What are the technical advantages of LoRa in the Internet of Things era?

The rapid development of the Internet of Things (IoT) puts forward higher requirements for wireless communication technologies. The LPWAN (Low Power Wide Area Network) designed for IoT applications with low bandwidth, low power consumption, long distance and large numbers of connections also rapidly arises. NB-IoT and LoRa are the typical representatives and the two most promising low-power wide area network communication technologies.

LoRa was born earlier than the NB-IoT and is a new ultra-long-haul, low-power data transmission technology based on 1GHz. LoRa uses linear FM spread-spectrum modulation, which maintains the same low-power characteristics as FSK modulation and significantly increases communication distances while improving network efficiency and eliminating interference, ie, different spread spectrum Therefore, based on this, the developed gateways can receive and process the data of multiple nodes in parallel, greatly expanding the system capacity.

Broadcom recently introduced GTi-M918 Series LoRaWAN standard protocol wireless module is an ultra-long-range LoRa module, using direct sequence spread spectrum technology, with 10 times the communication distance of the traditional technology, 1/10 the power consumption of traditional wireless technology , Battery life of up to ten years, multi-functional interface, support for I2C / UART / SPI communication (with U.FL socket). Broad Luster GTi-M918 series lora module to meet the needs of self-network and wireless data acquisition can be widely applied to security monitoring, remote meter reading, intelligent building, intelligent transportation, smart municipal, intelligent cloud water purification, smart home and other objects Networking industry applications such as system installations, to meet the needs of developers.

The benefit of LoRa over NB-IoT is that there are already mature business cases, and NB-IoT has just begun. LoRa and NB-IoT applications may have many overlapping, but NB-IoT is dominated by the operator, to use the operator's network, so the data is up to the operator where many companies may not be willing to put their own Data to others, so these companies prefer to deploy their own private IoT, this time with LoRa is appropriate.
