I promise you I am not trolling read page 242:12 on WIFI INPUT WIDGETS. It explicitly states it sends packets. http://printedwifi.cs.washington.edu/printedwifi

I promise you I am not trolling read page 242:12 on WIFI INPUT WIDGETS. It explicitly states it sends packets. http://printedwifi.cs.washington.edu/printedwifi.pdf http://printedwifi.cs.washington.edu/printedwifi.pdf Achieving data communication using push buttons requires us to address two unique challenges: 1) we need a mechanism to identify the beginning of a packet, and 2) since users can push buttons at different speeds, we need an algorithm for symbol synchronization.

On page 242:5, it explicitly says that it doesn't send new packets. > In our case, the backscatter signal is a narrowband transmission embedded on top of the ambient Wi-Fi signals, since the printed Wi-Fi objects send data at a low data rate. Even your quoted text doesn't say that it sends packets IMO.

  Please explain how it works in as simple terms as you can? My explanation: The 3D printed Wifi device uses plastic and metal to connect to any Wifi receiver (normal laptop or smartphone) using any commercially available Wifi transmitter. 3D device uses it's antenna to send new data. The data is sent uses reflection and absorption of the Wifi signal to create new data of 1s and 0s though at a slower rate of speed. This is all done without the need for batteries or other electronics. There is no special hardware or software besides the 3D device to connect and send data. The device can toggle an electronic switch to either absorb or reflect an ambient signal to convey a sequence of 0 and 1 bits using reflective and non-reflective states. This is accomplished by leverages present Wifi backscatter technology but for the first time instead of using electronic components these 3D devices use non-electronic and printable analogues. > "embedded on top of the ambient Wi-Fi signals," That is how backscatter works and how they connect to wifi and send specific 1s and 0s. It absorbs and reflex a wifi signal out of those absorption and reflections. It can't work without some signal to carry on top of it and could work with a single 2.4 sine wave. But backscatter absolutely sends measurements to a normal Wifi rx aka a phone or laptop through the Wifi transmitter.
