As a low-power wide area network (LPWAN) solution, Lo-Ra (Long Range) technology plays a vital role in the construction of smart cities. Its unique advantages and wide application scenarios make it one of the key technologies to promote the development of smart cities.   Overview of Lo-Ra technology Based on the Lora-wan (Long Range Wide Area Network) protocol, Lo-Ra technology realizes long-range wireless data communication through low-power semiconductor I Cs. Its battery power supply time is up to several years, and there is no need to build a network on the national licensed spectrum, which greatly reduces maintenance costs and operating expenses.   Main advantages Low power consumption: very suitable for Io T devices that run for a long time. Long-distance communication: The signal coverage is wide, suitable for cities and other large areas. Low cost: The operation and maintenance costs are relatively low. Free frequency band: ISM bands are used in many areas without add...
