Infrared technology offers faster wireless data transfer than Wi-Fi and Bluetooth

By - October 2, 2012 1 Picture
Back around the turn of the century, infrared ports for wireless data transfer over short distances were commonplace on many mobile devices. But it wasn't long before infrared communication technology was kicked to the curb in favor of the more versatile radio-based Wi-Fi and Bluetooth technologies. Fraunhofer researchers are looking to resurrect infrared wireless data transfer technology with the development of a “multi-gigabit communication module” that can wirelessly transfer data 46 times faster than Wi-Fi and 1,430 times faster than Bluetooth.

Intel demos WiGig wireless technology that is 10 times faster than 802.11n

By - September 16, 2012 1 Picture
Many home and business local area networks (LANs) built around the 802.11n standard are starting to buckle under the strain placed on them by an ever-increasing number of wireless devices clamoring for bandwidth. A new technology known as WiGig is looking to clear the bottleneck by offering transfer rates 10 times that of the fastest 802.11n networks. At its Intel Developer Forum (IDF) 2012 in San Francisco, Intel demonstrated WiGig multigigabit wireless docking technology that has the potential to remove almost all wires trailing to and from a computer.

Optical communications system and autonomous microscope to boost underwater research

By - July 30, 2012 6 Pictures
It would definitely be an understatement to say that underwater research has its technical challenges. Remote-operated vehicles (ROVs) must be tethered to surface support vessels with unwieldy communications cables, deep-sea water samples have to be hauled to the surface for analysis ... or do they? Woods Hole Oceanographic Institution recently announced that it has partnered with two private companies, to market a couple of technologies that address both of those situations. Read More

Sony's new XQD S Series memory cards outperform Compact Flash

By - July 4, 2012 1 Picture
Despite numerous other format developments, Compact Flash has remained the memory card of choice for many of today's photography professionals. It's reliable, rugged and a good size for quick swap overs during shoots. CF is also a good deal faster than other media trying to break into the pro market. The addition of UltraDMA Mode 7 in Revision 6.0 took the format's maximum read/write speed up to 167 MBps but Sony has now managed to nudge ahead with the launch of its faster XQD S Series memory cards.

Data transmission speed of 2.56 Tb/s achieved by twisting beams of light

By - June 26, 2012 1 Picture
Thankfully, data transmission speeds have come a long way since the days of dial-up when users would have plenty of time to twiddle their thumbs as they waited for an image or MP3 to make its way to their hard drive. These days, broadband cable currently supports speeds of around 30 megabits per second, which is a hell of an improvement. Now researchers have outdone that by a factor of around 85,000 by using twisted beams of light to transmit data at up to 2.56 terabits per second. Read More

IBM looks to new technologies for unprecedented data processing challenge

By - April 2, 2012 3 Pictures
When completed in 2024, the Square Kilometre Array (SKA) will be the largest, most sensitive radio telescope ever created. It will consist of 3,000 individual ground-based dish antennas, linked to act as one big telescope – an arrangement known as an interferometer. While their combined total surface area will be about one square kilometer (0.39 sq mile), they will be spread out across a geographical area approximately 3,000 kilometers (1,864 miles) in width. They will be gathering about one exabyte of astronomical data per day, which is twice the amount of data that is handled by the World Wide Web on a daily basis. Today, IBM announced that it has partnered with ASTRON (the Netherlands Institute for Radio Astronomy), in an effort to develop computer systems that will be able read, analyze and store all of that data, and do so in an energy-efficient manner.

IBM unveils one trillion bit-per-second optical chip

By - March 12, 2012 2 Pictures
Last Thursday at the Optical Fiber Communication Conference in Los Angeles, a team from IBM presented research on their wonderfully-named “Holey Optochip.” The prototype chipset is the first parallel optical transceiver that is able to transfer one trillion bits (or one terabit) of information per second. To put that in perspective, IBM states that 500 high-def movies could be downloaded in one second at that speed, while the entire U.S. Library of Congress web archive could be downloaded in an hour. Stated another way, the Optochip is eight times faster than any other parallel optical components currently available, with a speed that’s equivalent to the bandwidth consumed by 100,000 users, if they were using regular 10 Mb/s high-speed internet.

Hybrid fiber optic cable carries data and power

By - February 3, 2012 1 Picture
When you want to isolate communications between two devices or locations, a fiber optic link is one of the best ways to go. Under some circumstances, however, you might also want to isolate the transmission of power – in situations where traditional copper wire might prove unsafe or impractical, for instance. That’s why researchers at Sandia National Laboratories are developing a power-over-fiber (PoF) communications cable. It carries not only data, but also optical power. Read More

Wormhole Station connects Windows to Mac to Android to iOS

By - January 9, 2012 6 Pictures
The PC and Mac advocates have been debating for years over which is superior, with good arguments on both sides; but a third, often overlooked camp exists: people who use both. If you're in that group, then you know how frustrating it can be to have the perks of both machines, but the downside of few easy options for sharing files or peripherals between the two. That's why tech manufacturer j5create has rolled out the Wormhole Switch and the Wormhole Station, which allow file transfers between PC, Mac, Android, and iOS, as well as keyboard and mouse sharing.
