How do you locate me without an active wifi connection?
I live in Japan and got an ipod touch lately. I've noticed it often that I could locate myself without establishing any wifi connections. How do you make this happen? Do I have off-line database of well-known MAC addresses in ipod touch just like PlaceEngine does?

Inappropriate?The way this technology works on the iPod touch is it needs to be connected to Wi-Fi to query the database and get a location. The iPhone performs this query over the cellular data network and does not require you to have an active Wi-Fi like the iPod touch.
Currently there is no off line database for our positioning system. Our database is extremely huge and would not fit on a small device.

Okay. That makes sense. I guess the connection was established without showing any obvious sign on my ipod touch. Thanks for the clarification.
