From 8 July, TfL have been tracking passenger movements using the Underground’s Wi-Fi system and mobile phones, to gain data on how the transport network is being used. It has been reported that the system will track a mobile phone and provide the relevant data, even if the phone is not connected to the Wi-Fi network. Can you confirm whether that is correct?
