Edge-based caching and blockchain-nodes speed up data transmission
The combination of a blockchain-like distributed network, along with the ability to locate data at the edge will massively speed up future networks, such as those used by the internet of things (IoT), claims Bluzelle in announcing what is says is the first decentralized data delivery network (DDN).Distributed DDNs will be like content delivery networks (CDNs) that now cache content around the world to speed up the web, but in this case, it will be for data, the Singapore-based company explains. Distributed key-value (blockchain) networks and edge computing built into Bluzelle's system will provide significantly faster delivery than existing caching, the company claims in a press release announcing its product.To read this article in full, please click here

Will 5G be the first carbon-neutral network?
If wireless networks transfer 1,000 times more data, does that mean they will use 1,000 times more energy? It probably would with the old 4G LTE wireless technologies— LTE doesn’t have much of a sleep-standby. But with 5G, we might have a more energy-efficient option.More customers want Earth-friendly options, and engineers are now working on how to achieve it — meaning 5G might introduce the first zero-carbon networks. It’s not all certain, though.[ Related: What is 5G wireless? And how it will change networking as we know it ] “When the 4G technology for wireless communication was developed, not many people thought about how much energy is consumed in transmitting bits of information,” says Emil Björnson, associate professor of communication systems at Linkoping University, in an article on the school’s website.To read this article in full, please click here

The first step toward ultra-high-speed Wi-Fi: a laser-radio transmitter
Leaping toward the next generation of wireless-based data communications, researchers say they are making progress extracting and sending data using semiconductor lasers that churn out radio signals across multiple frequencies all at the same time. Data could conceivably be transmitted hundreds of time faster than today’s traditional Radio Frequency (RF) wireless, engineers believe.It’s the “first laser-radio transmitter,” Harvard University proclaims of its invention in an article on its John A. Paulson School of Engineering and Applied Science (SEAS) website.To read this article in full, please click here

Revolutionary data compression technique could slash compute costs
There’s a major problem with today’s money-saving memory compression used for storing more data in less space. The issue is that computers store and run memory in predetermined blocks, yet many modern programs function and play out in variable chunks.The way it’s currently done is actually, highly inefficient. That’s because the compressed programs, which use objects rather than evenly configured slabs of data, don’t match the space used to store and run them, explain scientists working on a revolutionary new compression system called Zippads.The answer, they say—and something that if it works would drastically reduce those inefficiencies, speed things up, and importantly, reduce compute costs—is to compress the varied objects and not the cache lines, as is the case now. Cache lines are fixed-size blocks of memory that are transferred to memory cache.To read this article in full, please click here

How data storage will shift to blockchain
If you thought cloud storage was digging in its heels to become the go-to method for storing data, and at the same time grabbing share from own-server, in-house storage, you may be interested to hear that some think both are on the way out. Instead organizations will use blockchain-based storage.Decentralized blockchain-based file storage will be more secure, will make it harder to lose data, and will be cheaper than anything seen before, say organizations actively promoting the slant on encrypted, distributed technology.[ Read also: Why blockchain (might be) coming to an IoT implementation near you ] Storing transactional data in a blockchain China company FileStorm, which describes itself in marketing materials as the first Interplanetary File Storage (IPFS) platform on blockchain, says the key to making it all work is to only store the transactional data in blockchain. The actual data files, such as large video files, are distributed in IPFS.To read this article in full, please click here

Extreme 5G network research gets funding
Wireless transmission at data rates of around 45 gigabits per second could one day be commonplace, some engineers say. “Fiber-in-air” is how the latest variant of 5G infrastructure is being described. To get there, a Britain-funded consortium of chip makers, universities, and others intend to aggressively investigate the exploitation of D-Band. That part of the radio spectrum is at 151-174.8 GHz in millimeter wavelengths (mm-wave) and hasn’t been used before.The researchers intend to do it by riffing on a now roughly 70-year-old gun-like electron-sending device that can trace its roots back through the annals of radio history: The Traveling Wave Tube, or TWT, an electron gun-magnet-combo that was used in the development of television and still brings space images back to Earth.To read this article in full, please click here

