Re: Here's the problem said by fifty nine:In other "free" bands such as 2.4GHz and 900MHz it is literally filthy as a sewer with spectrum pollution. The difference between those spaces and white space devices is that white space devices broadcast on actual TV channels, versus 900MHz and 2.4GHz where there isn't much of anything important. which channels? specifically which MHz range is this supposedly going to affect? Do you even know? |

Do you even know? Sure I do. And I know exactly how to render these devices ineffective.
Furthermore, a signal of -114dbm while usable for me with a high gain antenna (which would bring it up above -114dbm) would basically give the green light to a white space device to fire up and pollute away.
I'm sure just like cell phone jammers someone will just make a WSD jammer (it's not that hard) to emit a signal just long enough to render WSD devices in the area ineffective.
This is yet another reason to say NO to WSD's, because they can be shut off very easily.
Finally, testing of these devices was conducted in a very slipshod manner with the FCC again just relying on a half assed test to make a decision. Not surprising when the agency is packed with lawyers and lobbyists who have no clue about RF in the real world. |

So then using your logic cell phones should be banned. So people won't use cell phone jammers. |

Probably nearly all of them around here, since at the ground level they are below -114dBm since they are blocked by trees and hills. Well except the religious and Korean broadcasters that are close by.

Cell phone jammers are already illegal but tons of people use them because they are fed up the cell phone nuisance.
I predict that WSD jammers would be used in much the same manner. In fact all I'd need is really a TV transmitter which isn't that hard to get. |
