Abstract
An approach to acquisition of a propagation direction using a phased antenna array avoids a need to scan space. Given all possible directions for setting the antenna beam, the approach provably finds the optimal direction in logarithmic number of measurements. Further, the approach can be applied within the existing 802.11ad standard for mmWave LAN, and can support both clients and access points.
