WiFi 7 (Wi-Fi 7) niyo isanzwe ya Wi-Fi yo mu gisekuru gitaha. Ihuye na IEEE 802.11, hagiye gushyirwa ahagaragara isanzwe nshya ya IEEE 802.11be – Extremely High Throughput (EHT)
Wi-Fi 7 izanye ikoranabuhanga nka bandwidth ya 320MHz, 4096-QAM, Multi-RU, imikorere ya multi-link, MU-MIMO yarushijeho kuba nziza, n'ubufatanye bwa multi-AP hashingiwe kuri Wi-Fi 6, bituma Wi-Fi 7 igira imbaraga kurusha Wi-Fi 7. Kubera ko Wi-Fi 6 izatanga igipimo cyo kohereza amakuru kiri hejuru kandi ikaba nto. Biteganijwe ko Wi-Fi 7 izafasha mu gutanga umusaruro ugera kuri 30Gbps, hafi inshuro eshatu ugereranyije na Wi-Fi 6.
Ibintu Bishya Bishyigikiwe na Wi-Fi 7
- Ifasha umuyoboro ntarengwa wa 320MHz
- Gushyigikira uburyo bwa Multi-RU
- Gushyiraho ikoranabuhanga ryo guhindura 4096-QAM mu buryo bwo hejuru
- Shyiraho uburyo bwo guhuza amasano menshi (Multi-Link)
- Shyigikira uburyo bwo gukwirakwiza amakuru menshi, kunoza imikorere ya MIMO
- Gushyigikira gahunda y'amakoperative hagati y'abashinzwe AP benshi
- Imiterere y'ikoreshwa rya Wi-Fi 7
1. Kuki Wi-Fi 7 ikoreshwa?
Bitewe n'iterambere ry'ikoranabuhanga rya WLAN, imiryango n'ibigo byishingikiriza cyane kuri Wi-Fi nk'uburyo bw'ingenzi bwo kugera kuri interineti. Mu myaka ya vuba aha, porogaramu nshya zifite ibisabwa byinshi byo gukoresha no gutinda, nka videwo ya 4K na 8K (igipimo cyo kohereza amakuru gishobora kugera kuri 20Gbps), VR / AR, imikino (igisabwa cyo gutinda ni munsi ya 5ms), ibiro biri kure, na videwo kuri interineti na cloud computing, nibindi. Nubwo isohoka rya vuba rya Wi-Fi 6 ryibanze ku bunararibonye bw'abakoresha mu bihe by'ubucucike bwinshi, ntirishobora kuzuza neza ibisabwa hejuru byavuzwe haruguru byo gukoresha no gutinda.

Muri urwo rwego, ikigo gisanzwe cya IEEE 802.11 kiri hafi gushyira ahagaragara ivuguruye rya IEEE 802.11be EHT, ari ryo Wi-Fi 7.
2. Igihe cyo gusohora Wi-Fi 7
Itsinda rishinzwe gukora rya IEEE 802.11be EHT ryashinzwe muri Gicurasi 2019, kandi iterambere rya 802.11be (Wi-Fi 7) riracyakomeje. Ihame ry’imikorere yose rizasohoka mu majwi abiri, kandi Release1 biteganijwe ko izasohora verisiyo ya mbere muri 2021. Draft Draft1.0 biteganijwe ko izasohora ihame mu mpera za 2022; Release2 biteganijwe ko izatangira mu ntangiriro za 2022 ikarangiza ihame ry’imikorere mu mpera za 2024.
3. Wi-Fi 7 ugereranije na Wi-Fi 6
Hashingiwe ku gipimo cya Wi-Fi 6, Wi-Fi 7 izana ikoranabuhanga rishya, ahanini rigaragarira muri ibi bikurikira:
4. Ibintu bishya bishyigikiwe na Wi-Fi 7
Intego ya protocole ya Wi-Fi 7 ni ukongera igipimo cy’umuyoboro wa WLAN kikagera kuri 30Gbps no gutanga garanti yo kwinjira mu buryo butaziguye. Kugira ngo iyi ntego igerweho, protocole yose yakoze impinduka zijyanye na PHY layer na MAC layer. Ugereranyije na protocole ya Wi-Fi 6, impinduka zikomeye za tekiniki zazanywe na protocole ya Wi-Fi 7 ni izi zikurikira:
Ifasha Bandwidth ntarengwa ya 320MHz
Interineti idafite uruhushya muri 2.4GHz na 5GHz iba ifite umubare muto kandi yuzuye. Iyo Wi-Fi isanzwe ikoresha porogaramu zigezweho nka VR/AR, nta kabuza izahura n'ikibazo cya QoS nke. Kugira ngo intego yo kugera ku muvuduko ntarengwa wa 30Gbps igerweho, Wi-Fi 7 izakomeza gushyiraho frequency band ya 6GHz no kongeramo uburyo bushya bwa bandwidth, harimo 240MHz ihoraho, 160+80MHz idahoraho, 320 MHz ihoraho na 160+160MHz idahoraho.

