AC Transit wifi

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

Seems to me if you lived along a bus route, you might not want to use
channel 1, assuming all buses are on that channel.

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.
