Izinselelo ezibhekene ne-Wi-Fi 6e?

1. I-6GHzz Fent Frequency Challenge

Amadivayisi wabathengi ngobuchwepheshe obujwayelekile bokuxhuma afana ne-Wi-Fi, i-Bluetooth, kanye namakhalekhukhwini okusekelwa okufika ku-5.9GHz, ngakho-ke izingxenye namadivayisi asetshenziselwa ukuklama futhi akhiqize ngokomlando ngokusemthethweni okungu-6 GHZ ngokutholwa kwamathuluzi ukusekela kuze kube I-7.125 i-GHz inomthelela omkhulu kukho konke umkhiqizo wokuphila komkhiqizo kusuka ekuklameni komkhiqizo kanye nokuqinisekiswa ekwakheni.

2. 1200mhz Ultra-Wide PASSPLALNELLANDBAMBA

Ububanzi bamatheksthi abanzi obungu-1200mhz baletha inselelo ekwakhiweni kwe-RF ngaphambili-ukuphela njengoba kudinga ukuhlinzeka ngokusebenza okujwayelekile ku-frequency suplenvest kusuka esiteshini esiphakeme kakhulu futhi kudinga ukusebenza okuhle kwe-PA / LNA . ulayini. Imvamisa, ukusebenza kuqala ukungcolisa umphetho weqembu eliphakeme kakhulu le-band, futhi amadivayisi adinga ukulinganiswa futhi ahlolwe amaza aphezulu kakhulu ukuze aqinisekise ukuthi angakhiqiza amazinga wamandla alindelekile.

3. Izinselelo ezi-Dual noma ze-Tri-band

Amadivayisi we-Wi-Fi 6e ajwayele ukuhanjiswa njenge-dual-band (5 ghz + 6 ghz) noma (2.4 ghz + 5hz + 5hz + 5 GHz). Ngokuhlaziya kwe-multi-band kanye nemifudlana ye-mimo, lokhu kuphinde kube nezidingo eziphakeme ekupheleni kwe-RF ngaphambili ngokuya ngokuhlanganiswa, isikhala, ukuncipha kokushisa, kanye nokuphathwa kwamandla. Ukuhlunga kuyadingeka ukuqinisekisa ukuhlukaniswa kwebhendi okufanelekile ukugwema ukuphazanyiswa ngaphakathi kwedivayisi. Lokhu kukhulisa ukuklama nokubumbana kokuxazulula ngoba ukuhlolwa okwengeziwe / ukuqinisekiswa kwezidingo kudinga ukwenziwa kanye nama-band amaningi amvamisa kudingeka ahlolwe ngasikhathi sinye.

4. Inselelo Yemikhawulo Yemikhawulo

Ukuqinisekisa ukuhlangana okunokuthula ngezinsizakalo ezikhona zeselula nezihleliwe ebhendini le-6GHz, imishini yokusebenza ngaphandle kuncike ekuphathweni kwe-AFC (i-othomathotichault frequency cordy).

I-5. 80MHZ kanye nezinselelo ze-bandwidth eziphakeme ze-160mhz

Ububanzi besiteshi obubanzi bakha izinselelo zokuklama ngoba i-bandwidth engaphezulu futhi isho izithwali zedatha eziningi zingadluliswa (futhi zitholakele) ngasikhathi sinye. I-SNR ngayinye yenethiwekhi incishisiwe, ngakho-ke ukusebenza okuphezulu kokuguqulwa kwe-Transmitter kuyadingeka ekuhlolweni okuphumelelayo.

I-Spectral Flatness iyisilinganiso sokusatshalaliswa kokuhluka kwamandla kuwo wonke ama-subcarriers we-Ofdma Signal futhi futhi inselele ngokwengeziwe eziteshini ezibanzi. Ukuhlanekezela kwenzeka lapho abathwali bamatheksthi ahlukene betholwa noma bakhuliswe ngezinto ezahlukahlukene, futhi kukhudlwana ibanga lokuvama okuvamile, kulapho kufanele babonise lolu hlobo lokuhlanekezela.

6. Ukushintshwa kwe-1024-QAM-QAM okuphezulu kwe-Order kunezidingo eziphakeme ku-EVM

Kusetshenziswa ukuguquguquka kwe-Order QAM ephakeme, ibanga phakathi kwamaphoyinti we-Constellation liseduze, idivaysi iba nozwela ngokwengeziwe ekulimazekeni, futhi uhlelo ludinga ukuthi i-SNR ephakeme ibe yidelela kahle. I-802.11ax ejwayelekile idinga i-EVM ka-1024qam ukuba ibe <-35 db, ngenkathi u-256 i-EVM yeQam ingaphansi kwe--32 dB.

7. I-OFMA idinga ukuvumelanisa okuqondile

I-OFMA idinga ukuthi wonke amadivaysi athintekayo ekudluliseleni avumelaniswe. Ukunemba kwesikhathi, imvamisa, kanye nokuvumelanisa kwamandla phakathi kwama-APS neziteshi zamakhasimende kunquma umthamo wenethiwekhi jikelele.

Lapho abasebenzisi abaningi babelana nge-spectrum etholakalayo, ukuphazamiseka kusuka kumlingisi oyedwa omubi kungadalula ukusebenza kwenethiwekhi kubo bonke abanye abasebenzisi. Iziteshi zamakhasimende ezibambe iqhaza kufanele zidlulise ngasikhathi sinye phakathi kwama-400 ns zomunye nomunye, imvamisa eqondanisiwe (± 350 Hz), bese udlulisa amandla ngaphakathi ku- ± 3 dB. Lokhu kucaciswa kudinga izinga lokunemba elingalindelwe kumadivayisi we-Wi-Fi adlule futhi adinga ukuqinisekiswa ngokucophelela.
