| 20 | | Since there is no way to put a matching antenna on BasicTX/BasicRX, the two BasicTX/BasicRX daughterboard are connected through two wires, which means the waveform transmitted from BasicTX to BasicRX doesn’t go through air but the two wires. For right now, the TX_B port of the BasicTX on node1-1 is wired to the RX_B on the BasicRX on node1-2, and the the TX_A of the BasicTX on node1-1 is wired to the RX_B on the BasicRX mounted on node1-2. Therefore, make sure you have node1-1 as the transmitter and have node 1-2 be the receiver. |

| | 20 | The image above shows TX_A connected to RX_B through a 50 ohm attenuator. Likewise, side B of both nodes are connected through an attenuator. The ports are connected through wires in order to minimize noise. However, both TX and RX can use actual antenna. |
