How much havoc is caused by unwanted radio signals? FCC tries to find out

The Federal Communications Commission is trying to figure out exactly how much trouble is being caused by radio noise.

Many devices emit radio frequency energy that could interfere with radio services and increase the “radio spectrum noise floor,” essentially the sum of all unwanted signals. The FCC is planning a study examining changes to the noise floor from human-made sources over the past 20 years.

It’s commonly believed that “the noise floor in the radio spectrum is rising as the number of devices in use that emit radio energy grows,” but the FCC said it hasn’t found much quantitative data to support this presumption. As a first step toward the FCC producing such a study, the commission last week asked the public for input on the proper design of the study and input on the problem itself.
