How Bluetooth Works

August 8th, 2008 by power

Bluetooth technology for cellular phones is a form of short-range wireless communication device that allows two electronic devices to work without cables and wires. This means that you are able to have a cell phone conversation by way of a headset, or you can use a mouse for your smart phone, without having to hook these additional devices up with wires. All of the devices work through the same core system – the Bluetooth technology.

Bluetooth works using a physical layer referred to as the Bluetooth RF transceiver. This operates within the unlicensed ISM band which is centered at 2.4 gigahertz. Two point four gigahertz is the same range of frequencies which are utilized by Wi-Fi and microwaves). The very foundation of the system utilizes a transceiver which is capable of hopping frequencies in order to prevent fading and interference.

RF topology – also known as start topology – is used within all Bluetooth devices. When a group of such devices are synchronized together, the grouping is referred to as a piconet, which includes a master device and up to seven active slave devices. Further slaves may also be included, though they cannot also be actively participating in that network. However, one device may be applied in more than one piconet and can be either a master or a slave. Read the rest of this entry »

Bluetooth technology has evolved tremendously since the year 1999 and helped make wireless communication the wave of the future by allowing two devices to “talk” to one another over low-frequency radio waves. Bluetooth headsets have gained immense popularity and also have evolved as the best hands free option after mobile phone driving bans getting stricter. With California’s new hands-free law going into effect bluetooth headsets have certainly become indispensable.

Bluetooth headsets have become the preferred method of going hands-free for most consumers’ infact. They’re more versatile than external speakerphones because you can use them outside as well as inside a car. Unlike a wired headset, you don’t have to worry about the wires connecting the headset and phone getting tangled or caught on things. Also just as the number of headsets has exploded, the number of Bluetooth mobile phones has increased as well.

Varieties of bluetooth headsets are easily available now days in the market. Bluetooth headsets can range in cost from about $10 for a low-end model to $150 or more for a top-of-the-line model. Naturally more expensive headsets tend to be smaller, more stylish and offer more and better features than less expensive models. But if you are looking for a decent headset then you can get a light-weight headset with noise cancellation technology - perhaps the most important feature for in-car use - in the $45 to $85 price range.
