4RF APRISA SR+ Industrial Licensed Wireless Telemetry Router
Smart, secure, industry-leading speed licensed point-to-multipoint SCADA communications for industrial monitoring and control for the electricity, water, oil, and gas industries – now with 256 QAM.
Supporting UHF, VHF and 900MAS licensed frequencies.
The Aprisa SR+ was 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
- High capacity: to meet the growing number of data-intensive applications in the SCADA environment, the Aprisa SR+ provides data rates of up to 576 kbit/s half duplex / 1,152 kbit/s full duplex in 100 kHz licensed channels.
- Secure: with its defense in depth approach, including AES encryption, authentication, address filtering and user access control including RADIUS, the Aprisa SR+ protects against vulnerabilities and malicious attacks.
- Future-proof: the Aprisa SR+ supports dual serial and dual Ethernet ports in a single, compact form factor, designed to cryptographically secure legacy serial, protect existing device investment, and enable new applications. Old and new application protocols can be run side by side.
- Advanced L2 / L3 capabilities: selectable L2 bridge, L3 router, or advanced gateway router combination L2/L3 modes with VLAN, QoS, NAT, and filtering attributes to maximize capacity in constrained bandwidth and prioritize mission-critical traffic while meeting tough security and IP network policy imperatives.
- Adaptable: the Aprisa SR+ integrates into a range of network topologies, with each unit configurable as a master station, repeater, or remote station; connect multiple RTUs / PLCs to a single radio.
- Flexible interfaces: the data interfaces can be configured for serial or Ethernet operation; a range of options are supported, including two serial and two Ethernet, one serial and three Ethernet, or four Ethernet ports. Support for NMEA GPS receiver option.
- Link efficiency: Adaptive Coding and Modulation (ACM) and forward error correction maintains the integrity of the wireless connection while an effective channel access scheme and IP routing ensures efficient transfer of data across the Aprisa SR+ network. Automatic Transmit Power Control maintains the minimum transmit power required for effective communications enhancing both frequency reuse and power savings. Advanced payload and Ethernet / IP / TCP / UDP header compression.
- Reliable and robust: the Aprisa SR+ requires no manual component tuning and maintains its performance over a wide temperature range using full specification industrially rated components and shared Aprisa family heritage.
- 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 variety of supported third-party network management systems.
