Matambudziko akatarisana neWi-Fi 6E?

1. 6GHz high frequency dambudziko

Zvishandiso zvevatengi zvine hunyanzvi hwekubatanidza matekinoroji seWi-Fi, Bluetooth, uye nharembozha zvinongotsigira mafambiro anosvika ku5.9GHz, saka zvikamu nemidziyo yaishandiswa kugadzira nekugadzira yakagara yakagadziridzwa kuitira ma frequency ari pasi pe6 GHz yeKushanduka kwezvishandiso zvekutsigira kusvika. 7.125 GHz ine simba rakakosha pahupenyu hwese hwechigadzirwa kubva pakugadzirwa kwechigadzirwa uye kusimbiswa kusvika pakugadzira.

2. 1200MHz Ultra-wide passband dambudziko

Iyo yakafara frequency renji ye1200MHz inopa dambudziko kune dhizaini yeRF yekumberi-yekupedzisira sezvo ichida kupa kunoenderana kuita kwese kwese frequency spectrum kubva kune yakaderera kusvika kune yepamusoro chiteshi uye inoda yakanaka PA/LNA kuita kwekuvhara 6 GHz renji. . mutsara. Kazhinji, kuita kunotanga kudzikira pakakwirira-frequency kumucheto kwebhendi, uye zvishandiso zvinofanirwa kuverengerwa uye kuyedzwa kune epamusoro mafrequency kuti ive nechokwadi chekuti anogona kuburitsa mazinga anotarisirwa emagetsi.

3. Dual kana tri-bhendi dhizaini matambudziko

Wi-Fi 6E zvishandiso zvinonyanya kuisirwa sembiri-bhendi (5 GHz + 6 GHz) kana (2.4 GHz + 5 GHz + 6 GHz) zvishandiso. Nekugarisana kweakawanda-bhendi uye MIMO hova, izvi zvakare zvinoisa zvakakwirira zvinodiwa paRF kumberi-kumagumo maererano nekubatanidza, nzvimbo, kupisa kupisa, uye kutonga kwesimba. Kusefa kunodiwa kuti uve nechokwadi chekuzviparadzanisa nebhendi kudzivirira kukanganisa mukati memudziyo. Izvi zvinowedzera dhizaini uye kuomarara kwekuona nekuti kwakawanda kugarisana/desensitization bvunzo dzinoda kuitwa uye akawanda ma frequency mabhendi anoda kuedzwa panguva imwe chete.

4. Emissions muganhu dambudziko

Kuve nechokwadi chekugarisana murunyararo nemasevhisi aripo uye akagadziriswa mubhendi re6GHz, midziyo inoshanda kunze inotongwa neiyo AFC (Automatic Frequency Coordination) system.

5. 80MHz uye 160MHz yakakwirira bandwidth matambudziko

Yakafara chiteshi upamhi inogadzira matambudziko ekugadzira nekuti yakawanda bandwidth zvakare inoreva yakawanda yeOFDMA data vatakuri vanogona kutapurirana (uye kugamuchirwa) panguva imwe chete. Iyo SNR pamutakuri yakaderedzwa, saka yakakwira transmitter modulation performance inodiwa kuti ibudirire decoding.

Spectral flatness chiyero chekugoverwa kwekusiyana kwesimba kune ese madiki eiyo OFDMA chiratidzo uye zvakare yakanyanya kunetsa kune yakafara nzira. Kukanganisa kunoitika kana vatakuri veakasiyana mafrequency vakaderedzwa kana kukwidziridzwa nezvikonzero zvakasiyana, uye yakakura iyo frequency renji, ivo vanonyanya kuratidza rudzi urwu rwekukanganisa.

6. 1024-QAM high-order modulation ine zvinodiwa zvepamusoro paEVM

Uchishandisa yakakwirira-odha QAM modulation, chinhambwe chiri pakati pemapoka enyeredzi chiri padyo, chishandiso chinova chakanyanya kutarisisa kukanganisa, uye sisitimu inoda yakakwira SNR kuti idzore nemazvo. Iyo 802.11ax chiyero inoda kuti EVM ye1024QAM ive <-35 dB, ukuwo 256 Iyo EVM yeQAM iri pasi pe −32 dB.

7. OFDMA inoda kunyatsoenderana

OFDMA inoda kuti zvishandiso zvese zvinobatanidzwa mukufambisira zvibatanidzwe. Iko kurongeka kwenguva, frequency, uye simba kuwiriranisa pakati peAPs uye vatengi zviteshi zvinotarisa huwandu hwese network.

Kana vashandisi vakawanda vakagovana spectrum iripo, kuvhiringidza kubva kumutambi mumwe chete akaipa kunogona kukanganisa mashandiro etiweki kune vamwe vese vashandisi. Zviteshi zvevatengi zvinotora chikamu zvinofanirwa kufambisa panguva imwe chete mukati me400 ns yeimwe neimwe, frequency yakaenderana (± 350 Hz), uye kufambisa simba mukati me ± 3 dB. Aya maratidziro anoda nhanho yechokwadi isingambotarisirwe kubva kune yakapfuura Wi-Fi zvishandiso uye inoda kunyatso tariswa.
