An office router lives on a shelf in an air-conditioned room with a fibre line. An industrial router lives somewhere less comfortable – a cabinet on a construction site, a kiosk in a mall, a bus, a pump station, a rooftop – on a cellular connection, and it is expected to keep a critical system online for years without anyone visiting it. Teltonika makes industrial cellular routers for exactly this, and this article explains what they do, which models exist and how to deploy them.
What makes a router industrial
- Cellular WAN – built-in 4G LTE (and 5G on top models) modems with dual SIM slots for carrier failover, and antenna connectors for external antennas.
- Environment – metal housings, wide operating temperatures (typically -40 to 75 degrees), DIN-rail and wall mounting, and a wide DC input range for vehicle and solar power.
- Reliability features – hardware watchdog, automatic reboot on connectivity loss, ping-based failover, and firmware that recovers from bad updates.
- Security – firewall, VPN (OpenVPN, IPsec, WireGuard, ZeroTier), VLANs and access control, so the remote site is part of the corporate network rather than a hole in it.
- Remote management – a cloud platform (Teltonika RMS) for monitoring, configuration and firmware across a fleet, without a site visit.
The Teltonika range
RUT2xx series – compact LTE routers with one or two Ethernet ports for a single device or a small site: a kiosk, a payment terminal, a sensor gateway.
RUT9xx series – four-port LTE routers with Wi-Fi, dual SIM and I/O for small sites and vehicles.
RUTX series – Gigabit LTE and 5G routers with dual SIM, Wi-Fi, multiple Ethernet ports, GNSS and I/O, for sites that need throughput and redundancy: branch offices, construction sites, retail, transport.
TRB gateways – LTE gateways with serial and I/O interfaces for connecting industrial equipment (covered in a separate article).
TSW switches – industrial Ethernet switches, managed and unmanaged, with PoE, to extend the site network.
Where they are used in the region
Construction site offices and cameras before fixed lines arrive. ATMs, kiosks and vending machines. Retail branches and pop-up stores as primary or backup WAN. Buses, trucks and fleet vehicles. Oil and gas well sites, pump stations and pipeline monitoring. Solar farms and substations. Digital signage in public spaces. Temporary events and exhibitions. In each case the router is the only link, and its reliability is the system’s reliability.
Choosing a model
Count devices and throughput: one device, a RUT2xx; a small site, a RUT9xx; a branch or a high-bandwidth site, a RUTX. Decide on dual SIM for carrier redundancy. Check the frequency bands against the carriers where the router will be used. Choose external antennas for cabinets and vehicles. Specify power: PoE, DC from a vehicle, or a solar system. Add a TSW switch if the site has more devices than the router has ports.
Deployment practice
- Enrol every router in RMS before it ships to site, with a standard configuration template.
- Configure VPN to the corporate network so that the site is reachable and its traffic is protected.
- Set up the failover rules and the watchdog; test by pulling the SIM.
- Mount antennas where the signal is, not where the cable is short.
- Label the SIMs and record ICCIDs against sites for carrier support.
