WiFi 7 (Wi-Fi 7) nigisekuru kizaza cya Wi-Fi. Bihuye na IEEE 802.11, ibipimo bishya byavuguruwe IEEE 802.11be - Byinjira cyane (EHT) bizasohoka
Wi-Fi 7 itangiza ikoranabuhanga nka 320MHz yumurongo mugari, 4096-QAM, Multi-RU, imikorere ihuza abantu benshi, yongerewe MU-MIMO, nubufatanye bwa AP-ishingiye kuri Wi-Fi 6, bituma Wi-Fi 7 ikomera kuruta Wi-Fi 7. Kuberako Wi-Fi 6 izatanga ibiciro byo kohereza amakuru hamwe nubukererwe buke. Biteganijwe ko Wi-Fi 7 izashyigikira ibicuruzwa bigera kuri 30Gbps, bikubye inshuro eshatu ibyo Wi-Fi 6.
Ibintu bishya bishyigikiwe na Wi-Fi 7
- Shyigikira umurongo ntarengwa wa 320MHz
- Shyigikira uburyo bwa Multi-RU
- Kumenyekanisha urwego rwo hejuru 4096-QAM tekinoroji yo guhindura
- Menyekanisha uburyo bwinshi-buhuza uburyo bwinshi
- Shyigikira amakuru menshi, kuzamura imikorere ya MIMO
- Shigikira gahunda ya koperative muri AP nyinshi
- Ikoreshwa rya Porogaramu ya Wi-Fi 7
1. Kuki Wi-Fi 7?
Hamwe niterambere ryikoranabuhanga rya WLAN, imiryango ninganda bishingikiriza cyane kuri Wi-Fi nkuburyo nyamukuru bwo kugera kumurongo. Mu myaka yashize, porogaramu nshya zifite ibicuruzwa byinshi byinjira kandi bitinda, nka videwo ya 4K na 8K (igipimo cyo kohereza gishobora kugera kuri 20Gbps), VR / AR, imikino (icyifuzo cyo gutinda kiri munsi ya 5m), ibiro bya kure, hamwe n’inama za videwo kuri interineti. na comptabilite yibicu, nibindi Nubwo gusohora kwa Wi-Fi 6 byibanze kuburambe bwabakoresha murwego rwo hejuru cyane, ntibishobora kuzuza byuzuye ibisabwa hejuru byavuzwe haruguru kugirango byinjizwe kandi bitinde.

Kugira ngo ibyo bishoboke, umuryango usanzwe wa IEEE 802.11 ugiye gusohora ibipimo bishya byavuguruwe IEEE 802.11be EHT, aribyo Wi-Fi 7.
2. Kurekura igihe cya Wi-Fi 7
Itsinda ryakazi rya IEEE 802.11be EHT ryashinzwe muri Gicurasi 2019, kandi iterambere rya 802.11be (Wi-Fi 7) riracyakomeza. Ibipimo byose bya protocole bizasohoka muri Release ebyiri, kandi biteganijwe ko Release1 izasohoka verisiyo yambere muri 2021 Draft Draft1.0 biteganijwe ko izasohoka ibipimo bitarenze impera za 2022; Biteganijwe ko Release2 izatangira mu ntangiriro za 2022 ikarangiza gusohora bisanzwe mu mpera za 2024.
3. Wi-Fi 7 vs Wi-Fi 6
Ukurikije Wi-Fi 6 isanzwe, Wi-Fi 7 itangiza tekinolojiya mishya myinshi, igaragara cyane muri:
4. Ibintu bishya bishyigikiwe na Wi-Fi 7
Intego ya protocole ya Wi-Fi 7 ni ukongera igipimo cyinjira cyumuyoboro wa WLAN kugera kuri 30Gbps no gutanga ingwate zo kwinjira vuba. Kugirango ugere kuriyi ntego, protocole yose yakoze impinduka zijyanye na PHY layer na MAC layer. Ugereranije na protocole ya Wi-Fi 6, impinduka zingenzi za tekiniki zazanywe na protocole ya Wi-Fi 7 nizo zikurikira:
Shyigikira Umuyoboro ntarengwa wa 320MHz
Uruhushya rutagira uruhushya muri 2.4GHz na 5GHz yumurongo wa bande ni muto kandi wuzuye. Iyo Wi-Fi ihari ikoresha porogaramu zigaragara nka VR / AR, byanze bikunze izahura nikibazo cya QoS nkeya. Kugirango ugere ku ntego yo kwinjiza ntarengwa ya 30Gbps, Wi-Fi 7 izakomeza kumenyekanisha umurongo wa 6GHz kandi yongereho uburyo bushya bwagutse, harimo 240MHz ikomeza, idahoraho 160 + 80MHz, ikomeza 320 MHz na non -komeza 160 + 160MHz. (Murakaza neza kwitondera konti yemewe: injeniyeri y'urusobe Aaron)
Shyigikira uburyo bwa Multi-RU
Muri Wi-Fi 6, buri mukoresha arashobora kohereza cyangwa kwakira amakadiri kuri RU yihariye yashizweho, bigabanya cyane guhinduka kwimikorere yumutungo uteganijwe. Kugira ngo iki kibazo gikemuke kandi urusheho kunoza imikorere ya Wi-Fi 7 isobanura uburyo butuma RU nyinshi zigenerwa umukoresha umwe. Byumvikane ko, kugirango uburinganire bugoye bwo gushyira mubikorwa no gukoresha imikoreshereze, protocole yashyizeho amategeko abuza guhuza RUs, ni ukuvuga: RU ntoya (RUs ntoya ya 242-Tone) irashobora guhuzwa gusa hamwe na RU ntoya, hamwe na RU nini (RUs irenze cyangwa ingana na 242-Tone) irashobora guhuzwa gusa na RU nini nini, kandi RU nini nini na RU nini ntabwo byemewe kuvangwa.
