So the signal between the antenna and the receiver (gateway) is blocked by the metal. This will greatly reduce the signal. In such case, we can consider using antenna extend cable to extend the antenna to a better position. 100 - 101 - 102 102 = Some real-world case = 103 103 104 104 == Server reason cause end node has problem on Join. ==
