How can this _possibly_ work? You can't make a connection to Wifi or implement any of the protocols that run over by passively reflecting some signals. All of them require some processing and two way communication. The article just makes no sense at all. It is 1st April?
- justusthane 9y agoIt's explained in the article, although the title is inaccurate. The 3D printed devices do not, themselves, connect to WiFi. The backscatter is picked up by a WiFi receiver which is connected to the WiFi. But if you're going to comment, why not take the time to understand the article instead?
- TeMPOraL 9y agoThey use of "Wi-Fi" is itself a lie. It's not using Wi-Fi anymore than it's using Bluetooth or Zigbee. It's scattering back EM frequencies that happen to include 2.4GHz, which is a standard frequency for most consumer-level wireless communication.
- jbb67 9y agoI read and understood the article fully thank you. Wifi does not work like that and this cannot possibly work.
- teraflop 9y ago"this cannot possibly work" -- are you claiming that the working prototype depicted in the video is a fraud? That's a very serious allegation.
