 signalling advances is being applied at the levels of protocols for switching (for secure packet switching). However, expansion in economic trade over these new networks with e-commerce will also open the telecommunications infrastructure to various forms of attack. Mobile will offer more than communications, with multimedia content as well as satellite positioning and cell-based location services. New directions in mobile will develop with the commercial and medical/care uses of INFRASTRUCTURE TO 2030: TELECOM, LAND TRANSPORT, WATER AND ELECTRICITY - ISBN 92-64-02398-4 © OECD 2006 2. TELECOMS INFRASTRUCTURE TO 2030 RFID (radio frequency identification) technology and new infrastructures may be built to handle these, as in the Korean port of Busan. Other novel technologies, such as nanotechnology for building parts of handsets, especially motive power, may be useful. Innovative energy technologies - specifically battery technologies for mobile handsets, with polymer composites having higher power densities - will be important. Local energy technologies such as solar and wind power will be required for remote networking. Space technologies, especially for lower-cost highly reliable launches might give rise to fleets of low earth orbit (LEO) satellites - which would have to change the basics of the failed business models of the first generation of LEOs (Iridium, Teledesic, etc.). The result would be a low-cost satellite infrastructure for developing regions and dense urban areas. At the social and industry level, availability of a new generation of ubiquitous radio-packet broadband will change other infrastructure elements; through teleworking perhaps, RFID will change logistics and medical/care infrastructure services. Public decision-making process and telecommunications regulation What is considered in the public interest in telecommunications has changed over the past two decades. Liberalisation and democratisation has had enormous influence over the ownership, structuring and operation of telecommunications n
