The characteristics of Bluetooth

         Bluetooth can achieve data transmission speed of 1Mb / s. Bluetooth supports data transfer speeds up to 720 Kbps in the range of 10 meters. Unlike infrared connection (IrDA), Bluetooth is a scalar and using 2.4 GHz spectrum.

-       power consumption low, allowing applications in a variety of devices, including handheld devices and mobile phones.

-     Low price (the price of a Bluetooth chip is decreasing).

-     distance communication allows:

+ The distance between two terminals can be up to 10 meters and 5 meters outside the building.

+ Gap terminal and the access point can be up to 100m outdoors and 30m indoors.

-     Bluetooth uses the 2.4GHz spectrum range registration ISM band. Speed data transmission can reach a maximum 1Mbps (by using high frequency) that the devices do not need to take each other directly.

-     Easy application development: an application Bluetooth connection with another application via the standard Bluetooth profiles ", which may be independent of hardware and operating system used.

-    Bluetooth is used in data communications and said there are 3 channels to transmit voice as 7 channels for transmitting data in a private network.

-    Safety and security: integrated with authentication and encryption.

-    High compatibility, many hardware manufacturers and software support.
