Contribution presented by Chris DiMinico. No other contributions
Consideration of WAP cabling guidelines given in TIA/TSB 162-A. TSB (Technical Service Bulletin)
George Zimmerman suggested that we also look at older versions of the 162 document to see how the lengths may have changed from 162 to 162A.
Clark Carty stated that the majority of installations below ceiling grid with POE power (slide 10 doesn’t show this).
Stephen Sedio asked if we can spread these cables out to improve performance. Chris suggested that in the past, a method is to not use adjacent ports in equipment deployment. Ultimately up to end user.
How critical is the coupling in the first 10m of the cabling where bundling is most likely? Chris commented that it is likely and that separation at the near end helps the equipment end. Far end requires access to the cabling.
Guidelines on mitigation of bundling is offered in TIA/TSB-184.
Action items. Review the contributions and think of other deployment considerations that all agree to review. Then develop channel characteristics and use to solicit outside of IEEE to authenticate the use.
Question on how this work will allow mitigation of alien crosstalk. Suggestion was to have the ad-hoc provide guidelines within given limits, which will probably focus on lengths of cabling within the topologies.
In Europe, there are different uses. We need to verify that the topologies developed and suggested will work internationally.
Amrik Bains has data to present for next meeting.
Meeting on 3/6 is cancelled. Next meeting is 2/27 at 11 EST.
