Patent ID: 11032847

Abstract:
The disclosure relates to a communication protocol method and device which enables, for example, the live feed of data from sensor nodes in a Wireless Personal Area Network (WPAN) to a centralized node, in particular for low-power long-range communications, further in particular with frequency chirp modulations. The disclosure provides long range communication with very low power consumption, preferably with a refresh rate of a few seconds per node while operating in the Licensed-Free Industrial/Scientific/Medical (ISM) frequency band, defined by the International Telecommunication Union (ITU). The method and device protocol include Medium Access Control (MAC) and Host functionalities that make the best use a LoRa radio, while keeping a reliable live feed of data from peripheral nodes to a central node, that is capable of managing multiple links, configured to comply with directives from Conformité Européenne (CE) and Federal Communications Commission (FCC) for the license-free radio frequency ISM bands.
