Brainstorm: Time Device Technologies

June 13, 2013 12:18 pm | by WDD Staff | Comments

Any device or system that requires a clock or timing device to function will improve its performance as the quality of the timing device improves. Parameters that define the quality of a timing device include: phase noise, jitter, temperature stability, aging, PSRR, power dissipation, G-sensitivity, as well as other parameters that are sensitive to a particular application.

Protection against the Elements

June 11, 2013 3:23 pm | by Meaghan Ziemba, Editor, WDD | Comments

Demand for wireless communications has created an increase in telecommunications equipment, as well as a need for advanced, high-quality infrastructure to help prevent product failure, especially in hash environments. Outdoor telecommunication devices experience severe weather and daily temperature fluctuations, causing strong pressure differentials inside the equipment, which can stress and damage housing seals, allowing leaks to occur.

Resolve Signal Integrity Issues in Cloud Computing Platforms

May 30, 2013 8:48 am | by Bill Weir, Pericom, www.pericom.com | Comments

While the cloud promises to reduce enterprise network infrastructure and operating costs, the remote execution of applications makes factors such as latency, performance, and reliability critical considerations in the design and deployment of cloud computing platforms. A key factor determining server performance, cloud or not, is maintaining a bit error rate (BER) on the order of 1.E-12 for the overall system.

System-Level Design and Verification of Wireless Embedded System to Meet Global Demands Using a Mixed Domain Oscilloscope

May 28, 2013 3:15 pm | by Faride Akretch, Technical Marketing Manager, Tektronix | Comments

Designing and implementing wireless systems to 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? Unfortunately, that’s not the world we live in and radio regulations vary from region to region, especially for some of the frequencies used in unlicensed radio...

The Drones of Oil

May 17, 2013 9:09 am | by Kim Andreassen, Centre for integrated petroleum research, University of Bergen (UiB), Uni Research | Comments

Geologists have long used seismology on the bottom of the ocean or have been throwing dynamite from snowmobiles when they look for oil. But now researchers at Centre for integrated petroleum research (CIPR), a joint venture between the University of Bergen (UiB) and Uni Research, have found a new preferred method – using drones to map new oil reserves from the air.
