It'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.
