iPhones are very "chatty" when not connected to a WiFi access point. They repeatedly try to find access points they have connected to before - broadcasting both their MAC address and the SSID of prior access points.
Android phones are completely silent even with the WiFi on when not connected to an access point.
- voltagex_ 13y agoI don't think they'll be silent any more unless you turn off 4.3's "Allow scanning by services" option.
- sangnoir 13y agoThey'll still be silent: "Allow scanning by services" is listen-only with no transmission.
