TL;DR: Borealis is a system that provides accurate directional guidance and leads users to a desired AP after a few measurements that is significantly more accurate than other real-time localization systems, and is nearly as accurate as offline approaches using extensive wireless measurements.

TL;DR: A new distributed angle estimation method for localization in wireless sensor networks (WSNs) under multipath propagation environment is proposed using a two-antenna anchor that can emit two linear chirp waves simultaneously and the angle of departure of the emitted waves is estimated at each receiving node via frequency measurement of the local received signal strength indication (RSSI) signal.

TL;DR: In this paper, a frequency synchronization scheme for multiuser orthogonal frequency division multiplexing uplink with a large-scale uniform linear array at base station (BS) by exploiting the angle information of users is proposed.

TL;DR: This paper explores the feasibility of a new wireless primitive for data centers, 3D beamforming, and shows how bouncing 60 GHz wireless links off reflective ceilings can address both link blockage and link interference, thus improving link range and number of current transmissions in the data center.

TL;DR: This paper proposes a frequency synchronization scheme for multiuser orthogonal frequency division multiplexing uplink with a large-scale uniform linear array at base station (BS) by exploiting the angle information of users to perform carrier frequency offset estimation for each user individually through a joint spatial-frequency alignment procedure.
