Statements
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.
