Ngo-2030, ezokuxhumana zeselula ze-6G kulindeleke ukuthi zivule indlela yezinhlelo zokusebenza ezisha njengobuhlakani bokwenziwa, into engekho ngokoqobo kanye ne-inthanethi Yezinto.Lokhu kuzodinga ukusebenza okuphezulu kunezinga leselula le-5G lamanje lisebenzisa izixazululo zehadiwe entsha.Ngakho-ke, ku-EuMW 2022, i-Fraunhofer IAF izokwethula imojuli yesidlulisi se-GaN eyonga amandla ethuthukiswe ngokuhlanganyela no-Fraunhofer HHI ebangeni lefrikhwensi ye-6G engaphezulu kuka-70 GHz.Ukusebenza okuphezulu kwale mojula kuqinisekiswe nguFraunhofer HHI.
Izimoto ezizimelayo, i-telemedicine, izimboni ezizenzakalelayo - zonke lezi zinhlelo zokusebenza zesikhathi esizayo kwezokuthutha, ukunakekelwa kwezempilo kanye nezimboni zithembele kulwazi nobuchwepheshe bokuxhumana obudlula amandla ezinga lezokuxhumana leselula lesizukulwane sesihlanu samanje (5G).Ukwethulwa okulindelekile kokuxhumana kweselula kwe-6G ngo-2030 kuthembisa ukuhlinzeka ngamanethiwekhi anesivinini esiphezulu adingekayo wevolumu yedatha edingekayo esikhathini esizayo, ngamanani edatha angaphezu kwe-1 Tbps kanye nokubambezeleka kufika ku-100 µs.
Kusukela ngo-2019 njengephrojekthi ye-KONFEKT ("Izingxenye Zokuxhumana ze-6G").
Abacwaningi benze amamojula okudlulisela asekelwe ku-gallium nitride (GaN) power semiconductor, okokuqala ngqa engasebenzisa ububanzi befrikhwensi cishe obungu-80 GHz (E-band) kanye no-140 GHz (D-band).Imojula ye-E-band transmitter entsha, ukusebenza kwayo okuphezulu okuhlolwe ngempumelelo yi-Fraunhofer HHI, izokwethulwa emphakathini ochwepheshe e-European Microwave Week (EuMW) eMilan, e-Italy, kusukela zingama-25 kuya zingama-30 kuSepthemba 2022.
"Ngenxa yezidingo eziphezulu zokusebenza nokusebenza kahle, i-6G idinga izinhlobo ezintsha zemishini," kuchaza uDkt. Michael Mikulla waseFraunhofer IAF, oxhumanisa iphrojekthi ye-KONFEKT.“Izingxenye zesimanjemanje sezifinyelela umkhawulo wazo.Lokhu kusebenza ikakhulukazi kubuchwepheshe be-semiconductor obuyisisekelo, kanye nobuchwepheshe bokuhlanganisa kanye ne-antenna.Ukuze sifinyelele imiphumela engcono kakhulu mayelana namandla okukhiphayo, umkhawulokudonsa kanye nokusebenza kahle kwamandla, sisebenzisa i-GaN-based monolithic integration Microwave Microwave Circuits (MMIC) yemojula yethu ithatha indawo yama-silicon circuits asetshenziswa njengamanje.Njenge-bandgap semiconductor ebanzi, i-GaN ingasebenza ngama-voltage aphezulu , ehlinzeka ngokulahlekelwa okuphansi kakhulu kanye nezingxenye ezihlangene.Ngaphezu kwalokho, siyaqhela kumaphakheji aphezu komhlaba kanye namaphakheji edizayini epulaniwe ukuze sithuthukise izakhiwo ezishintshashintshayo ezilahleka kancane ezinamagagasi namasekhethi ahambisanayo akhelwe ngaphakathi.
I-Fraunhofer HHI iphinde ibambe iqhaza ekuhlolweni kwamagagasi e-3D aphrintiwe.Izingxenye ezimbalwa zakhiwe, zakhiqizwa futhi zenziwa izimpawu kusetshenziswa inqubo ye-selective laser melting (SLM), okuhlanganisa izihlukanisi zamandla, izimpondo kanye nezifunzo zezinti.Le nqubo iphinde ivumele ukukhiqizwa okusheshayo nokungabizi kwezingxenye ezingakwazi ukukhiqizwa kusetshenziswa izindlela zendabuko, okuvula indlela yokuthuthukiswa kobuchwepheshe be-6G.
