I’ve written about efforts to allow free wireless connectivity access to what is called “White Spaces”, bits of spectrum allocated to over the air TV, but not used.<\/p>\n
It has been proposed that these spaces be used for unlicensed devices, much in the same way that WiFi works now.<\/p>\n
The difference is that the ranges and penetration of the signals are much greater.<\/p>\n
Well, there are two groups lobbying very hard against this, the broadcasters, who have their channels allocated from this spectrum, and the wireless microphone industry, who use the white spaces illegally<\/span>, and have done so for years<\/span>.<\/p>\n Since the FCC tests showed that there was no problem with interference with TV stations, the prototypes did the necessary, “sense and avoid,” of occupied space, there isn’t a problem there, so my take is that their opposition is because they think that they “own” this space, and they think that there may be a way to monetize the space, so they have enlisted wireless microphone users: (quoting Harold Feld on I gotta admire the broadcasters (as represented by their trade orgs, the National Association of Broadcasters<\/a> (NAB) and the Association for Maximum Service Television<\/a> (MSTV)). Even with the facts completely against them, they never give up trying. Sadly, they all too often succeed through a combination of heavy duty lobbying power (what politician doesn’t suck up to his or her local broadcaster?) and the fact that most decision makers don’t know squat about engineering and regard the whole thing as black magic. Heck, it worked to hamstring low-power FM (LPFM) radio, despite a subsequent independent government report showing the broadcaster interference claims were unsubstantiated bologna<\/a>.<\/p>\n But embracing radio pirates<\/i><\/b> by proposing to expand the availability of wireless microphones in the broadcast white spaces for their political allies and tacitly agreeing to amnesty for illegal wireless microphone users<\/a>? Even I never thought they would go that far. <\/p><\/blockquote>\n He also notes that the US military uses the technology in question for protection of their troops in life threatening situations.<\/span><\/p>\n
