Craze of Bluetooth

Hello friends this is my first blog and in this blog I m going to tell you about “Bluetooth” technology and how it works, what are their advantages and disadvantages and a lot of stuff about Bluetooth Technology. First of all, I want to told you from where word “Bluetooth” came, it put on the name of a great Denmark king whose name was “Harald Bluetooth” a thousand years of ago. Now the question is, what is bluetooth technology, actually it is a technology which is used for low-power radio communications to wirelessly link phones, computers and other network devices over short distances. Initially it was developed for support of personal wireless devices including cell phones, PDAs, and wireless headsets.The signals that are transmitted through “Bluetooth” devices are short distance in nature, they diminishes after 10m(30 feet).The data transferred through Bluetooth devices is at a rate of less than 1Mbps.As I already told you “Bluetooth” devices works on the principle of radio communication systems, so it is not required that the two Bluetooth devices must be in line of sight of each other, they can be either in different rooms, as long as the received transmission is powerful enough. Today,there are many bluetooth enabled devices exists such as phones, printers, modems and headsets etc. This technology is useful only when the Bluetooth enabled devices are present in low- bandwidth position. Today Bluetooth is mainly used in cell phones to transfer sound data, or text data with laptops, and from Bluetooth enabled devices.

From the security point of view, the data transferred between blue tooth devices is encrypted through some custom algorithms so that it can be safely transmitted. Hence, we can say that data transferred through Bluetooth devices is secure.As, the work is going on the development of Bluetooth so that it can be made more faster,simpler in comparison to other wireless technology.
