In February of 2009, analog television will cease to broadcast. Satellite and cable subscribers shouldn't see much if any change in the way things work. If you're like me and just use rabbit ears, however, you're either going to have to resort solely to videos or purchase a converter. Most of the attention is usually focused on the fact that people will have to get converters. I want to draw your attention to another aspect of the change.
When broadcasting of analog television stops, a segment of the electromagnetic spectrum will be freed up for other uses. The FCC is auctioning off this frequency space around 700 MHz to companies (I suppose an individual could purchase one, but the prices involved are in the high hundreds of millions to billions of dollars). This opens up the opportunity for all manner of new devices for consumers to purchase. New cell phones with better ranges (think of all the places you can get TV signal), wireless Internet, et. al.
As a sound engineer for live systems, I must admit myself concerned. Wireless microphones don't really have any frequency dedicated to them. Instead, wireless microphone transmitters operate in the space that TV channels aren't using. For example, from my antenna I can get channels 8, 10, and 12 but no 9 or 11. Wireless mics would operate in portions of those gaps such as 9, or 11. But after the FCC sells licenses to these frequencies to companies, those companies might put some sort of system in place that uses the frequencies, which would mean that wireless microphones wouldn't be able to use them. Luckily for me, many companies are expected to purchase blocks of frequency and leave those frequencies unused in order to protect their cell phone lines. If a new company was allowed to buy a frequency block and build a competing service, the large cell service providers would lose a lot.
So I am concerned, but I am also hopeful. And on the bright side, I don't have to worry about it for another year.
