LG02-P an open source 4G Dual Channels LoRa IoT Gateway

LG02-P is an open source dual channels LoRa Gateway. It lets you bridge LoRa wireless network to an IP network via WiFi, Ethernet, 3G or 4G cellular. The LoRa wireless allows users to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity.

LG02-P has Rich Internet Connection method such as WiFi interface, Ethernet port and USB host port. These Interfaces provide flexible methods for users to connect their sensor networks to Internet.

LG02-P can support the LoRaWAN protocol in single frequency and customized LoRa transmit protocol. The design of LG02-P is use the Linux to directly control two sx1276/sx1278 LoRa modules which lets the LoRa can works in full duplex LoRa mode and increase the communication efficiency.

LG02-P can be used to provide a low cost IoT wireless solution to support 50~300 sensor nodes.

Except LoRaWAN mode, LG02-S can support mutiply working mode  such as: LoRa repeater mode, MQTT mode, TCP/IP Client mode, TCP/IP Server mode to fit different requirement for IoT connection. Click this link for more info about the modes.

LG02-P base on sx1276 solution which provide a low cost for your IoT network connection. Compare to the cost with normal SX1301 LoRaWAN solution. the LG02-S is only of its 1/4 or less cost. This make the LG02-P very suitable to set up small scale LoRa network or use it to extend the coverage of current LoRaWAN network.
