is a hard challenge since consideration has to be taken in the entire protocol stack
layers. The design of Bluetooth devices should be constructed in such way that it
won’t be a burden on the battery lifetime. To avoid high power consumption in
Bluetooth radio different levels of power conserving mode are included in the
constructions and some of them are sniff, hold and park. Some other aspects that
need to be considered too are base band mode and adaptive transmission power.
The absorbing range for Bluetooth devices is around 1-35 Am.
Advantage and disadvantage
The main disadvantage with Bluetooth is the limitation of how far it can reach
considering the range between devices communicating with each other. Another
aspect that is also disadvantage for Bluetooth technology is the number of devices
that can be connected simultaneously is only 7 devices. Now the positive side of
Bluetooth is the power consumption since it consume very little power while active
it give a beneficial of long time battery life compare to Wi-Fi which only last for
couple of hours.
Comparison between Wi-Fi and Bluetooth
Both have lots of features of connectivity, printing and transferring of data. The
technology of Bluetooth is functional when broadcasting of information among
more than two devices exist near as headset, modem, printer etc. while Wi-Fi
operating on full scale because it is a much faster than Bluetooth. No doubt Wi-Fi
and Bluetooth is the basic need of modern age but have some differentiation as
follow.
The hardware requirements of Wi-Fi and Bluetooth are entirely different, Through
Bluetooth adapter you can connect devices with each other. While in Wi-Fi network
you need an adapter, router and access point to enable connection. The bandwidth
required for Bluetooth is only 800 kbps and for Wi-Fi 11Mbps bandwidth require.
Wi-Fi network come into existence in 1991 and Bluetooth in 1994.The specification
of Bluetooth is SIG and Wi-Fi is IEEE, and WECA.
