Dialup UK Article - Evolution Of Dialup Internet Access
Dialup access is a form of Internet access in which the user
a modem connected to a computer and the ordinary telephone
line to dial into an Internet service provider’s computer.
This process establishes a link that is then transferred to
the Internet. Dialup requires no additional equipment other
then a computer, modem and the telephone network connection.
As telephone points are easily available in homes and offices
throughout the world, dialup connections remains most used
Internet access option. It is also the oldest method of internet
Dialup technology dates back over a century. The evolution
of dial up technology has gone through many twists and turns
before coming in its present form. Its origins back to the
days of the development of the telegraph in the 19th century.
In those days, electronic signals were sent across an extended
circuit. These signals were created manually by tapping contacts
together to in a specific form of on or off. The first step
in evolution came when Alexander Graham Bell invented the
telephone in 1875. This revolutionary invention changed communication
forever. The telecommunication service was improved dramatically.
Once, the capability to send a voice across the line was achieved,
the technology was more accessible to consumers.
In the beginning of the 20th century, this technology was
spread throughout United States. The technology evolved further
due to demand for the improvement in service and potential
commercial exploits drove technological innovations further.
Other innovations along the way included International telephonic
services and microwave stations that started in Unites states
in 1940’s and 1950’s connecting American cities.
Integrated digital networks were innovated. First of the communication
satellites went into service in 1960’s to improve the
quality and span of telephonic service further. By end 1970’s,
a large number of the home and commercial users in developed
countries were connected through telephone service. This is
when the modem was born and introduced in the service starting
the final phase of revolution in the history of the dialup
The early modems were slower and limited to smaller communication
networks. Early uses of modems were for sporadic LAN (Local
Area Network) and WAN (Wide Area Network) connections. The
call would come into a regular phone at a data center. An
operator would listen to modem tones and place the handset
onto a special cradle of the equipment called a modem. The
introduction of Internet in the early 1980’s and its
spread in late 1980’s and 1990’s gave tremendous
boost to the modem and dialup connection technology.
Modern dialup modems typically have a maximum theoretical
speed of 56 kbps. Although. In reality, in most cases only
up to 48 to 53 kbps can be achedived due to various limitations.
This speed is currently considered the maximum possible in
case of a dial up connection. In many cases, transfer speeds
will be even lower averaging around 30kbps to 40 kbps. This
happens due to poor quality equipment and other factors such
as phone line noise. Quality of modem also plays a large part
in determining connection speeds. Nevertheless, the dialup
connection remains most used mode of internet access in the
