Unified Communications Market Will More Than Double

Unified Communications Market Will More Than Double

The way in which individuals communicate and collaborate in a business environment has changed dramatically — to the point where all kinds and sizes of companies have arrived at the realization that the flow of information and knowledge throughout an organization needs to be streamlined for competitive reasons. One way to do that is utilizing a unified communications system to integrate conferencing, data collaboration, IP telephony, messaging, mobility, and other functions. So, how big is this market?

Well, in the next five years, the market for unified communications products and services is predicted to more than double expanding from $22.6 billion this year to $48.7 billion in 2012. According to combined market data and research from In-Stat and Wainhouse Research, a 13.7% compound annual growth rate is forecast. See how companies utilize unified communications in a recent survey by Network General Corp.

Amp Delivers Home-Theater Sound

Amp Delivers Home-Theater Sound Without increasing cost, a digital audio amp delivers home-theater sound quality to flat-panel TV speakers by utilizing an audio DSP for speaker tuning, correction, and other improvements. Enhanced audio is the result of processing algorithms that handle HDMI data, analog input, etc., while improving the performance of small speakers and countering playback-quality issues.

MEMS Mikes Hit the Two Million Mark

MEMS Mikes Hit the Two Million Mark There's no doubt that MEMS (microelectromechanical systems) microphones are taking off globally in mobile phones, computers, and other portable digital devices. A case in point: Akustica shipped its two-millionth mike only three months after its one-millionth digital version went out the door. The company attributes part of its success to the ability to manufacture in standard CMOS foundries.

Boosting EMI/RFI Shielding Performance

Boosting EMI/RFI Shielding Performance Improved EMI/RFI (electromagnetic interference/radio frequency interference) shielding performance for electronic devices is now attainable via conductive thermoplastic compounds that allow housings to be lighter in weight and incorporate thinner walls. Key to the development is a filler technology that boosts modulus and shielding characteristics without increasing the stainless-steel-fiber loading. These latest polycarbonate and PC/ABS materials include non-brominated, non-chlorinated flame-retardant versions.

Transforming Smart Materials into Sensors

Transforming Smart Materials into Sensors A highly formable piezoelectric composite functions as a sensor in such applications as noise and vibration cancellation, structural health monitoring — not to mention high-dynamics force sensing. Embedded in a ductile composite polymer, the patch transducers sandwich a thin piezoceramic foil between conductive films. Read more in a brochure that features a tutorial and commercial applications.

Bluetooth Noise Solution

Bluetooth Noise Solution Reducing both noise and echoes sans costly flash memory DSP (digital signal processing), a ROM-based chip not only suppresses background noise on a Bluetooth® headset, but also automatically adjusts volume to the optimal comfort level (no need to push buttons) in noisy surroundings. The net result is clearer conversations at the same cost as a basic headset.

Better Audio through Codecs

Better Audio through Codecs Today's audio codecs are doing more than ever — for instance, digital equalization and dynamics processing — in delivering top sound quality in flat LCD and plasma TVs with limited space for speakers. Similarly, in portable electronic devices, codecs support digital microphones, minimize noise, and deliver long battery life. Examine all the features and specs of these latest audio processors in EE Times.

Wireless Networks Open Up

Wireless Networks Open Up Wireless networks are becoming more open, approaching the Internet model where anyone can access anything using any compatible equipment. In the near future, open wireless networks will be accessed by many more devices and applications. By year end 2008, users will be able to connect to Verizon's network using any compatible device. Meanwhile, Google and handset partners plus carriers like Sprint Nextel and T-Mobile — are working toward open systems.

Push-Button Multimedia Museum Experience

Push-Button Multimedia Museum Experience Sights and sounds for museum visitors take a step forward into a multimedia experience via a handheld device that utilizes a WiFi network and RFID tags attached to displays. Designed to maximize user control, the mi-Guide device lets users navigate via a touch screen and skip the bits they choose. Developed for the Museum of Science and Industry in Manchester, UK, the device could be used in the classroom to bolster lesson-related field trips.

Much Ado about Audio Testing
 

Much Ado about Audio Testing If you're interested in gaining knowledge on audio testing to advance your career, a good place to start is a recent series of articles appearing in Audio DesignLine. Authored by Audio Precision's David Matthew, "Introduction to the Six Basic Audio Measurements" focuses on performance benchmarks or the "big six" measurements. Parts 1 and 2 are already online — stay tuned for the next four installments.

I "See" Said the Blind Boy… via Echolocation

I 'See' Said the Blind Boy... via Echolocation Amazingly, a blind teenager can shoot hoops, skateboard, ride a bike, and even play video games thanks to echolocation skills he self-developed at a young age. Navigating like a bat or a dolphin, Ben Underwood emits a series of audio "clicks" with his tongue. The returning echoes then accurately tell him the location of (and more about) walls, furniture, and other physical objects. What else he can do? Read on.
