Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength radio transmissions in the ISM band from 2400–2480 MHz) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. Created by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization. Bluetooth technology is a wireless method of transferring data between two or more electronic devices. Compatible Bluetooth devices in range of each other automatically connect to one another. You may have seen people walking around wearing Bluetooth earpieces or headsets to speak hands-free via a wirelessly connected phone. While this is a useful feature made possible with Bluetooth, there are several other applications of the technology.
TYPES OF BLUETOOH
Bluetooth technology is also available in portable devices. Many smart phones make use of Bluetooth for wireless Internet and for pairing with other nearby devices. Some GPS devices use Bluetooth to not only helps you with directions, but also to get traffic updates and locate nearby vendors such as restaurants or gas stations. Some cameras and camcorders use Bluetooth wireless to make it simpler for you to transfer pictures and videos from the device to your computer.
Those headsets you've seen are one of the more prominent uses of Bluetooth technology. They pair with your Bluetooth-enabled Smartphone to allow you to have hands-free conversations, which come in handy when you're looking over reports or driving around. You can also get Bluetooth mini-keyboards to make it easier to type text messages and emails on your phone, and Bluetooth speakers for your phone. Finally, you can connect a call to your car stereo to hear the other person through your speakers. Computers and Office Equipment
More and more offices are making use of Bluetooth to connect their workstations to shared equipment such as printers, scanners and even keyboards. Not only does this make it easier to connect your equipment, but it also eliminates the need for countless yards of cords running around the office. However, Bluetooth has a limited range – generally about 33 feet – so if you have a larger office, you will need to carefully consider where you place equipment in relation to your workstations. Dongles
Dongles are small devices that you plug into a computer that is not Bluetooth enabled to give it Bluetooth wireless capabilities. Dongles resemble USB flash drives and fit into USB ports on the computer. This lets you connect other Bluetooth devices to your computer, such as a mouse, keyboard, camera or a headset. Like any other Bluetooth equipment, these external devices must be within range of the broadcasting dongle to establish a connection.
USES OF BLUETOOTH
Bluetooth has been an impressive wireless technology to enable all sorts of cool functionality with multiple gadgets. While it was rather limited during the early stages of its life, Bluetooth has evolved to be capable of plenty of different data communications. Especially now that the latest revisions of the Bluetooth specifications include some great energy efficiency, now is better than ever to connect devices to your Android phone via Bluetooth. Here are some of the top uses for this great technology.
Without Bluetooth, it’d be a lot harder to imagine a world of hands-free talking. Bluetooth headsets and Bluetooth-enabled car stereos allow you to keep your phone in your pocket while you talk. Although the idea of having a system with a microphone and speaker – such as a headset or car stereo – is rather simple, the wireless nature makes it seamless and ideal. MUSIC
But why stop at just headsets and other hands-free calling features? There are also Bluetooth headphones available which allow...
