26 The LG01v2 is an (% style="color:green" %)**open-source single channel LoRa Gateway**(%%). It lets you bridge LoRa wireless network to an IP network via (% style="color:green" %)**WiFi , Ethernet or Cellular Network**(%%) (via Optional 4G module). The LoRa wireless allows users to send data and reach extremely long ranges at low data rates.
27
28 LG01v2 is specially design for (% style="color:green" %)**peer to peer LoRa**(%%) protocol instead of LoRaWAN protocol. The LG01v2 use single channel LoRa module to minimize the deployment cost for a private p2p LoRa wireless network.
