Wind/Solar WiFi Hotspot - This 8-Bit Life

Leland Flynn

This was originally reported by the folks @ Hack-a-Day but I thought it was too cool not to post. The students @ the Rochester Institute of Technology built a WiFi Hotspot using a parabolic antenna that repeats a signal it picks up from a nearby building. The parabolic antenna that grabs the signal is about 19dBi and the Omnidirectional that broadcasts the signal to the surrounding area is about 8dBi. This is all powered by a 90V DC wind turbine and a 30W solar panel, these both charge 2 6V batteries in series.

This is a pretty excellent idea. They’ve extended the effective range of their wifi over a quarter of a mile to a separate node and best of all they don’t have to pay for power!


Here’s the link to the Hack-a-Day post.
