Some wifi wardriving

Modified my Wi-Spy or as we call him "Wifi Spray" to allow external antennas to be connected. First tests were made right at home. First image is about traffic in air with two accesspoints. AP on channel 1 make copying of big files while AP on channel 9 does some usual surfing activity.
This is good explanation why it is not good idea to have different wifi accesspoints on nearby channels.

Another really good this is to know on which channel your microwave over works. My accesspoint was previously somewhere on 13-th channel. After seeing next picture I moved it to first:

Similar picture got near house about visible two accesspoints:

Even from longer distance, accesspoint makes lot of interference on channels around it.

Some alien data was captured also and visible here:

So clean transmission on channel 1. Meanwhile window down can identify accesspoint on channel 11 only. Can someone propose, what is that on channel 1? BTW, those yellow and red dots are generated by my own wifi network cards which is querying for available accesspoints. If I switch it off, this noise disappears.
