Hey Brett,
 
Thanks for your reply. What height and what radios are you using ?
 
All: Everything else being equal can the range change if we are using infrastructure or adhoc mode ?
 
I would be interested in plugging madwifi to get XR feature but would need some direction.
 
Thanks,
Jaideep

I am doing some madwifi testing with XR2 radios and madwifi trunk. I would appreciate if you can share your comments on the questions below.

 

  1. What distance can I expect with good line of sight, respectable height, 29Db gain grid antennas and XR2 (high power) radios using madwifi trunk ?
  2. Does it change if I am in adhoc mode instead of infrastructure mode ?
  3. What parameters do I need to tweak to get the max distance ?
  4. Do we support UBNT XR features in madwifi trunk ?

Please note that I have already read http://madwifi-project.org/wiki/UserDocs/LongDistance and other related links. I am looking for practioners perspective or battlefield status.

 

Regards,

Jaideep
