MEMS Microphones Enhance Audio System Quality And Reliability
MEMS microphones solve the power, cost, and complexity issues that typical electret condenser microphones present in most audio subsystems in today’s consumer and communications devices....
In An Evolving Market, Femtocell Manufacturers Need To Stay Flexible
In the fast-moving wireless market, femtocell makers need to develop new products to stay competitive. Yet developing new ICs for new standards or frequencies could take typically two to three years, from conception to volume production. Programmable silicon designed specifically for femtocells may fill the gap....
New Solutions Put Wireless To The Test
With wireless technology finding its way into all sorts of devices and commercial applications, test engineers are increasingly demanding complete RF test solutions oriented around particular chipset vendors. Test equipment vendors have been quick to react to this demand by collaborating with manufacturing test engineers and silicon vendors to make it easier and quicker for test engineers to design and test wireless devices and products. ...
Herd Your Widgets To Bring The Cool Factor To The Masses
While one widget is good and two widgets are better, a phone full of widgets represents a serious design challenge for software developers, handset manufacturers, and mobile carriers alike. With more and more widgets demanding access to the same limited pool of handset resources, something always has to give. ...
IEEE SECON 2009 Set To Open In Rome
The Sixth Annual IEEE Conference on Sensor, Mesh and Ad Hoc Communications and Networks (SECON) will be held June 22-26 at the Centro Congressi Cavour in Rome, Italy. ...
LTE And Femtocells—An Essential Symbiosis
The cellular communications industry is currently abuzz with two big issues: the development of Long-Term Evolution (LTE) and the emergence of femtocells. Although the two may at first sight appear barely related, it is becoming increasingly clear that they are, in fact, inextricably linked....
New Book Targets IEEE’s Wireless Certification Program
The Communications Society of the Institute of Electrical and Electronic Engineers (IEEE) has announced the availability of A Guide to the Wireless Engineering Body of Knowledge (WEBOK). This 272-page softcover book, published by John Wiley and Sons, was developed as an educational resource for the IEEE’s Wireless Communications Engineering Technologies (WCET) Certification Program. ...
A Dozen New Functions Every Cell Phone Should Have
The cell phone is becoming the universal wireless device (UWD). It offers an amazing number of features now—voice, texting, Internet access, Wi-Fi, Bluetooth, a camera, GPS, MP3 audio, and FM radio. But the possibilities are even greater. There are so many more features it could provide to help it achieve that “universal” status. What’s it missing? Here are some suggestions. ...
LTE—the Carrier Ethernet Way
Long-Term Evolution (LTE) is generating quite the buzz these days—and with good reason. LTE can carry more voice, video, and data traffic than ever before. The key is to stay ahead of the curve by transitioning legacy networks to Carrier Ethernet-based transport networks to keep up with the growing demand for bandwidth....
Crystal-Oscillator PSR Improves 802.11n EVM Performance
Power-supply rejection (PSR) performance significantly impacts the error vector magnitude (EVM) performance of 802.11n systems....
High-Speed Bluetooth Uses 802.11 To Hit 24 Mbits/s
The BT SIG has announced a faster version of the widely used Bluetooth PAN standard called Bluetooth Core Specification Version 3.0+ HS. ...
Data Service Demands Shift Mobile Operator Focus To Wireless Repeaters
Even with the current economic climate, wireless operators continue to invest in their infrastructure. While the timing of upgrades to 4G technologies are the subject of debate, the demand for data services is driving coverage fill-in for existing 3G networks. To meet these demands, operators are rapidly deploying wireless repeater technologies....
