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.
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 | Articles | 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.
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.
After three years of deliberation, the IEEE802.16m air interface definition will be ready for prime time in the next few months. This critical step toward creating true 4G cellular technology based on WiMAX is important enough to earn compliant products a new name: WiMAX 2. Further proof came last month, when an impressive subset of the WiMAX community created the WiMAX 2 Collaboration Initiative to "improve the economics of mobile broadband" and "to create a better value chain for service providers.
Welcome to Brainstorm! How do you assess and manage these constraints while at the same time improving the overall design process and productivity? Jon Friedman, Aerospace & Defense Industry Marketing Manager, The MathWorks As a manufacturer of military electronics, engineers are faced with unique technical and cost/risks design constraints.
Are lithium-ion batteries up to the task and is it realistic to think that in 2 to 3 years a car battery could be recharged in an hour? By Jim Stegen, Auto Systems Architect, Analog Devices, Inc. MIT scientists have developed a battery that can recharge a device in seconds.
LTE will bring changes to base station design, from both the hardware and software perspective, giving operators challenges as they prepare for technology trials. What do you feel is the greatest challenge today in deploying base stations and how can designers address it? By Frank Ditore, ESL/SystemVue Product Manager, Agilent EEsof EDA Multi-format, multi-band radios are quickly reaching maturity in the commercial wireless infrastructure market.
All indications are that LED backlights will be the preferred light source in mobile applications in 2011, representing a significant growth opportunity for OEMs and the entire backlight and panel supply chain. Do you see the role of LEDs in wireless products changing as the technology matures? By Vandana Lokeshwar, Technical Marketing Manager, Newark Attention is now shifting away from achieving raw light output that matches incandescent bulbs, to increasing the number of lumens per electrical watt supplied.
Welcome to Brainstorm! While Wi-Fi technology has proven to be largely successful in providing inexpensive wireless Internet service within close proximity to the Wi-Fi access point, WiMax technology could expand the potential of wireless penetration and connection quality. Ashish Sharma, VP Corporate Communications, Alvarion Wi-Fi technology has proven very successful for short range broadband connectivity for hotspots, residential homes and enterprises all around the globe, providing inexpensive wireless internet service within close proximity to the Wi-Fi access point through the use of license-exempt frequency bands.
Welcome to Brainstorm! The detection of counterfeit components has become increasingly difficult. The majority of parts have the same or similar markings as their qualified counterpart. In many cases, the identification of major manufacturers is applied despite manufacturers' efforts at product differentiation.
Power Optimization Welcome to Brainstorm! To meet the challenge of increased power consumption in today's complex and integrated designs, a variety of techniques are available to be used in combination. What tools and techniques are available today that help designers to find the optimal power solution very early in the design process? By Vandana Lokeshwar, Technical Marketing Manager, Newark Environmentally driven design guidelines covering aspects such as power efficiency and standby consumption are coming into force in US, European and Asian markets, and have a major impact on power design in new products.
Welcome to Brainstorm! The antenna is a key component in an RF system and can have a major impact on performance. What are the most desirable antenna characteristics when used in a MIMO technology-based wireless device? By Monty Rohde, Product Management Director, Laird Technologies, Inc.
EPC-compliant RFID UHF tags deliver accurate, affordable and unique identification. They create real-time visibility for identifying and tracking objects moving through the supply chain or on and off the shelves. But there are many different types of tags and formats to choose from, depending on the application.
When it comes to choosing between FPGAs and ASICs, both technologies have their pros and cons. Ultimately it is the designer's decision as to which one will help get the product to market on time or better yet, before the competition does. Q: In high-volume consumer electronic devices, which is the best technology to use: FPGA Design Flow or ASIC Design Flow? By John Burton, Vice President of Marketing for Octera Solutions The answer of course is 'It depends'.
There are inherent risks when it comes to wireless technology in medical electronic devices – security, performance, coexistence, EMI and privacy. Q: What are the requirements for effectively deploying and managing wireless medical devices? By R. Srinivasan, Principal Software Engineer, Cambridge Consultants Nowhere are the demands on wireless technology more complex and more critical than in the medical device industry.
