How to do the actual sensing functions does not belong in a communication standard. What has been proposed, but I do not think that the standard amendment has been finalized, is to make some changes in the signals transmitted by WiFi stations, which would enable those desiring to implement sensing functions with the WiFi equipment to do that, without interfering with the normal communication functions.

So if Intel would create some program for Lunar Lake CPUs, possibly using the internal NPU, for purposes like detecting the room occupancy, that application would not be covered by the WiFi standard, the standard will just enable the creation of such applications and such an application would be equally implementable with any PCIe WiFi card conforming to the new standard, not only with an Intel CNVi card, whicd uses an internal WiFi controller.

However it is correct that there are 2 kinds of Intel WiFi cards that look the same (but they have different part numbers, e.g. AX200 for PCIe and AX201 for CNVi), but one kind of cards are standard PCIe cards that work in any computer, while the other kind of cards (CNVi) works only when connected to compatible Intel laptop CPUs.
