Ease of installation with support for PoE
By integrating Power over Ethernet (PoE), GL-S20 transmits power and data over a single ethernet cable. You’ll have power to more areas without having to install additional electrical infrastructure—saving on extra costs in the long run.
Your pathway to a scalable IoT network
Manage and control all your IoT devices effortlessly with GL-S20, the ultimate solution for building a robust, scalable network for all your IoT devices. GL-S20 when used as a Thread Border router bridges your LAN network and other GL-S20s functioning as Thread routers seamlessly. GL-S20’s self-healing capability ensures a resilient network infrastructure, even in the face of network disruptions. In case one of the Thread routers fails unexpectedly, the network reconfigures automatically using a neighboring Thread router, ensuring your connection remains rock-solid at all times.
