International Operation
You can use Bluetooth almost anywhere. The radio operates in the 2.45 GHz band, which is
Easy Connection
You can establish a connection between two or more devices almost instantly. The connection will be maintained even if the devices are not within line of sight.
Stable Connection
Bluetooth provides a very stable connection. The technology ensures that, under normal circumstances, you will not be bothered by interference from other radio signals operating in the same frequency band.
Audio and Data
You can use a Bluetooth enabled device for data transfer or audio communication; or you can use it for both simultaneously.
Range
Bluetooth is based on
Bandwidth
A Bluetooth radio link has a maximum data transfer rate of 724 kbit/s, or three voice channels; the data rate for a voice channel is 64 kbit/s.
Security
Two advanced security mechanisms ensure a high level of security: Authentication prevents access to critical data and makes it impossible to falsify the origin of a message.
Encryption prevents eavesdropping and maintains link privacy.
Low Power Usage
The Bluetooth radio is very economical, limiting its output power exactly to what is actually needed. For instance, when transmitting to a receiving radio that is only a couple of meters away, the radio immediately modifies its signal strength to suit the small distance. Bluetooth consumes only a tiny bit of the power that eg. a mobile phone needs.