“Ngalezi zinqubo ezintsha zobuchwepheshe, i-Fraunhofer Institutes IAF kanye ne-HHI ivumela iJalimane ne-Europe ukuthi ithathe isinyathelo esibalulekile esibheke esikhathini esizayo sezokuxhumana ngomakhalekhukhwini, kuyilapho ngesikhathi esifanayo yenza umnikelo obalulekile ekubuseni kwezobuchwepheshe kuzwelonke,” kusho uMikula.
Imojula ye-E-band ihlinzeka ngo-1W wamandla omugqa ophumayo ukusuka ku-81 GHz ukuya ku-86 GHz ngokuhlanganisa amandla okudlulisa amamojula amane ahlukene nomhlangano we-waveguide wokulahlekelwa ophansi kakhulu.Lokhu kuyenza ifanelekele izixhumanisi zedatha ye-Broadband point-to-point ebangeni elide, ikhono elibalulekile lezakhiwo ze-6G zesikhathi esizayo.
Ukuhlolwa okuhlukahlukene kokudlulisela okwenziwa yi-Fraunhofer HHI kubonise ukusebenza kwezingxenye ezithuthukiswe ngokuhlanganyela: ezimweni ezihlukahlukene zangaphandle, amasiginali ahambisana nokucaciswa kwamanje kokuthuthukiswa kwe-5G (Ukukhishwa kwe-5G-NR 16 kwezinga le-3GPP GSM).Ku-85 GHz, i-bandwidth ingu-400 MHz.
Ngomugqa wokubona, idatha idluliselwa ngempumelelo kufika kumamitha angu-600 ku-64-symbol Quadrature Amplitude Modulation (64-QAM), ihlinzeka ngokusebenza kahle komkhawulokudonsa okungu-6 bps/Hz.Ubukhulu be-vector yephutha lesignali etholiwe (EVM) yi- -24.43 dB, ngaphansi kakhulu komkhawulo we-3GPP we- -20.92 dB.Ngenxa yokuthi umugqa wokubuka uvinjwe izihlahla nezimoto ezimile, idatha eshintshiwe engu-16QAM ingadluliselwa ngempumelelo kufika kumamitha angu-150.Idatha ye-Quadrature modulation (quadrature phase shift keying, QPSK) isengadluliswa futhi yamukelwe ngempumelelo ngokusebenza kahle okungu-2 bps/Hz ngisho nalapho umugqa wokubona phakathi komthumeli nomamukeli uvinjwe ngokuphelele.Kuzo zonke izimo, isilinganiso esiphezulu sesignali-kuya-kumsindo, ngezinye izikhathi esingaphezu kuka-20 dB, sibalulekile, ikakhulukazi uma kucatshangelwa ububanzi befrikhwensi, futhi singafezwa kuphela ngokwandisa ukusebenza kwezingxenye.
Endleleni yesibili, imojula yokudlulisela yathuthukiswa yebanga lemvamisa elizungeze i-140 GHz, ihlanganisa amandla okukhipha angaphezu kuka-100 mW nomkhawulokudonsa omkhulu wama-20 GHz.Ukuhlolwa kwale mojula kusengaphambili.Womabili amamojula okudlulisela phambili ayizingxenye ezifanele zokuthuthukisa nokuhlola izinhlelo ze-6G zesikhathi esizayo kububanzi bemvamisa ye-terahertz.
Sicela usebenzise leli fomu uma uhlangabezana namaphutha esipelingi, amaphutha, noma ungathanda ukuhambisa isicelo sokuhlela okuqukethwe kwaleli khasi.Ngemibuzo ejwayelekile, sicela usebenzise ifomu lethu lokuxhumana.Ukuze uthole impendulo evamile, sebenzisa isigaba sokuphawula komphakathi esingezansi (landela imithetho).
Impendulo yakho ibaluleke kakhulu kithi.Nokho, ngenxa yobuningi bemiyalezo, asikwazi ukuqinisekisa izimpendulo ngazinye.
Ikheli lakho le-imeyili lisetshenziselwa ukwazisa abamukeli kuphela ukuthi ngubani othumele i-imeyili.Ikheli lakho noma ikheli lomamukeli ngeke lisetshenziselwe enye injongo.Ulwazi olufakile luzovela ku-imeyili yakho futhi ngeke lugcinwe i-Tech Xplore nganoma iyiphi indlela.
Le webhusayithi isebenzisa amakhukhi ukwenza lula ukuzulazula, ukuhlaziya ukusebenzisa kwakho amasevisi ethu, ukuqoqa idatha ukuze wenze izikhangiso zibe ngokwakho, futhi inikeze okuqukethwe okuvela kwabanye abantu.Ngokusebenzisa iwebhusayithi yethu, uyavuma ukuthi uyifundile futhi wayiqonda Inqubomgomo yethu Yobumfihlo kanye Nemigomo Yokusebenzisa.
