One may logically ask, if I am right about the wireless microphones being such a big problem for public safety, why haven’t the public safety folks complained to the FCC about this?
Answer: turns out they have. But, the public safety folks being quiet and unassuming, failed to make themselves heard.
Allow me to change that. The National Public Safety Telecommunications Council, a federation of public safety associations, sent a letter to Chairman Martin asking that the FCC address the problem of wireless microphones back on June 30, 2008. i.e., about two weeks before I filed. While I wish I could claim that it was the NPSTC letter that inspired me, I had no idea it was out there until today. My conversations with the public safety guys were all informal and off the record. Still, as always when folks remind me I’m not an engineer (or an economist, or technologist, or any of the other topics on which I chose to share my humble layperson’s opinion), I am rather pleased to find a bunch of actual engineers that agree with me.
Mind you, the NPSTC letter asks the FCC to go a heck of a lot further than I have. NPSTC wants wireless microphones kicked out of the entire 700 MHz band. I, OTOH, think lots of folks can productively use the broadcast white spaces. Still, I do feel compelled to point out that wireless microphones do not have nearly the level of intelligence/sophistication being discussed for interference avoidance for the white spaces devices at issue in 04-186. Perhaps we should require wireless microphones to rely on sensing as well, or require that they consult an online database for possible new users in the band, or require them to acknowledge some sort of “permissive beacon.” Perhaps public safety entities like NPSTC should administer the database or beacon, and we should require wireless microphone users to pay for these services.
I mean, after all, we wouldn’t want to let these devices run around loose, would we? Think of the terrible interference that might cause. Unless these devices can meet the same rigorous standards that Shure and others seek to impose on unlicensed devices in 04-186, I don’t see how we can ask NPSTC to abide by circumstances that they feel place our public safety at risk.
Stay tuned . . . .
