Military Radio Frequencies May Interfere with Garage Door Openers

 

Remote-control garage door openers near the Blue Grass Army Depot in Richmond K.Y. may stop working due to military radio systems switching to a new frequency range. The U.S. military will switch all land mobile radios (LMRs) to new frequencies, which are also the same frequencies used by certain unlicensed consumer devices, like garage door openers. These frequencies have … [Read more...]

Blog Asks: Are Cell Phones Harmful to Human Health?

 

Electromagnetic radio frequencies emitted from cell phones and other electronic devices remains a topic of debate due to possible health concerns. Cell phones produce low levels of non-ionizing radiation. Thus far, “extensive research into the health effects of these devices has only produced inconclusive evidence,” according to VOA News. The wireless industry and other … [Read more...]

China’s Railway System Receives ‘Smart Station’ Upgrade

Woman Fights Cancer with Electric Fields

 

Elizabeth Marek, a mother of two from St. Louis Missouri, has a deadly form of brain cancer known as Glioblastoma, which has no cure and a life expectancy of two years after diagnosis. A small tumor was found in her brain after she started experiencing aggressive headaches, and surgeons at Washington University removed the tumor in an emergency surgery. Eventually, a second … [Read more...]

Electromagnetic Fields Could Delay Alzheimer’s Disease in Rats

 

A team of researchers in China have published a study that suggests exposure to extremely low frequency electromagnetic fields (ELF-EMF) delays the development of Alzheimer’s Disease (AD) in rats. The study, titled “Improvement of Spatial Memory Disorder and Hippocampal Damage by Exposure to Electromagnetic Fields in an Alzheimer’s Disease Rat Model” was published in the … [Read more...]

FCC’s Plan to Revitalize AM Radio Concerns Listeners

 

On May 15, iHeartMedia met with the FCC Media Bureau to discuss the current plan to revitalize AM Radio and to discuss an ex parte letter describing possible changes to AM radio stations. The plan in place will reduce skywave interference protection which make it easier for AM radio stations to operate and give users more flexibility. Jeff Littlejohn of EVP/Engineering and … [Read more...]

Anti-jamming Technology Effective in Protecting Satellites from Interference

 

Boeing Engineers have tested an anti-jamming technology for satellites that shields signals from interference and have proven the technology is capable of operating both on the ground and in a satellite-based networking hubs. The test was completed under a contract for the U.S. Air Force Space and Missile Systems Center and was supervised by the U.S. Government. It was … [Read more...]

Astronomers Discover 17-Year Interference Caused by Microwave Oven

 

For nearly 17 years astronomers at Parkes Observatory in Australia searched for the reason why radio interference took place during experiments and observations. They discovered early this year that the interference was coming from a microwave oven in the observatory’s kitchen. Parkes Observatory houses one of the best-known radio telescopes in the country. It is used to … [Read more...]
