Wireless PC Peripherals Point the Way for RF Remote Control

July 8, 2010 1:02 pm | by Sveen-Tore Larsen, Nordic Semiconductor | Comments

Consumers are starting to complain about infrared (IR) remote control’s inability to cope with the demands of modern media devices. A recent study by Strategy Analytics1, for instance, found that while early adopters of advanced Internet TV services (such as AppleTV, Hulu, and AT&T U-Verse) value the ability to personalize and share their content, the adoption rate could be slowed because consumers “want better control devices and superior user experience”.

The RF Sting in the Digital Transmission Tail

July 8, 2010 12:38 pm | Comments

Simon Whittle, Nujira Ltd. The new generation of data-oriented digital communications networks being rolled out in the cellular, broadcast, military and other environments carries a sting in the tail for RF designers. In order to achieve high data rates, these new standards use advanced modulation techniques such as OFDM which significantly increase the variations in amplitude of the transmitted signal.

LTE vs. WiMAX – A Test Perspective

June 29, 2010 4:43 pm | Comments

By Graham Celine, Azimuth Systems The marketing battle between WiMAX and LTE is raging in an effort to declare which is the best solution, and vendors and service providers are racing to put stakes in the ground to claim the first or most predominant network delivering wireline speeds. However, the true challenge still lurks in the background and has yet to raise its head: which technology will work better, which will provide more throughput, which will offer better range and which will deliver more flexible mobility? The ability to put each of these technologies through their paces and comprehensively test and benchmark the performance of the network is pivotal to the success of either technology’s rollout.

WiMAX and the Effects of Multipath

June 14, 2010 1:05 pm | Comments

By Ray Chadwick, Berkeley Varitronics Systems, Inc. WiMAX signals suffer from the effects of multipath and exhibit broadband fading characteristics that are very apparent in the spectrum of the received WiMAX signal (see Figure 1). It’s not a trick; OFDM modulation does not eliminate fading and is not always received with a flat spectrum.
