What Is Bluetooth?
January 31st, 2010It’s built into everything from cell phone earpieces to car stereos, but what exactly is Bluetooth? Well, Bluetooth is a short-range wireless protocol that faciliates data transfer and communication between both portable and fixed-position devices. In simpler terms, Bluetooth is wireless replacement for cables: it lets your devices and appliances talk to each other without a physical connection. Using a technology called frequency-hopping spread spectrum, the Bluetooth system breaks up data into frames before broadcasting it in an licence-free frequency band (2.4Ghz to 2.48Ghz ISM), allowing it to rapidly transfer data without using up lots of power.
