室外的繁殖大小在远处象 awide 乐队一样竞选 3G (B3G ) 室内的测量运动最近在中国北京,发出声音的信号由一个一个天线库车站在被播送并且由在 3.49 ~ 3 .51 GHz 带宽操作的二天线的活动接收装置收到了被执行了。不同情形:静止 line-of-sight (LoS ) ,静止 non-LoS (NLoS ) 情形,和动态 NLoS 故意在经典城市的环境和办公室环境被选择。起始的结果在这篇文章被介绍。Parametersincluding 向量隧道推动反应,路径损失,光线数,过量延期传播等等这里被提取,分析,并且简短报导了。
An outdoor propagation measurement campaign for beyond 3G (B3G) as well as a wide-band indoor measurement campaign have been performed recently in Beijing, China, in which the sounding signals are transmitted by an one-antenna base station and received by a two-antenna mobile receiver operated at 3.49~3.51 GHz bandwidth. Different scenarios: stationary line-of-sight (LoS), stationary non-LoS (NLoS) scenarios, and dynamic NLoS are deliberately chosen in a classic urban environment and office environment. The initial results are presented in this article. Parameters including vector channel impulse response, path loss, rays number, excess delay spread etc. are extracted, analyzed, and briefly reported here.
