1. A method, comprising:

  • receiving, by an apparatus from a remote device, one or more wireless packets including information packets containing angle of departure information of the remote device;

    sampling and decoding, by the apparatus, a reference data stream of direction estimation data in the received angle of departure information, the sampling and decoding performed for first and second locations separated by a separation distance;

    determining in the apparatus, a first angle of departure and a second angle of departure from the received angle of departure information, based on the sampling and decoding performed for the first and second locations; and

    generating distance estimation data in the apparatus relative to the remote device, based on a difference between the first angle of departure and second angle of departure, and on the separation distance.
