Combo Chips Pack A Punch 

Connectivity options such as Wi-Fi, Bluetooth, cellular, and other radio technologies greatly extend a mobile phone’s usefulness. But the need for multiple radios leads to design challenges—more cost, more drain on battery life, more space, and more radio interference. That’s why more manufacturers are looking to combo chipsets for solutions. ...

Security Is A Key Factor In Femto Adoption 

Smart operators can use femtocells to address their indoor coverage issues, but not before they can guarantee the security of their operation....

Whatever Happened to Femtocells? Ask the Operators 

Femtocells burst onto the scene in the U.S. with great fanfare in 2007. Yet two years later, significant consumer adoption seems nowhere in sight, despite trials by AT&T, Sprint, and others. So what happened? What’s really holding back the rollout of femtocell technology and consequential adoption by consumers? The simple answer is the operators....

A New Approach to Mobile Product Design That Reduces Development Time 

November 4, 2009 at 2pm EST
This webinar will tackle the challenges of “cramming” more features into mobile devices. It will shed light on design techniques that enable rapid feature expansion while managing critical power and mechanical design issues....

Net Neutrality Is Negative News 

While application providers like Google and Microsoft push for net neutrality, regulation will hurt consumers and stifle innovation from carriers. ...

Next-Generation Wireless Backhauling Requires Sophisticated Silicon Support 

One of the major challenges that carriers and service providers face is the migration from this heterogeneous, inefficient, and complex infrastructure toward a simple and cost-effective Ethernet-based transport network. One solution, though, can enable this migration to happen in a controlled, flexible, efficient, and smooth way based upon on new technology. ...

W-CDMA Transceivers Require Smart Power-Management Solutions 

Handset designers need to optimize RF transmitter power consumption. The best solution uses a voltage controlled dc-dc converter that dynamically adjusts the RF power amplifier supply voltage to continuously achieve the highest possible power efficiency for each RF power level. This technique is called DVS, or dynamic voltage scaling. ...

Ensure Video Quality in Your Mobile Delivery 

Though mobile devices are becoming more sophisticated, with more processing power and better usability, providing video across multiple platforms remains a challenge. ...

Crystal Oscillators Still Deliver Superior Performance 

Thought to be technology of the past after the onset of silicon oscillators based on MEMS, crystal oscillators have held their own. With the addition of cost-effective, configurable technology, manufacturers can produce crystal oscillators that provide significant business and performance advances across a wide frequency range of 750 kHz to 1.35 GHz.Thought to be technology of the past after the onset of silicon oscillators based on MEMS, crystal oscillators have held their own.

Apply Load-Pull Analysis To Wireless Device Characterization 

Tektronix, Cardiff University, and Mesuro Limited are developing active harmonic load and source pull measurement systems for nonlinear device characterization. The following questions and answers should help explain the technology, which may be unfamiliar to many designers. ...

Location-Based Technology Keeps Getting Better 

The Multiple Range Estimation Location (MREL) system from the Andrews Solutions division of CommScope improves location-based technologies, exploiting features in newer digital signaling protocols to produce location results in areas that U-TDOA cannot. ...

Prepare for the Mobile Broadband Tidal Wave 

As mobile communications grow, the industry will see three major disruptions—the rise of mobile broadband, consumer-friendly billing plans, and multimedia device usability—that will change mobile operator business models. ...

Smart Phones Surge In An Otherwise Weak Market 

While overall handset sales are down for 2009, the smart-phone segment is seeing an increase driven by hot new models from Apple and BlackBerry with plenty of consumer-friendly features and third-party apps....
