Where as I appreciate your enthusiasm I fail to understand how a super accurate clock source might assist in an Ethernet switch application?
In wireless communications this accurate clock source is used to do neat things like mitigating self interference or to do channel/spectrum re-use.
When it comes to Ethernet communications that occurs on a closed medium such as copper wire there is no apparent need?
I guess the switch would no longer need an NTP server to acquire accurate times for log entries?
If you are asking the switch to somehow control radios connected to it that is pretty much impossible unless we also made the radios?
