Three perytons in January coincided with independently detected blasts of 2.4
gigahertz radio waves — the same frequency
At radio frequencies greater than 10
gigahertz the radio emission matched that of the microwave background, but at lower frequencies it was several times stronger.

Today the picture of the
radio spectrum is a color - coded colossus composed of hundreds of bands allotted by the FCC from frequencies as low as 6 kilohertz to as high as 300
gigahertz.
Wi - Gig requires higher
radio wave frequencies, though: 60
gigahertz rather than the 2.4 GHz used by Wi - Fi.
I borrowed one that could detect signals from 100 kilohertz (kHz), just below the frequency of long - wave
radio stations, up to 3 gigahertz (GHz), somewhat above the 2.4 GHz portion of the spectrum used by Wi - Fi connections (see «Radio Ways,» be
