How Bluetooth Headphones Work

By Gary Scott

What exactly is blue tooth technology and how does it work exactly? We are here to answer these questions so that you can better understand the opportunities that come with this type of technology. There are many myths out there about how blue tooth works and we have written this article to put these myths to bed.

Blue tooth was created by several companies that cooperated together to set up a short frequency wireless technology for transferring data amongst devices. Some of the companies that participated in creating blue tooth technology were intel, toshiba, nokia, ibm, and samsung just to name a few. Blue tooth frequencies is a certain protocol that can be used by several types of devices.

This computer language allows blue tooth devices to communicate with each other in a master/slave environment format. This means that only one device is the master or brain, while the other devices follows its every command. The coolest part about all of this is that the master blue tooth device can connect to several different slaves meaning that many blue tooth devices can be paired to one master such as a cell phone or computer.

Myths range from blue tooth being a broadband networking feature and signal. This is simply not true. Blue tooth cell phones and bluetooth headsets use a personal area networking technology that can be used in many different types of applications. Blue tooth devices use the same frequency range, which is about 2.4 GHZ, as the Wi-Fi technology 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.

Another special feature is that devices that use this technology only use needed power to turn on when the brain (master) tells it to turn on. A good example of this is the common cell phone blue tooth 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.

Utilize this very special technology and start using devices that that can help you in your day to day activities.
