MKGW8 Indoor LTE Gateway

MKGW8 is a dual-module indoor LTE gateway, based on the BLE 5.0 protocol, with built-in Ethernet connectivity. There is also an onboard Wi-Fi (supporting 2.4 GHz, with 5 GHz optional) for easy wireless connection, as well as 4G LTE uplink support. It supports MQTT SSL/TLS encryption and PoE cascading, making it simple to deploy in any site condition.

The Linux-based BLE gateway enables powerful data processing with various beacons and customizable filtering rules to capture only the expected BLE data. Intelligent network switching automatically selects the most stable backhaul across Ethernet, Wi-Fi, and Cellular. MKGW8 is well-suited for real-time location services, asset tracking, condition monitoring, and personal safety management.

Powerful Data Processing and Security

Built on a stable Linux-based system, MKGW8 uses customizable filters to capture specific BLE data. This reduces bandwidth usage and improves upstream efficiency. It secures transmissions via MQTT V3.1.1 and HTTP with SSL/TLS encryption. Data is delivered in a standard JSON format for easy integration with third-party platforms.

Remote Management & PoE Cascading

Lower deployment and maintenance costs with simplified connectivity.

PoE Cascading: Support for PoE input and output allows for daisy-chaining multiple gateways, reducing cabling in large sites.
Dual Power: Flexible power options via PoE or 12V/2.5A DC.
Remote Maintenance: It also supports remote downlink commands and OTA firmware updates.
