  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.
  > 2-wire coexistence. I am allowing 40% of the time for
  Bluetooth an 60% of the time for WiFi. The period is
 around
  200ms.
