Ngo-2018, i-WiFi Alliance ibhengeze i-WiFi 6, isizukulwana esitsha, esikhawulezayo se-WiFi esakha kwisakhelo esidala (i-802.11ac iteknoloji).Ngoku, emva kokuqala kokuqinisekisa izixhobo ngoSeptemba ka-2019, ifikile neskimu samagama esitsha ekulula ukusiqonda kunobizo oludala.
Ngenye imini kwikamva elikufutshane, uninzi lwezixhobo zethu eziqhagamshelweyo ziya kuba yi-WiFi 6 esebenzayo.Umzekelo, i-Apple iPhone 11 kunye ne-Samsung Galaxy Notes sele zixhasa i-WiFi 6, kwaye siyibonile i-Wi-Fi CERTIFIED 6™ iirotha zisandula ukuvela.Yintoni esinokuyilindela ngomgangatho omtsha?
Itekhnoloji entsha ibonelela ngophuculo lonxibelelwano lwe-WiFi 6 izixhobo ezinikwe amandla ngelixa ugcina ukuhambelana ngasemva kwizixhobo ezindala.Isebenza bhetele kwiindawo ezinoxinano oluphezulu, ixhasa umthamo owandisiweyo wezixhobo, iphucula ubomi bebhetri yezixhobo ezihambelanayo, kwaye iqhayisa ngamazinga aphezulu okudluliselwa kwedatha kunangaphambili.
Nantsi ukucazululwa kwemigangatho yangaphambili.Qaphela ukuba iinguqulelo ezindala zonyulwe ngokuhlaziyiweyo izikimu zamagama, nangona kunjalo, azisasetyenziswa ngokubanzi:
WiFi 6ukuchonga izixhobo ezixhasa i-802.11ax (ikhutshwe ngo-2019)
WiFi 5ukuchonga izixhobo ezixhasa i-802.11ac (ikhutshwe ngo-2014)
WiFi 4ukuchonga izixhobo ezixhasa i-802.11n (ikhutshwe ngo-2009)
WiFi 3ukuchonga izixhobo ezixhasa i-802.11g (ikhutshwe ngo-2003)
WiFi 2ukuchonga izixhobo ezixhasa i-802.11a (ikhutshwe ngo-1999)
WiFi 1ukuchonga izixhobo ezixhasa i-802.11b (ikhutshwe ngo-1999)
WiFi 6 vs WiFi 5 isantya
Kuqala, makhe sithethe ngokuphuhla kwethiyori.Njengoko i-Intel ibeka, "i-Wi-Fi 6 iyakwazi ukugqithisa okuphezulu kwe-9.6 Gbps kuwo wonke amajelo amaninzi, xa kuthelekiswa ne-3.5 Gbps kwi-Wi-Fi 5."Ngokwethiyori, i-WiFi 6 umzila okwaziyo ukubetha isantya ngaphezulu kwe-250% ngokukhawuleza kunezixhobo zangoku ze-WiFi 5.
Isantya esiphezulu sesakhono se-WiFi 6 sibulela kubuchwepheshe obufana ne-orthogonal frequency division multiple access (OFDMA);MU-MIMO;i-beamforming, eyenza amazinga aphezulu edatha kuluhlu olunikiweyo ukwandisa umthamo wenethiwekhi;kunye ne-1024 ye-quadrature amplitude modulation (QAM), eyandisa i-throughput yokuvela, usetyenziso olunzulu lwe-bandwidth ngokufaka ikhowudi yedatha eninzi kwinani elifanayo le-spectrum.
Kwaye ke kukho iWiFi 6E, iindaba ezimnandi zokuxinana kwenethiwekhi
Olunye ukongeza kwi-WiFi "uphuculo" yi-WiFi 6E.Ngomhla wama-23 ku-Epreli, i-FCC yenza isigqibo esiyimbali sokuvumela ukusasazwa ngaphandle kwelayisensi phezu kwebhendi ye-6GHz.Oku kusebenza ngendlela efanayo ukuba i-router yakho ekhaya inokusasaza ngaphezulu kweebhendi ze-2.4GHz kunye ne-5GHz.Ngoku, izixhobo ezisebenzayo zeWiFi 6E zinebhendi entsha eneseti entsha yeetshaneli zeWiFi ukunciphisa ukuxinana kwenethiwekhi kunye neempawu eziwisiweyo:
"I-6 GHz ijongana nokunqongophala kwe-Wi-Fi spectrum ngokubonelela ngeebhloko ze-spectrum ezidibeneyo ukuze zikwazi ukuhlalisa i-14 yeziteshi ze-80 MHz ezongezelelweyo kunye neziteshi ezi-7 ezongezelelweyo ze-160 MHz ezifunekayo kwizicelo eziphezulu ze-bandwidth ezifuna ukuhanjiswa kwedatha ngokukhawuleza okunjengokusasazwa kwevidiyo ephezulu kunye nenyani yenyani. . Izixhobo ze-Wi-Fi 6E ziya kusebenzisa amajelo abanzi kunye nomthamo owongezelelweyo wokuhambisa ukusebenza kwenethiwekhi okukhulu."-Umanyano lweWiFi
Esi sigqibo siphantse siphindaphindeka kane isixa se-bandwidth ekhoyo kusetyenziso lwe-WiFi kunye nezixhobo ze-IoT-1,200MHz ye-spectrum kwibhendi ye-6GHz ekhoyo ukuze isetyenziswe ngaphandle kwelayisensi.Ukubeka oku ngokwembono, iibhendi ze-2.4GHz kunye ne-5GHz ezidityanisiweyo ngoku zisebenza ngaphakathi malunga ne-400MHz yespectrum engagunyaziswanga.
