Technology Behind Bluetooth
Bluetooth Connections
Bluetooth is essentially a networking standard that requires two levels of connections to work. The physical level connection is created through a radio frequency standardized at about 2.4 GHz. A second connection is established at the protocol level. Howstuffworks.com describes the,protocol level as a system that allows different products, such as a cell phone and an earpiece, agree on when bits are sent, how many will be sent at a time, and how the parties in the conversation will be sure that the messages received are the same as the messages sent.
The connections established by Bluetooth operate smoother than a similar infrared signal, because the standard does not require a line of sight to connect. Another advantage of Bluetooth technology over infrared is that multiple connections can be made, utilized, and sustained simultaneously, as opposed to infrared's one-on-one technology.
Joining Bluetooth Devices
Bluetooth networks use the same unlicensed radio frequency used by WiFi networks, cordless phones and microwave ovens. While the Bluetooth technology specification is defined and bound by low-level radio communication protocols, the standard provides a high level of content exchange through its unique communication protocols. These protocols are known as profiles or networks and are created when a Bluetooth device detects other Bluetooth devices within its range, with appropriate authorization and permission, and forms connections with them.
Additionally, Bluetooth networks can be merged or joined together to form large networks capable of covering large spaces, like grand halls and convention centers. A new Bluetooth device joining a network gets the added benefit of seeing all other devices in that network, which allows some devices to act, in effect, as bridges to the network as a whole. Bluetooth devices in the same network or in the same profile are able to exchange content with each other independently or through a bridge device seamlessly at the network level. A cell phone and its wireless audio earpiece support the headset profile. PDAs, smart phones and personal computers support the same synchronization profile for address book/calendar/to-do list/ email synchronization.
