EZR23T – Indoor LTE WiFi Router
Implementing an industrial mobile internet gateway for M2M (machine-to-machine) and IoT (internet of things) with strong WiFi and LAN ports.
EZR33T – Outdoor 4G WiFi CPE
IP67 waterproof enclosure ensures rugged deployments and withstands extreme weather, including MIMO external antennas and PoE injector.
Mini PCI-e and Mobile Modem
The Mini PCIe, short for Mini PCI Express, slot is a standard express card female connector interface on embedded router boards. It is much smaller than standard PCI slots, providing USB signaling in a single connector. The mini PCI-e slot supports standard 3G/4G modem modules, enabling mobile internet connectivity on the WiFi4 SIM card router. Below are the CAT 1/4/6 modems used on the EZEN3X-powered series routers.
CAT 4 LTE Modem
Global LTE Modems - CAT4
The 4G-LTE SIM card router integrates below common CAT4 LTE modems. The specific 3G/4G band support and working area vary depending on the modem. Contact us to customize the modem if the bands or the geographic regions do not cover your band or location.
