Truth or dare

Incorrect facts

The statement that working devices utilizing spectrum sensing have not been presented to the FCC is false. That a power supply fails does not create interference.

In any event, these are "prototypes" of the spectrum sensing approach desigend to help set technical standards. This is not device certification.

Geolocation, as proposed by Google today, is a separate approach than spectrum sensing that can eliminate any interference with some additional overhead. Spectrum sensing is used today in WiFi and it works.

New America notes that 90% of wireless microphones are used illegally. These new approaches are a way for the wireless microphone industry to "get legal".

Get the facts. Then write.

Good thing nobody made that statement, then!

The first prototype failed to detect and avoid nearby signal, this latest suffered from a power supply failure -- though maybe it subsequently performed ok -- nobody knows because the final results haven't been announced...

I believe Microsoft is claiming that the FCC failed to test the backup unit after the primary experienced a hardware failure.

Microsoft is claiming that their tests prove the devices work and the FCC has signed off on the methodology used to test the effectiveness of the devices.
