技术资料 Understanding_the_Basics_of_MIMO
An acronym for Multiple-In, Multiple-Out, MIMO communication sends the same data as several signals
simultaneously through multiple antennas, while still utilizing a single radio channel. This is a form of
antenna diversity, which uses multiple antennas to improve signal quality and strength of an R ...

技术资料 5G移动通信天线的研究与设计
所设计的多频段小型化天线结构新颖，性能指标优越，与当前国内外研究的大多数同类天线相比保持较小体积，在多频、宽频工作频段上也保持较强的竞争力。其中所设iMonopole，780MHz-1010MHz和1630MHz3900MHz，在高频频段上的提升相当明显，与大多数同类天线相比提升超过100%，除了覆盖GSM，UMTS，LTE的频段外，还覆盖WiMAX的频 ...
技术资料 无线802.11n 2.4G与5G性能测试
在传输速率方面，802.11n可以将WLAN的传输速率由目前802.11a及802.11g提供的54Mbps，提高到300Mbps甚至高达600Mbps.得益于将MIMO（多入多出）与OFDM（正交频分复用）技术相结合而应用的MIMO OFDM技术，提高了无线传输质量，也使传输速率得到极大提升。现有的802.11n无线AP/路由设备主要是150M和300M产品，这两种产品的实用 ...
技术资料 5g移动通信系统简介
5G，第五代移动通信技术，也是4G之后的延伸，目前正在研究中。目前还没有任何电信公司或标准订定组织（像3GPP，WiMAX论坛及ITU-R）的公开规格或官方文件有提到5G。按照业内初步估计，包括5G在内的未来无线移动网络业务能力的提升将在3个维度上同时进行：1）通过引入新的无线传输技术将资源利用率在4G的基础上提高10倍以上； ...
