Data Transfer

Thunderbolt 2 will enable 4K video transfer (Image: Shutterstock/JMiks)

Intel has released further details of the next generation of Thunderbolt, the high-speed hardware interface it originally developed with Apple. Thunderbolt 2 doubles data transfer rates to 20 Gb/s which, with the incorporation of DisplayPort 1.2, will allow the transmission of raw 4K video as well as data.  Read More

If you thought 5G wireless was fast at one Gbit/s, how does 40 Gbit/s sound? That's the new wireless data transmission record set by a team of engineers in Germany using integrated solid state mm-wave transceivers. This data transmission rate was demonstrated over a distance of 1 km (0.6 miles) and it is hoped that such links could be used to close gaps between optical networks in rural areas at a fraction of the cost of installing optical fiber.  Read More

A team of researchers working through Australia’s Centre for Ultrahigh Bandwidth Devices for Optical Systems (CUDOS) has developed data encoding technology that increases the efficiency of existing fiber optic cable networks. The researchers claim their invention increases the data capacity of optical networks to the point that all of the world’s internet traffic could be transmitted via a single fiber.  Read More

Corning's Thunderbolt optical cable

Digital systems are notorious for bottlenecks. It’s no good having a blazing, overclocked PC and an internet connection like a firehose if the USB cable between them is like a straw. It’s even worse when the distance between PC and modem is more than a few feet away, so the cable can’t reach. With the aim of eliminating these bottlenecks, Corning Cable Systems LLC is unveiling its Optical Cable by Corning at CES in Las Vegas. These cables replace copper wires with fiber optics to produce cables up to 100 meters (328 ft) long, that are much more durable and achieve speeds of 10 gigabits per second, which is enough to load a full-length HD video in 30 seconds.  Read More

USB 3.0 is set to get a speed boost from 5 Gbps to 10 Gbps (Image: Shutterstock)

The USB 3.0 Promoter Group has used CES 2013 to announce an enhancement to the USB 3.0 (aka SuperSpeed USB) standard that will see the throughput performance of USB 3.0 double from 5 Gbps to 10 Gbps. The speed boost will come courtesy of enhanced USB connectors and cables that are fully backward compatible with existing USB 3.0 and USB 2.0 devices.  Read More

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.  Read More

WiGig, which is backwards compatible with 802.11, will support beamforming

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.  Read More

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

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.  Read More

By using twisted beams of light, researchers have achieved data transmission speeds of up ...

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
