下一代无线和移动的网络将利用毫米波(mmWave)通信来实现显著增加的数据速率。然而,由于毫米波无线电信号经历高路径损耗,毫米波网络的操作将需要为特定部署站点设计的精确信道模型。在本文中,我们专注于在纽约市的PAWR COSMOS试验台[1,2]的部署区域,并报告了广泛的28 GHz信道测量。其中包括2019年3月至6月期间从3个不同地点的13条人行道上的1,500多个链接中收集的2,400多万个功率测量结果。使用这些测量,我们研究了设置和环境的影响(例如,发射机高度和季节效应)。然后,我们讨论了获得的路径增益值和它们的拟合线,以及由此产生的有效方位波束形成增益。基于这些结果,我们还研究了链路SNR值,可以支持个人的人行道和相应的理论上可实现的数据速率。我们相信,这些结果可以为COSMOS测试平台部署过程提供信息,并为密集城市地区的其他部署工作提供基准。
Next generation wireless and mobile networks will utilize millimeter-wave (mmWave) communication to achieve significantly increased data rates. However, since mmWave radio signals experience high path loss, the operation of mmWave networks will require accurate channel models designed for specific deployment sites. In this paper, we focus on the deployment area of the PAWR COSMOS testbed [1, 2] in New York City and report extensive 28 GHz channel measurements. These include over 24 million power measurements collected from over 1,500 links on 13 sidewalks in 3 different sites and in different settings during March-June, 2019. Using these measurements, we study the effects of the setup and environments (e.g., transmitter height and seasonal effects). We then discuss the obtained path gain values and their fitted lines, and the resulting effective azimuth beamforming gain. Based on these results, we also study the link SNR values that can be supported on individual sidewalks and the corresponding theoretically achievable data rates. We believe that the results can inform the COSMOS testbed deployment process and provide a benchmark for other deployment efforts in dense urban areas.
