Bluetooth is also widely used these days to wirelessly access data transfer and communication services. Wired networks used continuously running data cables to provide communication and data transfer services. Communication and data transfer is possible through the use of electrical signals. On the other hand, wireless setups utilize radio waves. It may be difficult (though not impossible) to access the flow of data in a wired network, in a wireless network, it has become possible. All one needs is the right equipment and the know-how to do it. This has emerged as the most major drawback of wireless services.
