Queclink WR310-FNA vs Teltonika RUTM55 – Industrial 5G Router Comparison

Choosing the right 5G industrial router depends on your application, environment, and future requirements. Both the Queclink WR310-FNA and the Teltonika RUTM55 are rugged, carrier-grade devices designed for IoT, transport, and enterprise connectivity — but they differ in some key areas.

Performance & Connectivity

WR310-FNA: Delivers reliable 5G Sub-6 GHz connectivity with LTE Cat 19 fallback. It supports both SA and NSA modes, ensuring flexibility across networks.
RUTM55: Provides higher peak throughput — up to 3.4 Gbps downlink and 550 Mbps uplink — making it more suitable for data-heavy applications such as video streaming or industrial analytics.

Verdict: If absolute speed is critical, the RUTM55 has the edge. For balanced performance with strong fallback, the WR310 is a dependable choice.

WiFi Capabilities

WR310-FNA: Equipped with WiFi 6 (802.11ax), supporting higher capacity, reduced latency, and better efficiency in dense environments.
RUTM55: Uses WiFi 5 (802.11ac), which is stable and proven but lacks the efficiency of WiFi 6 in high client density setups.

Verdict: WR310 wins if your deployment relies heavily on wireless LAN with multiple devices.

SIM & Redundancy

WR310-FNA: Dual SIM with intelligent auto-switching based on signal loss, network denial, or connection failure.
RUTM55: Dual SIM plus eSIM support, allowing remote profile provisioning and flexible global deployments.

Verdict: RUTM55 offers more flexibility, especially for organisations looking to adopt eSIM across multiple regions.

Industrial Interfaces

WR310-FNA: Features RS232 and RS485 serial ports, making it suitable for SCADA, PLC integration, and legacy industrial systems.
RUTM55: Includes RS232/RS485 plus digital I/O and relay functions, giving additional flexibility for remote monitoring and control.

Verdict: RUTM55 edges ahead for complex installations that require multiple input/output options.

Hardware & Durability

WR310-FNA: Compact at 130 × 100 × 45 mm and 552 g, with aluminium housing, −30°C to +70°C operating range, and 8–32V DC input.
RUTM55: Slightly larger and heavier, with a broader operating range of −40°C to +75°C and a wider 9–50V DC input.

Verdict: RUTM55 is better for extreme industrial environments. WR310 is more compact and lighter for space-constrained installations.

Software & Management

WR310-FNA: Runs on an OpenWRT-based OS with strong customisation options, VPN support, firewall features, and Queclink’s Nebulink remote management system.
RUTM55: Powered by RutOS, widely regarded for its industrial protocol support, user-friendly interface, and tight integration with Teltonika RMS for centralised management.

Verdict: RUTM55 provides a more polished out-of-the-box ecosystem, while WR310 offers flexibility for integrators who prefer OpenWRT.

Use Case Recommendations

Choose WR310-FNA if:
You need WiFi 6 for modern, dense deployments
