Industrial 4G & 5G Routers for Remote Sites
Construction compounds, pumping stations, pop-up sites, CCTV poles: where fibre doesn't go, a rugged cellular router is the WAN. Pick by bandwidth, temperature rating and how badly failure hurts.
The WAN in a metal box
An industrial 4g router does one job that matters: it keeps a remote site online without an engineer visit. The difference from the domestic router in your office is everything around the radio — DIN-rail mounting, wide temperature tolerance, dual-SIM failover, VPN tunnelling and I/O that survives a plant room rather than a living room.
The buying decision is bandwidth versus environment versus consequence. A telemetry cabinet needs kilobits and reliability; a CCTV pole needs steady upstream megabits; a pop-up office needs real throughput for people. Check coverage for each candidate network at the actual site first — Ofcom’s coverage checker is the honest baseline — then size the industrial 4g router to the duty.
The industrial 4g router line-up (and the 5G step-up)
From compact telemetry routers to full 5G site connectivity. All are unlocked — fit any operator’s SIM, or multi-network roaming SIMs for the best mast wherever the site lands.

Sizing, SIMs and staying online
Start with consequence of failure. If a dropped connection means a silent alarm or a blind camera, spec dual SIM on two networks and a router that watches its own link (the UR35 class does) — failover happens in seconds without a site visit. If it means a slow afternoon in a site office, a single good SIM is fine and the budget goes to bandwidth instead.
SIM strategy beats router strategy: multi-network roaming SIMs attach to the strongest local mast and remove the ‘wrong operator for this postcode’ gamble, which matters more than any spec-sheet number for mobile or multi-site fleets. For VPN back to base, IPsec and OpenVPN are standard across the range — a hub-and-spoke tunnel design serves most estates without drama.
- Dual SIM + link monitoring wherever failure means a silent alarm
- Multi-network roaming SIMs remove per-site operator roulette
- External antenna ports matter in metal cabinets — budget for antennas
- A wide-temperature industrial 4G router lives happily in unheated cabinets
- 5G earns its premium on CCTV backhaul and staffed site offices
- Serial/IO on the UR35 class doubles as a mini RTU for legacy plant
Where these fit in the bigger picture
Cellular routers carry whole remote sites; individual sensors mostly should not each carry a SIM. The economic pattern is a router (or LoRaWAN gateway with cellular backhaul) per site, with battery sensors hanging off it — connectivity once, sensed everything. CCTV poles pair a router with a PoE switch to power the cameras from the same cabinet.
SCADA and legacy plant ride the same links — see the SCADA & remote I/O solution for serial-to-cloud patterns, and IoT for construction for the temporary-site playbook.
Two further options are quoted rather than listed. The ATOP CR5201B is a very low-power LTE gateway built for solar, battery and other power-constrained outstations, and the ATOP CWR5805 is a 5G/4G/Wi-Fi router for harsh field deployments. Both are rugged-housing, wide-temperature, high-EMC units priced per project rather than per box — ask for a quote and we will come back within one working day.

Frequently asked questions
Which network's SIM should we use?
Whichever is strongest at that site — check Ofcom’s coverage map, then verify on the ground with a phone on each candidate network. For fleets or mobile assets, multi-network roaming SIMs sidestep the question entirely by attaching to the best available mast; every router we sell is unlocked, so you are never tied to an operator.
Do we need 5G, or is 4G enough?
4G comfortably carries telemetry, SCADA, payment terminals and a small office. 5G earns its premium when the duty is multiple CCTV streams, large file movement or a staffed site office with real users — or where local 4G is congested. Buying 5G ‘for the future’ on a telemetry cabinet is money better spent on a second SIM.
Can these VPN back to our head office?
Yes — IPsec, OpenVPN and similar tunnelling are standard, and the usual design is hub-and-spoke back to your firewall so remote sites appear as branch networks. We can advise on tunnel architecture if your IT team wants a second opinion.
What is the difference between an industrial 4g router and a LoRaWAN gateway?
An industrial 4g router connects a site (Ethernet/Wi-Fi devices) to the internet; a LoRaWAN gateway connects battery sensors to a network. They are complements, not rivals — many sites run a UG65 gateway for the sensors with a UR35 router providing its backhaul.

The short answer
What makes a 4G router industrial rather than consumer?
Four things, none of them speed: a wide DC input rather than a mains plug, an operating range that starts at -40 degrees C, DIN rail mounting, and serial ports with a Modbus gateway so field equipment can reach the network. A consumer 4G router has none of these and is not specified to run unattended for years.
