Mobile is a rapidly growing and potentially major element of the future Internet, and its environment cannot be sensibly considered in isolation from fixed networks. A note on terminology: Europe uses the term Mobile Network Operators (MNOs) while the United States uses ‘wireless’ Internet Service Providers (ISPs). ‘Wireless’ is somewhat more open in the United States. In Europe, mobile has always made special pleading for forms of self-regulation, as we will see.
