Noise interference is the menace of all wireless broadcast communications services
Background noise interference is degrading the quality of broadcast reception, two-way communications, mobile cellphone services and every other form of wireless communications used today at an alarming rate.
The FCC and the ITU agree that the DC to 60 GHz+ wide-spectrum background noise floor is increasing as more and more unregulated electronic devices are used by more consumers in more ways every day.
While it is true that large numbers of these devices have been in use for some time, the question becomes: What can we do to lower the noise floor now that the floodgates of unregulated devices have been open for so long? Is this an impossible task? I believe the answer is an emphatic “no.”[…]

In all these cases — one in Mount Vernon, N.Y., one in Dallas and three in a single location in East Orange, N.J. — the FCC reiterated that operating radio transmitting equipment at certain levels without a valid station is against the law, ordered them all to shut down, laid out the potential ramifications and gave each a window in time for them to explain their actions in writing.
Pirate radio has been a renewed point of concern for broadcasters in the United States, with recent debate over the possible impact of cuts in field offices and with Commissioner Michael O’Rielly keeping a spotlight on the problem.

OTTAWA — On Jan. 31, state-owned Australian Broadcasting Corp. shut down its shortwave radio transmitters; ending both international broadcasts of Radio Australia and the ABC’s domestic service in Australia’s Northern Territory. The transmitters were located at ABC broadcasting facilities at Katherine, Tennant Creek, and Roe Creek (Alice Springs).
