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”.

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.
