Bluetooth technology provides two modes of communication: Basic Rate/Enhanced Data Rate (BR/EDR), which is suitable for continuous wireless connections for one-to-one device communications, and Low Energy (LE), which allows for short bursts of data transfer and thus expands the use of Bluetooth radio to low-power applications. In addition to point-to-point (P2P) networking, the LE mode supports one-to-many broadcasting and many-to-many mesh networking with high reliability and scalability.
Toshiba is leading the way in the use of low-power technology for Bluetooth applications. Bluetooth communication is becoming widely used in power-sensitive coin-cell-operated applications into which a Bluetooth function could not previously be incorporated. This trend is enabling the wireless collection and statistical analysis of data, contributing to creation of new value. The Bluetooth one-to-many data broadcast mode is finding more applications such as accurate positioning using Bluetooth beacons and sharing of sensor data.
In the coming years, many-to-many wireless communication using a mesh topology will be realized. Easy Setup and Easy Maintenance will become the key factors of the mesh's success. Once they are realized, the reliability and scalability will also be realized in the systems while data security being maintained.
