Electronic communications data should be defined in a sufficiently broad and technology neutral way so as to encompass any information concerning the content transmitted or exchanged (electronic communications content) and the information concerning an end-user of electronic communications services processed for the purposes of transmitting, distributing or enabling the exchange of electronic communications content; including data to trace and identify the source and destination of a communication, geographical location and the date, time, duration and the type of communication. Whether such signals and the related data are conveyed by wire, radio, optical or electromagnetic means, including satellite networks, cable networks, fixed (circuit- and packet-switched, including internet) and mobile terrestrial networks, electricity cable systems, the data related to such signals should be considered as electronic communications metadata and therefore be subject to the provisions of this Regulation. Electronic communications metadata may include information that is part of the subscription to the service when such information is processed for the purposes of transmitting, distributing or exchanging electronic communications content.
