The audio industry is filled to the brim with magical devices that are capable of reshaping the reality of those that dare tread within its realm. There is often utter bewilderment at the expressions some people use to converse with each other on the subject. What is the color of sound, 'clarity', 'warmth', 'coarseness'? These are also the same people that will take out a mortgage to buy a sound system, and even spend $10,000 on a single cable - yes, we're back to this chestnut again. (Update, 3/30/15: Pricing has been falling dramatically for these cables since the time the original article was... Read more...
A couple of hours before folks on the east coast could see this past Wednesday's sunrise, some found themselves battling to get webpages to load, or found themselves without Internet entirely. It'd be understandable in this situation to jump to the assumption that a DDoS has taken place, since it's become (far too) common lately, but this partial outage had nothing to do with that. Instead, it hinged entirely on aging networking equipment. BGP is a virtually unknown acronym to the end user - even those who might know a little bit about general networking - but it's integral to making the Internet... Read more...
At a time when many are still in awe of the speeds that can be reached with Google's Fiber service, Danish researchers have come along to show us what those fiber wires can really do. The "High-Speed Optical Communications" team at DTU Fotonik in Lyngby, Denmark, have managed to secure a world record by achieving a transfer speed of 43Tbps across fiber using just a single laser. This achievement far exceeds the previous world record, of 32Tbps. Making this world record possible is a brand-new fiber cable; unlike regular fiber which contains a single thread, or core, this new fiber contains... Read more...
Thanks to the efforts of some MIT researchers, our use of the Transmission Control Protocol could soon experience a nice upgrade. Since its introduction decades ago, TCP has become an integral part of our networking, whether we're connecting to another PC in the same building, or out to a remote server to fetch a webpage. In fact, because of its importance, TCP is one of the most-used pieces of software in the world. A lot has changed since TCP's introduction in the mid-70s, however. We're constantly changing what sort of data we're pushing across our network wire, and as such, there's never been... Read more...
When Google first unveiled its 1Gbit fiber Internet service last summer, it seemed unlikely that such speeds would become common anytime soon. However, there was great hope that with Google's pressure, other ISPs would be pushed towards offering their own 1Gbit services. This past April, we did see some evidence of that, with AT&T promising to roll out its own 1Gbit service in the Austin, Texas area. Things don't stop there. It seems that some of the biggest ISPs are being seriously slow to catch onto the 1Gbit option, with Verizon charging a staggering $210 in some areas for a 300Mbit/s connection.... Read more...
At a time when some of us are finding our home Gigabit lines a bit constrictive comes some Germans from the Karlsruhe Institute of Technology to help make our setups feel even more inadequate. The folks there have created a Wi-Fi solution that uses "better hardware" along with a high radio frequency of 240GHz to produce a constant connection speed of 40Gbit/s (5GB/s) at a distance of about 0.6 miles (much further than the 20 or 30 feet inside of your house). The ultra-high 240GHz frequency is required to push such heavy data, which at 40Gbit/s is about 293x faster than the theoretical maximum... Read more...
We posted a rumor over the weekend that Google's high-speed Fiber Internet service should be hitting up Austin soon, and today, the company confirms it. The announcement was made in the city today, along with mayor Lee Leffingwell, and Google's decision to choose Austin to follow-up to the dual Kansas City's can be summed up in one sentence: "[Austin is] a mecca for creativity and entrepreneurialism, with thriving artistic and tech communities, as well as the University of Texas and its new medical research hospital." While that's all fine and good, there's little doubt that the jealousy of... Read more...
Only a few months after Google brought Gigabit broadband to Kansas City, Google is rumored to be gearing up for its next metropolis: Austin, Texas. Google is planning a big press conference in Austin next week. The word is that Austin and Google have an announcement to make. Google and Austin officials haven’t admitted to anything yet, but with rumors flying and a Tuesday conference planned, it’s worth taking note of. So, why all the commotion about Gigabit broadband? Speed, of course. With Gigabit broadband, you’re looking at being able to watch streaming video at higher resolutions... Read more...
The sultan of search (Google, who else?) wants the Institute of Electronics Inc. (IEEE) to implement a variable-speed Ethernet standard that would make it more efficient to transfer data between data centers and ultimately cut costs. It's a move IEEE has so far been reluctant to take on. Ron Johnson, a director of product management at Cisco, originally proposed the idea at Light Reading's Ethernet Expo and was disappointed that IEEE chose to stick with the usual single-rate format when it came to 400Gbps. Now it's Bikash Koley, Google's principal architect and manager of network architecture making... Read more...
Many have chided Apple for the lack of ports available on its high-end laptops. If you want, you can spec out a $3k+ MacBook Pro laptop... but you can't get more than two USB ports on it, no matter what sum you're ready to shell out. For hardcore power users, the limitations can become something of an annoyance, but that's where third-party accessory makers step in to fill the void. Kanex has already supplanted the outgoing AirPort Express design with the mySpot, and now the company has introduced a genius new adapter that makes up for the MBP's dearth of connectors. The new DualRole is a USB 3.0... Read more...
Despite the fact that 802.11ac products have barely even penetrated the market up to this point, we now have another standard to keep our eyes on: 802.11ad. No, that's not some odd date format talking about the year 802, but rather an upcoming wireless standard that's said to be more revolutionary than evolutionary - the latter of which 802.11ac is. Due in 2014, the 802.11ad standard will open up a new band, 60GHz, which will allow for transmission speeds far greater than the typical home network will offer - up to 7Gbit/s. It's important to note; that's just a theoretical maximum, and... Read more...
With more and more Ultrabook machines pushing Ethernet aside in favor of Wi-Fi, one has to wonder if Ethernet even has a future. But, of course it does! Enterprises and businesses aren't going to ditch the stability of a hard-wired connection in favor of flaky over-the-air alternatives, but with 802.11 taking off on the cordless front, where's the innovation in Ethernet? Here.s IEEE, the world's largest professional organization advancing technology for humanity, today announced formation of the IEEE 802.3 Industry Connections Higher Speed Ethernet Consensus group. Why was such a group formed?... Read more...
Powerline isn't as popular as it once was, but it's still living life as best it can. TRENDnet has just launched a new, smaller adapter that's actually poised to hide out pretty well in your living room. The 200Mbps Powerline AV Adapter with Bonus Plug, model TPL-307E, and the 200Mbps Powerline AV Adapter Kit with Bonus Plug, model TPL-307E2K, which comes with two TPL-307E adapters, are the newest products from the company, able to pipe Ethernet signals via a home's power wiring. It's geared to be more reliable than Wi-Fi, and with 200Mbps speeds, the throughput is certainly higher. The TPL-307E... Read more...
TRENDnet announced a full line of 450Mbps Wireless solutions as well as a 4-Port 500Mbps Powerline AV adapter.
