Everything about Internet Access totally explained
Internet access refers to the means by which users connect to the
Internet.
Common methods of internet access include
dial-up, landline (over
coaxial cable,
fiber optic or
copper wires),
T- lines,
Wi-Fi,
satellite and
cell phones.
Public places to use the Internet include
libraries and
Internet cafes, where computers with Internet connections are available. Some libraries provide stations that provide facilities for hooking up public-owned laptops to
local area networks (LANs). There are also wireless Internet access points in many public places like airport halls, in some cases just for brief use while standing. These Access points may provide coin operated computers or
Wi-Fi hot spots* that enable specially equipped laptops to pick up internet service signals. Various terms are used, such as "public
Internet kiosk", "public access terminal", and "Web
payphone". Many hotels now also have public terminals, though these are usually fee based.
- Wi-Fi provides wireless access to computer networks, and therefore can do so to the Internet itself. Hotspots providing such access include Wi-Fi-cafes, where a would-be user needs to bring their own wireless-enabled devices such as a laptop or PDA. These services may be free to all, free to customers only, or fee-based. A hotspot need not be limited to a confined location. The whole campus or park, or even the entire city can be enabled. Grassroots efforts have led to wireless community networks.
Apart from Wi-Fi, there have been experiments with proprietary mobile wireless networks like
Ricochet, various high-speed data services over cellular or mobile phone networks, and fixed wireless services. These services have not enjoyed widespread success due to their high cost of deployment, which is passed on to users in high usage fees. New wireless technologies such as
WiMAX have the potential to alleviate these concerns and enable simple and cost effective deployment of
metropolitan area networks covering large, urban areas. There is a growing trend towards wireless
mesh networks, which offer a decentralized and redundant infrastructure and are often considered the future of the Internet.
Broadband access over power lines was approved in 2004 in the United States in the face of stiff resistance from the
amateur radio community. The problem with modulating a carrier signal below 100 MHz onto power lines is that an above-ground power line can act as a giant antenna and jam long-distance radio frequencies used by amateurs, seafarers and others. A recent discovery, called "E-Line" allows propagating much higher frequency carriers, from 100 MHz through at least 10 GHz, onto a single conductor of a power line and offers the possibility of very high speed fixed and mobile information services at very low cost without the problems associated with the lower frequency signals.
The use of the Internet around the world has been growing rapidly over the last decade, although the growth rate seems to have slowed somewhat after
2000. The phase of rapid growth is ending in industrialized countries, as usage becomes ubiquitous there, but the spread continues in
Africa,
Latin America, the
Caribbean and the
Middle East. One example of a great number of people gaining access to the internet is in
Brazil, thanks to lowering taxes on computers and in dial-up providers, Brazilians are growing significantly on the internet in the past 2 years.
Countries where Internet access is available to the majority of the population
Asia
North America
South America
Europe
Africa
Oceania
However, there are still problems for many. ADSL and other broadband access are rare or nonexistent in most developing countries. Even in developed countries, high prices, mediocre performance and access restrictions often limit its uptake. Within individual countries, wide differences may exist between larger cities (often having multiple providers of broadband access) and some rural areas, where no broadband access may be available at all.
The expansion of the availability of Internet access is a way to bridge the "digital divide".
Internet access as a human right
Today, there's a big push by the United Nations to make internet access a human right. This push was made when it called for universal access to basic communication and information services at the UN Administrative Committee on Coordination. In 2003, during the World Summit on the Information Society, another claim for this was made.
In some countries such as Estonia and Greece, internet access has already been made a human right.
