Choosing the right cellular router depends on the job, the environment and the lifecycle of the deployment. Millbeck partners with eight specialist vendors to cover the full spectrum of professional connectivity needs, from compact M2M gateways to mission-critical 5G platforms. Here is an overview of each range and where it fits best.

Teltonika Routers

Teltonika is the industry's go-to manufacturer for professional IoT connectivity, widely regarded as a benchmark for value, feature depth and long-term reliability. Their portfolio is built around three complementary families: the core RUT series, the next-generation RUT C platform, and the purpose-built OTD outdoor range.

The core RUT series covers the widest ground, with models such as the RUT241, RUT951, RUT956, RUTX11 and RUTX50 spanning entry-level 4G LTE Cat 4 through to dual-SIM 5G with Wi-Fi. These devices are the backbone of professional IoT deployments across remote monitoring, smart city infrastructure, transport, retail and automation, combining rugged build quality with multiple interfaces including Ethernet, Wi-Fi, serial and digital I/O.

The RUT C series, headlined by the RUTC50, is Teltonika's next-generation platform for advanced industrial and high-density environments. It delivers 5G speeds up to 3.4 Gbps with LTE Cat 20 fallback, dual-band Wi-Fi 6, dual-SIM plus eSIM and five Gigabit Ethernet ports. Enhanced processing (1 GB RAM, 8 GB flash) supports edge computing workloads and up to 512 concurrent users, making it well suited to transport, large CCTV estates and future-proofed enterprise deployments.

The OTD outdoor series, including the OTD144 (4G) and OTD500 (5G), integrates high-gain antennas within an IP55-rated weatherproof housing. These units eliminate signal loss from long cable runs and provide an all-in-one solution for mast-head or pole mounting. Both support PoE-in and PoE-out over Gigabit Ethernet, making them ideal for CCTV backhaul, solar farms, public Wi-Fi and construction sites.

Proroute H Series Routers

Proroute H series routers are engineered in the UK for IoT and M2M connectivity, with a strong track record in CCTV, utilities, telemetry and unattended site deployments. The range includes the compact H685 (available in 4G LTE Cat 4, Cat 6 and 5G variants), the H820 with four Ethernet ports, and the dual-SIM H900 with 4G or 5G options. Features include embedded cellular modems with 3G and 2G fallback, Gigabit Ethernet, Wi-Fi, RS232/RS485 serial, digital I/O, VPN support and wide DC input ranges for industrial and vehicle installations. Proroute also offers embedded custom boards for OEMs who need a tailored solution built around proven hardware.

Robustel Routers

Robustel is a leading manufacturer of industrial-grade IoT and M2M connectivity hardware, trusted by operators and system integrators in over 100 countries. The portfolio spans 4G LTE routers (R1510, R1511, R2010, R2011, R2110), the R2000 and R3000 series with dual-module and LoRaWAN options, elevator-specific gateways like the R3010, and the R5020 flagship 5G router. All devices run RobustOS, a secure Linux-based platform offering dual-SIM failover, VPN (IPsec, OpenVPN, GRE, L2TP), SD-WAN integration and rugged builds rated for extreme temperatures. The Robustel Cloud Manager Service (RCMS) provides centralised monitoring, configuration and firmware management across large estates. Robustel routers are well suited to energy and utilities, smart cities, transport, retail, EV charging and maritime applications.

Semtech (Sierra Wireless) Routers

Semtech's AirLink portfolio, formerly Sierra Wireless, is one of the longest-established names in cellular networking. The range includes the RV55 compact LTE router for fixed and mobile assets, the XR60 ultra-compact 5G router, the XR80 high-performance 5G router with Wi-Fi 6 and a cartridge-based upgrade path, and the flagship XR90 vehicle router with dual 5G modems and dual independent 4x4 Wi-Fi 6 antennas. A newer addition, the RX400, targets power-efficient 5G RedCap deployments. AirLink devices are managed through AirLink Management Service (ALMS) and paired with AirLink Complete support packages. These routers are typically specified for public safety, transit, first responder fleets, utilities and mission-critical industrial applications where resilience and certified reliability matter most.

Milesight Routers

Milesight IoT is a fast-growing, innovation-driven manufacturer with a focus on 5G, AI, IoT and LoRaWAN. The router range covers the entry-level UR41 Mini with ultra-low power consumption, the UR32 Lite series for cost-sensitive 4G deployments, the UR35 Pro series with dual-SIM, serial and DLMS support for smart metering, and the UR75 Ultra flagship with 5G sub-6 GHz (SA and NSA), Wi-Fi 6 and a quad-core ARM Cortex-A55 CPU. All models feature robust IP30 aluminium enclosures, wide temperature ranges, hardware watchdogs, Python SDK for custom development, and support for VPN tunnels including ZeroTier, WireGuard, IPsec, OpenVPN and DMVPN. Milesight DeviceHub offers centralised fleet management, and integration with the wider Milesight LoRaWAN gateway and sensor ecosystem makes the range particularly strong for smart building, smart agriculture and smart city projects.

Ericsson Cradlepoint Routers

The Ericsson Cradlepoint range pairs enterprise-grade 5G and LTE routers with the NetCloud management platform to deliver Wireless WAN, SD-WAN and zero-trust security from a single cloud console. Key products include the E300 series for branches, pop-up locations, clinics and retail, and the E3000 series for larger fixed branches, healthcare and financial sites where PoE switching, fibre SFP slots and Gigabit-class 5G performance are required. NetCloud subscriptions cover routing, VPN, SD-WAN, security, firmware updates and 24x7 Ericsson support for the life of the subscription, with a limited lifetime hardware warranty. This combination suits organisations that want carrier-grade wireless WAN capability and centralised policy control across distributed sites, with the assurance of an Ericsson-backed roadmap.
