What is LoRa?
LoRa, short for Long Range, is a low-power, long-range wireless communication technology developed to enable secure data transmission over extensive distances. It operates on unlicensed radio frequency bands, making it accessible for a wide range of applications without the need for expensive infrastructure. LoRa is the underlying technology for LoRaWAN (Long Range Wide Area Network), a protocol that ensures seamless communication between devices and gateways.
Understanding LoRaWAN
LoRaWAN is a key player in the Internet of Things (IoT) landscape. It acts as the backbone for enabling long-range communication between sensors, devices, and cloud platforms. LoRaWAN operates in a star-of-stars topology, where individual devices communicate with central gateways that forward data to the cloud or a central server. This architecture enables extensive coverage with minimal infrastructure and supports bidirectional communication, allowing devices to receive commands from the network.
How LoRa Works for Wireless Data Reading
