interference

The Federal Communications Commission has proposed a fine of $48,000 against a Seffner, FL man who allegedly jammed consumer cell service from his car over a two year period. 

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.

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.

This 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.

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.
