How it works Edit
Bluetooth piconets are often established on a temporary and changing basis, which offers communication flexibility and scalability between mobile devices. Some key benefits of Bluetooth technology are:
- Cable replacement. Bluetooth technology replaces a variety of cables, such as those traditionally used for peripheral devices (e.g., mouse and keyboard connections), printers, and wireless headsets and ear buds that interface with personal computers (PC) or mobile telephones.
- Ease of file sharing. A Bluetooth-enabled device can form a piconet to support file-sharing capabilities with other Bluetooth devices, such as laptops.
- Wireless synchronization. Bluetooth provides automatic synchronization between Bluetooth-enabled devices. For example, Bluetooth allows synchronization of contact information contained in electronic address books and calendars.
- Internet connectivity. A Bluetooth device with Internet connectivity can share that access with other Bluetooth devices. For example, a laptop can use a Bluetooth connection to have a mobile phone establish a dial-up connection, so that the laptop can access the Internet through the phone.
Although only one device can serve as the master for each piconet, time division multiplexing (TDM) allows a slave in one piconet to act as the master for another piconet simultaneously, thus creating a chain of networks called a scatternet.
