Problem: Today, electronics that connect to one another are found everywhere--in the office, home, Car, etc. Keyboards connect to computers, MP3 players to headphones and so on. So, how do these devices connect to each other? Usually the answer is: with wires and cables. But, as you know, wires and cables always result in a tangled mess.

What is Bluetooth technology? Put simply, Bluetooth technology is a short-range wireless radio technology

that allows electronic devices to connect to one another. Generally, Bluetooth has a range of up to 30

ft. or greater, depending on the Bluetooth Core Specification Version. Newer devices, using newer versions of Bluetooth, have ranges over 100 ft. It is

intended to be used for both voice and data communications. Bluetooth is a very common

standard for wireless communications between cell phones and PDAs, headsets.
