Modelling Human-Body Effects on Indoor Multiple-Input Multiple-Output Channels for Broadband Wireless Systems

多输入多输出(MIMO)技术使用多个天线来发送多个信号，以此来显著提高无线网络的速度、范围和可靠性。即将出台的IEEE802.11n标准在其规范中包括多输入多输出，其覆盖范围将是现有IEEE 802.11产品的8倍，速度将达到现有IEEE 802.11n产品的6倍。通过全面的测量活动，该项目将表征在人口稠密的环境中，例如繁忙的工商业建筑中，人体对室内MIMO系统的时变影响。结果将直接影响未来的无线应用，从科学和经济增强的角度来看都是有价值的。

Multiple-Input Multiple-Output (MIMO) technologies use a number of antennas to send multiple signals as a way to significantly increase the speed, range and reliability of a wireless network. The upcoming IEEE 802.11n standard, which includes MIMO in its specifications, will offer up to eight times the coverage and up to six times the speed of currently available IEEE 802.11 products. Through comprehensive measurement campaigns, this project will characterise the time-varying human body effect on indoor MIMO systems in populated environments, such as busy industrial and commercial buildings. Results will have a direct impact on future wireless applications, and are valuable from both scientific and economy-enhancement viewpoints.
