1. SMART, SECURE POINT-TO-MULTIPOINT RADIO 220 MHz, UHF and 900 MHz licensed bands Datasheet FCC and IC licensed bands Smart, secure, industry-leading speed licensed point-to-multipoint SCADA communications for industrial monitoring and control for the electricity, water, oil and gas industries • High capacity: to meet the growing number of data-intensive applications in the SCADA environment, the Aprisa SR+ provides data rates of up to 216 kbit/s in 50 kHz licensed channels. • 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 multiple serial and Ethernet 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. • Adaptable: the Aprisa SR+ integrates into a range of network topologies, with each unit configurable as a base 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. • Link efficiency: Adaptive Coding 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. • Reliable and robust: the Aprisa SR+ requires no manual component tuning and maintains its high power output and performance over a wide temperature range. • 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. The Aprisa SR+ in brief • 220 MHz, UHF and 900 MHz licensed bands • RS-232 and IEEE 802.3 protocols with multiple port options • Software selectable 12.5 kHz, 25 kHz and 50 kHz channel sizes • Full and half duplex operation • Single or dual frequency • Gross data rates greater than 200 kbit/s • 256, 192 or 128 bit AES encryption • Adaptive coding modulation: QPSK to 64 QAM • Advanced forward error correction • Software selectable dual / single antenna port operation • Transparent to all common SCADA protocols • Dedicated alarm port • Protected station option • –40 to +70 °C operational temperature • 210 mm (W) x 130 mm (D) x 41.5 mm (H) • FCC and IC standards compliant • Seamlessly integrates with Aprisa XE point-to-point radio Aprisa SR+ applications Applications throughout the electricity grid and renewable energy: • Smart grid: concentrator communications and GPRS replacement • AMI / AMR: high density data concentrator backhaul • Renewables: wind farm, tidal, hydro automation • Measurement, control and protection in MV / HV distribution / transmission • Co-generation and community energy storage monitoring and control in distributed storage and generation • Fibre substitution in substation and feeder automation upgrades
