This cable significantly limits the player's mobility and, hence, her VR experience. The high data rate requirement of this link (multiple Gbps) precludes its replacement by WiFi. Thus, in this paper, we focus on using mmWave technology to deliver multi-Gbps wireless communication between VR headsets and their game consoles. We address the two key problems that prevent existing mmWave links from being used in VR systems. First, mmWave signals suffer from a blockage problem, i.e., they operate mainly in line-of-sight and can be blocked by simple obstacles such as the player lifting her hand in front of the headset. Second, mmWave radios use highly directional antennas with very narrow beams; they work only when the transmitter's beam is aligned with the receiver's beam. Any small movement of the headset can break the alignment and stall the data stream. We present MoVR, a novel system that allows mmWave links to sustain high data rates even in the presence of a blockage and mobility. MoVR does this by introducing a smart mmWave mirror and leveraging VR headset tracking information. We implement MoVR and empirically demonstrate its performance using an HTC VR headset.","PeriodicalId":240202,"journal":{"name":"Proceedings of the 1st ACM Workshop on Millimeter-Wave Networks and Sensing Systems 2017","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115341580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently proposed mmWave network standards, like 802.11ad, have spawned a new wave of applications such as wireless virtual reality and uncompressed miracast. However, due to ultra-high carrier frequency, the 60 GHz radios are extremely vulnerable to propagation loss and obstacle blockage. To combat the intrinsic signal attenuation, the use of highly directional phased-array antennas, with limited Field-of-view (FoV), makes the mmWave links extremely sensitive to user mobility and orientation change. Hence, achieving stable 60 GHz connectivity, even at room-level, becomes a nontrivial task. My research has been focusing on a series of techniques to address these challenges. These techniques leverage extraneous sensing information to facilitate the mmWave protocols, so as to provide room-scale coverage at multi-Gbps bit-rate. In this talk, I will first outline the impact of limited FoV of the 60 GHz radio under mobility, and then present a robust 60 GHz network architecture, in which multiple cooperating APs can complement others' blind spots and together form seamless coverage. I will then describe two design components: pose-assisted link predictor and pose-assisted spatial sharing. They leverage the pose information from mobile devices, and improve the 60 GHz network robustness under mobility through intelligent AP switching and beam selection. Finally, to account for the impact of reflections from close-by objects, I will introduce an environment sensing method, which fuses the pose information with the link quality measurement, to computationally discriminate the refection paths and model their impacts separately.","PeriodicalId":240202,"journal":{"name":"Proceedings of the 1st ACM Workshop on Millimeter-Wave Networks and Sensing Systems 2017","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131447247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nodes should steer their beams such that they maximize the signal gain but also minimize interference from lateral directions via both their main lobe and their side lobes. Most importantly, interference can be caused by parallel operation of incompatible standards such as WiGig and IEEE 802.11ad and may change very fast. This timing requirement, prevents the use of existing beam switching solutions to mitigate interference. In this paper, we present an adaptive beam switching (ABS) mechanism that can deal with the above timescale issue in rapidly changing interference scenarios. Instead of performing a full beam sweep, the key idea is to only probe beampatterns at the receiver which are likely to avoid interference. In contrast to earlier work, our mechanism does not require any location information nor a detailed shape of the beampatterns. We exploit similarities among side lobes of beampatterns to estimate the performance of all beampatterns without sending extensive probes. To evaluate our mechanism in practice, we develop a customized research platform that allows us to control the beam-selection on low-cost IEEE 802.11ad routers. Experimental results with WiGig transceivers as interference source show that our adaptive beam switching mechanism achieves an average throughput gain of 60% and decreases the training time by 82.4% compared to the original IEEE 802.11ad behavior.","PeriodicalId":240202,"journal":{"name":"Proceedings of the 1st ACM Workshop on Millimeter-Wave Networks and Sensing Systems 2017","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130830672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
