The battle continues between traditional broadcast companies and new wireless actors on the block that aims to use the white-space, air waves released by the DTV transition. Again there is a dispute if new wireless devices are interfering with airwaves or not. Washington Post reports from the scene where the Wireless Innovation Alliance (WIA) claims that NAB is leading a “misinformation campaign” that misleads decision-makers such as FCC. The question is if new wireless gadgets and devices are or will be interfering with TV signals and similar airwaves. WIAs letter to FCC is pointing out that decisions about white-space usage should be based on technical grounds.
NABs VP Wharton, says in a pressrelease that a successful DTV transition is in peril and that the WIA devices failed testings. ” That is not misinformation but an inconvenient truth”, states Wharton.
This battle do not really focus on the transition as such. I don’t really understand how Wharton can link WIA to a failed transition to DTV, if it fails I think it will be because consumers didn’t get proper information and/or the converter boxes would fail. One example is if the supply would glitch.
My experience is that the digital TV broadcasts might be severely interfered in other ways. I know from several cases (in Sweden) where people had interference in the reception because buses, motorbikes and even trains passed not to far from their home. And made the digital picture freeze or become “pixel-ed”. Just as converter boxes will react differently to bad weather or trees full of leaves, they will react in different ways when it comes to other interfering signals in the air. That is not from any new wireless device but from old fashioned “travel gadgets”. I must point out that interference like this is not common, but it happens quite widely when it comes interference because of weather and trees.
Converter boxes differ on how well they are shielded from other external signals or currents. I think this is a much more serious problem from a consumers perspective. Especially when it is the first generation of converter boxes that will flood retailers shelf’s. How well will they work? I believe no one really knows right now, since the converter boxes are in the making in this moment as you read this text. NTIAs requirements for converters doesn’t really cover this topic, I think.
But consumer will care about their brand new promising box.
