Highest clock! not data rate.

How would you treat a piece of IT equipment that had say a 10Gbit/s Ethernet port? Do you just treat this as 10GHz, and use that as the highest clock?

I posed that question to the FCC many years ago and got the answer that the transmitter operating frequency now becomes a frequency of the host device. Therefore a device that operates at, say 50 mHz but has a Wi-Fi transmitter installed shall be tested to the frequency specified in 15.33 based on the 2.4GHz radio.

An on-board WiFi device "uses" (non-clock) GHz range frequencies -- internally. That would be an intentional transmitter though and covered by different FCC rule part / EU standards Charlie -----Original Message----- From: Cortland Richmond [mailto:[email protected]] Sent: 29 January 2016 08:57 To: [email protected]<mailto:[email protected]> Subject: Re: [PSES] Highest clock frequency in a device.
