This is the second article in a three-part series. The first article examined the driving forces for QoS in mobile networks. This article outlines the technical requirements of the LTE QoS framework, including the critical parameters and policy controls, and how these fit into the LTE architecture.
Retinal (or fundus) photography is an essential part of any ophthalmology practice. Commercial fundus cameras can cost tens to hundreds of thousands of dollars, making the technology out of reach for smaller ophthalmic practices and to physicians in third-world countries.
NASA's Mars rover Curiosity has resumed a trek of many months toward its mountain-slope destination, Mount Sharp. The rover used instruments on its arm last week to inspect rocks at its first waypoint along the route inside Gale Crater. The location, originally chosen on the basis of images taken from NASA's Mars Reconnaissance Orbiter, paid off with investigation of targets that bear evidence of ancient wet environments.
Ongoing worldwide adoption of mobile devices has created unprecedented demand for access to e-commerce, social media and entertainment applications anywhere, at any time. This has not only increased the amount of mobile broadband traffic transported by the carrier networks, but also transformed its composition.
About 60,000 people have come from all over the world to attend Oracle's biggest customer conference of the year, but Oracle CEO Larry Ellison left no doubt Tuesday that his boating team's defense of the America's Cup is a higher priority. Ellison, a billionaire renowned for his flamboyance and hubris, delivered that message by snubbing the crowd that had gathered at a San Francisco convention center to see him on stage.
Vishay Precision Group, Inc. has announced that its Vishay Foil Resistors brand (VFR) has released a new video that demonstrates the shunt calibration of strain gages using Bulk Metal Foil resistors. Providing long-term accuracy and stability regardless of the operating environment, foil resistors provide a cost-effective and convenient alternative to using certified weight standards for calibration.
Ottawa, Canada-based TrueNorth Avionics outfits private, VIP business jets with airborne telecommunications technologies. With full telecommunications capabilities available, passengers can turn otherwise nonproductive time in the air into useful working time, or — in the midst of a hectic and grueling travel schedule — grab a few moments to stay in touch with family and loved ones at home.
Broad Offering of Innovative High-Power Semiconductors and Discrete Semiconductor Products Now Available World-Wide
Apple says shoppers snapped up 9 million of its newest iPhones since the devices were launched Friday, and that demand is exceeding supply. The two new models gave Apple it its strongest iPhone launch ever, and many online orders are scheduled to be shipped in the coming weeks.
The fingerprint-based security system used to unlock Apple's latest iPhone can be bypassed using a household printer and some wood glue, a German hacking group has claimed. A spokesman for the Chaos Computer Club said the group managed to fool the biometric sensor in the iPhone 5S over the weekend by creating an artificial copy of a genuine fingerprint.
With the rise of the iPhone, Android, and other mobile devices has come a flood of applications designed to help people stay healthy. Food and Drug Administration officials say they will begin regulating a new wave of applications and gadgets that work with smartphones to take medical readings and help users monitor their health.
A lot of energy is wasted when machines turn hot, unnecessarily heating up their environment. Some of this thermal energy could be harvested using thermoelectric materials; they create electric current when they are used to bridge hot and cold objects. At the Vienna University of Technology (TU Vienna), a new and considerably more efficient class of thermoelectric materials can now be produced.
While searching for ever smaller devices that can be used as data storage systems and novel sensors, physicists at Johannes Gutenberg University Mainz (JGU) have directly observed magnetization dynamics processes in magnetic nanowires and thus paved the way for further research in the field of nanomagnetism.
Today on Meaghan's Minute, brought to you by Memory Protection Devices, Microsoft's new Surface Pro 2 tablet has a built-in kickstand, and can be used flat on a table, or in someone's lap. It also has a 75 percent improvement in battery life.
Pacemakers, insulin pumps, defibrillators, and other implantable medical devices often have wireless capabilities that allow emergency workers to monitor patients. But these devices have a potential downside: They can be hacked. Researchers at Rice University have come up with a secure way to dramatically cut the risk that an implanted medical device could be altered remotely without authorization.
Researchers from UCLA's Henry Samueli School of Engineering and Applied Science have developed a transparent, elastic organic light-emitting device, or OLED, that could one day make all these possible. The OLED can be repeatedly stretched, folded and twisted at room temperature while still remaining lit and retaining its original shape.
A former senior executive at Qualcomm made nearly $250,000 in illegal profits from using inside information to buy stock in the wireless technology company and an acquisition target before major public announcements, according to an indictment unsealed Monday.
BlackBerry's largest shareholder has reached a tentative agreement to pay $4.7 billion for the troubled smartphone maker, even as many investors fret about its potential demise. BlackBerry said Monday that Fairfax Financial Holdings has signed a letter of intent that "contemplates" buying the company for $9 per share in cash in a deal that would take the company private.
Chip-making equipment manufacturer Applied Materials is acquiring Tokyo Electron, a rival maker of equipment for production of semiconductors, flat panel displays, and solar panels. The two companies said Tuesday their $9.39 billion all-stock transaction will result in the creation of a new company with a market capitalization of about $29 billion.
Leader Tech has announced the publication of its first, full-line EA Microwave Absorber catalog. This technical guide features a large selection of narrow and broad band materials for attenuation of frequencies ranging from 500 MHz to greater than 40 GHz.
On Friday, Senator Al Franken asked Apple for more clarity on privacy and security concerns he has with its use of fingerprint recognition technology in the new iPhone 5S. Franken said that the fingerprint system could be potentially disastrous for users if someone does eventually hack it.
Ericsson and Orange are expanding their business together in Switzerland. As part of the new agreement Ericsson will supply core components of the new hardware and software architecture supporting Orange Switzerland’s business processes, or business support systems (BSS).
This week on WDD’s HotSpot, brought to you by National Instruments, a low voltage, miniature TCXO; a satellite with the mission to clean up space; EnerSys Buys Purcell Systems for $115M; and resistive switching devices.
The roving laboratory performed extensive tests to search for traces of Martian methane. Whether the Martian atmosphere contains traces of the gas has been a question of high interest for years because methane could be a potential sign of life, although it also can be produced without biology.
MTGx and RocketSpace welcomes you to the first ever Google Glass Hackathon event. It brings together over 40 developer teams to present product ideas and solutions which explore the groundbreaking potential of Google Glass as an entertainment accessory and second screen device.
