This is part two of a three part series. Read part one By Dr. Michael D. Foegelle, ETS-Lindgren; Kevin Li, Nokia Corp.; Andrew Pavacic, Paul Moller, Motorola, Inc. Defining the Grip An informal survey of advertised handsets on the market revealed that they could generally be separated into two categories by width.
A new modeling methodology combines FPGAs and detailed circuit-level modeling in a design-to-test flow. By Greg Jue and David Leiss, Agilent Technologies click to enlarge Figure 1. This high-level design flow begins with the design of key algorithms which can be quickly evaluated in simulation to verify system performance with just a handful of simulation blocks.
Emulating the way that the human hearing system characterizes and groups the audio stream into sound sources proves to be an extremely efficient and accurate way to suppress both stationary and non-stationary noise. By Lloyd Watts, Founder and CTO, Audience click to enlarge Figure 1a.
By Nancy Maas, Editor-In-Chief email@example.com Did you know that compulsive e-mailing and text messaging could soon become classified as an official brain disease? An editorial in the American Journal of Psychiatry a few months back said that Internet addiction - including excessive gaming and e-mail/text messaging - is a common compulsive-impulsive disorder that should be added to psychiatry's official guidebook of mental disorders.
By Angela Hribar, Chief Sales and Marketing Officer GlobalSpec, Inc. A key measure of success for OEMs is their ability to get new products to market quickly. Early on, wireless manufacturers must find and source the right components and parts during product design and manufacturing stages to meet demanding deadlines.
A standardized hand phantom used together with the SAM head phantom for radiated performance testing mirrors real-world use. Dr. Michael D. Foegelle, ETS-Lindgren, Kevin Li, Nokia Corp., Andrew Pavacic and Paul Moller, Motorola, Inc. Figure 1. The resulting kinematic CAD model.
By Nancy Maas, Editor-in-Chieffirstname.lastname@example.org M2M can be described as a three letter abbreviation with multiple meanings. To some, it can mean “mobile to mobile” or “mobile to machine.” For the purposes of this discussion, it means “machine-to-machine”, and relates to the remote monitoring and control of machines.
As wireless standards continue to evolve, software-defined ?test systems will continue to evolve with them. By Luke Schreier, National Instruments As the proliferation of wireless standards continues, the idea of using software-defined measurement capability has become a necessity as opposed to a matter of click to enlarge Figure 1.
Testing LTE Design simulation can be useful in addressing LTE design and verification challenges but requires consideration in selecting the appropriate model abstraction for the given phase of the design cycle. By Greg Jue, Agilent Technologies Emerging standards such as 3GPP Long Term Evolution (LTE) present a number of design and verification challenges for system engineers.
Nancy Maas Editor-in-Chief Social Networking, Mobile Social Networking, MySpace, Facebook, Friendster, Couch Surfing (I love that one) — what exactly are these things and why are they now such a significant part of people’s lives, particularly teenagers? I had to get a “crash course” recently from my sixteen year old niece to find out.
Thorough and accurate Multimedia Messaging Service (MMS) testing is critical to the successful deployment of any mobile phone offering a MMS capability. By Scott Grimmett, Agilent Technologies Over the years, the mobile-phone usage model has changed quite dramatically. No longer is it used solely for its voice services.
For a US company intending to launch a worldwide product, compliance with EuP regulations will ensure entry to that market of almost 500 million people. Jeff Uden, Newark One of the most interesting trends in the electronics industry at the moment is the movement towards designing products in an environmentally friendly way.
As the variety of user devices and applications increase, the need to predict end-user experience becomes even more critical. Sudeep Gupta, Azimuth Systems Wireless access communications have changed dramatically over the past five years. As users demand more from their mobile devices, the interaction between the devices and the radio environment has become more complex.
Multicore processors are now an increasingly common and effective tool to address the challenges of power and ?performance in cellular basestations. Although wireless’ killer application is still voice, data is rapidly becoming a close second for 3G, a trend that will continue as operators deploy 4G technologies such as mobile WiMAX (IEEE 802.16e) and Long Term Evolution (LTE).
By Gary Nevison, Newark Designers of electronic and electrical equipment are increasingly challenged to design new products that comply with legislation that applies in the markets where their products will be sold. As more US manufacturers sell their products internationally, design engineers not only need to consider legislation in the U.
