TLG7921M 16 Channels Outdoor Gateway

Model : TLG7921M

Overview :

It is a highly integrated and intelligent LoRaWAN® communication 16 channels LoRa®-enabled gateway independently designed and developed by the Kiwi technology. It supports the built-in standard LoRaWAN® network protocol and uses an ARM-Cortex A53 industrial-grade processor to provide the IoT with secure full-duplex communication services, allowing enterprise users to have their own IoT system to en able customized smart services. It supp orts various wireless communication functions such as LoRa® , LBT, GPS and 3G/4G, as well as Ethernet 10/100M wired interface, and a built-in secure chip. The product is designed according to industrial grade and IP67 rating.
