Using a portable analyzer you perform a packet capture next to a client STA and you can see that the STA is associated to a BSS. You observe the STA sending packets to the AP and the AP sending packets to the STA.
Less the 2% of all packets are retransmissions. You move to capture packets by the AP and, while the retry rate is still very low, you now only see unidirectional traffic from the AP to the client. How do you explain this behavior?

• A.The STA is transmitting data using more spatial streams than the potable analyzer can support
• B.The portable analyzer is too close to the AP causing CCI, blinding the AP to the client's packets
• C.There is a transmit power mismatch between the client and the AP and while the client can hear the Aps traffic, the AP cannot hear the client.
• D.The portable analyzer has a lower receive sensitivity than the AP and while it can't capture the packets from the client STA, the AP can receive them OK.
