How Does Bluetooth Work?


Have you ever got tangled in wires while setting a computer or speakers? Then you must know how hard it is to deal with wires. But thanks to the latest technology, we are quite a bit free from wires. Bluetooth is a simpler way for mobiles, printers, Computers, digital cameras, and other gadgets to link together over rather short distances using radio waves technology. You have seen people using wireless mouse and keyboard with their desktop or answering a call via a small headset. This all is possible because of Bluetooth technology.

Bluetooth is based on radio-wave technology which is mainly designed for communicating over short distances less than or about 10m or 30ft. Bluetooth receives and sends radio waves in a band of 79 various frequencies or channels which is centered on 2.45 GHz. If you worry that you are going to interfere with other people’s life support machines then there is good news for you. Bluetooth is a short-range transmitter, so your home devices won’t carry your signals that much far. Short-range Bluetooth devices are more secure than long-range Bluetooth devices.

Another plus point is that Bluetooth devices usually automatically spot and connect to each other and up to eight of them can communicate at any one time. And again they don’t overlap or interfere with one another as they all use a different channel from 79 available channels. This is why when two Bluetooth enabled devices, for example, mobile phones or headphones came into the close distance to each other, they pair or connect. A single Bluetooth headset can even pair to multiple devices at the same time.
This ensures you to talk on the cell phones or listen to music without getting tangled into wires or cords.
