Employer Fined $29K by FCC for Illegally Using a Cell Phone Jammer

The FCC has issued a fine of $29,000 to R&N Manufacturing, Ltd (RNM) for repeated violations of operating a signal jammer at its manufacturing facility in Houston, TX. The illegal use of the jammer caused interference to cellular and PCS communications in the area that could cause potential public safety hazards.

Wireless Technology Uses Interference to Enhance Mobile Internet

A new wireless technology is being developed that makes better use of the wireless spectrum and uses a different approach than current wireless technology. This new technology, pCell, uses signal interference where signals overlap and create small personal mobile internet cells.

Efficient Suppression of Interference in Modules at the Developer’s Workplace

1405 F2 coverThis article deals with improving EMC measuring methods that are used during the development of automobiles in the field of interference emissions. Development-stage investigations are normally performed with measuring systems that have actually been conceived for vehicle component tests. EMC measuring methods that are tailored to the development stage, however, are much better suited for this task since they help save time and costs. One such measuring method is presented here as a practical example.

A Tall Tale: What’s Luck Got to Do With It?

Rising above the tidal marshes of Southern New Jersey stands a red and white antenna tower shadowing a World War II era radio shack. The marsh was a simple mosquito nursery in the 40s when the first modest building—a cinder block foundation and stick-framed walls— was erected as part of a string of radio stations that formed a wartime network on the East Coast. German subs prowled the waters just off the shore of Cape May which hosted just a few houses and one general store with peeling gray paint and sway-back roofline.

Update on CISPR Standards: What’s New Above 9 kHz

The global recession has not prevented EMC standardization work from marching relentlessly forward. Work within CISPR is no exception and this year delegates and experts will meet in Lyon, France in September under the auspices of the current chairman Don Heirman (US) and secretary Steve Colclough (UK). For those of you new to EMC, CISPR is an international special committee on radio interference within the International Electrotechnical Commission (IEC). As defined on the IEC website for CISPR, CISPR’s principal task is at the higher end of the frequency range, from 9 kHz upwards, preparing standards that offer protection of radio reception from interference sources such as electrical appliances of all types, the electricity supply system, industrial, scientific and electromedical RF, broadcasting receivers (sound and TV) and, increasingly, IT equipment (ITE). Following is a brief overview of the scope of CISPR’s current activities in 2009, close to 75 years after its founding in 1935.

US vs Recent Canadian Rules for Ultra-Wideband Radio Operations

With the publication of Industry Canada RSS-220 in March of this year, manufacturers are now able to certify and market their UWB (Ultra-Wideband) equipment in Canada. Following the publication of FCC (Federal Communications Commission) UWB rules in Part 15 Subpart F by 7 years, the new RSS-220 rules largely follow FCC equipment categories and limits. However, the Industry Canada limits are more stringent in part than the FCC’s for hand held and indoor communication devices. Test methods and equipment labeling also differ somewhat between the FCC and IC rules.
