16891 802.19 comment from Benjamin Rolfe: Of particular interest is coexistence impacts in the 6 GHz band, where previously 802.11 has not operated and previous coexistence analysis has not covered. The 802.15.4 LRP and HRP UWB PHYs operate in this band. Include analysis of the impacts of these services on 802.11ax (likely none) and the impacts of 802.11ax on these services. In particular, the only mitigation method given, CCA, a reasonable question is will the current CCA mechanisms detect UWB signals (which seems likely not), and analysis including expected performance impacts (PER, latency, etc.) as well as mitigation factors and techniques other than CCA and CSMA which may apply. Complete analysis as described in the comment Rejected This is not a comment on the draft amendment, however with respect to the CA document: The IEEE 802 LMSC OPERATIONS MANUAL states as follows "The CA document shall address coexistence with all relevant approved IEEE 802 LMSC wireless standards specifying devices for unlicensed operation. The WG should consider other specifications in their identified target band(s) in the CA document." 802.11 coexistence with non-802.11 systems is addressed in Section 3 of the CA document. There is no LMSC requirement for analysis or simulation or testing. CA document has been amended to acknowledge UWB with the relevant regulations. Refer to