Anti-lasers could give us perfect antennas, greater data capacity
Playing laser light backwards could adjust data transmission signals so that they perfectly match receiving antennas. The fine-tuning of signals like this, not achieved with such detail before, could create more capacity for ever-increasing data demand."Imagine, for example, that you could adjust a cell phone signal exactly the right way, so that it is perfectly absorbed by the antenna in your phone," says Stefan Rotter of the Institute for Theoretical Physics of Technische Universität Wien (TU Wien) in a press release.To read this article in full, please click here

Running LEDs in reverse could cool computers
The quest to find more efficient methods for cooling computers is almost as high on scientists’ agendas as the desire to discover better battery chemistries.More cooling is crucial for reducing costs. It would also allow for more powerful processing to take place in smaller spaces, where limited processing should be crunching numbers instead of making wasteful heat. It would stop heat-caused breakdowns, thereby creating longevity in components, and it would promote eco-friendly data centers — less heat means less impact on the environment.Removing heat from microprocessors is one angle scientists have been exploring, and they think they have come up with a simple, but unusual and counter-intuitive solution. They say that running a variant of a Light Emitting Diode (LED) with its electrodes reversed forces the component to act as if it were at an unusually low temperature. Placing it next to warmer electronics, then, with a nanoscale gap introduced, causes the LED to suck out the heat.To read this article in full, please click here

Motorola taps CBRS spectrum to create private broadband LMR system
In a move that could upend how workers access data in the enterprise, Motorola has announced a broadband product that it says will deliver data at double the capacity and four-times the range of Wi-Fi for end users. The handheld, walkie-talkie-like device, called Mototrbo Nitro, will, importantly, also include a voice channel. “Business-critical voice with private broadband data,” as Motorola describes it on its website.The company sees the product being implemented in traditional, moving-around, voice communications environments, such as factories and warehouses, that increasingly need data supplementation, too. A shop floor that has an electronically delivered repair manual, with included video demonstration, could be one example. Video could be two-way, even.To read this article in full, please click here

Data center fiber to jump to 800 gigabits in 2019
The upper limits on fiber capacity haven't been reached just yet. Two announcements made around an optical-fiber conference and trade show in San Diego recently indicate continued progress in squeezing more data into fiber.In the first announcement, researchers say they’ve obtained 26.2 terabits per second over the roughly 4,000 mile-long trans-Atlantic MAREA cable, in an experiment; and in the second, networking company Ciena says it will start deliveries of an 800 gigabit-per-second, single wavelength light throughput system in Q3 2019.High-speed laser MAREA, translated as “tide” in Spanish, is the Telefónica-operated cable running between Virginia Beach, Va., and Bilbao in Spain. The fiber cable, initiated a year ago, is designed to handle 160 terabits of data per second through its eight 20-terabit pairs. Each one of those pairs is thus big enough to carry 4 million high-definition videos at the same time, network-provider Infinera explains in an Optical Fiber Conference and Exhibition published press release.To read this article in full, please click here

The noise in fiber could be used to increase data capacity
Increasing the capacity of fiber-optic cables might one day be possible through the exploitation of a part of the signal commonly thought of as substandard. That imperfect element in a carrier, called “noise” is usually something one tries to avoid—it can muddy the accurate reading of the data.However, scientists now suggest that one could, in fact, embrace the rubbishy, and thus far unusable, part of the signal to hold data and allow it to be decoded. The ordinarily data-obscuring hubbub could potentially be harnessed and used to increase data capacity in light waves.“Information is encoded in the correlated noise between spatially separated light waves,” writes Oliver Morsch in an article on the website of ETH Zurich, a technical and scientific university. “The new coding technology, developed by ETH researchers, makes it possible to make better use of the transmission capacity of optical fibers.”To read this article in full, please click here

How blockchain will manage networks
Ethernet networking technology is flawed, say some engineers. The problem is it doesn’t have any inherent security built in to it. Ethernet also hard to manage because it's centralized. It’s out-of-date, and it needs revamping, researchers say.One attempt to address the issue is the Marconi protocol, which is a strategy to shift network and packet management over to a smart contract, decentralized chain-based system. Smart contracts are trackable, verifiable transactions. They’re performed through encrypted blockchains and are self-enforcing.To read this article in full, please click here
