Overview
The Inventory Master LoRa gateway, 4G multi-network, external antenna & multi-channel support is used for ultra long distance spread spectrum communication. Built-in three RF chips SX 1278 has a high sensitivity of -148 dBm and a power output of 20 dBm, long transmission distance and high reliability, it can send and receive data on three RF channels at the same time. Each channel can be set with different operating frequency and rate parameters without interfering with each other. Automatically select idle channels to send and receive data when working under high load. Under the premise of low cost, three channel communication with LoRa nodes is realized, and higher communication efficiency is realized.
