System-Level Design and Verification of Wireless Embedded System to Meet Global Demands Using a Mixed Domain OscilloscopeJanuary 10, 2013 3:16 pm | by Faride Akretch, Technical Marketing Manager, Tektronix | Comments
Designing and implementing wireless systems so they can be used in different geographic regions around the world represents a significant challenge. Wouldn’t it be nice if everyone all agreed on the use of frequency, modulation type, power levels, and bandwidth?
What are some key considerations when selecting a high frequency circuit board material? Art Aguayo, Sr. Market Development Manager, Rogers Corporation Determine the dielectric constant needed and the dielectric loss desired. There are many factors around these properties that are rarely captured in a data sheet or software property table, yet are very important in the selection of high frequency materials.
Wireless sensors are applicable for a variety of applications, whether it be smart cities (smart parking, smart lighting, waste management), industrial control (M2M applications, indoor air quality, temperature monitoring), eHealth (fall detection, patient surveillance, ultraviolet radiation) and many more.
Energy harvesting wireless technology monitors and controls large-scale industrial plant facilities By Jim O’Callaghan, President of EnOcean Inc. Essential factors for the success of a business include production up-time and process machinery efficiency. Real-time monitoring of machinery makes it possible to detect and prevent equipment failure proactively.
In wireless systems, interference in the wireless channel can be quite problematic, degrading the reception of desired signals. It can originate from a variety of intentional, unintentional and incidental radiators and occurs in both licensed and unlicensed spectrum. With the growing scarcity of radio frequency spectrum and ongoing efforts to improve its utilization for the highest capacity and performance (e.
Brainstorm : How does the future of the wireless industry affect M2M communications? Dr. Erez Manhaimer, VP of Marketing, Alvarion As the demand for M2M communication grows, the wireless industry provides a common, mature IP infrastructure that can be deployed cost effectively making it an enabler of M2M communications.
Brainstorm : With the advent of wireless equipment designs being challenged for high reliability demands, what connectivity considerations must be taken? Today’s process infrastructure requires practices and equipment that keep operations functioning regardless of environmental conditions or other potentially harmful disturbances.
Where in the design cycle is it best to spec in a timing device, and why? Ramon Cerda, Vice President of Engineering , Crystek Corporation The short answer is; as soon as possible. Most, if not all timing devices should be treated as long lead-times items. If the crystal oscillator manufacturer does not have your particular frequency and/or specification requirement in stock, it can take many weeks before they can deliver the timing device.
It’s not uncommon to look at a discrete component’s datasheet and think that the manufacturer might be willing and able to tweak the performance for you in exchange for a little NRE and an up charge on the standard price. But a MMIC is another story. Or is it? Like so many things, advanced government and space programs have been influencing the MMIC market for years.
Introduction Most modern audio is stored in digital formats such as pulse code modulation (PCM), and MP3s. This provides lossless data storage, perfect copies without quality degradation, indefinite storage, flexibility, and compatibility with other digital systems. An audio DAC converts these digital formats into analog signals that drive speakers which create audio sounds or analog waves.
How are you responding to the demand for low power/high efficiency devices in the emerging markets? Jeff Schnabel, VP of Marketing at CUI Inc : In order to address the growing global concerns regarding energy consumption in electronic equipment, the power supply industry has largely focused on improving the operating efficiency of ac-dc power supplies and dc-dc converters.
Simulation-based assessments are fast, cost-effective, and ensure success. Introduction Successful integration of an antenna onto a vehicle platform poses many challenges. Vehicle features impact antenna performance by blocking, reflecting or reradiating energy, and co-site interference can impair the effectiveness of multi-antenna configurations.
In the future, how will battery technology need to respond to the increased power demands of today’s advanced sensors? Technological advancements are creating a dynamic growth curve for sensors intended for use in remote areas where there is no connection to the power grid.
At the recent Consumer Electronics Show (CES), a major trend in many of the whizzy new gadgets that were on display was the enhanced interactivity and environmental sensing capabilities of products, from smart phones to games to the burgeoning tablet market. Whether it’s rotating a display from portrait to landscape mode; determining location, direction and elevation, or even improving the wireless transmission quality and battery life, there is a common thread connecting this new wave of innovation in devices: MEMS, or Micro-Electro-Mechanical Systems.
This year was an important one for WDD, with new roles and new people in our staff, changes in our editorial, and disruption in the marketplace. As we enter the New Year we look at it with great promise for both us as a publication and you as our audience. We will not only continue to serve you and our industry, we will do it in interesting and informative ways to keep you on top of wireless technology and the devices involved.
