RAK7268 WisGate Edge Lite 2 Datasheet
Overview
Description
The RAK7268 WisGate Edge Lite 2 is a full 8-channel indoor gateway, based on the LoRaWAN protocol, with built-in Ethernet connectivity for a straightforward setup. There is an onboard Wi-Fi setup (supporting 2.4 GHz Wi-Fi) that allows it to be easily configured via the default Wi-Fi AP mode. Additionally, the gateway supports LTE uplink communication connections (optional).
As with the other RAKwireless Industrial Gateways, it also supports MQTT Bridge mode, with the option for TLS authentication.
Power-over-Ethernet (PoE) is supported to serve cases where wall or ceiling mounting is required without the need to install additional power lines.
The open-source software for the management and configuration of this gateway device is based on OpenWRT. It has a built-in LoRa packet forwarder and a graphical user interface, allowing for a quick setup without giving up the freedom of a fully customized solution.
RAK7268 also supports the MQTT Bridge function, can use the MQTT integrated to third-party platforms.
RAK7268 is especially suitable for small and medium-sized deployment scenarios in industry applications, saving the additional cost for server and R&D investment, and has the advantages of high execution efficiency.
