5G与4G主用频段空口损耗差异浅析

Analysis on the Passloss Difference in Main Frequency Band Between 5G and 4G

针对5G与4G网络规划中覆盖差异及损耗问题,通过理论分析和精确、严格的测试,对5G网络主用频段3 500 MHz与4G网络主用频段1 800 MHz进行了对比,得出5G与4G网络天线口EIRP相同的情况下的空口损耗差异,较现有引用的方法修正了约5.39 dB,并提出该差异值的计算和测试方法及应用建议,为5G/4G的网络方案及策略的制定提供参考。

Aiming at the problem of coverage difference and loss in 5G and 4G network planning,it compares the main frequency band 3500 MHz of 5G network with 1800 MHz of 4G network through theoretical analysis and precise and strict test,and obtains the passloss difference under the same EIRP of 5G and 4G network antenna port,which is about 5.39 dB modified compared with the existing methods,and puts forward the calculation and test methods and application suggestions of the difference value standard,which provides reference for 5G/4G network scheme and strategy.
