1. An apparatus comprising:
an array of antennas to sequentially transmit, in a first mode, first probe request messages in a number of beam steering directions to a device, wherein an individual first probe request message includes an encoding of corresponding beam steering direction from the number of beam steering directions;
an Omni-antenna to listen, in a second mode, for second probe request messages transmitted by the device;
a receiver to receive at least two first probe response messages in response to sequential transmission of the first probe request messages; and
logic to generate a vector of signal strengths, distances, and angles for an individual beam steering direction according to information in the at least two first probe response messages and the first and second probe request messages.
