802.11Ga / B / G / N / AC Guteza Iterambere

802.11Ga / B / G / N / AC Guteza Iterambere
Kuva irekurwa ryambere rya Wi fi kubaguzi mu 1997, wa Wi fi isanzwe yagiye ihinduka, mubisanzwe byongera umuvuduko no kwagura. Nkuko imirimo yongerewe kuri IEEE yambere 802.11, yavuguruwe binyuze mumagorofa yacyo (802.11b, 802.11g, nibindi)

802.11b 2.4GHZ
802.11b ikoresha inshuro imwe 2.4 ghz nkumwimerere 802.11. Ishyigikira umuvuduko ntarengwa wa The Mbps na metero zigera kuri 150. 802.11B ibigize bihendutse, ariko ubu buryo bufite umuvuduko mwinshi kandi utaranze mu bipimo 802.11. Kandi kubera 802.11b ikora kuri 2.4 ghz, ibikoresho byo murugo cyangwa ibindi 2.4 ghz wi fi sllewks birashobora gutera kwivanga.

802.11A 5GHZ OFDM
Version yavuguruwe "A" yiyi ngingo irasohoka icyarimwe hamwe 802.11b. Ishyiraho ikoranabuhanga rigoye ryitwa OfDdm (kugabanuka kwa ORTHOGNAL GUTANDUKANYE) KUBAZA ibimenyetso simusiga. 802. Kandi umurongo wacyo ni mwinshi kuruta 802.11b, hamwe na theoretical ntarengwa ya mbps 54.
Ushobora kuba utahuye nibikoresho byinshi 802.11 cyangwa router. Ibi ni ukubera ko 802.11b nibihendutse kandi bigenda bikomera kumasoko yabaguzi. 802.11A hakoreshwa cyane cyane kubisabwa mubucuruzi.

802.11G 2.4GHZ OFDM
802.11G bakoresha tekinoroji imwe ya 802.11A. Kimwe na 802.11A, ishyigikira igipimo ntarengwa cya Theoretical cya Mbps 54. Ariko, kimwe na 802.11b, ikorera inshuro rusange ya 2,4 ghz (bityo rero ibabazwa nibibazo bimwe na 802.11b). 802.11g irahujwe na 802.11b: 802.11b irashobora guhuza 802.11g ingingo (ariko kuri 802.11B).
Hamwe na 802.11g, abaguzi bateye intambwe igaragara muri Wi fi yihuta no gukwirakwiza. Hagati aho, ugereranije n'ibisekuru byabanje kubicuruzwa, abaguzi ba Routers bagenda bagenda neza kandi beza, bafite imbaraga zo hejuru no kuvurwa neza.

802.11N (WI Fi 4) 2.4 / 5GHZ Mimo
Hamwe na 802.11n, wi fi yagiye yihuta kandi yizewe. Ishyigikira igipimo ntarengwa cya interineti ya mbps 300 (kugeza kuri 450 mbps mugihe ukoresheje antene eshatu). 802. Ibi birashobora kongera iby'ikigereranyo udasabye amagufwa menshi cyangwa kwandura. 802.11Nrashobora gukora muri 2.4 GHZ na 5 GHZ.

802.111C (WI FI 5) 5GHZ MU-MIMO
802. Kugira ngo iyi mikorere, 802.111 ikora gusa mu itsinda rya 50 gusa, rishyigikira imigezi umunani (ugereranije n'inzuzi enye za 802.111), mukubaka ubugari bwa 80 MHz, kandi ikoresha ikoranabuhanga ryitwa Braimform. Hamwe na Braammning, Antennas irashobora kohereza ibimenyetso bya radio, nuko rero byerekana itaziguye kubikoresho byihariye.

Irindi terambere rikomeye ryo 802.11Ac ni Umukoresha Mukuru (Mu-Mimo). Nubwo Mimo ayobora imigezi myinshi kumukiriya umwe, Mu-Mimo arashobora icyarimwe icyarimwe imigezi ya spatial ku bakiriya benshi. Nubwo mu-mimo ntabwo yongera umuvuduko wumukiriya uwo ari we wese, birashobora kunoza amakuru rusange yinjiza umuyoboro wose.
Nkuko mubibona, Wi fi kumikorere ikomeje guhinduka, hamwe numuvuduko ushobora kuba wegereje umuvuduko wingabo

802.11AX wi fi 6
Muri 2018, Ihuriro rya WiFi ryafashe ingamba zo gutuma amazina asanzwe ya WiFi byoroshye kumenya no gusobanukirwa. Bazahindura ibizaza 80.11AX kuri Wifi6

Wi Fi 6, 6 ni he?
Ibipimo byinshi bikora bya Wi fi birimo intera yo kwanduza, kwipimirwa, ubushobozi bwurusobe, nubuzima bwa bateri. Hamwe no guteza imbere ikoranabuhanga n'ibihe, ibisabwa n'abantu kugirango umuntu yihute na umurongo bagenda hejuru.
Hano hari urukurikirane rwibibazo wa Wi fi gusangira gakondo, nko kwiyongera k'umuyoboro, ubwishingizi buke, kandi bigomba guhora guhindura sside.
Ariko wi fi 6 izazana impinduka nshya: Bitezimbere ubushobozi bwibikoresho hamwe nibikoresho byibikoresho, bishyigikira imiti myinshi umukoresha wihuta, kandi irashobora kwerekana imikorere myiza mubice byimbitse, nubwo nabyo bizana intera ndende hamwe nibiciro byoherejwe hejuru.
Muri rusange, ugereranije nabababanjirije, ibyiza bya WI fi 6 ni "bibiri byo hejuru kandi bifite bibiri":
Umuvuduko mwinshi: Murakoze kumenyekanisha tekinoroji nka uplink mu-mimo, 1024QAMU, umuvuduko ntarengwa wa Wi fi 6 urashobora kugera ku muvuduko wa stroke.
Kwinjira mu rwego rwo hejuru: Iterambere ryingenzi rya Wi fi 6 ni ukugabanya ubwinshi kandi wemerere ibikoresho byinshi kugirango uhuze umuyoboro. Kugeza ubu, wi fi 5 irashobora gushyikirana nibikoresho bine icyarimwe, mugihe wa Wi fi 6 izemerera itumanaho hamwe nibikoresho byinshi icyarimwe. Wi fi 6 ikoresha kandi inshuro nyinshi-kugabana inshuro nyinshi) hamwe nikoranabuhanga ryinshi ryibimenyetso byanditseho ikoranabuhanga rikomoka kuri 5G kugirango dutezimbere ubushobozi bwurusobe.
Ultcy nkeya: Mugukoresha ikoranabuhanga nka ofdma na spatialreuse, wi fil ituma abakoresha benshi boherezwa mu gihe cya buri gihe, bakuraho amarushanwa, kugabanya imikorere, kugabanya imikorere, no kugabanya ubuziranenge. Kuva kuri 30 kuri WI Fi 5 kugeza kuri 20, hamwe no kugabanya umutibamo 33%.
Kunywa ingufu nke: Twt, indi tekinoroji nshya muri wi fi 6, yemerera ap kugirango iganire ku itumanaho na terefone, bikagabanya igihe gisabwa kugirango ukomeze no gushakisha ibimenyetso. Ibi bivuze kugabanya ibiryo bya bateri no kunoza ubuzima bwa bateri, bikavamo kugabanuka kuri 30% mugushira amashanyarazi.
