Growing, with Bluetooth technology started as a basic wireless connection standard but since then have been adjusted and has been proven with various different uses and functions.

A good example is Bluetooth for mobile phones. This allows users to connect to their hands-free without using the headset cable. Bluetooth technology
will also allow mobile phone users to connect with their hands free kit also.

Other useful is using the Bluetooth file sharing. This allows the sharing of files between two mobile phones, between phone and computer, which makes
a snap to share files. If you have a mobile phone and the computer, you can transfer data between both.

Devices connected, however, must agree on frequency they will use next. Specifications Bluetooth ensures this in two ways. First, defines the type of master and slave relationship between Bluetooth devices. Next, he set an algorithm devices that use the specific information when calculate the frequency hop sequence.

A Bluetooth device that operates in master mode can be communicate with up to seven devices that are set in Slave mode. For each slave, master
Bluetooth device will send its own unique address and the value of its own internal clock. The sent this information then used to calculate
frequency hop sequences.

Because the master  device and each slave using the same device with the same initial algorithm input, the device is connected will always arrive
together in the next frequency that they have agreed against.

Technology as a replacement for cable, no wonder that Bluetooth devices are battery powered, such as a wireless mouse and a battery powered
mobile phone. To conserve power, most devices operate at low power. This will help provide Bluetooth range of the device for about 5 – 10 meters.

This is far enough to reach the wireless communication but close enough to avoid drawing too much power resources of the device.
