FCC Commissioner Cites Need and Interference Mitigation Strategies in Push to Save AM Radio
Once the dominant method of broadcasting for much of the 20th century, AM radio is in increasing danger of extinction. Already overlooked by listeners in favor of FM, Internet and satellite radio services, AM radio is now facing an additional threat in the form of rising interference from smartphones and other consumer electronics. According to the Federal Communications … [Read more...]
Technology Adjusts Femtocell Transmissions to Prevent Interference
Fujitsu Laboratories Ltd. and Fujitsu Laboratories of America, Inc. have announced the development of technology that reduces radio interference by analyzing the environment around a femtocell and adjusting its transmissions accordingly. Often placed in locations where macrocell coverage is limited in some way, such as inside a home or small business, femtocells are small … [Read more...]

TVS Array Protects Computing Applications from ESD and EFT
Semiconductor company ProTek Devices has released a new low capacitance transient voltage suppressor (TVS) array designed to protect computing applications from the damaging effects of electrostatic discharge (ESD) and electrical fast transients (EFT). “At higher operating frequencies or faster edge rates, insertion loss and signal integrity are a major circuit protection … [Read more...]
FCC Announces Rule Change for 60 GHz Band
The Federal Communications Commission (FCC) has announced a rule change regarding the high frequency 57-64 GHz band in a decision that could bring faster, more cost-effective broadband services to both rural and urban areas. FCC acting chairman Mignon Clyburn and commissioners Jessica Rosenworcel and Ajit Pai unanimously approved changes to the commission’s Part 15 rules last … [Read more...]
U.S. Navy Tests Military Spectrum Sharing Potential
The U.S. Navy has taken a large step towards opening military frequencies for greater commercial use with a recent experiment that evaluated whether or not military and commercial devices can successfully share the same frequency without interference. In a recent test off the coast of Virginia's eastern shore, the Navy activated an AN/SPY1—a powerful naval radar system that … [Read more...]
