Definition:
Broadband is a communication carriers or media. With broadband, multiple signals can travel on the same media at the same time.
What exactly broadband?
Communication carriers or media, for example wires or cables,
are of two types: broadband and base band . Base-band is where only one signal passes through the media at a time. So, with broad band, multiple signals can travel on the same media at the same time. The classic example of this is the cable that carries multiple TV channels to your television set.
We will define broadband as internet access through non-traditional media (other than dial-up over telephone lines)with downstream speeds of at least 64 KBPS . We say a lower limit of 64 KBPS because a dial-up modem on a telephone line can deliver up to 56 KBPS downstream.). When we talk of non-traditional media ,we ‘re actually talking of only two options currently-Internet over cable and digital subscriber line(DSL).when we talk of DSL,we’re actually talking of a number of technologies like ADSL, SDSL, HDSL, IDSL, and VDSL, all of which deliver internet connects at varying speeds over existing telephone connections without using the all-too-familiar dial –up modem the most common DSL implementation in India today is ADSL or asynchronous DSL.
ADSL can deliver from 1.5-9 Mbps down stream (to the user) and 16-640 kbps upstream (user requests to web servers).
Ideally, when we talk of broad band,we refer to connections to the home ,and not to the workplace.Why is that ? typically home user will have more data sent down to him in the form of downloaded software or stream music or vedio,than data sent back to the net.On the other hand,bussiness will need to send more data out into the net,in the form of data served from web servers they host or software and data transferred to business partners . Asymmetric technologies like ADSL and internet over cable can’t support this need to transfer data out on to the net.So,corporates would ideally opt for symmetric options-leased lines or the like-here data transfer rate are high in both directions.
However not all businesses need to transfer huge amounts of data out with most Indian web site being hosted at separated data center the roll of the corporate Internet connections becomes limited to sending and receiving e-mail and browsing the web in such a situation broadband can use d as a corporate solution also .
Another advantage of broadband is that it does not tie up your telephone line and,consequently doesn’t saddle you with heavy telephone bills.On the flip side ,while usage charges for broadband tend to be low ,the cost of equipment ,like a DSL or cable modem,can be pretty high. Citing these savings in telephone charges ,some ISPs offer 32 kbps connects as an option. Does this qualify as broadband ?the band width is not at all broad in this case and you may actually take more time to down load software or brows the web than you would on a good dial-up connections but then you do save a packet on telephone charges.
How do you choose between service providers? You may not have much of choice here.it’s your cable TV provider who will double up as your internet over cable provider in the of DSL,too,the market has not big enough for competition yet most service providers currently operate in mutually exclusively territories.
What about the choice between cable and DSL? Here again ,the story is more or less the same .if you’re lucky enough to have a choice between cable and DSL,and with other things like back bone and gateway bandwidths of service provider being equal,DSL may work out to be better and with cable in the long run. This is because cable is a shared media. This is ,the cable that comes to your house runs to your neighbor’s. As more and more users are added to the segment of cable that you’re on , the available bandwidth will get shared between all of them.
