Introduction to broad band services in India.
Internet in India, implemented first in the year 1986 only for education field or community and later in the year 1995 it was implemented in all communities. First, let us see what is broadband before knowing the broadband services in India.
What is broadband?
Broadband means the transmission of data over a high speed internet connection through multiple types of technologies. This data which is transmitted over internet is wide bandwidth data which includes multiple signals and traffic types. The medium that is used for transmission can be coaxial cable, optical fibre, radio or twisted pair. When compared to traditional analog or ISDN and dial up access the speed transmission of data over broadband is very fast.
Types of broadband
Broadband is generally transmitted through high speed transmission technologies and factors. The technologies that are included are:
- CABLE MODEM
The factors that are considered for providing broadband services are:
- location or place of living whether in urban or local place
- packages such as voice telephone and home entertainment
DSL (Digital Subscriber Line)
DSL is a technology that implements wireline process that transmits data very fast over traditional copper telephone lines whether it may be home or business. It provides speeds ranging from several hundreds kbps to millions bits per second and depends upon on the distance from home or office and nearest telephone company facility. The technologies that are implemented in DSL are:
ADSL: ADSL means asymmetrical digital subscriber line used by residential customers mostly who do surfing and searching a lot when compared to data sending thus it provides faster downstream data transmission over the same telephone line.
SDSL: symmetrical digital subscriber line used by businesses which is mainly used for video conferencing and meetings where bandwidth for both upstream and downstream transmissions is done equally. There are two types in SDSL one is HDSL high data rate subscriber line and VDSL very high data rate digital subscriber line are also implemented in business depending upon the requirement.
This is the broadband service that is provided using coaxial cables that have two connections one to the cable wall and the other to a computer. The transmission speed provided through this will be 1.5Mbps and more which can be accessed very easily just by turning on the computers and the speed may differ depending upon the traffic load compared to DSL
In fiber optic technology, electrical signals are converted which carries data to light and transmits the light through transparent fibers which has the diameter similar to human hair. Fiber transmits data far more speed compare to DSL or cable modem speeds. It depends on many factors like the distance between your computer and service provider and its configuration and the amount of bandwidth that is distributed for deleting video services and video in demand and other services.
This type of service connects home or business to the internet using radio link between the home or office location and the provider’s facility. It can be mobile or fixed which uses longer range broadband service using external antenna. Wireless internet service provider’s provides services often implemented in rural areas. Mobile wireless broadband services are also available for mobiles which provides limited speed. WLAN wireless local area network provide wireless broadband services over short distances and which is implemented as hotspots where internet is available in public areas such as restaurants, coffee shops and others.
Satellite broadband is another form of wireless broadband which depends on several factor for transmission of data like weather and satellite orbiting position for downstream and upstream speeds.
BPL (Broadband Over Powerline)
This is the broadband service provided through the low and medium voltage distribution network which provides cable and modem speeds but it is available in limited areas.
What is broadband speed?
Broadband speed is usually required for streaming HD videos ,gaming and to download large files as well as to upload, streaming music, surfing internet and for office activities like arranging video conferencing and others. Different packages provided by different broadband providers have different speed plans up to 100mbps and above.
In India, irrespective of location you live whether in city or rural areas many multiple of broadband providers are there which provide multiple plans or packages which differ one from the other in factors like speed and location. The best broadband providers in India are reliance JIO, Airtel, Vodafone and BSNL and many other providers but one should follow few steps or measures to choose the best broadband service provider:
