What is LoRa WAN technology?
LoRa WAN is a low power wide area network technology (LP-WAN) designed for Internet of Things (IoT) and smart sensor applications. As the name implies, long range transmission capability with less power consumption makes LoRa a significant player in IoT networks.
In LoRa technology, a message transmitted by any device can be received by single or multiple gateways. The received messages will be forwarded to the central network for processing. Smart server architecture will handle these messages to each related applications.
LoRa alliance is an open, nonprofit organization of members that standardize, develop, monitors and improves LoRa standard. Internet of Things is one of the major drivers behind this highly efficient LP-WAN technology.
