A new communications satellite aims to ease the strain of overcrowded communications networks in Latin America, while adding capacity to direct-to-home services in Canada and military users across the Americas. http://phys.org/news285316047.html Space & Earth Tue, 16 Apr 2013 07:27:36 EST news285316047 Military radars, military communications networks, and commercial communications networks all require increasing amounts of limited radio frequency spectrum. Balancing national security requirements of radars and military networks with the growing bandwidth demands of commercial wireless data networks calls for innovative approaches to managing spectrum access. DARPA's Shared Spectrum Access for Radar and Communications (SSPARC) program aims to improve radar and communications capabilities for military and commercial users by creating technical solutions to enable spectrum sharing. http://phys.org/news279798193.html Technology Mon, 11 Feb 2013 09:43:24 EST news279798193 (Phys.org)—The closer you live to another person, the more likely you are to be friends with them despite the growing use and impact of social media, according to a study that drew on data from the location-based social network provider Gowalla. The study, by researchers within the Social Cognitive Network Academic Research Center (SCNARC) at Rensselaer, also showed that people tend to move in groups of friends, and that two people chosen at random at a specific event (like a concert or at a particular store) are unlikely to be friends. http://phys.org/news274095330.html Technology Fri, 07 Dec 2012 09:40:03 EST news274095330 Myanmar fired the starting gun in the process of liberalising its communications networks in a move that could finally bring mobile and Internet access to the masses and drive international investment. http://phys.org/news261139533.html Technology Tue, 10 Jul 2012 11:45:45 EST news261139533 (Phys.org) -- The decks have arrived. Engineers working on NASA'S Magnetospheric Multiscale (MMS) mission have started integrating instruments on the first of four instrument decks in a newly fabricated cleanroom at Goddard Space Flight Center in Greenbelt, Md. The MMS mission consists of four identical spacecraft, and each instrument deck will have 25 sensors per spacecraft. http://phys.org/news258397714.html Space & Earth Fri, 08 Jun 2012 18:08:38 EST news258397714 The overall performance of modern computers and communications networks is dependent on the speed of electronic components, such as transistors and optical switches, as well as the quality of the wire network that powers and relays signals between these electronic components. Power and signal integrity are two important parameters for gauging the quality of a wire network, but simulating these parameters for next-generation electronic systems can take a considerable amount of time, particularly when there is a large number of components involved. Zaw Zaw Oo at the A*STAR Institute for High Performance Computing and co-workers have now significantly decreased the amount of computer time needed by developing a modelling technique that is much more efficient. http://phys.org/news252228189.html Technology Thu, 29 Mar 2012 08:23:30 EST news252228189 (AP) -- Telecommunications company Zayo Group said Monday it will acquire AboveNet Inc. for $2.2 billion.

As a result, this enormous thirst for moving pixels is fast outpacing the capacity to supply video to viewers' screens. http://phys.org/news228722648.html Technology Fri, 01 Jul 2011 07:08:34 EST news228722648 (PhysOrg.com) -- Researchers have achieved a breakthrough in quantum communications and computing using a teleporter and a paradoxical cat. http://phys.org/news222074638.html Physics Fri, 15 Apr 2011 08:24:16 EST news222074638 Epson Toyocom Corporation, a leader in crystal devices, today announced the development of a new series of differential-output SAW oscillators that offer both excellent stability and high-frequency oscillation, from 100 MHz and up. Measuring just 5.0 mm x 3.2 mm along the edges and only 1.4 mm thick, the SAW oscillators in the new EG-2121/2102CB series are believed to be the smallest of their type in the world. Samples are currently available for evaluation. Commercial development is scheduled for December 2011. http://phys.org/news219398547.html Technology Tue, 15 Mar 2011 09:03:07 EST news219398547 Cuban authorities are accusing the United States of waging "cyberwar" against the communist-ruled island -- an effort that Havana claims includes an American contractor on trial for espionage. http://phys.org/news218865318.html Technology Wed, 09 Mar 2011 03:55:40 EST news218865318 (PhysOrg.com) -- Natasha Devroye, University of Illinois at Chicago assistant professor of electrical and computer engineering, has won a five-year, $450,000 National Science Foundation Early Faculty Career Award to aid in her work analyzing communication flow by way of mathematical models. http://phys.org/news216572345.html Technology Thu, 10 Feb 2011 14:59:39 EST news216572345 As computing power continues to move from the desktop to portable devices, the nature of communications networks will change radically. A network in which devices are regularly being added and removed, and where the strength of the connections between the devices fluctuates with their movement, requires much different protocols from those that govern relatively stable networks, like the Internet. http://phys.org/news211183628.html Technology Fri, 10 Dec 2010 06:40:02 EST news211183628 Keyboard warriors from the United States and a dozen other nations were battling a simulated cyber attack Tuesday on government and private networks that undermines basic trust in the Internet. http://phys.org/news204864505.html Technology Tue, 28 Sep 2010 03:48:38 EST news204864505 (AP) -- Twitter Inc. has announced - in a tweet, of course - that it will build a huge data center in Utah, making it the latest company to set up computer-intensive operations in a state with cheap electricity and a business-friendly reputation. http://phys.org/news199036522.html Technology Thu, 22 Jul 2010 17:20:02 EST news199036522 For centuries, "man-made fibers" meant the raw stuff of clothes and ropes; in the information age, it's come to mean the filaments of glass that carry data in communications networks. But to Yoel Fink, an Associate professor of Materials Science and principal investigator at MIT's Research Lab of Electronics, the threads used in textiles and even optical fibers are much too passive. For the past decade, his lab has been working to develop fibers with ever more sophisticated properties, to  enable fabrics that can interact with their environment. http://phys.org/news198144512.html Nanotechnology Mon, 12 Jul 2010 09:40:02 EST news198144512 Finland on Thursday became the first country in the world to make access to a broadband service a basic right, ensuring that a high-speed Internet connection is available to all Finns, a government official said. http://phys.org/news197220152.html Technology Thu, 01 Jul 2010 16:30:01 EST news197220152 A radical new approach to the design of communications networks, called "network coding," promises to make Internet file sharing faster, streaming video more reliable, and cell-phone reception better -- among other improvements. http://phys.org/news184924443.html Technology Tue, 09 Feb 2010 08:40:05 EST news184924443 (PhysOrg.com) -- It may look like little more than fishing line, but plastic optical fibre or POF promises to revolutionise high-speed last-mile communications networks.
