Student use television antennas to increase range of WiFi network

Ryan Guerra, a graduate student at Rice University, devised a method to extend the reach of WiFi networks using unused TV signals. The project is called "Super WiFi" and is to change the frequency of Internet signal, allowing it to be transmitted in the television spectrum, increasing its reach to more than 1.6 kilometers (one mile). The idea is to provide internet to those households that are blocked from the internet is free in some cities due to the height of trees, mountains or other obstacles. Testing was done in a house that was not enough to connect because of the tall trees that were outside. However, using "Super WiFi" signal was able to enter the house. This is even more interesting when one considers that the vivienva was more than 1.5 kilometers from the transmission tower. War is part of a research team that is working on the development of internet transmissions through space without using TV. To achieve the test make it work, Guerra used a standard WiFi card connected to a frequency translator, developed by Lucent Alcaltel. Finally, the translator was connected to a TV antenna to connect to WiFi.

  4. Hey that's interesting. I always thought about building an own antenna and experiment with it.
