Question about Panasonic KX-TG6824GB / DE

Does this telephone 4-piece set have WLAN? There is nothing in the specifications about this. I have two questions about this landline phone 4-piece set here (Panasonic KX-TG6824GB / DE; item number: 10378466) and a second landline phone 4-piece set from Panasonic (Panasonic KX-TG6724GB; item number: 10378507, https://www.digitec.ch/en/s1/product/panasonic-kx-tg6724gb-phones-10378507 ), both of which are in stock at Digitec.ch/Galaxus.ch. What is the exact difference between the two landline phone 4-piece sets? In particular, I would like to know why the Panasonic KX-TG6724GB has the word "WLAN" listed in the specifications under "Connections", while the Panasonic KX-TG6824GB / DE has no mention of WLAN or lacks the heading "Connections". This is also noticeable when you directly compare the two products using the comparison functionality. The two phones seem to be otherwise quite similar, but are sold with different frequencies (sales rank 92 vs. 239). I also asked the same question about the other product, so please check there for an answer. Thank you very much for answering my question! Note: The question about the difference between the two phones has already been asked here in the Question Forum (see above), where the WLAN was not addressed.
