While GPS-based outdoor localization has become a norm, very few indoor systems have been deployed and used. In this paper, we share our 5-year experience on the design, development evaluation of large-scale WiFi system. We address practical challenges encountered to bridge gap between research in laboratory system deployment wild. The is currently used 1469 shopping malls, 393 office buildings 35 hospitals across cities provide location service millions users daily basis. hope shared can...
A heterogeneous medium access control (MAC) scheme (with both scheduled and random communications) is proposed for airborne networks. These networks have a hierarchical topology with small number of powerful aircraft nodes multibeam antennas long-distance links at the higher level, high-density unmanned aerial vehicle (UAV) single-beam directional lower level. Our MAC has following three parts: First, multibeam, to links: dynamic, take advantage features achieve high-throughput...
By using the multibeam smart antennas (MBSAs), nodes can form a high-throughput wireless mesh network with concurrent packet delivery in multiple directions. In this paper, novel medium access control (MAC) scheme is designed for airborne networks. It has following two features: First, IEEE 802.11-compatible, interference-minimized channel via special two-layer MAC architecture, where upper-layer supports transmission/reception, and lower-layer takes advantage of MBSAs; second, adjustment...
In this paper an indoor positioning system is presented based on 77GHz frequency modulation continuous wave (FMCW) radar. The uses AWR1843 chip, and designs antenna module, power module program memory module. Based the traditional signal processing chain, a method of distance estimation velocity estimation, followed by Angle proposed. Through distance, angle information target, function can be realized.
During the rehabilitation training, methods of gait analysis and planning are very important.We must consider simplicity implementation validity method used.Combined with ultra-wideband wireless body area network, gyroscopes, acceleration sensors TOA positioning technology, we proposed a that is also effective in three-dimensional space.After summarizing existing analysis, point out shortcomings commonly based video motion capture advantages sensor networks.Then, propose for three...
