| OET is not independent!
Yesterday the head of the FCC Office of Engineering and Technology Lab seemed to be very nervous during his presentation. Afterwards FCC Commissioners inappropriately and disrespectfully joked about giving out his home phone number. It seems that in recent years the FCC Commissioners can get any result they want from the OET. |

| He was nervous because he lost his place after page 1 of his presentation.
Also, this was one of the most-watched, heavily-scrutinized processes that the FCC has followed in recent years. And after all was said and done (and redone, and watched), the NAB and microphone folks made it clear that the science didn't matter.
The joke was a joke. The disrespect was part of the punchline. Don't take humor seriously.

Canonsburg, PA | I can tell when someone is treated as a subordinate (by more than one of the Commissioners) rather than as a respected independent engineer! |

Washington, DC | I detected nothing but fondness. While I haven't met the engineer, I've met the commissioner. |

| Are you an RF engineer?
The test results do not support any conclusion other than that a device that relies on sensing alone cannot work.
Devices that use geolocation and database access can avoid stepping on incumbent users, but only if they consult the database before turning on; and only if the database is maintained in real time.
Two questions: How would the device know where it is? How would the device access the database without transmitting? |

said by DavePR : The test results do not support any conclusion other than that a device that relies on sensing alone cannot work. Which doesn't conflict with the FCC's order! The FCC didn't accept equipment relying on sensing alone.

Anything that's going to the field will have to be FCC-accepted so it will have to demonstrate that complies with the order.
You do know we're not the only country doing this, right?

| I hope you're right. I'm hearing a rumor that each device will be individually addressable so conceivably they can be turned off if they are causing interference.
I do wireless for TV. I am one of the incumbent users. Worst case for me is that we confiscate electronics at the entrance to the venue. My real fear is for OTA TV. That is my preferred way to watch HD. Cable and/or DBS is way too compressed.
This isn't an inch thick, but it's good place to start. Charley Rhodes knows his stuff. Read all his papers regarding the crap tuners in DTV receivers, and the fact the FCC assumed much better tuners when they passed out post-transition frequencies. This whole thing may crash and burn next President's Day night, even without these mythical White Space Devices.
