Ukuba usifunda rhoqo uya kuyazi loo nto Phakathi kwezinye izinto ezintsha, i-iPhone eya kuboniswa kulo nyaka i-2019 iya kubandakanya inkxaso kunye nomgangatho omtsha weWiFi 6, kubalulekile ukuba siyazi itekhnoloji yezixhobo zethu ezigcina izindlu ukuba sifuna ukufumana okungcono kuyo.
Hlala nathi kwaye ufumanise ukuba kutheni i-WiFi 6 ibaluleke kangaka kwaye wazi izibonelelo zayo ngaphambi kokuboniswa kwe-iPhone ka-2019 eziza kubandakanya obu buchwephesha bulungele ukutshintsha umhlaba. Zininzi izinto ozivileyo ngayo, kodwa lixesha lokuba uyinike uphononongo olunzulu.
Yintoni i-WiFi 6 kwaye kutheni eli gama litsha?
I-WiFi 802.1.ac kunye nezinto ezifanayo ziya kuvakala ziqhelekile kuwe, isihogo esinika igama kuthi abo bahlala behlalutya izixhobo zeentlobo ezahlukeneyo. Mhlawumbi umgangatho we-WiFi kufanelekile ukuba wamkele indlela efanayo nomgangatho weBluetooth kwakudala, leyo uyazi kakuhle ukuba ngamanani kwaye i-odolwe ngokulula ukusuka kokuncinci ukuya ngaphezulu, umzekelo sineBluetooth 4.2, iBluetooth 5.0 njalo njalo. Nangona kunjalo, ngale ndlela intsha yokubiza i-WiFi, into abayifunayo kukuba siyazi ngokukhawuleza nangakumbi ngendlela enomdla ukuba loluphi uhlobo lwenethiwekhi esidityaniswe kuyo ngalo mzuzu kanye ukufumana umbono wobubanzi bebhendi kunye nomgangatho wonxibelelwano ukuya kuthi sizokwazi ukuhamba.
Kwaye kuxhomekeke kakhulu ekubeni sikunethiwekhi ye-2,4 GHz, inethiwekhi ye-5 GHz kunye nomthamo womgca ukuba siza kuba nakho ukuhamba ngokukuko ngokufanelekileyo okanye hayi. Kule meko, i-WiFi 6 yindalo yendalo yenkqubo ye-WiFi ethi ithiyori kufanele ukuba ibizwa ngokuba yi-WiFi 802.11.ax Ngenxa yento yokuba sishiya ngasemva i-WiFi 802.11.ac. Ngendlela efanayo, iinguqulelo zangaphambili zeWiFi ziya kuthi zifumane le ndlela intsha, elula yokuchonga, Oko kukuthi, ngoku i-WiFi 802.11.ac iya kuthiywa igama libe yiWiFi, eya kuthi ivumele olu bhengezo ukuba longezwe ngokulula kwibhar yomgangatho wezixhobo zethu. .
Ngaba i-WiFi 6 iyahambelana nezinye iinguqulelo?
Njengoko besesitshilo, i-WiFi 6 ayikho enye into ngaphandle kokuvela kwendalo ye-WiFi 801.11.ac, njengoko kwenzekile ukuza kuthi ga ngoku, nasiphi na isixhobo I-WiFi 6 iya kuba nakho ukunxibelelana nezihambisi ze-WiFi ezisebenza kwiiprotokholi zangaphambili ezinjengeWiFi 5 (802.11.ac) umzekelo, ngokuchanekileyo kanye ngendlela eyenzeka ngayo ngoqhagamshelo lwe-3G okanye lwe-4G oluguqulayo ngokuxhomekeke kumgangatho wesiginali, okanye kwenzeka ntoni ngezixhobo ezineBluetooth 5.0 ezikwaziyo ukunxibelelana nayo nayiphi na inkqubo ye-Bluetooth.
Nangona kunjalo, ukuze siqaphele uhlobo oluthile lokwahluka kusetyenziswa isixhobo esine-WiFi 6 kubaluleke kakhulu ukuba umthumeli, nokuba ngumzila okanye umphindisi, usebenzisa le nkqubo inye, into eya kuthi ngokungathandabuzekiyo ithathe ixesha elide. Kwaye, umzekelo, kumakhaya ethu sinee-routers ezingazukuhlaziywa kumgaqo omtsha, nangona sihlala sinethuba lokuthatha ukhenketho lweAmazon kwaye sithathe indawo yomzi wenkampani yethu ngokusebenza kakuhle nangaphezulu Intsebenzo inye.
