IT needs to make mobile unified communications a priority

The need for safe, reliable, and easy-to-use communications tools has given rise to unified communications (UC), a strategy that integrates multiple communications modalities under a single management and security umbrella. The result is more effective communication, improved collaboration, and a boost to security and regulatory policies. Now that mobility is the primary networking vehicle for end users, it’s time for IT departments to make mobile unified communications (MUC) a priority.The most important benefit of MUC is the ability of organizations to finally leave behind the uncontrolled, untracked mish-mash of consumer-centric, carrier, and third-party communications tools traditionally applied over the years. Communications are a critical organizational resource; MUC is a much easier vehicle to manage and scale, and MUC offers the visibility and control that’s essential to enterprise IT deployments. These advantages will enable MUC to become the dominant provisioning strategy and mechanism for organizational communications over the next five to 10 years.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

Startups introduce new liquid cooling designs

With the increase in compute density making air cooling less and less feasible, liquid cooling is going mainstream. For data centers. Overclockers have been doing it for years.For the most part, liquid cooling involves piping in cooled water to a heat sink attached to the CPU. The water then cools the heat sink, and is pumped away to be circulated and cooled down.But there are some cases where immersion is used. That is where the entire motherboard is submerged in a nonvolatile liquid. Immersion is used in only the most extreme of cases, with the highest compute density and performance. For a variety of reasons, it isn’t widely used.One startup that hopes to change that showed its wares at the Open Compute Project Summit 2019, which ran last week in San Jose. The OCP has a special project called Advanced Cooling Solutions to promote liquid cooling and other advanced cooling approaches.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

Wearable tech in the enterprise grows, but few workplace uses exist

Take a glance at the wrists of your co-workers, and you’re likely to see more and more of them adorned with smartwatches, fitness trackers, and other wearable technology. In meetings, you increasingly see colleagues surreptitiously glancing at their tiny screens, hoping in vain that no one is noticing.It isn’t just you. The latest smartwatch numbers all say that smartwatch shipments are growing fast, and the internet-connected devices are beginning to achieve mainstream acceptance: Last month, The NPD Group's new Smartwatch Total Market Report noted that smartwatch unit sales jumped 61 percent in 2018, while dollar volume rose 51 percent to approach $5 billion in sales. Some 16 percent of U.S. adults now own a smartwatch, the report said, up from 12 percent at the end of 2017.To read this article in full, please click here

How to determine if Wi-Fi 6 is right for you

There’s a lot of hype around the next Wi-Fi standard, 802.11ax, more commonly known as Wi-Fi 6. Often new technologies are built up by the vendors as being the “next big thing” and then flop because they don’t live up to expectations. In the case of Wi-Fi 6, however, the fervor is warranted because it is the first Wi-Fi standard that has been designed with the premise that Wi-Fi is the primary connection for devices rather than a network of convenience.Wi-Fi 6 is a different kind of Wi-Fi Wi-Fi 6 is loaded with new features, such as Orthogonal Frequency Division Multiple Access (OFDMA), 1024-QAM (quadrature amplitude modulation) encoding and target wake time (TWT), that make Wi-Fi faster and less congested. Many of these enhancements came from the world of LTE and 4G, which solved many of these challenges long ago. These new features will lead to a better mobile experience and longer client battery life, and they will open the door to a wide range of new applications that could not have been done on Wi-Fi before. For example, an architect could now use virtual reality (VR) over Wi-Fi to showcase a house.To read this article in full, please Continue reading
