Description
The 4RF Aprisa SR+ APQQ-N450-SSC-HD-40-ENAA is a high-capacity, licensed narrowband point-to-multipoint digital radio engineered for mission-critical SCADA, telemetry, and industrial automation applications. Operating in the 450-520 MHz UHF band (ETSI compliant), this half-duplex model delivers secure, reliable wireless connectivity in challenging environments where spectrum efficiency, long range, high data integrity, and robust cybersecurity are essential.
Key features include:
- Licensed UHF Operation: 450-520 MHz band with software-selectable channel sizes (12.5 kHz, 25 kHz, 50 kHz) for regulatory compliance and optimal spectrum use.
- Connectivity: 4 Ethernet ports (10/100Base-T) for IP-based SCADA networks, supporting advanced L2/L3 routing, VLAN tagging, QoS, and firewall filtering.
- High Capacity & Efficiency: Gross data rates up to 120 kbit/s in 25 kHz channels (with 64QAM modulation), adaptive coding and modulation (QPSK to 64QAM), advanced forward error correction, and header/payload compression for maximum throughput in narrowband channels.
- Security: Defense-in-depth approach with AES-256 encryption, authentication, address filtering, and user access control (including RADIUS support) to protect against cyber threats.
- Networking Flexibility: Configurable as base station, remote station, repeater, or base-repeater; supports point-to-point, point-to-multipoint, and complex topologies with low latency and high reliability.
- Industrial Durability: Rugged design with wide operating temperature range (-40°C to +70°C), optional Class I Div 2 hazardous location certification, and proven performance in harsh utility/oil & gas environments.
- Management & Integration: Easy-to-use web GUI, SNMP support, over-the-air management, and seamless integration with legacy serial/IP SCADA protocols (transparent bridging/routing).
- Applications: Electricity grid distribution automation, smart grid concentrator backhaul, oil & gas production metering/pump control, water/wastewater flow monitoring, renewables (wind/hydro), and pipeline telemetry.
Manufactured by 4RF (now part of Aviat Networks), the Aprisa SR+ series is trusted worldwide for its robustness, future-proof design, and long-term support in licensed narrowband networks.
