TV antenna for WIFI?
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 ... more than 1, 6 kilometers (one mile).
The idea is to provide internet to those households that are blocked from internet access is in some cities due to the height of the trees, mountains or other obstacles.
The testing was done in a house that could not 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.
Guerra is part of a research team working on the development of Internet transmissions over unused TV space.
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.
Guerra calls the project super WiFi and the system takes the normal WiFi signals and shifts them over to the TV station frequency. The student has already tested the system in a home where the cities free WiFi signals didn’t reach thanks to lots of tall trees surrounding the property. Super WiFi could get the single to the home even though it was a mile from the All Wi-Fi transmission tower that sent the free broadband service.
The system that Guerra designed uses components like an off the shelf 2.4GHz WiFi card on a Linux computer and the card’s frequency was connected to a frequency translator developed by Alcatel Lucent. This is the key bit of magic that downshifts the WiFi signals to the empty channels in the 563MHz frequency. The output from the translator was connected to a TV antenna set up outside the home.
