The term broadband refers to a
telecommunication bandwidth that is at least 256 Kbps. A single broadband
communication channel is 6 MHz wide and the voice grade is greater than 20 KHz.
Broadband uses a wide range of frequencies to seamlessly transmit and receive
information between networks. Broadband offers more speed than a traditional
dial up internet connection because data and information can be multiplexed and
transmitted on different communication frequencies and channels.
Many years of ground breaking
research, effort and patience contributed to the invention of broadband in the
new millennium. Standards, technical specifications and protocols were put in
place by international unions and major telecom companies throughout the world
started offering broadband services at 256 Kbps to home consumers, institutions
and business enterprises. In a short span of twelve years the broadband speeds
have gone from a meager 256 Kbps to an incredible 10 Mbps. Broadband has
tremendously enhanced the growth of the world wide web and consumer
applications, scripts and enterprise software are becoming more available to
the public.
There are five different types of
broadband connections. They are DSL broadband, cable broadband, wireless
broadband, satellite broadband and power line broadband. DSL is the
abbreviation for Digital Subscriber Lines. DSL is a wired broadband technology that
effortlessly relays and receives data and information over conventional
telephone lines. Since everyone has a landline at home, DSL is easy to install
and it can provide transmission speeds of up to 1 Mbps. Airtel provides DSL
services. The speed of the DSL connection varies depending on the quality of
the telephone line and the distance of the telecom company from your home.
There are four different types of
DSL. They are ADSL, SDSL, HDSL and VDSL. ADSL stands for Asymmetrical Digital
Subscribers Line. ADSL technology is developed primarily for the residential
market and for people who download more information than upload. ADSL gives
more speeds in the downlink and very low speeds for the uplink without
affecting the regular voice calls in the telephone. SDSL is the acronym for
Symmetrical Digital Subscribers Line. SDSL is used by corporates and business
people for value added services like web conferencing that requires rich
bandwidth. HDSL means High data rate Digital Subscribers Line. VDSL stands for
Very high data rate Digital Subscribers Line. Both these technologies are used
by corporates for special and advanced bandwidth requirements.
Cable modem is a broadband
technology that enables television operators to provide internet connectivity
using coaxial cables. You don’t need to dial up your internet service provider
and this connection is always on. Hathway provides broadband using cable modem.
Wireless broadband is based on the 4G technology that uses a radio link to
connect the consumer to the internet service provider. They use long range
directional devices to seamlessly transmit and receive information between
routers. Tikona Digital Networks provides 4G wireless broadband services. Satellite
broadband uses orbiting satellites to relay and receive information in sparsely
populated cities. Power lines are recently used to provide broadband
connectivity using the electric power distribution network. Broadband is an
amazing telecommunications technology that has changed the internet landscape
and promises a bright future for net enthusiasts.
