China Producing World’s Largest Radio Telescope

 

A large engineering and scientific project in China, led by the country’s military-led space program, is creating the world’s largest radio telescope, which will be able to detect radio signals from tens of billions of light years away. The Telescope is known as FAST, which stands for Five-hundred-meter Aperture Spherical Telescope. When the project is complete, the dish on the … [Read more...]

‘Electrosmog’ to Help Power Devices in UK

 

Paul Drayson, a former British science minister, has developed a device that captures “electrosmog” (invisible clouds of electromagnetic radiation), and uses it to power small devices. The energy-harvesting system is known as Freevolt. Freevolt uses an antenna to gain power from multiple wavebands of the electromagnetic spectrum. This is the first commercial device that is … [Read more...]

High School Students and UPenn Professor Build Radio Telescope in West Philadelphia

 

This past summer, as part of UPenn’s Summer Science Academy Program, 12 high school students along with James Aguirre, associate professor in the School of Arts & Sciences’ Department of Physics and Astronomy, turned an out-of-service TV satellite dish on the roof of the Enterprise Center in West Philadelphia into a 30-foot radio telescope. The telescope has been given the … [Read more...]

India Launches Space Observatory into Orbit to Study Electromagnetic Spectrum

 

On Monday, Sept. 28 at 12:30 a.m. EDT, The Indian Space Research Organization (ISRO) successfully launched seven satellites into orbit from the Satish Dhawan Space Centre (SDSC) in Sriharikota, India. One of the satellites is the country’s first ever space observatory. This mission, known as PSLV-C30, lasted about 23 minutes and 32 seconds. “The most important passenger of the … [Read more...]

First U.S. Public School District Limits Wi-Fi Radiation Exposure

 

Ashland, Massachusetts Public Schools have announced they will be reducing Wi-Fi radiation exposure to students and teachers via Wi-Fi Device “Best Practices.” “Spurred by parent Cecelia Doucette's concerns about the lack of safety data on Wi-Fi and children, the district investigated the issue and developed a policy to substantially reduce wireless exposures to students and … [Read more...]

Company Presented with Award for Work with Vector Network Analyzers

 

Frost & Sullivan presented Copper Mountain Technologies (CMT) with the 2015 Global Frost & Sullivan Award for Competitive Strategy Innovation and Leadership for the company’s work in the Vector Network Analyzer (VNA) market. “CMT's VNAs stand out for their high performance in a smaller form factor at much lower prices than existing mid-range network analyzers. While … [Read more...]

Canadian Police to Receive New Radio System after EMI Issues

 

Sault Ste. Marie Police are preparing for a new radio system, since their current system, which is 15 years old, experiences communication problems and constant radio frequency interference. However, police dispatchers still have problems ahead. “Motorola is phasing out support the console's main components. The withdrawal of assistance starts in 2016 and ends in 2018,” … [Read more...]

How do you measure 5G?

 

By Lars Jacob Foged   The development of 5G cellular networks is well underway and requires a new approach to ensure accurate measurement of the antenna components. With flexible radiation patterns which are capable of adapting to the changing situations in mobile networks, the full characterisation of the Active Antenna System (AAS) in 3D space has been the focus of … [Read more...]

‘Radiogate’ Controversy in First NFL Game – Pittsburgh Experienced EMI in Helmets

 

Last night, during the NFL season opener in New England between the New England Patriots and the Pittsburgh Steelers, a technology malfunction reportedly caused the Patriot’s radio broadcast to air on the headsets of the Steelers’ coaches during the entire first half of the game. The nickname ‘Radiogate’ has surfaced – a play on the Patriot’s previous ‘Deflategate’ controversy … [Read more...]

RFID Sensors Allow for the Collection of Football Data

 

The NFL has joined with Zebra Technologies to launch MotionWorks RFID sensors, which will be placed in the shoulder pads of all the players. “The sensors will each emit unique radio frequencies that will be captured by the 20 receivers that have been put in all the stadiums that are used by the NFL,” according to the Tech Times. Through these sensors, data about the players … [Read more...]
