2. Thandizani 1024-QAM, kuchuluka kwa data
Pankhani ya kusintha kwa WiFi 5 ndi 256-QAM ndi WiFi-6 ndi 1024-QAM, yoyamba imathandizira mitsinje yambiri ya data ya 4 pamene yotsirizirayi imathandizira pazipita 8. Choncho, WiFi 5 ikhoza kukwaniritsa zolemba za 3.5Gbps, pomwe WiFi 6 imatha kupeza 9.6Gbps yodabwitsa.
3. Kuthandizira kwa mtundu wonse wa MU-MIMO
MIMO imatanthawuza ukadaulo wa Multiple Input Multiple Output, womwe umatanthawuza kugwiritsa ntchito ma antennas angapo potumiza ndi kulandira ma antennas pa transmitter ndi wolandila kumapeto motsatana, kotero kuti ma siginecha amatha kufalitsidwa ndikulandilidwa kudzera mu tinyanga zingapo pa transmitter ndi malekezero olandila kuti akwaniritse kuchuluka kwa ogwiritsa ntchito mtengo wocheperako, motero kuwongolera kulumikizana bwino.M'malo mwake, ukadaulo wa MIMO unayambitsidwa ndi IEEE mu nthawi ya protocol ya 802.11n, ndipo ukadaulo wa MU-MIMO ukhoza kumveka ngati mawonekedwe osinthidwa kapena ogwiritsa ntchito ambiri.
M'mawu a layman, MIMO yam'mbuyo pa 802.11n imatha kufotokozedwa ngati SU-MIMO, pomwe ma siginecha amtundu wa SU-MIMO amawonetsedwa mozungulira, kumalumikizana payekhapayekha ndi zida zolumikizira intaneti kuti zitheke.Zida zambiri zikalumikizidwa, padzakhala zida zodikirira kulumikizana;ngati muli ndi 100MHz ya bandiwifi, malinga ndi mfundo yakuti "imodzi yokha ingatumikire panthawi imodzi", ngati pali zipangizo zitatu zomwe zimagwirizanitsidwa ndi intaneti nthawi imodzi, chipangizo chilichonse chikhoza kupeza pafupifupi 33.3MHz ya bandwidth, ndi zina. 66.6MHz ndi yopanda ntchito.Ena 66.6MHz ndi osagwiritsidwa ntchito.Izi zikutanthauza kuti zida zambiri zikalumikizidwa kudera lomwelo la Wi-Fi, kuchuluka kwa bandiwifi kumakhala kocheperako, zinthu zambiri zimawonongeka komanso kuthamanga kwa netiweki kumachepa.
Routa ya MU-MIMO ndi yosiyana, popeza chizindikiro cha MU-MIMO chimagawidwa m'magawo atatu mu nthawi, dera lafupipafupi ndi dera la airspace, ngati kuti zizindikiro zitatu zosiyana zimatulutsidwa nthawi imodzi, ndipo zimatha kugwira ntchito ndi zipangizo zitatu. nthawi yomweyo;makamaka kuyenera kutchulidwa kuti, monga zizindikiro zitatu sizikusokonezana wina ndi mzake, kotero kuti zipangizo za bandwidth zomwe zimalandiridwa ndi chipangizo chilichonse sizingasokonezeke, ndipo zothandizira zimawonjezeka.Kuchokera pakuwona kwa rauta, kuchuluka kwa ma data kumawonjezeka ndi katatu, kupititsa patsogolo kagwiritsidwe ntchito kazinthu zapaintaneti ndikuwonetsetsa kuti kulumikizana kwa Wi-Fi kosasokonekera.
4. luso la OFDMA
OFDM, kapena Orthogonal Frequency Division Multiplexing, ndi njira yotumizira yonyamula zonyamulira zambiri yopangidwa kuchokera kumayendedwe onyamula zinthu zambiri okhala ndi zovuta zochepa zokhazikitsa komanso kugwiritsa ntchito mosiyanasiyana.Kuti tifotokoze ndi chitsanzo chosavuta: tiyerekeze kuti tsopano tili ndi magalimoto ambiri oti tichoke ku A kupita ku B. Asanayambe kugwiritsa ntchito teknoloji ya OFDM, msewu ndi msewu, magalimoto onse amayendetsa mozungulira ndikugwedeza, chifukwa chake, palibe amene angathe kuthamanga. .Tsopano ndi luso la OFDM, msewu waukulu umagawidwa m'njira zambiri ndipo aliyense amayendetsa motsatira njira, zomwe zingawonjezere liwiro komanso kuchepetsa kusokoneza pakati pa magalimoto.Panthaŵi imodzimodziyo, pamene pali magalimoto ochuluka mumsewuwu, amawongoleredwa pang’ono ndi kanjirako ndi magalimoto ochepa, zomwe zimakhala zosavuta kuziwongolera.
Ukadaulo wa OFDMA udachokera ku OFDM powonjezera ukadaulo wogwiritsa ntchito zambiri (mwachitsanzo, ogwiritsa ntchito ambiri).
Yankho la OFDM ndikutumiza galimoto kamodzi kwa kasitomala aliyense.Mosasamala kanthu za kuchuluka kwa katundu, ulendo umodzi umodzi umatumizidwa, zomwe mosakayikira zimabweretsa galimoto yopanda kanthu.Njira ya OFDMA, kumbali ina, idzatumiza maoda angapo palimodzi, kulola magalimoto kuti agunde mumsewu modzaza momwe angathere, zomwe zimapangitsa kuti zoyendera ziziyenda bwino.
Osati zokhazo, koma zotsatira za OFDMA ndi MU-MIMO zitha kuyikidwa pamwamba pa WiFi6.Awiriwa akuwonetsa ubale wogwirizana, pomwe OFDMA ili yoyenera kufalitsa mapaketi ang'onoang'ono kuti apititse patsogolo kagwiritsidwe ntchito ka tchanelo komanso kufalitsa bwino.MU-MIMO, kumbali ina, ndiyoyenera kufalitsa mapaketi akuluakulu, kuonjezera bandwidth yothandiza ya wogwiritsa ntchito m'modzi komanso kuchepetsa latency.
