XKCD: Centimeter Wavelengths

Title text: "Yes, the cosmic microwave background is great, but what about the earthly microwave foreground?"

Penzias and Wilson, while debugging the noise in their cm wavelength antenna accidentally discovered the cosmic microwave background radiation. They won the Nobel Prize in 1978.

What about IT people who spend endless hours troubleshooting WiFi that uses similar wavelengths?
