Network deployment

LoRa network has been in the world for more pilot or deployment. According to the earlier data released by LoRa Alliance, nine countries have started to build networks and 56 countries have started piloting. China AUGTEK completed 284 base stations in the Beijing-Hangzhou Grand Canal, covering 1300Km watershed. US network operator Senet completed 50 base stations in North America in 2015, covering 15,000 square miles (about 38,850 square kilometers) The first phase of the completion of more than 200 base stations set up; France Telecom-Orange announced in early 2016 in France network; Royal Dutch telecommunications kpn announced that it will build a network in New Zealand, 2016 years ago to reach 50% coverage; India Tata announced in Mumbai and Telstra announced that it will be piloted in Melbourne ... ...

LoRaWAN agreement

LoRaWAN is a low power Wide Area Network (LPWAN) standard based on the open source MAC layer protocol introduced by the LoRa Alliance. This technology can provide local, national or global networks for battery-powered wireless devices. LoRaWAN is aimed at some of the core needs of the Internet of Things, such as secure two-way communication, mobile communication, and static location identification services. The technology without the need for local complex configuration, you can make intelligent devices to achieve seamless interoperability between the Internet to the field of users, developers and businesses free operation authority.

LoRaWAN network architecture is a typical star topology, in this network architecture, LoRa gateway is a transparent transmission of the relay, connecting the terminal equipment and back-end central server. Between the gateway and the server through the standard IP connection, the terminal device with a single hop with one or more gateway communication. All nodes and the gateway are two-way communication between, but also support the cloud upgrade and other operations to reduce the cloud communication time.
