Abstract (EN): To improve range, 802.11ad uses directional communication, the first step of which is to choose the best antenna configuration, or sector. We studied the sector selection behavior of Commercial Off-The-Shelf (COTS) 802.11ad equipment in an experimental Vehicle-to-Infrastructure (V2I) communication scenario. Analysis of the collected data revealed the following inefficiencies: (i) a large number of sector selection attempts that do not result in a sector change; and (ii) a ping-pang effect in which a node oscillates between two sectors. With this in mind we studied an alternative antenna sector selection scheme that uses spatially-indexed historical performance data to pick the statistically-best sector for any given geolocation. A trace-based analysis showed that such a strategy can potentially improve throughput by up to 60 %, depending on location.
