Bluetooth technology essentially works by using short-range wireless communication technology to connect two devices together.
This eliminates the need for cables or wires. Bluetooth allows you to listen to music your from your mobile phone, tablet or iPad through wireless headphones.
The following is a short description of how Bluetooth works.
Bluetooth technology uses short-range radio to link two device together. This eliminates the use of cables to connect various portable electronic devices such as headphones.
The standards of Bluetooth specify a uniform structure for communication between a wide range of devices with minimal user effort.
So, another way to look at Bluetooth is that it is a robust, simple and economical technology that offers wireless access to Local Area Networks, mobile phone networks, the Internet and so much more.
How does Bluetooth work?
Bluetooth technology requires that a low-cost transceiver chip be included in each device. The transceiver transmits and receives in a previously unused frequency band of 2.45 GHz that is available globally — with some variation of bandwidth in different countries.
In addition to data, up to three voice channels are available. Each device has a unique 48-bit address from the IEEE 802 standard. Bluetooth connections can be point to point or multipoint.
The maximum Bluetooth range is 10 meters. Data can be exchanged at a rate of 1 megabit per second — up to 2 Mbps in the second generation of the technology.
A frequency hop scheme allows devices to communicate even in areas with a great deal of electromagnetic interference. Built-in encryption and verification is provided.
