TL;DR: The proposed Tagyro, which attaches an array of passive RFID tags as orientation sensors on everyday objects, uses a closed-form model to transform the run-time phase offsets between tags into orientation angle, and can track the 3D orientation of passive objects with a small error.

TL;DR: Pia is proposed, a robust 60 GHz network architecture that can provide seamless coverage and mobility support at multi-Gbps bitrate and reduces the occurrence of link outage by 6.3x and improves the spatial sharing capacity by 76%, compared to conventional schemes that only use in-band information for adaptation.

TL;DR: This paper proposes a model-driven 3D beam-steering mechanism called Orthogonal Scanner (OScan), which can maintain high performance for mobile 60 GHz links in 3D space and discovers and leverages a hidden interaction between 3D beams and the spatial channel profile of 60 GHz radios, and strategically scans the3D space to reduce the search latency by more than one order of magnitude.

TL;DR: Software-radio based implementation and testbed experimentation show that Signpost significantly outperforms state-of-the-art user selection methods under various traffic patterns and node mobility.