Gushyigikira Uburyo bwa Multi-RU
Muri Wi-Fi 6, buri mukoresha ashobora kohereza cyangwa kwakira amafoto kuri RU yihariye yagenwe, ibi bikaba bigabanya cyane uburyo bwo guhuza imiterere y’umutungo wa spectrum. Kugira ngo iki kibazo gikemuke kandi kirusheho kunoza imikorere ya spectrum, Wi-Fi 7 isobanura uburyo bwemerera RU nyinshi ku mukoresha umwe. Birumvikana ko kugira ngo habeho kuringaniza uburyo bwo gushyira mu bikorwa no gukoresha spectrum, protocole yashyizeho amabwiriza amwe ku guhuza RU, ni ukuvuga: RU nto (RU ntoya kurusha 242-Tone) zishobora guhuzwa gusa na RU ntoya, naho RU nini (RU nini kurusha cyangwa zingana na 242-Tone) zishobora guhuzwa gusa na RU nini, kandi RU ntoya na RU nini ntizemerewe kuvangwa.
Gushyiraho ikoranabuhanga ryo guhindura 4096-QAM mu buryo bwo hejuru
Uburyo bwo guhindura ibintu mu buryo buhanitse cyaneWi-Fi 6ni 1024-QAM, aho ibimenyetso bya modulation bigira biti 10. Kugira ngo wongere umuvuduko, Wi-Fi 7 izashyiraho 4096-QAM, bityo ibimenyetso bya modulation bigira biti 12. Muri ubwo buryo bumwe bwo gusimbuza, Wi-Fi 7's 4096-QAM ishobora kugera ku kigero cya 20% ugereranije na Wi-Fi 6's 1024-QAM. (Murakaza neza kuri konti yemewe: injeniyeri w’umuyoboro Aaron)
Shyiraho uburyo bwo guhuza amasano menshi (Multi-Link)
Kugira ngo haboneke ikoreshwa ryiza ry’umutungo wose uboneka wa spectrum, hakenewe byihutirwa gushyiraho uburyo bushya bwo gucunga, guhuza no kohereza amakuru kuri 2.4 GHz, 5 GHz na 6 GHz. Itsinda rishinzwe ryagennye ikoranabuhanga rijyanye no guteranya amakuru menshi, cyane cyane harimo imiterere ya MAC yo guteranya amakuru menshi, uburyo bwo kugera ku miyoboro myinshi, kohereza amakuru menshi n’andi makoranabuhanga ajyanye nayo.
Shyigikira uburyo bwo gukwirakwiza amakuru menshi, kunoza imikorere ya MIMO
Muri Wi-Fi 7, umubare w'imiyoboro y'itumanaho yariyongereye uva kuri 8 ugera kuri 16 muri Wi-Fi 6, ibi bikaba bishobora gukuba kabiri igipimo cyo kohereza amakuru gifatika. Gushyigikira imiyoboro myinshi y'itumanaho bizana MIMO ifite ibintu byinshi bikomeye, bivuze ko imiyoboro 16 y'itumanaho ishobora gutangwa atari ahantu hamwe ho kwinjira, ahubwo n'ahantu henshi ho kwinjira icyarimwe, bivuze ko AP nyinshi zigomba gukorana kugira ngo zikore.
Gushyigikira gahunda y'amakoperative hagati y'abashinzwe AP benshi
Muri iki gihe, muri gahunda ya 802.11, nta bufatanye buhagije buri hagati ya AP. Imirimo isanzwe ya WLAN nko gutunganya ibintu mu buryo bwikora no kurohama mu buryo bwihuse ni ibintu bigenwa n'abacuruzi. Intego y'ubufatanye hagati ya AP ni ukunoza gusa guhitamo imiyoboro, guhindura umutwaro hagati ya AP, nibindi, kugira ngo intego yo gukoresha neza no gushyira hamwe umutungo wa radiyo. Gahunda ihuriweho hagati ya AP nyinshi muri Wi-Fi 7, harimo igenamigambi rihuriweho hagati y'uturemangingo mu gice cy'igihe n'igice cy'umuyoboro, guhuza imikoranire hagati y'uturemangingo, na MIMO ikwirakwizwa, bishobora kugabanya imikoranire hagati ya AP, kunoza cyane ikoreshwa ry'umutungo wa interineti y'umwuka.
Ese?
Hari uburyo bwinshi bwo guhuza gahunda hagati ya AP nyinshi, harimo C-OFDMA (Coordinated Orthogonal Frequency-Division Multiple Access), CSR (Coordinated Spatial Reuse), CBF (Coordinated Beamforming), na JXT (Joint Transmission).
5. Imiterere y'ikoreshwa rya Wi-Fi 7
Ibintu bishya byashyizweho na Wi-Fi 7 bizongera cyane igipimo cyo kohereza amakuru kandi bitange uburibwe buke, kandi izi nyungu zizafasha cyane porogaramu zishya, nk'uko bikurikira:
- Videwo ikoreshwa mu gushakisha amashusho
- Ikiganiro cya Videwo/Ijwi
- Imikino idafite umugozi
- Ubufatanye mu gihe nyacyo
- Imikoreshereze ya mudasobwa mu bicu/mu bicu
- interineti y'inganda y'ibintu
- AR/VR inyura mu buryo bwimbitse
- ubuvuzi bushingiye ku ikoranabuhanga
