4RF Aprisa SRi unlicensed radio

The 4RF Aprisa SRi utility-grade unlicensed SCADA radio is designed to deliver resilience and security for tough critical infrastructure requirements and is suitable for edge-of-network extensions or for where those circumstances dictate that an unlicensed product is a good fit.

Based on Aprisa SR family technology, the SRi is a licence-free 915–928 MHz ACMA/RSM AS/NZ4268 radio that uses technology such as time-sliced fast hopping, forward error correction and ARQ to combat interference and better utilise those prime channels in noisy environments. Combined with QAM modulation, this product can deliver speed and reliability in today’s busy networks. The Aprisa SRi is suitable for both point-to-point and point-to-multi-point operations. A fully monitored hot standby configuration is available for critical sites.
