Wi-Fi网站调查:被动,主动,RTLS

分享💚

We’ve已经在几篇博客文章中讨论了Wi-Fi网站调查( 基本 何时进行现场调查)。但是,并非所有现场调查都是平等的。那里’可以执行的三种常见的现场调查类型:

被动现场调查

执行以了解现场的RF特性。所谓射频特性,是指Wi-Fi信号强度,噪声水平,SNR(信噪比)等。进行现场调查的原因“passive” is that your Wi-Fi network adapter is pretty much just listening to packets when performing 被动 site surveys. OK, the NIC might send some probes out, but that’s about it.

活动现场调查

提供有关网络连接性和/或性能的更多信息。数据包丢失,数据包延迟和访问点之类的东西’可以在活动站点调查期间进行测量。顾名思义,通过主动测量,Wi-Fi适配器正在接收和发送数据包以找出’网络的真正发展。

RTLS站点调查(aka RTLS校准调查)

执行以使用Wi-Fi(需要定位引擎和Wi-Fi标签)启用高精度资产和人员跟踪。它’s hard to get good accuracy with Wi-Fi RTLS without surveying the site first. From the technical perspective, RTLS site survey is similar to a 被动 survey.

在部署,验证或优化网络时,应该始终执行前两个调查中的两个。仅当考虑或部署RTLS时,才需要进行RTLS调查。

Many Wi-Fi tools only support one kind of a survey (typically 被动). Some provide more options, but only allow you to perform one type of a survey at a time. I typically try not to advertise 叶卡豪products too much on this blog, but: To save on-site time, 叶卡豪Site Survey supports making all three at once. Let’s看到我们的竞争对手需要多长时间才能赶上这一…

下次我们应该谈论RTLS或Wi-Fi设计/管理吗?对博客主题有什么建议吗?