Olu luphuculo lweWiFi 6
Kucacile ukuba ukuvela kweprotocol kuya kudlula ngaphaya kokutshintsha kwegama, umzekelo kukuba u-WiFi uguqulelo 5 (802.11.ac) kude kube ngoku lwalunokusebenza kuphela kumabhendi e-5 GHzKungenxa yoko le nto imizila yethu enebhendi ye-5 GHz zezona zibonelela ngezona ziphumo zibalaseleyo zokuhamba. Nangona kunjalo, ihlala inengxaki, esinendawo encinci. Umgaqo-nkqubo omtsha uya kuphucula noluhlu lweWiFi kwimeko apho ukuhambisa kuhlala kunzima kakhulu, njengezindlu, apho kukho imiqobo emininzi efana nodonga nefenitshala.
- Ukuhanjiswa kwe-WiFi 5 (802.11.ac) 6,9 Gbps
- Ukuhanjiswa kwe-WiFi 6 (802.11.ax) 9,6 Gbps
Enye into eyahlukileyo kukumodareyitha, ngelixa eyona inikezelwe yiWiFi 5 (802.11.ac) ingama-256 - QAM, kwiWiFi 6 siyakufumana ukuya kuthi ga kwi-1024-QAM, ekhokelela kwi-600 Mbps kumjelo ngamnye (80 MHz) ubuninzi bayo I-10.000 Mbps, ukuya kuthi ga kwi-3.000 Mbps ngaphezulu kwento uguqulelo lwangaphambili lwe-WiFi olunakho ukunikela. Ewe kunjalo, uphuculo luya kubambeka ngakumbi xa sinezixhobo ezininzi ezixhumeke kwinethiwekhi enye ye-WiFi, Oko kukuthi, Yenzelwe ukuba ikwazi ukuxhasa zonke iimfuno zeemveliso zekhaya ezi-smart, yiyo loo nto inyani yokuba isebenza kwiibhendi ze-2,4 GHz yenza ukuba ikhetheke kangaka.
Itekhnoloji ye-OFDMA iya kuphucula ukusebenza kakuhle kunye nokusebenza
Usandul 'ukuyifunda, ukusebenza okuphambili, ngaphezulu kwesantya sokuhambisa idatha (ngaphezulu kokuphakama kokusetyenziswa kwekhaya kubasebenzisi esele benama-600/600 eSpain umzekelo) yinto yokuba ukusebenza kungaphuculwa ngokulawula izixhobo ezisebenzisa iifowuni ezikrelekrele inethiwekhi efanayo ye-WiFi. Umgangatho I-OFDMA (I-Orthogonal Frequency Division yokuFikelela okuPhindiweyo) iya kuphucula ukusebenza ngokunikezela ngokulibaziseka okanye ukulibaziseka ekunxibelelaneni nasekusebenzeni komsebenzi. Oku kuya kulawula isebe lesitishi esisetyenziswa yi-router ukuze ingasebenzisi yonke i-bandwidth ekuthumeleni i-odolo kwisixhobo se-IoT okanye kulo naluphi na uhlobo, kwaye ke ngokulawula ngokufanelekileyo umda wendlela wendlela kwizixhobo eziyifuna kakhulu, unazo zonke iingcinga ezisehlabathini.
Uya konga nasekusebenziseni amandla kwesixhobo esamkelayo enkosi kwi-TWT (Ithagethi yokuVusa ixesha), eya kuthi icwangcise amaxesha asengqiqweni onxibelelwano lweWiFi ngesithumeli, endaweni yokwenza ngokuzenzekelayo nangokungahleliwe. Ngokuqinisekileyo, i-WiFi 6 ziindaba ezimnandi kakhulu kwi-iPhone yalo nyaka 2018, kwaye ke, ngokobunye ubuchwephesha kuyinyani ukuba iApple inengxaki yokwamkela amanqaku amatsha, kodwa kwinqanaba le-WiFi ibisoloko iphambili kubo bonke yezixhobo zayo, umzekelo kukwamkelwa kwabo kwangoko kwebhendi ye-5 GHz.Kuba nokuba kunjalo, ikhaya elidityanisiweyo lifumana ukubaluleka okukhethekileyo kunxibelelwano lwethu, ke kufuneka amakhadi enethiwekhi ukuze sihambelane.
