Re: switch off your Wi-Fi...

Device initiates. If you want your device to be untrackable*, you need to switch off WiFi. I think there are some ways to randomise the MAC address periodically to reduce the problem but you can bet lots of places do this.

*By WiFi traffic analysis I mean. It's still going to be broadcasting on its 4G frequency.
