The future of technology - Everything will be digital
the digital world there are no movies or music or magazines but
just 1s & 0s termed as bits. The ability to move these bits
is called BANDWIDTH. Broadband is the ability to move lots of bits
per second. A computer doesn't necessarily consume bits in a continuous
fashion like water. In the future the broadband will be more ASYNCHRONOUS.
For example, interleaving people's conversation, packetizing them,
so that many people share the same channel without being aware that
they are. In the larger sense we can at our convenience receive
& send data. Like watching your favorite Bay-Watch TV programme
at a time you want to watch and not at 10 pm on Star World.
Plugs are in the past and the future consumption of bits will be
very conversational & bursty. The batteries will be less power
hungry and there will be improved use of radio frequencies (RF).
Ultimately all long distance traffic will be fiber optic and all
short distance traffic will be RF. Everything electronic will talk
to other electronic appliances using RF and computers will come
out of the box and our grandchildren will look back at our PC's
as quaint artifacts, as common tomorrow as an
ice tray today.
Bluetooth is a global de facto standard for wireless connectivity.
Based on a
low-cost, short-range radio link, it cuts the cords that used to
tie up digital devices. BlueTooth technology was conceived in 1998
when the leaders in mobile telephones, laptop computing & signal
processing technologies viz., Ericsson, Nokia, IBM, Toshiba and
Intel grouped to form Special Interest Group (SIG).
When two Bluetooth equipped devices come within ten metres range
of each other, they can establish a connection together. And because
Bluetooth utilizes a radio-based link, it doesn't require a line-of-sight
connection in order to communicate. Your laptop could send information
to a printer in the next room, or your microwave could send a message
to your mobile phone telling you that your meal is ready.
In the future, Bluetooth is likely to be standard in tens of millions
of mobile phones, PCs, laptops and a whole range of other electronic
devices. As a result, the market is going to demand new innovative
applications, value-added services, end-to-end solutions and much
more. The possibilities opened up really are limitless, and because
the radio frequency used is globally available.
Imagine some of these everyday examples: you enter a train and
your fare is automatically paid by your mobile phone. Or you get
an automatic text message notifying that your kids are safely back
from school. Or while waiting at the airport lounge, you get some
interesting duty-free offers directly to your mobile phone. You
could play multiplayer games with your friends, or write e-mails
on your laptop on the 'plane, then when you land and switch on your
handset, the messages can be automatically sent by your phone. Bluetooth
will also allow you to surf the Web with your laptop while your
phone is in your bag. Together with other industry initiatives,
such as WAP (Wireless Application Protocol) and Symbian, Bluetooth
will have tremendous effects on everyday life in the near future.
