Automatic antenna sector-level sweep in an IEEE 802.11ad system

Techniques for performing automatic antenna sector-level sweep switching are described herein. According to an embodiment, an apparatus comprises a lookup table for storing a set of antenna configuration entries and a sector-level sweep (SLS) controller implemented in hardware that is communicatively coupled to the lookup table. The SLS sweep controller is operative to read an antenna configuration entry from the set of antenna configuration entries stored in the lookup table and output control signals to configure a set of one or more antennas based on the antenna configuration entry. The SLS controller is further operative to switch between different antenna configuration entries in the set of antenna configuration entries stored in the lookup table in response to a signal from a timing source thereby periodically changing the configuration of the set of one or more antennas.
