Hi sandeep,
I never used wifi just like you. So I only have
some advices for you.1. Video needs more
throughput, so 7:3 or 8:2 seams better.2. If you
use RTSP to transmit video, I guess you can short the
switch
time to reduce the delay. Just try to set period to
100ms or less for test. I think it will be
better.

a wifi client to Linksys. I have a development board in
which i have AR9287 as the Wifi chipset associated as wifi
client to linksys. The development board has Bluetooth
dongle for streaming audio etc. The development board has
a
LCD display and I stream the video stream from camera at
640
x 480 resolution, MPEG-4, 10fps (also tried with 15, 30
fps).

I am using the ath9k driver with btcoex_enable=1.

Bluetooth an 60% of the time for WiFi. The period is
around
200ms.
