Using an IEEE 802.11 protocol analyzer, you have determined that the retransmission rate is higher than your baseline. What further troubleshooting step can an administrator take to determine if the retransmissions are negatively affecting the wVoIP receiver?
A.
Place a spectrum analyzer near the receiver and look for high signal strength dashes placed horizontally across the swept spectrogram.
B.
Manually increase the jitter buffer on the receiving wVoIP device to see if the voice quality changes.
C.
Using a wVoIP protocol analyzer, set a one-way filter on the MAC address of the wVoIP receiver and look at the delta time between arriving frames.
D.
Monitor the WIPS for Head-of-Line blocking at the wVoIP receiver.
E.
In the wVoIP VLAN, modify the AC from AC_VO to AC_BE to see if the problem is QoS-centric or RF-related.
F.
Configure two wVoIP phones identically except for channel assignment, then compare retransmission count values.
