4RF is a world class designer and manufacturer of high efficiency narrowband radios for critical infrastructure applications. 4RF SCADA radios operate in VHF, UHF and 900 MHz licensed bands and the Point-to-Point radios provide a wider range of sub 3GHz frequencies.

The Aprisa SR family provides narrow band point-to-multipoint radio communications, designed and optimised for SCADA and telemetry applications. The Aprisa SR provides up to 19.2 kbit/s capacity for everyday applications, with two Ethernet ports and one serial port. The Aprisa SR+ provides industry leading capacity of up to 120 kbit/s for more data-intensive applications, with four build-configurable ports for advanced flexibility.

 Aprisa SR benefits

  • 360 degree security protection, including AES 256 encryption, data authentication and micro-firewall
  • Easy configuration and management, with laptop-free install and over the air software upgrades
  • Standards-based with SNMP for integration with network management systems
  • Reliable and robust for real world utility applications, and easily integrated with current SCADA infrastructure
  • Advanced, efficient channel access and traffic management, optimised for SCADA applications

Aprisa SR applications

There are applications for the Aprisa SR throughout electricity, water and oil and gas communications:
