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...]

Invisibility Cloak to Improve Military Operations

 

A team of scientists from the University of California, San Diego (UCSD) have developed a material that resembles an invisibility cloak. The material could change the face of military operations and would allow weapons and maybe even military personnel to function while undetected. UCSD scientists have tested the “first effective dielectric metasurface material—an ultra-thin, … [Read more...]

Apple’s First Electric Car to Surface in 2019

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.

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...]

Magnetic Field Cloak to Assist MRI Scanners and Medical Industry

 

Scientists from the Autonomous University of Barcelona have created a magnetic field cloak, or ‘wormhole,’ which could lead to better MRI scanning. “The wormhole allows a magnetic field to be transported across space but it is not the kind of cosmic tunnel popularised by science fiction. Rather, the magnetic field at one end of the wormhole appears at the other end as an … [Read more...]
