latency during video meetings

[saidfarah]

It has been reported that there is latency and bad reception during video meetings with 5 participants. I believe the participants use wireless to access the meetings.  Other employees not in the meeting use wireless network, during above time. How can empirical data be generated to find the cause and severity of the network latency during the video meetings?

Thank you.

I wish I could day click here and click there and sprinkle a little pixie dust and shazam problem identified and solved. 

Here is what I would do:

1) See the problem for yourself and if you can reproduce it then you are in a good spot troubleshooting wise

2) If you are having issues try and see if its a specific device(s). Compare with other devices.

3) I then like to look at client debugs. Looks for odd behavior; client trying to roam. 

4) Whats the channel utilization look like. Thats usually a low hanging fruit you can look at.

5) I also like to sniff the client traffic. You can see first hand what is going on.

make sure of the below :

RSSI > -67 ,

SNR > 25

no interference

no channel utilization , 

WMM is enabled

encryption is AES 

low data rates disabled .

QoS profile of that WLAN is gold or platinum

 Hello,

 There are so many reasons why this could be happening, from noise and interference to way to many people connecting to the same access point a bottle neck on the wired portion of the network, old encryption on the device or devices  been used, lower data rates enabled...

 I will suggest you to begin by confirming if it is possible to replicate the issue on demand in deed, if that is the case, then you may verifying the health of the wireless network, whatever platforms you have, as others mentioned: rssid, snr, channel assignment and utilization, tx power and so on,

Regards.
