    CME Gateway A rugged low-cost, low-bandwidth modem to connect Ethernet devices to CAT-M mobile network... on the tightest budget ever!

    Are you tired of wired sensor limitations? Wouldn’t it be nice if legacy devices - like electricity meters - could send their data over the mobile network, like our phones do? With CME Gateway you can achieve just that – and more!

    It has two Ethernet ports, an on-board CPU, some RAM, and the crown jewel: a powerful built-in CAT-M narrow-band LTE modem. For extremely efficient, low-cost, low-bandwidth mobile internet connectivity. Sure, the narrowband won’t be able to stream YouTube videos, but it serves a different purpose: it offers better network coverage and transmits data via the most affordable data plans in the world.

    With the IP66 water resistance rating, the sturdy unit can survive a variety of harsh environments and setups: damp attics, rainy forests, farming equipment and so on. It has PoE-in, PoE-out, and a 2-pin DC terminal for handy powering. And to make management even easier - we’ve added a simple single-chain 2.4 GHz wireless - so you can use the MikroTik smartphone app to configure everything.

    Also, a fun bonus: the board supports GPS, so if you know your way around RouterOS scripting, you can try collecting weekly, daily or even hourly location data as well!
