MikroTik CME Gateway
- SKU: CME22-2n-BG77
Product Information
Introducing a robust, cost-effective, low-bandwidth modem designed specifically for seamless Ethernet connectivity to the CAT-M mobile network, catering to budget-constrained applications.
Are you facing limitations with wired sensors? Imagine enabling legacy devices, such as electricity meters, to transmit data over the mobile network, akin to modern smartphones. With the CME Gateway, this is now possible—and much more.
Equipped with dual Ethernet ports, an integrated CPU, and sufficient RAM, the standout feature is its high-performance built-in CAT-M narrowband LTE modem. While it may not support high-bandwidth applications like video streaming, it excels in delivering reliable connectivity with superior network coverage at minimal data costs. Designed with an IP66 rating, this rugged unit can withstand various harsh environments, making it suitable for damp attics, rainy forests, agricultural machinery, and beyond.
It features Power over Ethernet (PoE) for both input and output, as well as a 2-pin DC terminal for versatile powering options. For enhanced management, we've included a streamlined single-chain 2.4 GHz wireless interface, allowing easy configuration through the MikroTik smartphone app. As an added advantage, the board is GPS-enabled, offering opportunities for those proficient in RouterOS scripting to capture and log location data at customizable intervals—be it weekly, daily, or hourly. This modem is tailored for professionals seeking effective solutions in IoT and device connectivity.
