Ibibazo byugarije Wi-Fi 6E?

1. 6GHz ikibazo gikomeye

Ibikoresho byabaguzi hamwe nikoranabuhanga risanzwe rihuza nka Wi-Fi, Bluetooth, na selire bifasha gusa imirongo igera kuri 5.9GHz, bityo ibice nibikoresho byakoreshejwe mugushushanya no gukora byahinduwe neza mumirongo iri munsi ya 6 GHz kugirango ubwihindurize bwibikoresho bigoboka kugeza 7.125 GHz igira ingaruka zikomeye kubuzima bwose bwibicuruzwa kuva mubishushanyo mbonera no kwemezwa kugeza mubikorwa.

2. 1200MHz ultra-rugari passband ikibazo

Umuyoboro mugari wa 1200MHz werekana imbogamizi ku gishushanyo mbonera cya RF imbere kuko ikeneye gutanga imikorere ihamye kumurongo wose wa radiyo kuva hasi kugeza kumuyoboro muremure kandi bisaba imikorere myiza ya PA / LNA yo gukwirakwiza 6 GHz . umurongo. Mubisanzwe, imikorere itangira guteshwa agaciro kumurongo mwinshi wa bande, kandi ibikoresho bigomba guhindurwa no kugeragezwa kumurongo mwinshi kugirango barebe ko bishobora kubyara ingufu ziteganijwe.

3. Ibibazo bibiri cyangwa tri-bande yo gushushanya

Ibikoresho bya Wi-Fi 6E bikunze gukoreshwa nkibikoresho bibiri (5 GHz + 6 GHz) cyangwa (2.4 GHz + 5 GHz + 6 GHz). Kubana kw'imigozi myinshi na MIMO imigezi, ibi byongeye gushira ibisabwa cyane imbere yimbere ya RF mubijyanye no kwishyira hamwe, umwanya, gukwirakwiza ubushyuhe, no gucunga ingufu. Akayunguruzo karasabwa kugirango hamenyekane umurongo ukwiye kugirango wirinde kwivanga mubikoresho. Ibi byongera igishushanyo mbonera no kugenzura bigoye kuko ibizamini byinshi byo kubana / desensitisation bigomba gukorwa kandi imirongo myinshi yumurongo igomba kugeragezwa icyarimwe.

4. Ibyuka bihumanya ikirere bigabanya ibibazo

Kugirango tubane neza mumahoro hamwe na serivise zisanzwe zigendanwa kandi zihamye mugice cya 6GHz, ibikoresho bikorera hanze bigenzurwa na sisitemu ya AFC (Automatic Frequency Coordination).

5. 80MHz na 160MHz ibibazo byumuvuduko mwinshi

Ubugari bwagutse bwumurongo butera imbogamizi kuberako umurongo mwinshi bisobanura kandi abatwara amakuru menshi ya OFDMA bashobora koherezwa (kandi bakakirwa) icyarimwe. SNR kuri buri mutwara yagabanutse, bityo imikorere yohereza transmitter yo hejuru irakenewe kugirango decode igende neza.

Kuringaniza Spectral ni igipimo cyo gukwirakwiza imbaraga zinyuranye mumashanyarazi yose yikimenyetso cya OFDMA kandi biranagoye cyane kumiyoboro yagutse. Kugoreka bibaho mugihe abatwara imirongo itandukanye bahujwe cyangwa bongerewe nibintu bitandukanye, kandi uko intera nini yagutse, niko bishoboka cyane ko bagaragaza ubu bwoko bwo kugoreka.

6. 1024-QAM modulisiyo yo hejuru ifite ibyangombwa bisabwa kuri EVM

Ukoresheje gahunda-yohejuru ya QAM modulasiyo, intera iri hagati yinyenyeri ziyegereje, igikoresho kiba cyunvikana kubitagenda neza, kandi sisitemu isaba SNR yo hejuru kugirango yerekane neza. Igipimo cya 802.11ax gisaba EVM ya 1024QAM kuba <−35 dB, mugihe 256 EVM ya QAM iri munsi ya −32 dB.

7. OFDMA isaba guhuza neza

OFDMA isaba ko ibikoresho byose bigira uruhare mugukwirakwiza bihuzwa. Ukuri kwigihe, inshuro, hamwe nimbaraga zoguhuza hagati ya AP na sitasiyo zabakiriya bigena ubushobozi bwurusobe muri rusange.

Mugihe abakoresha benshi basangiye ibiboneka, kwivanga kumukinnyi umwe mubi bishobora gutesha agaciro imikorere yabandi bakoresha bose. Sitasiyo y'abakiriya yitabira igomba kohereza icyarimwe muri 400 ns ya buriwese, guhuza imirongo (± 350 Hz), no kohereza imbaraga muri ± 3 dB. Ibi bisobanuro bisaba urwego rwukuri rutigeze ruteganijwe kubikoresho bya Wi-Fi byashize kandi bisaba kugenzurwa neza.
