NFL Institutes New Digital Communication System for Playcalling
After three decades in play, the NFL is dropping the old analog system used by coaches to relay plays to their quarterbacks and instituting a new digital communication system instead. The old analog systems faced heavy interference from concerts and airlines that often interrupted vital communications, as well as poor sound quality and communication delays. The new digital … [Read more...]
New Service Stops Interference of Wireless Devices with Military Radar
One of the world's leading experts in product testing and certification, TÜV SÜD Product Service, launched the United Kingdom’s first Dynamic Frequency Selection (DFS) service that utilizes a single-test platform. The new single-test platform was designed and made in the UK by Aeroflex. The new TÜV SÜD system is up to 60 percent faster than traditional methods of DFS testing … [Read more...]
Request for Shared Radio Waves in Europe Will Benefit Data Services
As Web use rapidly increases and available space remains limited, the European Commission is pushing reluctant telecoms companies to share the radio frequencies they use for mobile and broadband services. Many companies that own parts of the radio wave spectrum consider that ownership to be one of their most valuable assets and so, have been reluctant to share. As a finite … [Read more...]
Charge Your Cell Phone with Yourself
A professor at Wakeforest University’s Centre for Nanotechnology and Molecular Materials has developed a system that allows users to charge their own cell phones with their body heat. The "Power Felt" allows phones to remain charged up to 20 percent longer using body heat as electricity to charge the phone. “I have an excess of electrons on one side, and a depletion of excess … [Read more...]
Space Satellite to Improve Telecom Completes EMC Testing
Sierra Nevada Corporation’s Space Systems has successfully completed critical EMC testing of ORBCOMM Inc.’s Generation 2 (OG2) prototype satellite. The ORBCOMM OG2 will serve as a prototype for a total of 18 new satellites that will constitute the company’s second generation satellite network. They are designed to improve telecommunication services as well as collect Automatic … [Read more...]
Proposals Sought for Pulsed Lasers to Control Electromagnetic Spectrum
DARPA seeks proposals for solutions concerning pulse lasers for use as low phase noise microwave oscillators for secure communications among other applications. Pulsed lasers are known as frequency combs because they are composed of thousands of individual laser lines, equally separated in frequency like the teeth of a comb. DARPA is looking for methods of efficiently … [Read more...]
