Mikrotik CME Gateway gateway/controller 100 Mbit/s White IP66

The Mikrotik CME Gateway gateway/controller 100 Mbit/s White IP66 provides a compact solution to connect legacy or fixed devices to mobile networks. It combines two Ethernet ports, onboard CPU and RAM, and an integrated CAT‑M narrowband LTE modem to enable low‑bandwidth, low‑cost mobile data transmission. The unit is IP66 rated for dust and water resistance and supports Power over Ethernet (PoE‑in and PoE‑out), a 2‑pin DC terminal, and a built‑in 2.4 GHz wireless interface for simplified configuration via the MikroTik smartphone app. The board also offers GPS support for optional location tracking when used with RouterOS scripting.

Advantages

The device delivers reliable mobile connectivity using CAT‑M narrowband LTE, which provides extended coverage and reduced data costs compared with standard broadband LTE. Its IP66 enclosure makes it suitable for outdoor and harsh environments. Dual Ethernet ports, PoE‑in/out and a 2‑pin DC terminal provide flexible powering and integration options. Onboard CPU (QCA9531, 650 MHz) and 16 MB internal memory support gateway/controller functions at up to 100 Mbit/s while a 2.4 GHz wireless interface enables easy local setup and management.

Suitable for

• Connecting legacy devices such as electricity meters or sensors to mobile networks
• Remote telemetry and low‑bandwidth IoT data collection
• Deployments in harsh or outdoor locations requiring IP66 protection
• Installations needing flexible power options (PoE or DC)

How to use

Install the device in a location with adequate mobile network coverage and mount it according to environmental requirements to preserve the IP66 rating. Insert a NanoSIM card, connect required Ethernet devices to the ports, and choose a power source: PoE‑in, PoE‑out or the 2‑pin DC terminal. Use the onboard 2.4 GHz wireless and the MikroTik smartphone app or RouterOS web interface to configure network settings, mobile data parameters and routing rules. If needed, enable GPS support and add RouterOS scripts to collect location data at desired intervals.

Recommendations

For optimal performance, use a CAT‑M service plan with sufficient uplink allowance for periodic telemetry. Place the gateway where it receives stable cellular signal and secure cable entries to maintain IP66 protection. Regularly update RouterOS and review configured scripts to ensure reliable data transmission and device security.
