Industrial LTE Router Teltonika RUT261
The Teltonika RUT261 router is a compact, cost-effective solution for stable connectivity over mobile networks. With support for 4G LTE Cat 6, it delivers data speeds of up to 300 Mbps (download) / 50 Mbps (upload), ensuring smooth data transmission even for more demanding operational needs in industrial automation, smart city and IoT sectors.
Thanks to its compact dimensions (83 × 25 × 74 mm), it fits easily into space-constrained areas such as small control cabinets, vending machines and charging stations.

Connectivity options
It offers flexible connectivity with two 10/100 Mbps Ethernet ports (1× WAN, 1× LAN), Wi-Fi 4 (802.11b/g/n), and full support for eSIM or a traditional SIM card.
Design and durability
Its compact, durable design, robust aluminium housing and IP30 rating enable reliable operation in demanding conditions at temperatures from -40 °C to +75 °C.
Security and communication
Industrial protocols and security features include extensive support for communication protocols such as MQTT, Modbus TCP and OPC UA, as well as advanced security standards including OpenVPN, IPsec and a firewall.
Tip for outdoor installation without signal loss
For using the router in demanding outdoor conditions (e.g. with CCTV systems, motorhomes, boats or remote technical sites), we recommend purchasing the integrated omnidirectional antenna QuWireless QuSpot A240S.
This set serves as a robust, waterproof IP68-rated enclosure into which the Teltonika router can be easily installed.
The Teltonika BAT120 backup power supply is available for the RUT261 router. In the event of a power outage, it takes over powering the router for up to 6 hours.
Secure RutOS operating system
The RUT261 router runs RutOS, a secure operating system based on Linux (OpenWrt). This is a key advantage when choosing Teltonika routers. The system provides advanced security features, encryption, VPN support and full compatibility with the Teltonika RMS remote management cloud platform.
Remote monitoring and management
RMS remote management provides full support for the Teltonika Remote Management System, enabling efficient monitoring, VPN configuration and bulk device management without the need for an on-site visit.
