Document Summary ............................................................................................................... 14 1. Overview 1.1. Introduction The RAK7248 WisGate is a device that consists of Raspberry Pi 4 Model B, RAK2287 which includes a GPS module and a Heat Sink for better performance and thermal heat dissipation management. And it’s housing is built with an aluminum casing. For the build-in RAK2287 it uses the SX1302 chip from Semtech which built-in LoRa concentrator IP core is a powerful digital signal processing engine. It is able to receive up to 8 LoRa packets simultaneously sent with different spreading factors on different channels and available in multiple variants so it can be used for internartinal standard bands. This unique capability allows to implement innovative network architectures advantageous over other short range systems. It follows Raspberry Pi specifications and is easy to mount with Raspberry Pi and RAK2287 module. WisGate is ideal for prototyping, proof-of-concept demonstration or for the evaluation. It includes a ready to use LoRaWan Gateway OS that can be connected to a LoRaWan server. Also it is developer friendly and simple even for no-so-techy users to set up LoRaWan system. It has to be the best value and function for connectivity to address a variety of applications like Smart Grid, Intelligent Farm and other IoT enterprise applications.
