With Bluetooth 5.1, a new standard was released in 2019, which will make it possible to carry out a so-called direction finding. Two antennas will be controlled phase-shifted, so that a mini-phased array can be realized. This will improve the proximity estimation. However, these chips are not yet implemented in the current smart phones and are therefore not available.

    With Bluetooth 5.1, a new standard was released in 2019, which will make it possible to carry out a so-called direction finding. Two antennas will be controlled phase-shifted, so that a mini-phased array can be realized. This will improve the proximity estimation. However, these chips are not yet implemented in the current smart phones and are therefore not available.
