Typos and clarification
StreetPass in sleepmode can work without SD card inserted. Games' Streetpass data are temporarily stored in NAND, and when the games process the StreetPass data they move that data to extdata on SD card.

Whenever the 3DS is woken from sleep (or turned on), and WiFi is enabled, it sends out a 802.11 Probe Request which include all saved access points, as well as to an SSID containing an arbitrary string of data, such as "ic[kSvm9s@*cYD>/~IEVj\(fGG;qDo8j". The latter probe may be related to the 3DS looking for Nintendo Zone APs. This string changes at least daily, and most likely every time it is woken up.

The MAC address used for these probes are the static MAC address found in the Settings application. Unlike the StreetPass MAC address, it will not change over time. This MAC address OUI also differs from the one used in StreetPass.
