16902 802.19 comment from Billy Verso: In this clause are lots of techniques to make very high density of use of the band, which is good for 2.4 and 5GHz bands where CCA is an effectrive coexistance mechanism. However if this is translated into the 6 to 7 GHz band, I fear that any coexisting systems using 802.15.4 HRP UWB or LRP UWB PHYs will cease to operate effectively. This is worrying because these systems are critical in applications such as: robot guidance, factory automation, hospital security/safety, automotive keyless entry, safety of personnel around machines, first responder location etc. Include coexistance mechanisms for these 802.15 UWB deployments or remove the channels from the 11ax amendment that cover 6 to 7 GHz band. Rejected This is not a comment on the 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
