Simple Ham Radio Antennas

Many antennas, multiple benefits : " Many antennas , multiple benefits", Jan 21, 2015 By combining large distributions of compact antenna nodes with fast fiber optic communication, researchers have developed a new wireless infrastructure ready for intense future demands. Credit: A* A*STAR Institute for Infocomm Research A concept that balances large-scale installations of low-cost and low-power antennas to boost cellular coverage in difficult environments will also provide better connectivity to more users. Developed by A*STAR, this new architecture for wireless communications can help service providers meet growing demands for increased network capacity and improved energy efficiency. Jingon Joung, Yeow Chia and Sumei Sun from the A*STAR Institute for Infocomm Research in Singapore sought to combine two state-of-the-art wireless technologies into a novel type of antenna system. The first technology, known as large-scale multiple-input multiple-output (L- MIMO ), use...

- How will the 5G network change the world? - via Eagle Averro - Newsvine : 1 December 2014 How will the 5G network change the world? By Ed Ram BBC News The global race is on to develop 5G, the fifth generation of mobile network. While 5G will follow in the footsteps of 4G and 3G, this time scientists are more excited. They say 5G will be different - very different. If you're thinking, "Great, that's the end of my apps stalling, video faltering, and that everlasting load sign," then you are right - but that's only part of the story. "5G will be a dramatic overhaul and harmonisation of the radio spectrum," says Prof Rahim Tafazolli who is the lead at the UK's multimillion-pound government-funded 5G Innovation Centre at the University of Surrey. That means the opportunity for properly connected smart cities, remote surgery, driverless cars and the "internet of things". So, how best to understand this joined-up, superfast, ...
