![]() The 2.4GHz ISM (Industrial Scientific Medical) band is often called the WiFi band because it is used for WiFi networking (ie, 802.11 b/g/n). This project was inspired by an article by Jason Hecker in the June 2007 issue of Elektor. Total cost to build it should be less than US$30. ![]() It uses just two significant components, a radio module from Cypress Semiconductor and a PIC microcontroller. It connects to your computer by USB 2.0 and with the companion Windows software you can display the spectrum or save the raw data to an Excel compatible file for some more number crunching. Just what is out there? This neat little gadget will sniff the airwaves and give you a graph of the signal strength vs frequency across the entire band. What channel is it best to set your wireless router to? Why are you getting such poor performance across your WiFi network? Is your neighbour on the same frequency? Have you ever wondered exactly what is going on in the 2.4GHz WiFi and ISM band around your house. ![]() This work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Australia (CC BY-NC-SA 3.0)
