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

An apparatus for acquisition of fast multi-channel data based on a long range wide area network (LoRaWAN), the apparatus comprising:

• 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;
• and
• a data transmitter configured to insert the flag of the apparatus itself into the DTQ, take out one flag from the DTQ at each round, and transmit data when the flag is the flag of the apparatus during a data transmission period.
