LoRa wireless technology will bring new opportunities for innovative applications of Internet of Things


    Networking has been the internal demand for Internet of Things to develop, while wireless connection technologies are no longer satisfied with short-range communication and moving towards to longer-distance and wider-coverage, so the low-power wide area network (LPWAN) came into being. As a wireless technology in low-power wide area network (LPWAN), LoRa is more mature in industry chain development and has earlier commercial applications compared to other wireless technologies (such as Sigfox and NB-IOT and so on). Besides, Semtech also cooperates with a number of semiconductor companies (including ST and Microchip) to provide chip-level solutions that will help customers get LoRa products and use LoRa wireless technology to implement applications of Internet of Things.
   Main features of LoRa wireless technology:
  Long-distance: 1 ~ 20 km
  Number of nodes: 10,000 degree, even 1 million degree
  Battery life: 3 to 10 years
  Data rate: 0.3 – 50 kbps
  As a wireless technology, LoRa is easier to communicate in lower power consumption and long-distance in Sub-GHz band. It can be battery-powered or powered by energy harvesting.The lower data rate also extends the battery life and increases the capacity of the network. LoRa signal has a strong penetration to the building. These technical features make LoRa more suitable for low-cost large-scale deployment of Internet of Things.
  LoRa applications
  In terms of application, LoRa is mainly used in data transparent transmission and LoRaWAN protocol currently. The LoRa is more used in data transparent transmission, and because the gateway technology and development is difficult, the application in LoRaWAN protocol networking is less.
  Some concerns in LoRa applications:
  Distance or range
  Power supply or consumption
  Number of node
  Application scene
  Generally, the range of wireless distance is about 1 to 2 km in city, and farther in suburbs or open areas. Topology network deployment can be deployed according to the specific application and scene design. LoRa is suitable for the applications of low communication frequency and less amount of data. A gateway can connect to several nodes or terminal equipments. The official explanation of Semtech is as follows: a SX1301 has eight channels, so using LoRaWAN protocol can receive about 1.5 million packages of data every day. If your application sends a packet per hour, then a SX1301 Gateway can handle approximately 62,500 terminal devices.
  In terms of network applications, LoRa is divided into large network and small network. Small Network means that the user produce a system network by setting nodes, gateways and servers by himself; large network is a wide range of basic network deployment, just like the communication network of Chinese Mobile. In terms of industry practitioner, many telecom operators are also involved in LoRa. For the increase of LoRa devices and networks, the mutual spectrum interference exists, from which a problem about the communication spectrum allocation and management rises, requiring a unified and coordinated management mechanism and a large network management.
  A message from FN-LINK: FN-LINK R&D center iLive has designed LoRa module that meets customer needs. The production of LoRa module will facilitate the construction of smart city networks and promote the development of the industrial chain. FN-LINK will focus on the applications of LoRa technology in all sectors, and take efforts to build the "hardware production platform", "technology platform", "program verification platform" and "market platform for cooperation" for LoRa applications in China.       Connection is a key point of the entrance of network, network is a key point of Internet of Things, and FN-LINK is a key point of wireless hardware application design!
