| are many myths out there about how Bluetooth | | | | frequencies that contribute to increased date rate |
| works and we have written this article to put | | | | and improves the signal strength allowing users to |

| Bluetooth is a certain protocol that can be used | | | | Devices typically have a pin number so that |

| language allows devices to communicate with | | | | The other really neat feature is that devices only |
| each other in a master/slave operational format. | | | | use needed power to operate when the brain |
| This means that one device is the master or | | | | (master) tells it to turn on. An example of this is |

| The neat part about this is that the master can | | | | headset stays in standby mode until the phone |
| connect to several different slaves meaning that | | | | rings and turns it on. This saves battery life and |
| many Bluetooth devices can be paired to one | | | | extends device life so that you can keep a device |
