Aprisa SR
Industrial Wireless Router
VHF and UHF Bands - Point to Multi-Point
smart, secure, point-to-multipoint SCADA communications for oil, gas, and utility monitoring and control
The Aprisa SR and Aprisa SR+ are distance-engineered and optimized for SCADA and telemetry applications, providing reliable, robust performance however demanding the conditions: what we call ‘real world radio’. RF performance is unbeatable, with attention paid to every element of the design: transmitter, receiver, modulation, and efficiency. The receiver maintains exceptional low noise operation via excellent sensitivity for greater distance and high selectivity and intermodulation suppression for superior protection from interference. This performance is complemented by fast switching circuitry and high transmit power ensuring long-distance operation with exceptional system reliability and availability.
Key Features
- Secure: with its defense-in-depth approach, including AES encryption, authentication, address filtering, and user access control, the Aprisa SR protects against vulnerabilities and malicious attacks.
- Future-proof: the Aprisa SR supports serial, Ethernet, and IP interfaces in a single, compact form factor, and is standards-based for long term incorporation into SCADA networks while protecting the legacy
investment in serial devices. - Advanced L2/L3 capabilities: selectable L2 Bridge or L3 Router modes, with VLAN, QoS, and filtering attributes to support narrow bandwidth channels and mission-critical traffic while meeting increasing security and IP network policy requirements.
- Efficient: the ability to configure detailed radio parameters means that network performance and efficiency can be optimized for the exact network topology, however complex.
- Flexible: the Aprisa SR integrates into a range of network topologies, with each unit configurable as a base station, repeater, or remote unit.
- Easily managed: an easy-to-use GUI supports local element management via HTTPS and remote element management over the air, and SNMP support allows network-wide monitoring and control via a third-party network management system.
- Reliable and robust: the Aprisa SR requires no manual component tuning and maintains its high power output and performance over a wide temperature range.