Kumenyekanisha urwego rwo hejuru 4096-QAM tekinoroji yo guhindura
Uburyo bwo hejuru bwo guhinduraWi-Fi 6ni 1024-QAM, aho ibimenyetso byo guhindura bitwara 10 bit. Kugirango turusheho kongera igipimo, Wi-Fi 7 izashyiraho 4096-QAM, kugirango ibimenyetso byo guhindura bitwara 12 bits. Muri kodegisi imwe, Wi-Fi 7′s 4096-QAM irashobora kugera ku gipimo cya 20% ugereranije na Wi-Fi 6′s 1024-QAM. (Murakaza neza kwitondera konti yemewe: injeniyeri y'urusobe Aaron)
Menyekanisha uburyo bwinshi-buhuza uburyo bwinshi
Kugirango tugere ku mikoreshereze inoze y’ibikoresho byose biboneka, hakenewe byihutirwa gushyiraho uburyo bushya bwo gucunga imiyoboro, guhuza no gukwirakwiza kuri 2.4 GHz, 5 GHz na 6 GHz. Itsinda ryakazi ryasobanuye ikoranabuhanga rijyanye no guhuza byinshi, cyane cyane harimo ubwubatsi bwa MAC bwo kuzamura imiyoboro myinshi, guhuza imiyoboro myinshi, guhuza imiyoboro myinshi hamwe n’ikoranabuhanga rijyanye nayo.
Shyigikira amakuru menshi, kuzamura imikorere ya MIMO
Muri Wi-Fi 7, umubare wimigezi yatandukanijwe wiyongereye uva kuri 8 ugera kuri 16 muri Wi-Fi 6, mubyukuri birashobora kurenza inshuro ebyiri umuvuduko wo kwanduza umubiri. Gushyigikira amakuru menshi azazana kandi imbaraga zikomeye-zagabanijwe MIMO, bivuze ko amakuru 16 yamakuru ashobora gutangwa atari kumurongo umwe, ariko hamwe nokwinjira inshuro imwe icyarimwe, bivuze ko AP nyinshi zikeneye gufatanya hagati yazo akazi.
Shigikira gahunda ya koperative muri AP nyinshi
Kugeza ubu, murwego rwa 802.11 protocole, mubyukuri nta bufatanye bwinshi hagati ya APs. Imikorere isanzwe ya WLAN nko guhuza byikora no kugendana ubwenge nibintu biranga ibicuruzwa. Intego yubufatanye hagati ya AP nuguhindura gusa guhitamo imiyoboro, guhindura imitwaro hagati ya AP, nibindi, kugirango tugere ku ntego yo gukoresha neza no kugabura neza umutungo wa radio. Gahunda ihuriweho hagati ya AP nyinshi muri Wi-Fi 7, harimo igenamigambi rihuza hagati yutugari mugihe cyagenwe na domaine yumurongo, guhuza ibikorwa hagati yutugari, no gukwirakwiza MIMO, birashobora kugabanya neza kwivanga hagati ya AP, Kunoza cyane imikoreshereze yumutungo wikirere.
?
Hariho uburyo bwinshi bwo guhuza gahunda hagati ya AP nyinshi, harimo C-OFDMA (Guhuza Orthogonal Frequency-Division Multiple Access), CSR (Coordinated Spatial Reuse), CBF (Beamforming Coordinated), na JXT (Kohereza hamwe).
5. Amashusho yo gusaba ya Wi-Fi 7
Ibintu bishya byatangijwe na Wi-Fi 7 bizamura cyane igipimo cyo kohereza amakuru kandi bitange ubukererwe buke, kandi izo nyungu zizafasha cyane mubikorwa bigenda bigaragara, nkibi bikurikira:
- Amashusho
- Video / Inama Ijwi
- Umukino wa Wireless
- Ubufatanye nyabwo
- Igicu / Impapuro
- Urubuga rwa interineti rwibintu
- Immersive AR / VR
