437 437  
438 -1. It only supports LoRa radio with fix frequency, fix DR (Spreading Factor) , Fix bandwidth and
439 -1. This method only support uplinks. It doesn;t work for LoRaWAN Downlink.
440 -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).
