The new Bluetooth standard will increase data transfer speeds by almost 4 times. Modern devices with Bluetooth LE support provide a maximum data transfer rate at the physical level of up to 2 Mbit/s. As connected devices become more complex, this limitation becomes an increasingly significant obstacle. The Bluetooth SIG revealed a significant improvement to the Bluetooth LE architecture. The new HDT standard is designed for data transfer rates of up to 7.5 megabits per second. That is, Bluetooth will immediately speed up almost four times compared to the current LE 2M PHY specification.
