It is probably the difference between passive vs active scanning. To save time and consequently power, most battery powered wifi devices use active scanning where the station sends a probe request and expects to get a probe response from the AP (or beaconing device). Typical dwell times in active scanning are 20-40ms / channel while passive (listen only) scans are usually more like 110 ms / channel, since the default beacon interval of many APs is 100ms. If you have linux on your laptop, you might try 'iw wlan0 scan freq $FREQ passive' Jason _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
