1 General Description
1.1 Product Description
RAK7258 is an indoor LoRa gateway device. Gateway uplink connects the LoRa cloud
platform by a standard Ethernet cable, making LoRaWAN wireless to internet forwarding
a breeze.
RAK7258 supports 2.4G WiFi, WiFi clients can access this gateway and setup the
gateway by wireless. It supports optional NB-IoT /Cat M module, in the absence of a
wired network, it can readily use the celullar’s network uplink data to the LoRa server
when there is no local Ethernet.
Our built-in software is based on the OpenWRT development for LoRaWAN
transmission / forwarding. It is designed for all kinds of network environment, parameter
configuration and firewall functions. Configurations and management of gateway
devices are made easy for users through the web configuration management system.
RAK7258 is built-in heat sink to dissipate the heat from the LoRa concentrator which
can withstand hot and cold environments. It can be installed on a wall and has a Power-
over-Ethernet (POE) supply mode, making it convenient for site construction and
installation.
