I'm not really sure what possessed me to sniff the wifi from the local AC Transit buses with my phone today, but here is the info:
SSID: 5122 Mac Address: 00:0E:8E:2F:CE:84 Encryption: WPA2 Personal Channel: 1 Signal Strength:-68 dbm Band: 802.11b/g Signal Level: 36%
SSID: 4014 Mac Address: 00:0E:8E:2C:25:EC Encryption: WPA2 Personal Channel: 1 Signal Strength:-76 dbm Band: 802.11b/g Signal Level: 23%
The buses were about a 600ft away and about 40ft lower in altitude. It turns out the SSID is the bus number. You can read the number on the top of the bus. I guess the signal level is more like the quality that typical wifi gear reports. I wouldn't expect it to be good outside the bus.
The mac comes back to Sparklan >
Now checking the AC transit website, the wifi is supposed to be open:
Maybe they use wifi for something else since these WAPs are encrypted.
