Practical Guide: 5G Campus Network with RedCap – How Does It Work in Industry?Teltonika RUT276 Compact RedCap 5G Router with Industrial Serial (RS232/RS485, Modbus, OPC UA, BACnet), Optimized for Industrial Automation and Smart City
The Teltonika RUT276 is a compact 5G RedCap router specifically designed for industrial and smart city applications with classical legacy protocols. Featuring native RS232/RS485 interfaces via 6-pin terminal block, the RUT276 provides seamless integration opportunities for Modbus (RTU/TCP), OPC UA, BACnet, and DNP3 systems. The combination of modern 5G connectivity and industrial serial communication makes it ideal for utilities, water and gas operators, smart city controllers, and automation systems.
Industrial Serial and Legacy Protocols for Plug-and-Play Integration
The RUT276 offers dedicated RS232 and RS485 interfaces (6-pin terminal block) for direct connection to PLCs, energy meters, flow regulators, and other industrial devices. Full support for Modbus RTU/TCP, OPC UA, BACnet, and DNP3 (with DLMS/COSEM for utility meters) enables plug-and-play integration into existing industrial ecosystems without additional gateways or converters.
5G RedCap for Future-Ready Connectivity with Low Power Consumption
With 5G Sub-6 GHz SA architecture, the RUT276 delivers up to 223 Mbps download and 123 Mbps upload (3GPP Release 17 RedCap) at significantly lower power consumption and cost than full-band 5G. Automatic fallback to 4G LTE Cat 4 (195 Mbps DL / 105 Mbps UL) guarantees connectivity even in transition zones or areas with incomplete 5G coverage.
Flexible Power Supply: 9–57 VDC + Active/Passive PoE
The RUT276 can be powered via 2-pin industrial DC power connector with 9–57 VDC, Active PoE (802.3af, 12.94 W) on LAN port, or Passive PoE (16–57 VDC via spare pairs 4,5/7,8). This extreme flexibility reduces installation effort and costs in distributed networks and solar-powered systems. Power consumption: idle under 2 W, maximum under 3.5 W.
Dual-SIM with Auto-Failover for Network Redundancy
The RUT276 supports dual-SIM (2FF Mini-SIM, double-stacked SIM tray) with automatic failover switching on network outages, weak signals, or data limit breaches. This ensures network continuity in critical smart city and utility scenarios. Also configurable with eSIM option.
Compact, Robust, and Versatile
With dimensions of 83 x 25 x 83 mm and 132 g, the RUT276 is ultra-compact for switchgear cabinets, utility poles, and outdoor installations. IP30 rating, aluminum enclosure, and operating range from -40 °C to +75 °C with 90% humidity tolerance. DIN-rail mount, wall mount, or flat-surface mounting. Micro SD-card slot for extended storage (up to 2 TB).
Wireless and Wired: Wi-Fi 4 and 2x Ethernet
The RUT276 features Wi-Fi 4 (802.11b/g/n, 2.4 GHz) supporting up to 50 simultaneous devices, fast roaming (802.11r), and mesh support (802.11s). Two 10/100 Mbps Ethernet ports (WAN/LAN) with VRRP, load balancing, and multi-WAN failover provide additional redundancy options. Passive PoE out possible on LAN port.
Enterprise-Grade Security and Remote Management
RutOS (OpenWrt-based) features firewall, DDoS mitigation, WPA2-Enterprise/WPA3 support, and comprehensive VPN options (OpenVPN, IPsec, WireGuard, L2TP, DMVPN, EoIP). Teltonika RMS enables centralized remote configuration, diagnostics, firmware updates, and secure VPN hub creation. API and CLI access for advanced automation and integration with SCADA systems.
