Putting Physics to Work: Boosting Wireless Antenna Signal with Box Reflector

When you live in the middle of nowhere, such as Russia or some Chicago suburbs, you don't have many options for broadband internet. Thankfully, Clear rolled-out their 4g WiMax network in Chicagoland last November, and so I was finally able to make the switch from dial-up internet.

However, it wasn't the best reception, displaying only 1-2 bars. I tried making parabolic dishes with some success, but overall it was cumbersome. The most effective and efficient solution was a box reflector (PDF).

A simple cardboard box, aluminum foil, and tape. Just 10 minutes later, the modem displayed 4/5 bars compared with 1-2/5 bars!



Displayed modem: Motorola CPEi 150
