437 +== 7.3 Limited of using LA66 as relay of LoRaWAN ==
438 +
439 +LA66 is a LoRa End Node module base on SX1262 core. Use it as relay as mentioned above has below limitation:
440 +
441 +1. It only supports LoRa radio with fix frequency, fix DR (Spreading Factor) , Fix bandwidth and
442 +1. This method only support uplinks. It doesn;t work for LoRaWAN Downlink.
443 +1. Capacity depends on how often the end nodes sends send uplinks. The LA66 needs to spends around 1~~3 seconds to relay one packet ( depends on DR. inlcudes RX and TX time).
