LoRaWAN ® L2 1.0.4 Specification © 2020 LoRa Alliance ® Page 85 of 90 The authors reserve the right to change specifications without notice. 17 Revisions 2532 17.1 Revision 1.0 2533 Approved version of LoRaWAN1.0 2534 17.2 Revision 1.0.1 2535 Clarified the RX window start time definition 2536 Corrected the maximum payload size for DR2 in the NA section 2537 Corrected the typo on the downlink data rate range in 7.2.2 2538 Introduced a requirement for using coding rate 4/5 in 7.2.2 to guarantee a maximum 2539 time on air < 400 mSec 2540 Corrected the JoinAccept MIC calculation in 6.2.5 2541 Clarified the NbRep field and renamed it to NbTrans in 5.2 2542 Removed the possibility to not encrypt the Applicative payload in the MAC layer , 2543 removed the paragraph 4.3.3.2. If further security is required by the application , the 2544 payload will be encrypted, using any method, at the application layer then re- 2545 encrypted at the MAC layer using the specified default LoRaWAN encryption 2546 Corrected FHDR field size typo 2547 Corrected the channels impacted by ChMask when ChMaskCntl equals 6 or 7 in 2548 7.2.5 2549 Clarified 6.2.5 sentence describing the RX1 slot DataRate offset in the JoinResp 2550 frame 2551 Removed the second half of the DRoffset table in 7.2.7 , as DR>4 will never be 2552 used for uplinks by definition 2553 Removed explicit duty cycle limitation implementation in the EU868 MHz ISM band 2554 (Section 7.1) 2555 Made the RXtimingSetupAns and RXParamSetupAns sticky MAC commands to 2556 avoid end-device's hidden state problem. (in 5.4 and 5.7) 2557 Added a frequency plan for the Chinese 470–510 MHz metering band 2558 Added a frequency plan for the Australian 915–928 MHz ISM band 2559 17.3 Revision 1.0.2 2560 Extracted Section 7 "Physical layer" that will now be a separate "LoRaWAN regional 2561 physical layers definition" document 2562 corrected the ADR backoff sequence description (ADR_ACK_LIMIT was written 2563 instead of ADR_ACK_DELAY) paragraph 4.3.1.1 2564 Corrected a formatting issue in the title of Section 18.2 (previously Section 19.2 in 2565 the 1.0.1 version) 2566 Added the DlChannelRec MAC command, this command is used to modify the 2567 frequency at which an end-device expects a downlink. 2568 Added the TXParamSetupRec MAC command. This command enables to remotely 2569 modify the maximum TX dwell time and the maximum radio TX power of an end- 2570 device in certain regions 2571 Added the ability for the end-device to process several ADRreq commands in a 2572 single block in 5.2 2573 Clarified AppKey definition 2574 2575
