This project is about building a portable dual band WiFi analyzer that help you see through the invisible RF world and understand the WiFi signal in your household.

With a SPI LCD display, you can bring it to any room and location, and start scanning the environment.

The image displayed on the screen is dynamic , inlcuding WiFi signal strength, channel, and name , with each WiFi signal colored differently. Thus as you roam around a house or building, you will be able to see WiFi signal changing dynamically, revealing the WiFi signal in your close proximity.
