Apparatus and method for acquisition of fast multi-channel data based on LoRaWAN

摘要

An apparatus for acquisition of fast multi-channel data based on a long range wide area network (LoRaWAN) includes: a contention period data processor configured to insert a flag indicating the apparatus itself into an initial contention resolution queue (CRQ), determine whether a flag is a flag of the apparatus, and transmit an access request sequence (ARS) during a contention period; a feedback period data processor configured to check whether information taken out from a data transmission queue (DTQ) is a flag of the apparats, check whether a contention of the apparatus is resolved, and check whether there is a slot for which contention is not resolved among other slots during a feedback period.
