What is Broadband?
Broadband comes from the words "broad bandwidth" and is used to describe
a high-capacity, high-speed, two-way telecommunication link between an end
user and access network suppliers capable of supporting & providing the
transmission multiple channels of data simultaneously over a single communications
medium. Most connections are ADSL Broadband or Cable Broadband. Other technologies
for receiving broadband are also available, such as satellite, mobile, radio,
digital TV and fibre technologies.
In layman's terms, If you are currently using a dial up connection via modem
the easiest way to understand broadband is that its basically very similar
but MUCH faster, offering greater flexibility & pleasure it use of the
world wide web known as The Internet.
ADSL Broadband
Broadband 'splits' the telephone line so that both voice and data can be transmitted
along one line. This is done in the home via a broadband modem and filters,
and at the telephone exchange for ADSL broadband or at the cable network for
cable broadband.
ADSL broadband connects you to the Internet via a BT line and the local BT
phone exchange.
Broadband ADSL (Asymmetric Digital Subscriber Line) is a type of DSL. It works
by splitting your existing telephone line signal into two, voice and data
can be transmitted along one line. Upload speeds are different, in fact always
less than the download speeds hence this is why it is "asymmetric".
SDSL Broadband
SDSL Broadband (Symmetric Digital Subscriber Line), An improved version of
DSL is where the technology provides the same bandwidth in both directions
where the upload speeds (upstream) and download speeds (downstream) are the
same, over existing copper telephone lines. Hence, Symmetric.
What is DSL?
DSL (Digital Subscriber Line) is a technology, family of digital telecommunications
protocols, designed to allow & bring high speed data communication / high-bandwidth
information to homes and small businesses over the existing copper telephone
lines between end-users and telephone companies.
Cable Broadband
Cable Broadband provides users high speed Internet access through a cable line
without using a telephone lines. Packages can also offer home telephone and
digital cable television.
Satellite Broadband
Satellite Broadband offers two-way Internet access via satellites. Your computer,
through a special satellite modem, broadcasts requests to a satellite dish
that sits on top of your home or business premises. The dish then sends and
receives signals from satellites that orbit some 22,000 miles above the earth.
Currently, satellite broadband is slower in both the uplink and downlink,
when compared to a DSL Internet services such as ADSL & SDSL as well as
being much slower than Cable Broadband.
Wireless Broadband
Wireless Broadband offers a wonderful convenience & flexibility of use
of your broadband connection, it supplements some existing broadband provider
packages whether ADSL or Cable Broadband.
A wireless LAN or WLAN is a "Wireless Local Area Network" that uses
radio waves as its carrier: the last link with the users is wireless, to give
a network connection to all users in the surrounding area. Areas may range
from a single room in your home to an entire campus or business premises.
The backbone network usually uses cables, with one or more wireless access
points connecting the wireless users to the wired network. The beauty is freedom
to roam with the field of the signal strength, like sitting in your garden
on a sunny day or any room in your home, as well as allowing multiple users
to access simultaneously.
