With Bluetooth technology, this spectrum is unlicensed, even (radio frequency) techniques. small transceiver modules can be more uses for it are expected to be built into a wide range of products, devised in the future. As the band allowing fast and secure transmission becomes more widely used, radio of data and/or voice within a given interference will increase. To counter radius (usually 10 meters).
