Right now if you are working on the computer, just see the clutter on your table
with all sorts of cables going here and there. There is this cable connecting
the keyboard to your base unit, the mouse, the monitor, the printer, etc all
are connected with cables. At times when something goes wrong like a connection becomes loose
or there is a sudden computer shut down, you try to find out by checking all the devices
connected to each other. This can take some time since you are wondering which
cable is going where and you soon get rather confused!
Bluetooth wireless technology may solve your problems. Bluetooth is the
technology where different instruments manufactured by different companies
can communicate with each other with ease. Bluetooth is named after a renowned
king sharing the same name who was fond of easy communication among his people.
This is a wireless technology with a negligibly low power radio signal and
allows wireless access to certain devices within about 30-35 feet. The difference
between Bluetooth standards and other wireless standards is that the former
specifications include both link layer and application layer definitions for
product developers.
This technology was invented on the principles of low power, low cost, security
and easy to use. This is good for those who regularly use hand held communication
devices. Very soon this will replace the wired technology involved in various
computing systems. Different devices like desktop and notebook computers, hand-helds,
personal digital assistants, mobile phones, camera phones, printers, digital
cameras, headsets, keyboards and even a computer mouse can be connected to
each other with the aid of Bluetooth. Earlier transfer of data from one device
to the other was really a struggle amd sometimes very time consuming. End users may now
enjoy far less chaotic data transfer.
At present Bluetooth offers to connect up to 7 devices. Though it
communicates with one device at a time, it can switch between the other
6 too. The devices
connected are electronic but this technology does not interrupt in the functionality
of any one of them since this technology works on a very low frequency. The
network using this type of technology is known as the Bluetoth Personal Area
Network.
Bluetooth is different from other technologies since it is a wireless technology.
If 2 devices have this installed they can communicate without any wirings connecting
them. One can easily receive or emails on his mobile phone without wired connectivity.
Advantages of Bluetooth Technology
1. Cost Effectiveness: This is cost effective since the cost of connectivity
and their recurring costs are not involved.
2. Tidier: Since it is wireless your work-station is tidier without
the clutter of various wires going here and there and also less hazardous.
Just imagine, you are working on your computer and suddenly you remember your
girlfriend's birthday and you want to make a call. You do it from your computer
itself instead of the mobile since both have Bluetooth installed, without even
a clue to others around you.
3. It is very standardized which guarantees a high level of inter operateability.
4. It operates on bi-directional mode
5. Voice and data coexists in this technology.
6. Interaction of locally connected so many peripherals are there which is
called peer to peer or ad-hoc network.
7. There is an acknowledgement system guaranteed for data transmission.
8. It has a very strong frequency hopping technology and has a reliable error
correcting codes compared to 433MHz, or even WiFi type systems
9. Energy consumed in this technology is very low.
Limitations of Bluetooth
1. Short Range operations: This technology is useful in only short range of
operations. That means the devices exchanging information have to be carried
along if moving with a laptop to somewhere outside the range. Hence it can
be said that this system is unable to cope with mobility.
2. Bluetooth standards does not address routing in piconets and scatternets.
3. Multi-hop multicasting is absent in this technology.
4. Bluetooth is not fully developed and integrated into all the products involved
WE have to still wait for it to get fully evolved.
Since bluetooth supports PAN, in the long run, this technology will survive
if more and more consumers are interested in PAN. This technology will be
implemented in most big markets since it has a good inter operateability
between various devices. Since it depends upon mass development and mass
implementation, either this will be a big success in the market or a big
flop.
