What is Bluetooth and How Does it Work?
This is the bluetooth logo which helps buyers make sure they are getting the true technology in a hands free device. Make sure that any bluetooth device you buy has the logo on it which will ensure that this technology is the backbone of the device’s operation.
What exactly is bluetooth technology and how does it work? We are here to answer these questions so that you can understand the possibilities that come with this technology. There are many myths out there about how bluetooth works and we have written this article to put these myths to bed.
Bluetooth was created by many companies that came together to set up a short frequency wireless technology for transferring data. Some of the companies that participated in creating bluetooth were intel, toshiba, nokia, ibm, compaq, dell, and samsung just to name a few. Bluetooth is a certain protocol that can be used by communication devices. This protocol is it’s own language just like java or c++. This special language allows devices to communicate with each other in a master/slave operational format. This means that one device is the master or brain, and the other device follows it’s commands. The neat part about this is that the master can connect to several different slaves meaning that many bluetooth devices can be paired to one master such as a cell phone or computer.
The creators of bluetooth technology have made it very easy for users to pair these slaves and masters together using a discovery mode. This allows the devices to find each other automatically and then asks the user to pair them together. Devices typically have a pin number so that devices don’t accidentally pair to one each other when the user does not want them to.
Common myths range from bluetooth being a broadband networking feature. This is not true. Bluetooth headsets and bluetooth headphones use a personal area networking technology that can be used in many applications. Bluetooth devices use the same frequency range, which is about 2.4 GHZ, as the Wi-Fi system. The enhanced versions of bluetooth devices utilize Ultra-Wide Band frequencies that contribute to increased date rate and improves the signal strength allowing users to be further away from working devices without losing a signal.
The other really neat feature is that devices only use needed power to operate when the brain (master) tells it to turn on. An example of this is the common cell phone bluetooth headset. This headset stays in standby mode until the phone rings and turns it on. This saves battery life and extends device life so that you can keep a device on all day without worry that the battery will run out.
We hope this has given you a basic understanding behind the marvelous technology of bluetooth.
