I’m a couple days late in posting this, but this is huge news. Not requiring a dongle or hub for IoT devices is the way it should be.
801.11ac, or 5G Wi-Fi, is backwards compatible with a/b/g/n standards, and promises a significant speed boost compared to 802.11n. From Wikipedia:
Theoretically, this specification will enable multi-station WLAN throughput of at least 1 Gigabit per second and a maximum single link throughput of at least 500 megabits per second (500 Mbit/s).
Better WiFi security could soon be just a few rolls of wallpaper away. French researchers at Institut Polytechnique de Grenoble, in cooperation with the Centre Technique du Papier, have developed a wallpaper that can block WiFi signals, preventing them from being broadcast beyond the confines of an office or apartment.
Unlike other types of signal-blocking materials, this one lets cellphones and other radio waves through. Ars Technica’s article mentions that the wallpaper should be available for sale sometime in 2013; I found out that the Finnish manufacturer licensing the technology is Ahlstrom.
