2.4 GHz WiFi Spectrum Analyser
What’s happening in your area?
Published in issue 366, June 2007
This project takes advantage of certain parts of the circuitry in a 2.4GHz digital radio chip to make a simple spectrum analyser. This can give you a picture of which parts of the 2.4 GHz WiFi spectrum are being used in your immediate vicinity and even be used as an aid in optimising channel use and detection of interfering devices.
R1-R4 = 10kΩ
R5-R8 = 15kΩ
D1,D2,D3 = 1N4001
MOD1 = Cypress module type CYWM6935
K1 = 25-way sub-D plug (male), angled pins, PCB mount
K2 = USB-B connector
