Hi everyone,<br>
We are trying to measure the Effective Isotropic Radiated
Power(EIRP) of few prism3 based compact flash wireless cards running on
an embedded target with hostap 0.3.8. For this purpose we need to have
the cards transmitting without being associated to an access point.
Probe requests sent as part of an active scan should be sufficient.<br>
<br>
If I use the 'iwlist wlan0 scan' command, does the card firmware
perform an active scan with probe requests or does it simply perform a
passive scan of the values already obtained from AP beacons? <br>
<br>
>From the hostap README, I came to know of the 'iwpriv wlan0 host_scan
<x>' command which performs an active scan. Does this work even
in the default firmware roaming mode?<br>
<br>
Also, is there a way I can restrict the active scan to be performed only in one channel at a time? Please let me know.<br>
<br>
Thank you,<br>
Sriram C.<br>
