shreshtha writes: GreenTouch, a global industry consortium formed by Alcatel-Lucent Bell Labs, has said its research shows the net energy consumption in the world's information and communication technology (ICT) networks could be reduced up to 90 percent by 2020, if a number of leading-edge technologies are adopted. Key technologies e.g. small cells deployment in dense urban environments, infrastructure sharing, discontinuous transmissions during periods without traffic, bit interleaved passive optical networking, dynamic resource allocation to diurnal traffic fluctuations, energy efficient hardware and network equipment.
The consortium's goal at creation was to help create the technologies that would make communications networks 1,000 times more energy efficient than they were in 2010 to provide headroom for the increase in data traffic to come. Energy efficiency is defined as the ratio of the useful traffic carried by a network and the total energy required to support that traffic over a year.
This is a great initiative forcasting the steep growth of network and traffic.

The South Korean giant said the test had witnessed data transmission of more than one gigabyte per second over a distance of two kilometres. The new technology, which will not be ready for the commercial market before 2020 at the earliest, would offer transmitting speeds "up to several hundred times faster" than existing 4G networks, it said in a statement.

The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered by these batteries to jump-start a dead car battery – and then recharge the phone in the blink of an eye. The new microbatteries offer both power and energy, and by tweaking the structure a bit, the researchers can tune them over a wide range on the power-versus-energy scale.
hypnosec writes: The yet to be released Linux 3.7 kernel is getting exciting by the day prior to its release as it has been announced that the kernel will be supporting multiple-ARM System on Chips (SoCs) / platforms. Up until now there is a separate Linux kernel build for each of the ARM platform or SoCs, which is one of the several problems when it comes to ARM based Linux. The merging of ARM multi-platform support into Linux 3.7 will now put an end to this problem thus enabling the new kernel to not only target multiple platforms but, also be more in line with its x86 counterpart.
shreshtha writes: Apple proposed a reciprocal patent agreement to Samsung in the months leading up to their landmark trial, but the two could not arrive at a deal acceptable to both companies.
Apple is willing to license its declared-essential UMTS patents to Samsung on license terms that rely on the price of baseband chips as the FRAND royalty base, and a rate that reflects Apple's share of the total declared UMTS-essential patents (and all patents required for standards for which UMTS is backward-compatible, such as GSM)--provided that Samsung reciprocally agrees to this same, common royalty base, and same methodological approach to royalty rate, in licensing its declared-essential patents to Apple. Apple estimates that this approach, which implements the true meaning of and requirements imposed by FRAND, results in a $.33 (thirty-three cents) per unit royalty for the Apple patents. Apple will today license its declared-essential UMTS patents to Samsung at that rate, provided Samsung reciprocally agrees to the FRAND principles that result in that rate. This rate would be applied to all Samsung units that Apple has not otherwise licensed. Samsung would likewise need to agree that it would only charge royalties on Apple units that Samsung has not otherwise licensed.

The firm has made a tunable, steerable RF antenna using micro-electro-mechanical-system (MEMS) which it says will change all that. It's based on research from Edinburgh University and is designed to get the best our of LTE/4G."
shreshtha writes: Engineers from Elbrus Technologies are working on special software that would enable programs written for x86 architecture microprocessors to run on systems powered by chips with architecture from ARM Holdings. In case the emulation software proves to be efficient, it could give ARM a huge boost on the market of servers. Many companies nowadays, including Applied Micro, Calxeda, Cavium, Marvell, Nvidia and Samsung, are developing server-class ARM-architecture processors. However, the impact that such chips can have on server market is relatively limited as they cannot run mainstream programs designed for x86 chips made by Advanced Micro Devices or Intel Corp. The emulation software of Elbrus Technologies currently delivers 40% of native ARM performance. The company believes it could reach 80% native ARM performance or greater by the end of 2014.
Even with these forward steps, considering the fact that ARM-based central processing units (CPUs) are generally slower than x86 chips, the emulation software is still not absolutely the best way to drive ARM processors into servers.

AMD, Oracle and other members of the OpenJDK community are forming Project Sumatra to help bring heterogeneous computing capabilities to Java for server and cloud computing environments.
This primary goal of this project is to enable Java applications to take advantage of graphics processing units (GPUs) and accelerated processing units (APUs)--whether they are discrete devices or integrated with a CPU--to improve performance.
shreshtha writes: Below article tells that Intel unveiled a digital Wi-Fi radio which can be manufactured in situ with digital processor chips (and not separate analog chips). Intel's Palaskas explains that a digital Wi-Fi radio that takes up 1.2 millimeters of chip space will draw 50 milliwatts of power. The same radio design compressed into an area of 0.3 millimeters (manufactured with so-called 32-nanometer processes) will only sip 21 milliwatts. This is comparable to the best radios made mostly out of analog components, says Palaskas.
Rabaey suggests that in the future, multiple digital radios could be combined into one, which could reduce the cost of making cell phones. Instead of separate components for 3G, 4G, Wi-Fi, Bluetooth, and other radios, a single chip could contain all of them.

Dr. Harold “Sonny” White, of NASA’s Johnson Space Center, was able to significantly reduce the amount of energy required by altering the shape of the ring around the ship from flat to more of a rounded donut. With this ship may travel at 10 times the speed of light without the ship itself ever breaking the speed of light. www.space.com/17628-warp-drive-possible-interstellar-spaceflight.html
shreshtha writes: The way multi core work on shared data presently cannot be scaled to say 100 of cores.
Li-Shiuan Peh, an associate professor of electrical engineering and computer science at MIT, wants cores to communicate the same way computers hooked to the Internet do: by bundling the information they transmit into “packets.” Each core would have its own router, which could send a packet down any of several paths, depending on the condition of the network as a whole. Not only do the researchers establish theoretical limits on the efficiency of packet-switched on-chip communication networks, but they also present measurements performed on a test chip in which they came very close to reaching several of those limits.
shreshtha writes: Magnetic hard disks will soon be able to store one terabit (a trillion bits) per square inch. Seagate has demonstrated that landmark storage density using a new magnetic recording method that can cram 10 terabits, and perhaps even more, onto every inch of a standard 3.5-inch disk. Disks made with current technology can hold about 3 terabytes.
The technology, called heat-assisted magnetic recording, involves heating the magnetic regions on a disk that hold individual data bits, allowing those regions to be made tinier. Seagate says the method promises to keep increasing storage density, and it could lead to 60-terabyte hard drives.
