Understanding Bluetooth Wireless Communication
If
You Don’t Know What Bluetooth Is...
There was a time when the world was vast,
mystic, and beyond one’s imagination. The communication was
a dreaded task, because the messages used to take a very long
span of time to reach from one point to the next. But as soon
as the technologies started peeping through the horizon, it
utterly modified everything within its grasp. Since then every
throbbing moment has been a new moment with the newer and newer
technology. Computer technology came to the scene with the
global revolutionary effect. But again, this is going to be
a topic of history today. The Bluetooth technology is the latest
and the most powerful technology that has made the globe completely
wireless. Now the question arises: what the Bluetooth technology
actually means?
Bluetooth
technology is a radio-based wireless communication technology,
where the cable connections of the modern hi-tech devices
have been completely cut off – thereby
maintaining a high degree of efficiency with utmost security.
Each Bluetooth enabled electronic device is cent percent capable
to successfully communicate, at a time, with as many as seven
other Bluetooth enabled devices within a short range of distance
– ranging from 1 meter to 10 meters depending on the radio
class. In such case all the devices to be connected must lie
within a single network system. This needs no cables, no wires
– nothing and hence the users find an end to the headache due
to false connections and/or loose connections. This is the
end of snaking around of wires behind the desktop also.
There are in fact three class categories of range – Class
1, Class 2 and Class 3, which the operation of the device depends
on. The highest range of operation falls under Class 1 Radios,
which is of 100 meters or 300 meters range. This category is
specifically used in case of the industries and generally not
for domestic purpose. The second highest range of operation
falls under Class 2 Radios, with an operation range of 10 meters
or 30 meters. This category has found its scope in case of
the mobile devices. Lastly, the Class 3 Radios is used to operate
the devices within a very short range of 1meter or 3 feet.
The most lucrative and interesting fact about this technology
is that, it transmits not only the data but is equally
efficient in managing the voice transmissions as well. By this one can
really enjoy a sequence of remarkable facilities of hands-free
systems for almost all the electronic devices – starting from
a mere mobile phone to the hi-tech Personal Digital Assistants
with an exceptionally low power consumption property. This
wireless communication technology enables a wide range of electronic
devices, like a digital camera, a PDA, a mobile phone and a
laptop, to get wirelessly interconnected and coordinated to
perform a wide varieties of tasks simultaneously with astonishingly
high degree efficiency. The Bluetooth technology has cast a
serious favorable impact on the modern industrial, medical,
and other scientific aspects – accelerating the scientific
advancement to a far higher pace.
Bluetooth connects a device to the other through the latest
network system – commonly called “Piconets”. This technology
smartly operates at 2.40 GHz to 2.485 GHz ISM band, while only
the former (i.e. 2.40 GHz) is unlicensed and easily available
in most parts of the world. ISM, here, refers to Industrial,
Scientific and Medical band. While operating, Bluetooth technology
uses spread spectrum, frequency hopping and full-duplex signal
at a rate -- as lower as – 1600 hops per second. AFH -- Adaptive
Frequency Hopping is another supportive technology, which makes
the Bluetooth interference tolerant. This enables Bluetooth
to send and receive an interference free transmission. The
latest version of Bluetooth technology is 2.0+ Enhanced Data
Rate, which supports a data rate of 3 Mbps. This version was
adopted in the year 2004, November. Prior to this, 1.2 version
was adopted in 2003, November, which supports at most 1 Mbps
data rate.
The world is on move with Bluetooth and this technology has
earned the worldwide acceptance for it high degree of reliability
and efficiency. Science is taking a new turn and is going to
get a new shape. Bluetooth will likely become a household name
to everyone in the world as well.
