The wide band originally referred to an
access to Internet access than analogue (56kbps dial in a basic or 128
kbps in basic access ISDN). The concept has changed over time in
parallel with technological developments. According to the Federal
Communications Commission in the U.S. (FCC) is considered as broadband access
at speeds equal to or greater than 200 kbps in at least one direction. For
the International Telecommunication Union is at the threshold of 2 Mbps.
Depending on the country, there are different
technologies: the so-called FTTH (fiber to the home), cable (introduced
in principle by TV broadcasting), satellite, ISDN (supported by the
traditional telephone network) and others being development.
The
development model of connectivity in each country is different and the
decisions of regulators in each country have led to different market
structures.The figure is the evolution of Internet access from 1999 to 2007 and
you can see how that period increased use of broadband.
Internet is evolving very rapidly and greatly
increasing the amount of heavy content (videos, music ...). For this
reason, operators are finding in many cases than traditional networks have
insufficient capacity to support adequate levels of quality traffic that is
beginning to generate and expect the problem to increase over time due to the
current rate of growth. Some operators in countries of the Organization
for Economic Cooperation and Development ( OECD ) are upgrading their
networks, bringing fiber to the home (FTTH-Fiber-to-the-home) and fiber to the
building (FTTB, Fiber-to- the-building). In December 2007, the number of
accesses to broadband via fiber and an assumed 9% of total OECD countries, one
percentage point from a year earlier. The ADSL technology remained the implode
with 60% of broadband lines and the cable holding the second position with 29%.
This development of the technology of optical
fiber is not uniform across countries of the OECD. In Japan and South
Korea takes 44.5% and 39.2% of broadband connections respectively with
this technology, after the spectacular growth of 14.5 points and 15 percentage
points respectively in a year and a half, absorb virtually all the growth of
this technology, in Europe, with 1% of the connections, just start the renewal
of current technology for fiber optics.
In 2007, in the countries of the European Union the
percentage of DSL lines over the total broadband accesses stood at 80.3%. Play
for technology xDSL deployment costs and the development of ADSL 2 +,
higher capacity and supply.
The reasons for preferring broadband connections are
not having the phone line busy, the speed of access and the ability to stay
connected. And access to new services related to photography, downloading
music or videos.
