Channel definitions ad hoc minutes October 31

(1)Reviewed patent policy

(2)Reviewed October 24 minutes

(3)Review action items

>>> Todd Herman to provide connector and cable information that was used in presentation modeling - No objection to RL proposal inclusion in baseline

(4)Review action plan optional Link Segment

The 802.3bp chair asked the ad hoc to focus on closing the 15 meter segment baseline. We will hold off on the optional link segment discussion till the 15 meter baseline is adopted.(5)Measurement data collection – format frequency (1 MHz) spacing and frequency range

(1 MHz – 600 MHz) touchstone files.

>>>No objection to measurement touchstone format and frequency range during discussion

>>>NOTE: Like to open this discussion to consider measurement frequency

range of data collection to 1 GHz.
