I-FHSS, ubuchwepheshe be-frequency hopping spread spectrum, ngaphansi kwesimo sokuvumelanisa kanye nesikhathi esisodwa, yamukela amasignali adluliswa abathwali bebhendi emincane yohlobo oluthile (leli fomu elithile linemvamisa ethile, njll.) kuzo zombili iziphetho. Kumamukeli ongenalo uhlobo oluthile, i-hop...

I-OFDM iphakanyiswe ku-IEEE802.11a. Ngokusekelwe kule ndlela yokushintshashintsha, sidinga ukwazi ukuthi iyini i-OFDM ukuze siqonde izimiso ezihlukene. Yini i-OFDM? I-OFDM iwubuchwepheshe obukhethekile bokushintshwa kwezinkampani eziningi. Lobu buchwepheshe buhlose ukuhlukanisa isiteshi sibe iziteshi ezincane ze-orthogonal, futhi ...

Ungabala kanjani inani le-Wi-Fi 6? Okokuqala, qagela kusukela ekuqaleni kuze kube sekupheleni: Izinga lokudlulisela lizothinteka ngenani lokugeleza kwendawo. Inombolo yamabhithi inkampani yenethiwekhi ngayinye engawadlulisela inombolo yamabhithi anekhodi inkampani ngayinye yenethiwekhi. Izinga lokubhala amakhodi liphezulu, lingcono. Mangaki ...

Okokuqala, masifunde nge-IEEE 802.11ax. Kumfelandawonye we-WiFi, ibizwa nge-WiFi 6, eyaziwa nangokuthi inethiwekhi yendawo engenantambo esebenza kahle kakhulu. Kuyindinganiso yenethiwekhi yendawo engenantambo. I-11ax isekela amabhendi angu-2.4GHz kanye ne-5GHz, futhi ingabuyela emuva ihambisane ne-protoco evame ukusetshenziswa...

802.11n idinga ukuchazwa ngokwehlukana. Njengamanje, imakethe evamile isebenzisa le nqubo yokudlulisa i-WiFi. I-802.11n iyiphrothokholi ejwayelekile yokudlulisa okungenantambo. Kuwubuchwepheshe bokwenza inkathi. Ukubukeka kwayo kwenza izinga lamanethiwekhi angenawaya likhule kakhulu. Ukuze kuthuthukiswe i-t...

Kunemiqondo eminingi kanye nemithethonqubo ebandakanyekayo kumanethiwekhi angenawaya. Ukuze nginikeze wonke umuntu umbono ongcono, ngizochaza ukuhlukaniswa. 1. Ngokuhambisana nenethiwekhi ehlukene, amanethiwekhi angenawaya angahlukaniswa abe: “I-WWAN” imele “inethiwekhi yendawo engenantambo. &...
