LoRa (short for long range) is a spread spectrum modulation technique derived from chirp spread spectrum (CSS) technology. Semtech’s LoRa is a long range, low power wireless platform that has become the de facto wireless platform of Internet of Things (IoT). LoRa devices and networks such as the LoRaWAN® enable smart IoT applications that solve some of the biggest challenges facing our planet: energy management, natural resource reduction, pollution control, infrastructure efficiency, and disaster prevention. Semtech’s LoRa devices have amassed several hundred known uses cases for smart cities, homes and buildings, communities, metering, supply chain and logistics, agriculture, and more. With hundreds of millions of devices connected to networks in more than 100 countries and growing, LoRa is creating a smarter planet.
Features
- The spread spectrum modulation technology used by LoRa (abbreviation of long range) is derived from chirp spread spectrum (CSS) technology, which is one of long-distance wireless transmission technology and LPWAN communication technology. At present, LoRa mainly operates in the ISM frequency band, mainly including 433 , 868, 915 MHz, etc.
- LoRa technology integrates technologies such as digital spread spectrum, digital signal processing and forward error correction coding, which greatly improves the performance of long-distance communication. LoRa’s link budget is better than any other standardized communication technology. The main factors that determine distance in a given environment
- LoRa RF chips mainly include SX127X series, SX126X series, SX130X series, of which SX127X, SX126X series are used for LoRa nodes, and SX130X is used for LoRa gateways.
