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

IEEE Spectrum article was subtitled Electronic

Designers of IoT devices are not getting the
range they expect due to unexpectedly high background noise, it reported.
