WiFi 6, ibihe 5G muri WiFi

WiFi 6, ibihe 5G muri WiFi Ubusobanuro bukomeye bwikoranabuhanga rya WiFi 6, ndatekereza ko iyi subtitle ishobora kuba igereranya rikwiye.Ni ibihe bintu bitatu by'ingenzi biranga 5G?"Ultra-high bandwidth, ultra-low lattency and ultra-large capacity" - ibi bigomba kumenyera buriwese, byumvikane ko hariho uburyo bworoshye bwo kubona imiyoboro, gukata imiyoboro (NBIoT, eMTC, eMMB) kugirango ugere kumurongo uhagije no gukoresha umurongo mugari, ibyo biranga bituma 5G itandukanye rwose na 4G igisekuru gishya cyikoranabuhanga ryitumanaho, niyo mpamvu "4G ihindura ubuzima, 5G ihindura societe".Reka turebe kuri WiFi 6. Hashobora kubaho iterambere ryinshi, kandi uyu mugozi winyuguti wahindutse IEE802.11a / b / g / n / ac / axe, ukurikirwa na ay.Ku ya 4 Ukwakira 2018, Ihuriro rya WiFi rishobora kandi kumva ko iri zina ritari ryiza mu kumenyekanisha abaguzi, bityo ryahinduye uburyo bwo kwita izina rya “WiFi + nimero”: IEEE802.11n kuri WiFi 4, IEEE802.11ac kuri WiFi 5 , na IEEE802.11ax kuri WiFi 6. Inyungu yo guhindura izina, birumvikana ko kumenya byoroshye, umubare munini, umubare munini w'ikoranabuhanga, kandi byihuse umuyoboro.Nubwo, nubwo umurongo wa tewolojiya ya tekinoroji ya WiFi 5 ushobora kugera kuri 1732Mbps (munsi ya 160MHz) hejuru kurenza umuvuduko wa enterineti kumurongo mugari usanzwe murugo 50 500Mbps, mugukoresha burimunsi turacyasanga harigihe hariho "imiyoboro y'amahimbano", ni ukuvuga ibimenyetso bya WiFi byuzuye.Kugera kumurongo birihuta nkaho interineti yaciwe.Ibi bintu birashobora kuba byiza murugo, ariko birashoboka cyane ko bibera ahantu hahurira abantu benshi nko mubiro, ahacururizwa hamwe n’ahantu hateranira.Iki kibazo kijyanye na tekinoroji ya WiFi mbere ya WiFi 6: WiFi yabanje yakoresheje OFDM - tekinoroji ya orthogonal frequency division multiplexing tekinoroji, ishobora gushyigikira neza abakoresha benshi, nka MU-MIMO, abakoresha benshi-benshi-binjiza-nibisohoka byinshi , ariko munsi ya WiFi 5, abakoresha bagera kuri bane barashobora gushyigikirwa na MU-MIMO.Byongeye kandi, kubera ikoreshwa rya tekinoroji ya OFDM mugukwirakwiza, mugihe hari umurongo munini wa porogaramu isabwa mubakoresha bahujwe, bizazana igitutu kinini kumurongo wose utagira umugozi, kuko iki cyifuzo kinini cyumukoresha umwe ntabwo gifata umurongo mugari gusa .Kurugero, murugo, niba umuntu akuyemo inkuba, noneho imikino yo kumurongo biragaragara ko izumva ubwiyongere bwubukererwe, nubwo umuvuduko wo gukuramo utagera kumurongo wo hejuru wogukoresha umurongo mugari murugo, bikaba murwego runini

Incamake yuburyo bugezweho bwikoranabuhanga muri WIFI 6

Kuva ryavumburwa, agaciro kayo gakoreshwa nagaciro k’ubucuruzi byamenyekanye cyane ninganda, kandi byakoreshejwe mubikoresho bigendanwa hafi ya byose hamwe nibidukikije murugo.Mugihe imibereho yabantu ikomeje gutera imbere, tekinoroji ya W i F ihora ihindagurika kugirango itange abakoresha uburambe bwiza bwo kubona.2 0 1 Imyaka 9, umuryango W i F i wakiriye umunyamuryango mushya, tekinoroji ya W i F i 6 yavutse.

Ibikoresho bya tekinike ya WIFI

1.1 Igice cya Orthogonal Frequency Igice Cyinshi Kugera

W. igipimo.Iyo imiyoboro imwe-imwe ikoreshwa, igipimo ntarengwa cya W i F i 6 ni 9,6 G bit / s, ni 4 0% hejuru ya W i F i 5. (W i F i 5 igipimo ntarengwa cya 6.9 Gbit / s).Inyungu zayo nini ni uko igipimo cyo hejuru gishobora kugabanywa muri buri gikoresho kiri murusobe, bityo bikongerera igipimo cya buri gikoresho kuri neti.

1.2 Abakoresha benshi-binjiza byinshi-bisohoka tekinoroji

W i F i 6 ikubiyemo kandi Multi-Umukoresha Winshi Yinjiza Byinshi Ibisohoka (MU - MIMO).Iri koranabuhanga rituma ibikoresho bisubiza icyarimwe kubintu bidafite umugozi birimo antenne nyinshi, bituma ingingo zo kwinjira zihita zishyikirana nibikoresho byinshi.Muri W i F i 5, ingingo zo kwinjira zirashobora guhuzwa nibikoresho byinshi icyarimwe, ariko ibyo bikoresho ntibishobora gusubiza icyarimwe. 

