1. 6GHz kev sib tw siab zaus
Cov neeg siv khoom siv nrog cov thev naus laus zis sib txuas xws li Wi-Fi, Bluetooth, thiab xov tooj ntawm tes tsuas yog txhawb nqa zaus mus txog 5.9GHz, yog li cov khoom siv thiab cov khoom siv los tsim thiab tsim muaj keeb kwm tau ua kom zoo dua rau zaus qis dua 6 GHz rau kev hloov pauv ntawm cov cuab yeej txhawb nqa mus txog. 7.125 GHz muaj qhov cuam tshuam loj rau tag nrho cov khoom lag luam lub neej los ntawm cov khoom tsim thiab kev siv tau los ntawm kev tsim khoom.
2. 1200MHz ultra-wide passband kev sib tw
Qhov ntau zaus ntawm 1200MHz nthuav tawm qhov kev sib tw rau kev tsim ntawm RF pem hauv ntej-kawg raws li nws xav tau los muab kev ua tau zoo sib xws thoob plaws tag nrho cov zaus spectrum los ntawm qhov qis tshaj mus rau qhov siab tshaj channel thiab xav tau PA / LNA kev ua tau zoo rau npog 6 GHz ntau yam. . linearity. Feem ntau, kev ua tau zoo pib degrade ntawm lub siab-zaus ntug ntawm cov qhab, thiab cov khoom siv yuav tsum tau ntsuas thiab ntsuas rau qhov siab tshaj plaws kom ntseeg tau tias lawv tuaj yeem tsim cov qib siab zog.
3. Dual lossis tri-band tsim kev sib tw
Wi-Fi 6E cov khoom siv feem ntau yog siv los ua dual-band (5 GHz + 6 GHz) lossis (2.4 GHz + 5 GHz + 6 GHz) cov khoom siv. Rau kev sib koom ua ke ntawm ntau pawg thiab MIMO ntws, qhov no dua qhov kev xav tau siab ntawm RF pem hauv ntej-kawg ntawm kev sib koom ua ke, qhov chaw, cua sov dissipation, thiab kev tswj fais fab. Kev lim dej yuav tsum tau ua kom muaj kev sib cais band kom tsis txhob cuam tshuam hauv lub cuab yeej. Qhov no ua rau muaj kev tsim thiab kev txheeb xyuas qhov nyuaj vim tias ntau qhov kev sib koom ua ke / desensitization xeem yuav tsum tau ua thiab ntau zaus bands yuav tsum tau sim ib txhij.
4. Kev txwv tsis pub muaj kev sib tw
Txhawm rau kom muaj kev thaj yeeb nyab xeeb nrog cov xov tooj uas twb muaj lawm thiab cov kev pabcuam ruaj khov hauv 6GHz band, cov cuab yeej ua haujlwm sab nraum zoov yuav raug tswj hwm ntawm AFC (Automatic Frequency Coordination) system.
5. 80MHz thiab 160MHz kev sib tw siab bandwidth
Cov kab dav dav dav tsim cov kev sib tw tsim vim tias ntau bandwidth kuj txhais tau tias ntau OFDMA cov ntaub ntawv xa tuaj yeem xa mus (thiab tau txais) ib txhij. SNR ib tus neeg nqa khoom raug txo qis, yog li kev hloov pauv hloov pauv siab dua yuav tsum tau ua kom muaj txiaj ntsig zoo.
Spectral flatness yog ib qho kev ntsuas ntawm kev faib hluav taws xob hloov pauv thoob plaws txhua lub subcarriers ntawm OFDMA teeb liab thiab tseem nyuaj rau cov kab dav dav. Distortion tshwm sim thaum cov neeg nqa khoom ntawm cov zaus sib txawv yog attenuated los yog amplified los ntawm ntau yam sib txawv, thiab qhov loj dua qhov ntau zaus, lawv yuav pom qhov txawv ntawm hom kev sib txawv no.
6. 1024-QAM high-order modulation muaj kev xav tau siab dua ntawm EVM
Siv cov kev txiav txim siab dua QAM hloov kho, qhov kev ncua deb ntawm cov ntsiab lus ntawm lub hnub qub yog ze dua, cov cuab yeej ua rau muaj kev cuam tshuam ntau dua, thiab lub kaw lus xav tau SNR siab dua los txiav txim kom raug. Tus qauv 802.11ax xav kom EVM ntawm 1024QAM yuav < −35 dB, thaum 256 EVM ntawm QAM tsawg dua −32 dB.
7. OFDMA yuav tsum tau synchronization ntau meej
OFDMA xav kom txhua yam khoom siv koom nrog hauv kev sib kis yuav tsum tau synchronized. Qhov tseeb ntawm lub sij hawm, zaus, thiab lub zog synchronization ntawm APs thiab cov chaw nres tsheb cov neeg siv khoom txiav txim siab tag nrho cov peev txheej hauv lub network.
Thaum ntau tus neeg siv faib cov spectrum muaj, cuam tshuam los ntawm ib tus neeg ua phem phem tuaj yeem ua rau kev ua haujlwm hauv network rau tag nrho lwm tus neeg siv. Cov chaw koom nrog cov neeg siv khoom yuav tsum xa ib txhij hauv 400 ns ntawm ib leeg, zaus ua raws (± 350 Hz), thiab xa hluav taws xob hauv ± 3 dB. Cov kev qhia tshwj xeeb no xav tau qib ntawm qhov tseeb tsis tau xav tau los ntawm Wi-Fi yav dhau los thiab yuav tsum tau ua tib zoo xyuas.
