Bluetooth is a wireless communication technology designed to transmit multimedia content (voice, data, and images) with high bitrates in PANs (Personal Area Networks).
Bluetooth standard has been promoted by the Bluetooth SIG, a private non-profit association founded in 1998 by Ericsson, IBM, Intel, Toshiba and Nokia, with more than 14,000 companies nowadays. The group is focused on publishing Bluetooth specifications, managing the compatibility program and promoting technology.
The most typical Bluetooth application is the hands-free mobile phone kit in a car. However there are many other applications where Bluetooth replaces the wires, e.g. remote controls on consoles, earphones and other medical devices, for data transmission at sensors in industrial automation, etc…
The Bluetooth standard is based on IEEE 802.15.1 protocol working at 2,4 GHz free ISM band. The most recent version 4.0 is called Bluetooth Smart o Bluetooth Low Energy (BLE), and has been designed to reduce the energy consumption by efficiently managing the connections, pairing and re-pairing of connected gadgets. It focuses on sending smaller bits of data when needed and then puts the connection to sleep during periods of non-use.
BLE is the basis for the iBeacon (Apple trade mark), enabling a smart phone or other device to perform actions when in close proximity to it.
TST has developed its own beacon enabled to work with TSmarT family.
