Description
Overview
GAOTek customizable gateway for wireless meter reading- It’s a city-level communication gateway which is based on LoRaWAN protocol, which is running on OpenWRT operating system, supporting uplink multi-channel concurrency, which can build a large capacity IoT network system more quickly and efficiently to achieve data collection, management, control and other functions of various LoRaWAN application nodes. The operating frequency band is 433 to 928MHz, which can cover 5-8km in the urban environment and more than 15KM in the rural area. It’s able to access 10000 nodes, and the gateway can access the cloud platform through 4G and Ethernet.
