Abstract

In this research we present the measured path loss values in typical urban and suburban areas at the operating frequency of 3.5 GHz. The measurements are carried out using the spectrum analyzer FSH6 in order to record the channel response. The values of path loss exponent n are calculated for urban and suburban environments. We also compare and analyze the path loss predictions with the measured data. The results of this research confirm that in urban areas the path loss estimation is influenced according to the greater distances. At the beginning of the measurements in urban environment the losses are equal 23 dB after 18 m from the measurement survey. The analysis of measurements centers on anticipating the normal signal quality at the collector set at the given remove from the transmitter as well as the changeability of the signal quality in the specific environment. The acquired from this work results are salutary for planning and installation of any base station with similar to the thoughtful locations environments in order to supply rules for cell arranging of remote communication frameworks as path loss could be a key in calculations within the plan of any radio communications framework system.

3.5 GHz 室外蜂窝通信系统的传播测量和路径损耗指数计算

摘要

在本研究中，我们展示了在 3.5 GHz 工作频率下典型城市和郊区的路径损耗测量值。使用频谱分析仪 FSH6 进行测量以记录信道响应。路径损耗指数 n 的值是针对城市和郊区环境计算的。我们还将路径损耗预测与测量数据进行比较和分析。这项研究的结果证实，在城市地区，路径损耗估计会受到更远距离的影响。在城市环境中开始测量时，距离测量调查 18 m 后的损耗等于 23 dB。测量分析的中心是预测在给定距离的发射器处的收集器组的正常信号质量以及特定环境中信号质量的可变性。从这项工作中获得的结果对于规划和安装任何具有类似于周到位置环境的基站都是有益的，以便为远程通信框架的小区布置提供规则，因为路径损耗可能是任何无线电计划中计算的关键通信框架系统。
