3 Repeaters 1781
1782
Repeaters have not yet been specified by the LoRa Alliance; however, this specification does 1783
include references to repeaters and constraints that end-devices should follow to be compliant 1784
with them. 1785
3.1 Repeater Compatible Maximum Payload Size 1786
Repeaters, as referenced in this specification, were intended to fully encapsulate a 1787
MACPayload in the ApplicationPayload of another LoRaWAN data message. In addition 1788
to the original MACPayload, up to 20 bytes of metadata describing the original message were 1789
envisioned to be included with the encapsulated data message. In order to minimize impact 1790
on the end-device and its application, repeaters would communicate with the network 1791
(gateways) using only data rates that supported the maximum allowed MACPayload size of 1792
250 bytes. Therefore, these data rates show a maximum payload size that is 20 bytes fewer 1793
when describing "Repeater Compatible" operation. 1794
