Imingeni ejongene ne-Wi-Fi 6E?

1. 6GHz umceli mngeni ohamba rhoqo

Izixhobo zabathengi ezinonxibelelwano oluqhelekileyo lwetekhnoloji efana ne-Wi-Fi, iBluetooth, kunye neselfowuni zixhasa kuphela amaza ukuya kuthi ga kwi-5.9GHz, ngoko ke izixhobo kunye nezixhobo ezisetyenziselwa ukuyila nokuvelisa bezifudula ziphuculwa ukuba zibe ngaphantsi kwe-6 GHz ukuvela kwezixhobo zokuxhasa ukuya kuthi ga. I-7.125 GHz inempembelelo ebalulekileyo kubomi bemveliso iphela ukusuka kuyilo lwemveliso kunye nokuqinisekiswa ukuya kwimveliso.

2. 1200MHz umngeni wokupasa obanzi kakhulu

Uluhlu olubanzi lwamaza e-1200MHz lunika umngeni kuyilo lwe-RF yangaphambili-isiphelo njengoko ifuna ukubonelela ukusebenza okungaguquguqukiyo kuwo wonke amaza osasazo ukusuka kwelona lisezantsi ukuya kwelona jelo liphezulu kwaye ifuna ukusebenza kakuhle kwe-PA/LNA ukugubungela uluhlu lwe-6 GHz. . umgca. Ngokuqhelekileyo, ukusebenza kuqala ukuthotywa kwinqanaba eliphezulu le-band, kwaye izixhobo kufuneka zilinganiswe kwaye zivavanywe kwii-frequencies eziphezulu zokuqinisekisa ukuba zinokuvelisa amanqanaba ombane alindelekileyo.

3. Imingeni yoyilo kabini okanye ezintathu-band

Izixhobo ze-Wi-Fi 6E zidla ngokusetyenziswa njenge-dual-band (5 GHz + 6 GHz) okanye (2.4 GHz + 5 GHz + 6 GHz) izixhobo. Ukuhlalisana kwee-multi-band kunye ne-MIMO streams, oku kuphinda kubeke iimfuno eziphezulu kwi-RF front-end ngokudibanisa, indawo, ukutshatyalaliswa kobushushu, kunye nolawulo lwamandla. Ukuhluza kuyafuneka ukuze kuqinisekiswe ukwahlukaniswa kwebhendi okufanelekileyo ukuphepha ukuphazamiseka ngaphakathi kwesixhobo. Oku kwandisa uyilo kunye nobunzima bokuqinisekisa kuba uvavanyo lokuhlalisana / ukungavani kufuneka lwenziwe kwaye iibhendi zamaza amaninzi kufuneka zivavanywe ngaxeshanye.

4. Umceli mngeni wokunciphisa izinto ezikhutshwayo

Ukuqinisekisa ukuhlalisana ngoxolo kunye neenkonzo ezikhoyo eziphathwayo kunye nezisisigxina kwibhendi ye-6GHz, izixhobo ezisebenza ngaphandle ziphantsi kolawulo lwe-AFC (i-Automatic Frequency Coordination) inkqubo.

5. 80MHz kunye 160MHz imingeni bandwidth ephezulu

Ububanzi betshaneli ebanzi budala imingeni yoyilo kuba i-bandwidth engaphezulu ikwathetha ukuba abathwali bedatha be-OFDMA abaninzi banokusasazwa (kwaye bamkelwe) ngaxeshanye. I-SNR ngomphathi ngamnye iyancitshiswa, ngoko ke ukusebenza kwemodyuli ephezulu yokuhambisa iyafuneka ukuze kubhalwe ngempumelelo.

I-Spectral flatness ngumlinganiselo wokusasazwa kokwahluka kwamandla kuzo zonke ii-subcarriers zesignali ye-OFDMA kwaye ikwangumceli mngeni kumajelo abanzi. Ukuphazamiseka kwenzeka xa abathwali beefrikhwensi ezahlukeneyo bencitshiswa okanye benyuswa zizinto ezahlukeneyo, kwaye ubukhulu boluhlu lwamaza, kokukhona banokubonisa olu hlobo lokuphazamiseka.

6. I-1024-QAM yokumodareyitha ephezulu ineemfuno eziphezulu kwi-EVM

Ukusebenzisa ukumodareyitha kwe-QAM ephezulu, umgama phakathi kwamanqaku eenkwenkwezi usondele, isixhobo siba buthathaka ngakumbi kumonakalo, kwaye inkqubo ifuna i-SNR ephezulu ukudiliza ngokuchanekileyo. Umgangatho we-802.11ax ufuna i-EVM ye-1024QAM ibe <-35 dB, ngelixa i-256 I-EVM ye-QAM ingaphantsi kwe-−32 dB.

7. I-OFDMA ifuna ungqamaniso oluchane ngakumbi

I-OFDMA ifuna ukuba zonke izixhobo ezibandakanyekayo kuthumelo zilungelelaniswe. Ukuchaneka kwexesha, ukuphindaphinda, kunye nolungelelwaniso lwamandla phakathi kwe-APs kunye nezikhululo zabathengi zimisela umthamo wenethiwekhi ngokubanzi.

Xa abasebenzisi abaninzi babelana nge-spectrum ekhoyo, ukuphazamiseka kumdlali omnye ombi kunokwehlisa ukusebenza kwenethiwekhi kubo bonke abanye abasebenzisi. Izikhululo zabaxumi ezithatha inxaxheba kufuneka zisasaze ngaxeshanye ngaphakathi kwe-400 ns enye kwenye, i-frequency ehambelanayo (± 350 Hz), kwaye idlulise amandla ngaphakathi kwe-±3 dB. Ezi nkcukacha zifuna umgangatho wokuchaneka ongazange ulindelwe kwizixhobo ezidlulileyo ze-Wi-Fi kwaye zifuna ukuqinisekiswa ngononophelo.
