LoRa is a low-power LAN wireless standard developed by semtech. Its name is remote radio. Its biggest feature is that it travels farther than other wireless modes under the same power consumption, realizing the unity of low power consumption and long distance, and it is 3-5 times longer than the traditional wireless radio frequency communication distance under the same power consumption.
LoRa is a low-power LAN wireless standard based on Semtech, and its purpose is to solve the contradiction between power consumption and transmission distance. Generally speaking, low power consumption means short transmission distance.
High power consumption leads to long transmission distance. By developing LoRa technology, the technical problem of longer transmission distance than other wireless modes under the same power consumption condition is solved, and the unity of low power consumption and long distance is realized.
LoRaWAN open specification is a low-power wide area network (LPWAN) standard based on Semtech LoRa equipment, which uses unlicensed radio spectrum in industrial, scientific and medical (ISM) frequency bands. LoRa Alliance (a non-profit association and a fast-growing technology alliance) promotes the standardization and global coordination of LoRaWAN standards.
LoRaWAN standard provides efficient, flexible and economical solutions for practical problems in rural and indoor use. In these cases, cellular, Wi-Fi and Bluetooth low power (BLE) networks are ineffective.
