Overview and development of LoRa wireless technology in IoT application market

Entering 2022, IoT technology is becoming more and more popular in all walks of life. LPWAN technology (low-power wide area network, long-distance IoT wireless communication technology) relies on wide signal coverage, small occupied bandwidth, large number of terminal connections, NB Module and low power consumption. , low cost and other advantages, to win a high penetration rate in the global market.

Among the various LPWAN technologies worldwide, the NB-IoT module and the LoRa module are the two most widely used technologies. Among the unlicensed spectrum technologies, the LoRa module is in a dominant position. In addition to the characteristics of large network capacity, low power consumption, strong signal penetration, high-speed mobile signal stability, and positioning, the LoRa module's biggest advantage is that the wireless radio frequency communication distance is longer under the same power consumption. LoRa wireless technology can be widely used in industrial control, urban management, power grid inspection control, oil and gas pipeline monitoring, agricultural irrigation, environmental monitoring and other fields.

According to the "2022-2027 China LoRa Market Monitoring and Research and Industry Investment Feasibility General Research Report" released by the market research network, the production strength of domestic LoRa chips continues to increase, which is conducive to the development and growth of the LoRa industry. At the same time, Tencent, Alibaba, etc. have joined the LoRa Alliance one after another, which will expand the LoRa ecosystem, which has promoted the rapid growth of my country's LoRa technology and chip market. In 2021, the size of my country's LoRa IoT application market is about 21.8 billion yuan, and it is expected to grow to about 28.3 billion yuan in 2022, with a growth rate of 30%. In 2021, the shipment of LoRa chips used in the terminal field in my country is about 705.2 billion pieces, and it is expected to increase to 952 billion pieces in 2022, with a growth rate of 35%.

Although there are many application scenarios of LoRa technology in China at present, the existing LoRaWAN protocol cannot fully SPI module meet the various needs in the market. In particular, the "self-organized, safe and controllable" ecology promoted by LoRa modules in China has more and more requirements for the LoRa protocol.
