TR-424 and TR-444 are both 4G industrial routers. The deciding factor is usually local Ethernet-device count rather than cellular speed: TR-424 suits compact cabinets, while TR-444 fits sites needing more local ports.
Key Takeaways
- TR-424 provides 2 LAN + 1 WAN
- TR-444 provides 4 LAN + 1 WAN
- Both require project-level confirmation of bands, Wi-Fi, serial and VPN configuration
What Should Be Compared First?
TR-424 and TR-444 are both 4G industrial routers. The deciding factor is usually local Ethernet-device count rather than cellular speed: TR-424 suits compact cabinets, while TR-444 fits sites needing more local ports. In a real project, tr-424 provides 2 lan + 1 wan and tr-444 provides 4 lan + 1 wan must be considered in the same architecture. Begin with the workload, field devices and operating model rather than one marketing specification.
How Project Conditions Change the Answer
A practical sequence is to confirm local device list and whether each device needs a dedicated port, then verify vlan or switch requirement and cabinet space, and finally test both require project-level confirmation of bands, wi-fi, serial and vpn configuration with the real equipment. Record pass criteria so the design can be repeated across sites.
Three Reminders to Avoid a Wrong Choice
Adding a separate non-industrial switch only to gain ports may add power, space and failure points, while extra ports alone do not justify the larger model. Public content and project documents should therefore state model, firmware, regional network, options and environmental conditions and avoid unverifiable claims such as 'works for every project' or 'absolute reliability'.
How Tespro Fits
Tespro TR-424 fits compact 4G backhaul such as a PLC plus HMI; TR-444 better supports multiple devices such as PLCs, HMIs, cameras and gateways.
Decision and Verification Table
| Decision factor | What to verify |
| TR-424 provides 2 LAN + 1 WAN | Confirm against local device list and document pass/fail criteria in the pilot or site test. |
| TR-444 provides 4 LAN + 1 WAN | Confirm against whether each device needs a dedicated port and document pass/fail criteria in the pilot or site test. |
| Both require project-level confirmation of bands, Wi-Fi, serial and VPN configuration | Confirm against vlan or switch requirement and document pass/fail criteria in the pilot or site test. |
Compatibility and Selection Checklist

Frequently Asked Questions
Q: Is TR-444 necessarily faster than TR-424 on 4G?
A: No. Their main published difference is port count; cellular performance depends on the regional module and network conditions.
Q: Do two local devices require TR-444?
A: TR-424 is usually the first option unless spare ports, segmentation or future expansion are required.
Q: Can a standard switch add more ports?
A: It can, but evaluate temperature, power, mounting space, management and the additional failure point.
