Cellular routers
Rugged 4G LTE and 5G routers with Ethernet LAN, plus serial, Wi-Fi and I/O on some models.

Overview
Lantronix cellular routers are ruggedized industrial routers that provide 4G LTE or 5G WAN connectivity with Ethernet LAN ports, and on some models serial, Wi-Fi and I/O. Most models run a Linux-based OS and offer an SDK so integrators can build and install custom applications. They can be managed locally through a web UI and CLI, or remotely through Percepxion and standard protocols such as SNMP, TR-069 and LwM2M.
Built for
- Cellular primary or backup WAN for remote sites
- Utility and energy telemetry
- Serial equipment over cellular
- Vending, kiosks and digital signage
Key features
LTE and 5G models
The range covers LTE Cat 1 bis (NTC-201), Cat 1 (NTC-220), LTE-M to Cat 4 (E210) and 5G NR (NTC-500).
Linux and SDK
NTC-201 and NTC-220 run a Linux-based OS with an SDK for applications in ANSI C, shell script and Lua.
Serial and I/O
NTC-220 and E210 include RS-232 (with RS-485 options) and configurable I/O for industrial equipment.
Dual SIM
E210 supports dual SIM in single standby, and NTC models accept an optional soldered-down MFF2 SIM.
Remote management
Routers support HTTPS web UI, SSH CLI, SNMP v3, TR-069, LwM2M and MQTT, depending on model.
