The Question: "The constant movement of data increases a company’s exposure to the risk of data loss. What type of solutions can help cost effectively identify and protect an organization’s critical data from internal and external threats?" By Will Aguilar, Director, Product Management for Wireless, Enterasys Networks The growth of mobile devices in the enterprise has been explosive and drives end-users’ expectation they will be able to access business services anywhere, anytime in the office, campus, or remotely.
This case study will describe an application of the Azimuth Systems Field-to-Lab (FTL) Solution by a market-leading handset manufacturer. Real-world drive testing is very expensive; lab testing is much less expensive and faster -- provided that the real world can be emulated with sufficient fidelity.
People love their smartphones. The convenience of having access to the Internet anywhere and at any time is extremely compelling. In an effort to stoke the fires of demand, the industry is actively improving the offerings. For example, new smartphones now have stunningly high resolution screens to make it more compelling for people to watch videos – and consume mobile data.
By Ashraf Elghamrawi, Analog Devices ( www.analog.com ) The amplifier is one of the most versatile building blocks used in RF/IF signal chains today. They are commonly used throughout designs to overcome signal losses incurred from passive mixers, filters, baluns, and other passive elements. Since these losses occur across the entire signal chain five main families of amplifiers have been developed by Analog Devices.
Beamforming is a signal processing technique that utilizes an array of sensors to achieve directionality, increase the strength of transmitted signals and improve the quality of received signals. Beamforming is extensively used in communications, radar, direction finding, countermeasures, weapons systems, oil and mineral exploration, and medical imaging and treatment.
Problem Solvers - Filters By Jidong Dai, Ph.D., Mike Ferguson, Frank Perkins RFM, and Bob Dockemeyer, Delphi Sirius Satellite Radio broadcasting utilizes highly elliptical orbit (HEO) satellites, resulting in superior coverage over North America where the service is targeted. However, even with superior coverage, there are still areas where the satellite signals are blocked, like city centers with many skyscrapers, overpasses, and areas with strong interference signals.
Welcome to Tech Exchange on Test & Measurement! Each month this new section will focus on a different product category and will include a brief interview with a representative from a leading OEM. This Month: Vivek Vadakkuppattu, Product Manager for Azimuth Systems Q: What were some of the most significant technological developments in the Test & Measurement industry in 2010? At Azimuth Systems, we continued to see the trend of greater focus being put on real world-centric performance testing in 2010.
By Kevin Walsh, Skyworks Solutions, Inc. This article will elaborate on two key trends that are facilitating the growth of embedded WLAN communications in smart phones and other mobile connected devices: 1. The development of pHEMT wafer level chip scale packaging (wlCSP), alternatively known as flip chip or bumped die.
By Roland Gamper, LeCroy Corporation Regardless of the system topology and application domain, the development, maintenance and monitoring of electronic system architectures using mixed protocols requires tools able to straddle several busses, at various speeds and with different line characteristics.
By Sol Jacobs, Tadiran Batteries Rapidly evolving technology and wireless communications have unlocked the dynamic growth potential of remote wireless sensors, resulting in growing demand for hybrid lithium batteries that combine exceptional long life with the ability to handle high current pulses.
Case Study: Customized Coin Cell Holders for Automotive Toll Tags Challenge A leading manufacturer of toll tags recently approached MPD looking for a new battery holder to replace soldered-in batteries. The customer had two main problems with their current battery solution.
By Steve Graves, McObject Among wireless systems developers, database management system (DBMS) replication is typically associated with high availability (HA). Deploying real-time DBMS software on a master node, with multiple synchronized copies of that database running on standby nodes, and automatic failover to one of these replicas in the event of the master node’s failure, provides for instant recovery and maximum system up-time.
By Dr. Oleksandr Gorbachov, CTO, RFaxis, Inc. With over 600 million new mobile phone handsets shipped each year, mobile phones have become an integral part of our daily lives. As more and more new features are being demanded in smaller and thinner handset form factors, excessive current consumption and poor battery life become real issues for the mobile phone user.
By Angus Robinson, Anritsu Company By eliminating wires and simplifying connections between devices, Bluetooth wireless technology influences people’s lives in many ways. Mobile phones, PCs, motor vehicles and portable music players now have the ability to be connected quickly and easily whenever we want.
By Eamon Nash and Ashraf Elghamrawi, RF Group, Analog Devices, Inc. Improving the Power Added Efficiency (PAE) of High Powered Amplifiers continues to be a challenging goal in a Wireless equipment industry that is struggling to deliver cheaper, smaller equipment that consumes either less electricity or in the case of portable devices, less battery current.
