Acessing the Internet

The Net connections can be based on wire-line and wireless access technolgies.

Wire-line access

Wire-less access

copper wires

Satellites

coaxial cables

mobile terrestrial antennas

electric power lines

fixed terrestrial antennas

fiber-optic cables







Usually several kinds of network connections are employed at once. Generally speaking, when an E-mail message is sent it travels from the user's computer via copper wires or coaxial cables ISDN lines, etc., to an Internet Service Provider, from there, via fibre-optic cables, to the nearest Internet exchange, and on into a backbone network, tunneling across the continent und diving through submarine fibre-optic cables across the Atlantic to another Internet exchange, from there, via another backbone network and across another regional network to the Internet Service Provider of the supposed message recipient, from there via cables and wires of different bandwidth arriving at its destination, a workstation permanently connected to the Internet. Finally a sound or flashing icon informs your virtual neighbor that a new message has arrived.

Satellite communication

Although facing competition from fiber-optic cables as cost-effective solutions for broadband data transmission services, the space industry is gaining increasing importance in global communications. As computing, telephony, and audiovisual technologies converge, new wireless technologies are rapidly deployed occupying an increasing market share and accelerating the construction of high-speed networks.

Privatization of satellite communication

Until recently transnational satellite communication was provided exclusively by intergovernmental organizations as Intelsat, Intersputnik and Inmarsat.

Scheduled privatization of intergovernmental satellite consortia:

Inmarsat

1979

158 nations (all members of the International Maritime Organization)

privatized since 1999

Eutelsat

1985

Nearly 50 European nations

2001



When Intelsat began to accumulate losses because of management failures and the increasing market share of fiber-optic cables, this organizational scheme came under attack. Lead by the USA, the Western industrialized countries successfully pressed for the privatization of all satellite consortia they are members of and for competition by private carriers.

As of February 2000, there are 2680 satellites in service. Within the next four years a few hundred will be added by the new private satellite systems. Most of these systems will be so-called Low Earth Orbit satellite systems, which are capable of providing global mobile data services on a high-speed level at low cost.

Because of such technological improvements and increasing competition, experts expect satellite-based broadband communication to be as common, cheap, and ubiquitous as satellite TV today within the next five or ten years.

Conservative vs. Progressive Think Tanks

The political orientation of think tanks is as broad as in every other kind of institutions or organizations. It ranges from conservative over centrist to progressive. Still it can be noted, that there are considerable differences between the right and the left wing of think tanks, especially concerning funding sources and revenues as well as media relations, which have considerable consequences on their perception and influence on the public as well as on policy makers.

Citizens for Tax Justice

Citizens for Tax Justice was formed in 1979 to give people a "greater voice" in the development of the tax laws at the national, state and local levels. CTJ efforts are based on the idea that people should pay taxes according to their ability to pay them.

Neighboring rights

Copyright laws generally provide for three kinds of neighboring rights: 1) the rights of performing artists in their performances, 2) the rights of producers of phonograms in their phonograms, and 3) the rights of broadcasting organizations in their radio and television programs. Neighboring rights attempt to protect those who assist intellectual creators to communicate their message and to disseminate their works to the public at large.

Citizens for a Sound Economy

Since 1984, Citizens for a Sound Economy has advocated market-based solutions to public policy problems. Uniting its 250,000 members is the fundamental belief that a strong and vibrant free-market economic system offers the best hope for creating opportunity and improving the quality of life for every American.

Economic Policy Institute

EPI was founded to "widen the debate about policies to achieve healthy economic growth, prosperity, and opportunity in the "new American economy"." Areas of research include political issues, economic issues, industry policy, social issues, education and environmental issues. EPI's current research agenda includes projects on: evaluating state/federal minimum wage policies; welfare reform; social security studies; domestic industrial competitiveness; nonstandard work arrangements; "fast-track" and other globalization policies; and privatization of public services.
