Teltonika TRB247 Cat1 BIS IoT Gateway

Teltonika TRB247

The Teltonika TRB247 stands out as a robust industrial-grade IoT gateway, designed to connect legacy equipment and sensors with modern data-driven infrastructure — even in remote or harsh environments.

By combining LTE Cat 1 bis cellular connectivity with serial, I/O and Ethernet interfaces, it offers a flexible, future-proof bridge between older industrial systems and cloud/SCADA or IoT platforms.

What is LTE Cat 1 bis — and Why It Matters

LTE Cat 1 bis (sometimes written Cat 1 bis) is a 4G standard optimised for IoT and M2M applications. Compared with older cellular standards, Cat 1 bis uses a single antenna instead of two. This reduces hardware complexity and footprint, while still delivering adequate data rates — typically up to 10 Mbps downlink and 5 Mbps uplink. It offers lower latency and higher throughput than NB-IoT or LTE-M, while remaining widely supported across existing LTE networks.

The result is a balance of reliable connectivity, moderate data throughput and broad network compatibility.  Ideal for remote sensors, telemetry, metering, asset tracking or any IoT use case where stable data and good coverage matter more than ultra-high speeds.

For devices like the TRB247, this means you get a single-SKU cellular solution that works wherever LTE is available — no need for dual-antenna setups or complex hardware, just dependable connectivity that scales with your deployment.

Why TRB247 Works in Real-World Installations

The TRB247 pairs Cat 1 bis cellular connectivity with a rich set of I/O, serial and network interfaces — making it ideal for integrating legacy industrial devices (meters, pumps, sensors, controllers) into modern networks or cloud platforms. Its rugged aluminium housing, wide temperature tolerance and DIN-rail mount make it suitable for cabinets, panels, outdoor enclosures and remote sites.

Because it supports dual-SIM failover (and optional eSIM configurations), telemetry, metering or SCADA installations can maintain connectivity even when one mobile network falters. The gateway runs RutOS — giving you native industrial protocols, firewall, VPN, data-to-server routing and remote-management (via RMS) right out of the box.

Typical Use Cases & Applications

• Remote telemetry and meter reading (water, gas, electricity) where wired connectivity is unavailable
• SCADA gateways for utilities, water treatment, waste management and infrastructure monitoring
• Industrial automation — bridging legacy RS232/RS485 sensors and PLCs to IP networks or cloud systems
• Smart-metering deployments requiring secure, managed data uplinks
• Environmental, agricultural or remote-site sensor networks (telemetry, weather, irrigation, etc.)
• Transport, fleet, logistics or mobile-asset tracking (trailers, remote equipment)
• Security, alarm panels or access control systems requiring cellular fallback
• Backup connectivity for remote CCTV, telecoms cabinets or distributed infrastructure

Why Cat 1 bis + TRB247 Is a Smart Choice

Cat 1 bis combines moderate data throughput with reduced hardware complexity — bringing many advantages for large-scale IoT, M2M and industrial deployments:

• Single-antenna design reduces cost, footprint and installation complexity
• Enough bandwidth for telemetry, sensor networks, remote data collection, SCADA data and low-bitrate telemetry — without overpaying for unnecessary throughput
• Wide network support and global LTE compatibility ensure long-term viability even as older 2G/3G networks sunset
• Dual-SIM (and optionally eSIM) architecture gives resilient connectivity for remote or mobile installations

For projects where reliability, compatibility, remote management and industrial-grade robustness matter more than raw bandwidth, the TRB247 hits the sweet spot.
