You are ready and packed to leave on a holiday trip and for the first time, you agreed that your teenage son can stay home alone. The control freak in you is already making long lists of daily and weekly tasks and to-do’s to keep the pets and plants alive, and the calamity predictor in you wants to anticipate for flooded bathrooms and burning fryers.
LTE is no longer the future of telecommunications; it is now a key component of the network’s infrastructure. Service providers are investing heavily in this technology to meet customer demand as consumers continue to purchase smart phones, tablets and other wireless devices at unprecedented rates.
Following its introduction 20 years ago, GSM has established itself as the de facto global standard for mobile telephony. Since this time, wireless communications has continued to develop. Whereas GSM was initially only designed for voice, the GPRS and EDGE extensions have also made it usable for data services.
According to the National Sleep Foundation, more than 18 million American adults have obstructive sleep apnea (OSA). OSA occurs when the back muscles of the throat relax while sleeping, causing the airway to narrow, resulting in snoring. These muscles could also completely block the flow of air to the lungs.
There are really three sides to proper data security. The first step is ensuring that new employee accounts are created with the proper access rights when an employee joins the organization. The second is making sure those access rights remain accurate during the employee’s tenure, and the third is revoking all access rights when the employee leaves.
Our second newscast for Electronic Component News is brought to you by Mouser Electronics, the electronic components distributor with the widest selection of the newest products. In this episode of Engineering Update, we're discussing new research into larger, safer lithium ion batteries.
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.
Engineers are tossing the batteries and making advances to save wasted energy in more effective and realistic ways Today’s technology offers the OEM more cultivated and feasible power options for wireless networks and devices. Also known as “power harvesting” or “energy scavenging”, energy harvesting is when energy originates elsewhere, from an external source.
By Janine E. Mooney, Editor Design changes present new opportunities, and requirements, that allow the RF industry to assume a much greater application reach. Malcolm Gladwell, a British-born Canadian journalist, bestselling author and speaker, once said, “Connectors are people in a community who know large numbers of people and who are in the habit of making introductions.
By Janine E. Mooney, Editor EMI gaskets are a must in order to properly block all interference from reaching your device. A key concern when shielding your design is choosing a gasket. Gaskets are used to seal seams and other gaps that can cause problems in shielding, thus implementing the best fit is imperative.
By Janine E. Mooney, Editor EMI has the ability to interrupt or even destroy the functionality of unprotected electronics. What’s more important than protecting your valuable electronics from potential threats? Not much. Especially with regards to military electronics, which are growing more and more prevalent every day.
By Janine E. Mooney, Editor Inductors are a vital part of most EMI filters, and can be a smart addition to your design. Connectors, enclosures, resistors, capacitors, attenuators, inductors... and how does this all relate to EMI? EMI inductors “ideal inductors” as opposed to “real” inductors; they have inductance but no resistance or capacitance and they do not either dissipate or radiate energy.
The ergonomically designed Wahl C150 On-site Multifunction Calibrator features unique built in “easy connect” terminals, portable and bench top flexibility, and easy to use intuitive embedded software. Fully protected with an external anti-shock rubber boot with IP 54 rating, it features five user-selectable languages,0.005% accuracy over 1 year, NIST traceability, and HART transmitter compatibility.
Turning Off-the-Shelf Components into an Application-Specific, Total Data Acquisition Solution By definition, the off-the-shelf modular instruments (VME, PXI, VXI, CompactPCI, PCI, etc.) used to create automated test and measurement systems are designed to be general purpose, programmable, and flexible enough to handle a variety of input ranges and types, speeds, and functions.
Boonton has launched “Amplifier Test Bench”, a new software package that simplifies test and certification of RF Amplifiers. Amplifier Test Bench supports analysis of pulsed and linear amplifiers; furthermore it measures gain over frequency and gain over input power. The software supports both fast Boonton peak power meters 4540 and 4500B and a variety of standard generators.
Leading provider of wireless base station enhancement products, Communications Components Inc. (CCI), has now launched its PiMPro family of analyzers in EMEA, which enable mobile network operators (MNOs) to remove the adverse affects of Passive Intermodulation (PIM) – a form of interference - from their networks, and prevent it from damaging quality of service (QoS) and customer experience.
New Measurement Solution For Optical Transmitter Compliance Testing Offers the Highest Bandwidth Optical Waveform Analysis and Increased AccuracyJune 29, 2011 11:12 am | Articles | Comments
Agilent Technologies introduced a new measurement solution for optical transmitter compliance testing on the Agilent 86100D digital communications analyzer. The solution offers the industry’s highest bandwidth optical waveform analysis and increased accuracy. The DCA provides a new approach, known as system impulse response correction, or SIRC, which enables multimode optical receivers with bandwidths in excess of 25 GHz and single-mode receivers with near 100-GHz bandwidths.
Frost & Sullivan's Industry Director Jessy Cavazos and Industry Analyst Prathima Bommakanti, along with guest speaker Matthew Friedman, Senior Product Manager for Automated Test at National Instruments, have completed extensive analysis on the electronic test equipment market. The experts will lead a short teleconference about new findings that affect the market, followed by a live question-and-answer session.
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.
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.
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.
