Izinselele ezibhekene ne-Wi-Fi 6E?

1. 6GHz inselelo yefrikhwensi ephezulu

Amadivayisi ekhasimende anobuchwepheshe bokuxhumana obuvamile njenge-Wi-Fi, i-Bluetooth, namaselula asekela kuphela amafrikhwensi afika ku-5.9GHz, ngakho izingxenye namadivayisi asetshenziselwa ukuklama nokukhiqiza aye athuthukiswa ngokomlando ukuze abe amafrikhwensi angaphansi kuka-6 GHz ukuze uthole Ukuvela kwamathuluzi okusekela kuze kufike ku-5.9GHz. I-7.125 GHz inomthelela omkhulu kuwo wonke umjikelezo wempilo womkhiqizo kusukela ekwakhiweni komkhiqizo nokuqinisekiswa kuye ekukhiqizeni.

2. 1200MHz inselele yebhendi yokudlula ebanzi kakhulu

Ibanga elibanzi lefrikhwensi lika-1200MHz liletha inselele ekwakhiweni kwe-RF front-end njengoba idinga ukunikeza ukusebenza okungaguquguquki kuwo wonke ama-frequency spectrum kusukela kwephansi kakhulu kuye kwephezulu kakhulu futhi idinga ukusebenza okuhle kwe-PA/LNA ukumboza uhla lwe-6 GHz. . umugqa. Ngokuvamile, ukusebenza kuqala ukwehla emaphethelweni efrikhwensi ephezulu yebhendi, futhi amadivayisi adinga ukulinganiswa futhi ahlolwe ukuze afike kumaza aphakeme kakhulu ukuze kuqinisekiswe ukuthi angakhiqiza amaleveli wamandla alindelekile.

3. Izinselelo zedizayini ezikabili noma ezintathu

Amadivayisi e-Wi-Fi 6E asetshenziswa kakhulu njengama-dual-band (5 GHz + 6 GHz) noma (2.4 GHz + 5 GHz + 6 GHz) amadivayisi. Ngokuhlalisana kokusakazwa kwama-multi-band kanye ne-MIMO, lokhu futhi kubeka izimfuno eziphezulu ku-RF front-end mayelana nokuhlanganiswa, isikhala, ukuchithwa kokushisa, nokuphathwa kwamandla. Ukuhlunga kuyadingeka ukuze kuqinisekiswe ukuhlukaniswa kwebhendi okufanele ukuze kugwenywe ukuphazamiseka ngaphakathi kwedivayisi. Lokhu kukhulisa ubunkimbinkimbi bomklamo nokuqinisekisa ngoba ukuhlolwa kokuhlalisana/ukungazweli okwengeziwe kudingeka kwenziwe futhi namabhendi efrikhwensi amaningi adinga ukuhlolwa ngesikhathi esisodwa.

4. Inselele yomkhawulo wokukhishwa kwekhabhoni

Ukuqinisekisa ukuphilisana ngokuthula nezinsiza ezikhona zamaselula nezigxilile kubhendi ye-6GHz, okokusebenza okusebenza ngaphandle kungaphansi kokulawulwa kwesistimu ye-AFC (Automatic Frequency Coordination).

5. 80MHz kanye nezinselele zomkhawulokudonsa ongu-160MHz eziphezulu

Ububanzi beziteshi ezibanzi budala izinselele zokuklama ngoba umkhawulokudonsa owengeziwe ubuye usho ukuthi abathwali bedatha abaningi be-OFDMA bangadluliswa (futhi bamukelwe) ngesikhathi esisodwa. I-SNR ngenkampani yenethiwekhi ngayinye incishisiwe, ngakho-ke ukusebenza kwe-modulation yesidlulisi esiphezulu kuyadingeka ukuze kukhishwe amakhodi ngempumelelo.

I-Spectral flatness isilinganiso sokusatshalaliswa kokuhlukahluka kwamandla kuzo zonke izinkampani ezingaphansi zesiginali ye-OFDMA futhi kuyinselele enkulu kumashaneli abanzi. Ukuhlanekezela kwenzeka lapho abathwali bamafrikhwensi ahlukene bencishiswa noma bekhuliswa izici ezihlukene, futhi uma likhulu ibanga lefrikhwensi, maningi amathuba okuba babonise lolu hlobo lokuhlanekezela.

6. Ukuguqulwa kwe-oda eliphezulu kwe-1024-QAM kunezidingo eziphakeme ku-EVM

Isebenzisa ukuguquguquka kwe-QAM oku-oda okuphezulu, ibanga eliphakathi kwamaphoyinti ezinkanyezi liseduze, idivayisi iba bucayi kakhulu ekonakaleni, futhi isistimu idinga i-SNR ephezulu ukuze yehlise ngokulungile. Izinga le-802.11ax lidinga i-EVM engu-1024QAM ukuthi ibe < −35 dB, kuyilapho 256 I-EVM ye-QAM ingaphansi kuka-−32 dB.

7. I-OFDMA idinga ukuvumelanisa okunembe kakhudlwana

I-OFDMA idinga ukuthi wonke amadivaysi abandakanyekayo ekudluliselweni avunyelaniswe. Ukunemba kwesikhathi, imvamisa, namandla okuvumelanisa phakathi kwama-AP neziteshi zamaklayenti kunquma umthamo wenethiwekhi iyonke.

Uma abasebenzisi abaningi babelana nge-spectrum etholakalayo, ukuphazamiseka okuvela kumlingisi oyedwa omubi kungehlisa isithunzi ukusebenza kwenethiwekhi kubo bonke abanye abasebenzisi. Iziteshi zamaklayenti abambe iqhaza kufanele zidlulise ngesikhathi esisodwa phakathi kwama-400 ns enye nenye, imvamisa eqondaniswe (± 350 Hz), futhi idlulise amandla ngaphakathi ±3 dB. Lezi zicaciso zidinga ileveli yokunemba engakaze ilindelwe kumadivayisi e-Wi-Fi edlule futhi idinga ukuqinisekiswa ngokucophelela.
