Overview
The Inventory Master’s LoRaWAN multi-class gateway with ADR & aluminum housing is a picocell LoRa gateway based SX1308 baseband chip, it must work with other operating system (Windows or Linux), when we were design it, we define this product positioning is convenient user authentication LoRa communication scheme. It supports both SPI and USB interface and can work with Windows or Linux. With well-designed structure, the great heat from SX1308 can be transferred to the Aluminum shell, making it works more stable than other products of the same type.
Features
- Dynamic data-rate adaptation (ADR)
- Support LoRaWAN class A, class B and class C
- Aluminum housing
