Cisco Wireless Deployment High Density

[ivan.martin]

Hi my name is Ivan

I have a question

We need to work a network with high performance data applications, voice and video for a University. We have done tests with a user downloading files 4GB and simultaneous video calls with skype, and we note that the video quality is degraded, as well as the file is cutting and canceling the download, as we mobilize for campus. 

We would like to know if the problem coexists in performance or coverage or both. 

To what extent we can tune the configuration of the Cisco WLC for better service delivery. 

Any recommendation please 

Thank you. 

Ivan

Not enough information.  

1.  When the video calls was on-going, what radio was this being carried over? 

2.  What is the model of your WLC? 

3.  What is the model of your AP?

4.  What is the firmware of the WLC? 

5.  Did you check for co-channel interferrence? 

6.  What is the speed of the APs wired Ethernet link?

7.  Did you check for speed/duplex issues of the wired Ethernet link? 

8.  What is the LAN backbone speed from the switch up to the WLC? 

9.  When doing the video calls, how many clients were associated to this AP?

We have  tested with  one user, using video calls, downloading of 4GB, sharing files by wireless network, and the conectivity is too long

Thanks for your answer.

I'd look into doing a video call with only ONE person per AP at either end.  No roaming. 

See if see any improvements.

Post the output to the command "sh wlan <ID>".
