PG1302 LoRaWAN Concentrator 5 / 20
1 Introduction
1.1 What is PG1301 LoRaWAN Concentrator?
The PG1302 is a multi-channel high performance transmitter/receiver designed to
simultaneously receive several LoRa packets using random spreading factors on random
channels. Its goal is to enable robust connection between a central wireless data
concentrator and a massive amount of wireless end-points spread over a very wide range of
distances.
The PG1302 is design to use with Raspberry Pi to build smart metering fixed networks and
Internet of Things applications with up to 5000 nodes per km2 in moderately interfered
environment.
