The Electronic Frontier Foundation (EFF), a non-profit organization that was founded in 1990, and champions on behalf of consumers regarding any issues affecting digital rights, recently won three critical exemptions to the Digital Millennium Copyright Act (DMCA) anti-circumvention provisions.
Q: Right now there is a limitation on data rate for each user. Can MUMIMO overcome these limitations and if so, how? William J. McFarland, Chief Technology Officer for Atheros Communications The advent of Web-enabled phones has clearly pointed out that wireless carriers need more system capacity to meet the expectations of their users.
It wasn’t all that long ago that Multiple-Input Multiple-Output (MIMO) technology first captured the cellular industry’s attention by promising higher data rates for a single user using two or four streams of data transmitted (and received) with multiple antennas.
Last December, the Bluetooth Special Interest Group (SIG) announced in a statement that it had adopted Bluetooth low energy wireless technology and that the much anticipated ultra-low power (ULP) form of the popular wireless technology, would be the hallmark feature of the Bluetooth Core Specification Version 4.
The first commercial mobile phone in North America with a built-in camera to capture photographs or video was developed in 2002. As mobile phone usage increases and cameras gain ubiquity in mobile phones, demand for such functionality continues to increase, with significantly strong growth in emerging countries.
The wireless base station has evolved from a bulky rack-full of equipment to multiple form factors targeted at different deployment scenarios. Fourth generation technologies like LTE, and end user behavior which are driven by mobile Internet, set specific capacity and coverage requirements that network operators strive to meet within budgetary constraints to enable a profitable business case.
By Chris Desalvo, Agilent Technologies Commercially available RF transmitters in the ever-evolving wireless communications technology give SIGINT and COMINT mission managers a most difficult task. They need to detect traditional push-to-talk signals, wideband digital communications, and always be thinking of future threats.
Wireless systems are now fully mainstream in our lives, not only in the consumer world of cell phones, Wi-Fi enabled laptops and satellite television, but also in the mission and life critical world of aerospace and defense. Recent applications such as ADS-B (Automatic Dependant Surveillance - Broadcast) managed commercial airline flight, software defined radios, and UAVs (unmanned aerial vehicles) bristling with sensors, all depend heavily on the electromagnetic spectrum to interact with the world, demand the highest in reliability, and are driving new and innovative solutions relative to electrical interconnect.
Mukesh Kumar, Texas Instruments The military electronics industry, which includes mission critical products, has always had quality as its ultimate objective. It was a widely held belief that the military’s computers, communications systems and all things electronic had to be a step or two ahead of everyone else’s systems.
Have the rapid technological changes of the past decade negatively or positively impacted the timing solutions market place?July 25, 2010 8:08 am | by Jim Holbrook, General Manager, Networking and Communications Timing at IDT | Comments
One of the most significant technological changes that has occurred in the past decade has been the shift from parallel to serial busses for high-speed system I/O and also for chip-to-chip interconnect. Examples of this trend are: •PCI Express for PCs, servers and increasingly in networking and communications platforms •Serial RapidIO for wireless base stations •Infiniband and Fibre Channel for data centers •VITA 46.
WiMAX and LTE continue to pose many unanswered questions. Q: What common or overlapping technologies do WiMAX and LTE have in common and will they ever converge for certain applications? By Joe Cozzarelli, Senior Director Broadband RF Products and Glenn Eswein, Director of Product Marketing, Broadband RF Business After three years of deliberation, the IEEE802.
At the American Telemedicine Association’s annual meeting recently the results of a national survey were revealed. The survey of health care and information technology professionals, sponsored by Intel, found that a majority of decision makers believe that the emergence of telehealth will have a major role in improving the care for the globally aging population, aka the “baby boomers.
The path to achieving energy efficiency is ridden with obstacles. Q: If we continue to increase the power efficiency of a product, are we approaching the point of diminishing returns? Will it eventually detrimentally impact the cost of the product? Doug Bailey, VP marketing, Power Integrations This is an interesting question.
The earliest embedded systems – industrial automation and scientific instruments communicated with operators using physical actuators: knobs, dials, gauges, indicator lights, etc. Today’s intelligent devices, especially in consumer electronics, feature more sophisticated operator interaction and boast user interfaces (UIs) comparable to desktop applications.
Consumers are starting to complain about infrared (IR) remote control’s inability to cope with the demands of modern media devices. A recent study by Strategy Analytics1, for instance, found that while early adopters of advanced Internet TV services (such as AppleTV, Hulu, and AT&T U-Verse) value the ability to personalize and share their content, the adoption rate could be slowed because consumers “want better control devices and superior user experience”.
