A Radio World article highlights the growing RF 
pollution problem which is ruining peoples' enjoyment of radio .

Broadcast engineers are becoming more aware of 
the impact of environmental radio noise on 
reception. The recent efforts at ?AM improvement? 
have highlighted this challenge to AM stations, 
and evidence is growing that reception on FM and 
TV bands is being impaired as well.

The general public, however, is far less aware of 
our growing noise pollution issue. Listeners or 
viewers may not know why there is a reception 
problem; they just perceive the signal as ?weak? 
and may switch to a competitor. Broadcasters are 
hearing a common pattern in listener complaints: 
?I used to get good reception, but not anymore??
I wrote about this in Radio World in a 2011 
article ttitled ?Johnston Laments FM Noise.?

Other industries using RF wireless technologies 
report growing noise trouble as well. A recent 
IEEE Spectrum article was subtitled ?Electronic 
Noise Is Drowning Out the Internet of Things.? 
Designers of IoT devices are not getting the 
range they expect due to unexpectedly high background noise, it reported.