1.3 Intego yo gukanguka igihe cyikoranabuhanga

Intego yo gukanguka (TWT, TARGETWAKETIME) TEKINOLOGIYA NIKORANABUHANGA RY'IKORANABUHANGA RY'IKORANABUHANGA RYA W i F i 6, iryo koranabuhanga ryemerera ibikoresho kuganira igihe nigihe cyo kubyuka kugirango wohereze cyangwa wakire amakuru, kandi aho utagera utagira umugozi urashobora guterana ibikoresho byabakiriya muburyo butandukanye bwa TWT, bityo bigabanya umubare wibikoresho bihatanira imiyoboro idafite umugozi icyarimwe nyuma yo kubyuka.Tekinoroji ya TWT nayo yongerera igihe cyo gusinzira igikoresho, itezimbere cyane ubuzima bwa bateri kandi igabanya ingufu za terefone.Dukurikije imibare, ikoreshwa rya tekinoroji ya TWT rishobora kuzigama hejuru ya 30% y’amashanyarazi akoreshwa, kandi bifasha cyane ikoranabuhanga rya W i F i 6 kugira ngo ryuzuze ingufu nke zikoreshwa n’amashanyarazi ya IoT. 

1.4 Serivisi yibanze yashyizeho uburyo bwo gusiga amabara

Kugirango tunoze imikorere rusange ya sisitemu mubidukikije byuzuye, tumenye imikoreshereze myiza yumutungo wa spekure, kandi ukemure ikibazo cyo kwivanga kwumuyoboro, W i F i 6 yongeyeho uburyo bushya bwo kohereza imiyoboro ishingiye kuri ibisekuruza byabanjirije ikoranabuhanga, aribyo serivisi yibanze yashyizeho amabara (BSSSC ooooring).Mugushyiramo BSSC oooring imirima kumutwe kumakuru "yanduza" amakuru atandukanye ya serivise yibanze (BS S), uburyo butanga ibara kuri buri muyoboro, kandi uwakiriye ashobora kumenya ikimenyetso cyo guhuza imiyoboro hakiri kare ukurikije BSSSCOOORING FIELD OF UMUYOBOZI W'ISOKO KANDI UREKE KUBONA, IRINDE GUSOHORA NO GUKORA IGIHE.Muri ubu buryo, niba imitwe yakiriwe ifite ibara rimwe, ifatwa nkikimenyetso kibangamira muri 'BSS imwe, kandi kohereza bizatinda;Ku rundi ruhande, hafatwa ko nta kwivanga hagati yibi byombi, kandi ibimenyetso byombi birashobora koherezwa kumuyoboro umwe na frequence.

2 Ibisanzwe bisanzwe bya tekinoroji ya WiFi 6 

2.1 Umuyoboro mugari wa videwo nini

Hamwe nogukomeza kunoza ibyo abantu bakeneye muburambe bwa videwo, bitrate ya serivise zitandukanye za videwo nazo ziragenda ziyongera, kuva SD kugeza HD, kuva 4K kugeza 8K, hanyuma amaherezo kugeza kuri videwo ya VR.Ariko, hamwe nibi, ibyifuzo byogukwirakwiza byiyongereye, kandi kuzuza ibisabwa byogukwirakwiza amashusho byabaye ikibazo gikomeye kuri serivisi za videwo.Imirongo ya 2.4GH z na 5G H z irabana, kandi 5G H z ishyigikira umurongo wa 160M H z ku gipimo kigera kuri 9,6 G bit / s.Itsinda rya 5G H z rifite intera nkeya kandi irakwiriye kohereza serivisi za videwo. 

2.2 Abakoresha serivisi zidatinze nkimikino yo kumurongo

Serivise yimikino yo kumurongo ni serivisi zikorana cyane kandi zifite ibisabwa byinshi kumurongo mugari no gutinda.Cyane cyane kumikino VR igaragara, inzira nziza yo kuyigeraho ni W i F i simsiz.Umuyoboro wa OFDMA ukata tekinoroji ya W i F i 6 urashobora gutanga umuyoboro wihariye wimikino, kugabanya ubukererwe, no kuzuza ibisabwa muri serivisi zimikino, cyane cyane serivise yimikino ya VR, kugirango ubuziranenge bwogukwirakwiza. 

2.3 Urugo rwubwenge rwubwenge guhuza

Ubwenge bwubwenge nigice cyingenzi mubikorwa byubucuruzi bwurugo nkurugo rwubwenge numutekano wubwenge.Ubu buryo bwo guhuza urugo bugezweho bufite aho bugarukira, kandi tekinoroji ya W i F i 6 izazana amahirwe yo guhuriza hamwe tekinike murugo rwubwenge.Ihindura uburyo bwo guhuza ubucucike buri hejuru, umubare munini wokugera, gukoresha ingufu nke nibindi biranga, kandi mugihe kimwe birashobora guhuzwa na terefone zitandukanye zigendanwa zikoreshwa cyane nabakoresha, zitanga imikoranire myiza. 

Nka tekinoroji ya LAN igaragara mu myaka yashize, tekinoroji ya WiFi6 itoneshwa nabantu kubera umuvuduko mwinshi, umuvuduko mwinshi, ubukererwe buke no gukoresha ingufu nke, kandi irashobora gukoreshwa cyane mumashusho, imikino, urugo rwubwenge nibindi bintu byubucuruzi, bitanga byinshi korohereza ubuzima bwabantu.
