wifi穿墙-阿里云

牛科技：通过wifi穿墙透视

本文讲的是牛科技：通过wifi穿墙透视，不必羡慕超人拥有X射线视力的本领，现在你也可以，只需要通过wifi设备就能看到墙的另一边。麻省理工学院计算机科学人工智能实验室（Computer Science and Artificial Intelligence Lab，简称为CSAIL）已经开发出了一...

5G WiFi的信号难题：穿墙性能太差

首先得抱歉下，5G WiFi的稿子拖了这么久，宅客微信后台的更新俺都有看到，这篇来了。接着上篇，我们从多方面对比了2.4GHz和5GHz WiFi的特点，因而得出了“因房制宜”的频段选择方法。但对5GHz频段来说，并不能简单看wikipedia的室内信号传输距离的数据，还需要更细致的...

WiFi黑科技？麻省理工用WiFi穿墙认人

黑科技往往是指超越现今人类科技或知识所能涉及的范畴，同时缺乏当前的科学根据或违反自然原理的科学技术或者产品，但却又让人感到相当炫酷的产物。近日，麻省理工学院(MIT)计算机科学和人工智能实验室就对外发布了一项在一般人看起来有些“黑科技”意味的技术——用WiFi来识别人。麻省理工学院利用WiFi可以...

全新WiFi技术问世功率更低穿墙性能更强

据美国媒体报道，WiFi似乎已经将消费者家中的大多数设备都连在一起了，那为什么不通过它将智能家电也都连在一起呢？虽然这样的想法看似理所当然，但是实际上大多数连网设备厂商一直不愿意使用WiFi，这主要是因为WiFi的耗电量太大了，因此对于很多廉价的微型设备来说，这就是一个巨大的问题。这些微型设备充一...
