Handheld devices like a cell phone, palmtop and laptop were rapidly becoming an integral part of our daily lives. In most cases, these devices do not have compatible data communication interfaces, or, if they do, the interface requires cumbersome cable connections and configuration procedures. Isn’t it absolutely fantastic to connect your PC to share music, data and calendar info without using any wires? Or to wirelessly access phone numbers on your PDA from your cell phone. Driving without holding the handset makes it dramatically safer and easier. Accessing the internet, print files from your computer and print photos taken from a digital camera without a single piece of wire lying in your office.
An obvious solution was to get rid of the cables and use short-range, wireless, inexpensive and universally adopted by device vendors to facilitate on-demand connectivity among devices .The marvel of engineering gave us the freedom of exchanging data without using yards of wires and popularly known as Bluetooth.
