios, available in VHF and UHF frequency bands, provides secure communications for telemetry and SCADA applications. Both radios support serial and Ethernet traffic for a future-proof approach when migrating from serial to IP. The Aprisa SR offers up to 19.2 kbit/s capacity and the Aprisa SR+ provides up to 120 kbit/s capacity for more data intensive applications. Both products provide industry-leading security, reliability and incorporate unique traffic management techniques for maximum efficiency and performance in the real world. The Aprisa XE point-to-point microwave link, available in ten frequency bands between 300 MHz and 2.7 GHz, provides long distance, carrier-class communications for challenging applications such as offshore linking or long distance pipeline monitoring.
