Nge-2030, unxibelelwano lwe-6G lweselula kulindeleke ukuba luvule indlela yezicelo ezintsha ezifana nobukrelekrele bokwenziwa, ubunyani benyani kunye ne-Intanethi yeZinto.Oku kuya kufuna ukusebenza okuphezulu kunomgangatho okhoyo we-5G weselula usebenzisa izisombululo ezintsha ze-hardware.Ngaloo ndlela, kwi-EuMW 2022, i-Fraunhofer IAF iza kubonisa imodyuli yothumelo ye-GaN eyonga amandla ephuhliswe ngokudibeneyo neFraunhofer HHI kuluhlu oluhambelanayo lwe-6G ngaphezulu kwe-70 GHz.Ukusebenza okuphezulu kwale modyuli kungqinwe nguFraunhofer HHI.
Izithuthi ezizimeleyo, i-telemedicine, iifektri ezizenzekelayo - zonke ezi zicelo zexesha elizayo kwezothutho, ukunakekelwa kwezempilo kunye noshishino zixhomekeke kulwazi kunye nobuchwepheshe bonxibelelwano oluhamba ngaphaya kwamandla omgangatho wonxibelelwano lweselula lwesihlanu lwangoku (5G).Ukuqaliswa okulindelweyo kwe-6G yonxibelelwano lwe-mobile kwi-2030 ithembisa ukubonelela ngeenethiwekhi eziyimfuneko ezikhawulezayo kwimiqulu yedatha efunekayo kwixesha elizayo, kunye namazinga edatha ngaphezu kwe-1 Tbps kunye ne-latency ukuya kwi-100 µs.
Ukususela ngo-2019 njengeprojekthi ye-KONFEKT ("i-6G Communication Components").
Abaphandi baye baphuhlisa iimodyuli zothumelo ezisekelwe kwi-gallium nitride (GaN) yamandla e-semiconductor, ethi okokuqala inokusebenzisa uluhlu lwamaza obuninzi malunga ne-80 GHz (E-band) kunye ne-140 GHz (D-band).Imodyuli entsha ye-E-band transmitter, entsebenzo yayo ephezulu iye yavavanywa ngempumelelo nguFraunhofer HHI, iya kunikezelwa kuluntu lweengcali kwiVeki yeMicrowave yaseYurophu (i-EuMW) eMilan, e-Italy, ukusuka ngomhla wama-25 ukuya kowama-30 kuSeptemba wama-2022.
"Ngenxa yeemfuno eziphezulu zokusebenza kunye nokusebenza kakuhle, i-6G idinga iintlobo ezintsha zezixhobo," kuchaza uDkt Michael Mikulla waseFraunhofer IAF, oququzelela iprojekthi ye-KONFEKT.“Iinxalenye zale mihla zodidi oluphezulu zifikelela umda.Oku kusebenza ngokukodwa kwi-teknoloji ye-semiconductor engaphantsi, kunye nokudibanisa kunye nobuchwepheshe be-eriyali.Ukufezekisa iziphumo ezingcono kakhulu ngokubhekiselele kumandla aphumayo, i-bandwidth kunye nokusebenza kakuhle kwamandla, sisebenzisa i-GaN-based monolithic integration Microwave Microwave Circuits (MMIC) yemodyuli yethu ithatha indawo yeesekethe ze-silicon ezisetyenziswayo ngoku. , ukubonelela ngelahleko ephantsi kakhulu kunye nezinto ezihlangeneyo. Ukongeza, siyahamba ukusuka kwindawo ephezulu kunye neepakethe zoyilo ezicwangcisiweyo zokuphuhlisa ilahleko ephantsi yolwakhiwo lwezakhiwo olunemigangatho yamaza kunye neesekethe ezakhelwe ngaphakathi ezinxuseneyo.
I-Fraunhofer HHI ikwabandakanyeka ngokusebenzayo kuvavanyo lwe-3D eprintiweyo ye-waveguides.Iinxalenye ezininzi ziyilwe, zenziwa kwaye zibonakaliswe kusetyenziswa inkqubo ekhethiweyo yokunyibilika kwe-laser (SLM), kubandakanywa izahlulo zamandla, ii-eriyali kunye nesondlo se-eriyali.Inkqubo iphinda ivumele ukuveliswa okukhawulezayo kunye nokungabizi kakhulu kwamacandelo angenakwenziwa kusetyenziswa iindlela zendabuko, ukuvula indlela yokuphuhliswa kobuchwepheshe be-6G.
"Ngalolu tshintsho lwezobuchwepheshe, i-Fraunhofer Institutes IAF kunye ne-HHI ivumela iJamani kunye neYurophu ukuba ithathe inyathelo elibalulekileyo kwixesha elizayo lezonxibelelwano eziphathwayo, ngelixa linye yenza igalelo elibalulekileyo kulawulo lwezobuchwepheshe belizwe," kusho uMikula.
Imodyuli ye-E-band ibonelela nge-1W yamandla aphumayo ukusuka kwi-81 GHz ukuya kwi-86 GHz ngokudibanisa amandla okuhambisa iimodyuli ezine ezahlukeneyo kunye nendibano ye-waveguide yelahleko ephantsi kakhulu.Oku kwenza ukuba ilungele i-broadband point-to-point data links kwimigama emide, isakhono esibalulekileyo se-architecture ye-6G yexesha elizayo.
Iimvavanyo ezahlukeneyo zokuhanjiswa nguFraunhofer HHI zibonise ukusebenza kwamacandelo aphuhliswe ngokudibeneyo: kwiimeko ezahlukeneyo zangaphandle, iimpawu zihambelana nenkcazo yophuhliso lwe-5G yangoku (i-5G-NR Release 16 ye-3GPP GSM standard).Kwi-85 GHz, i-bandwidth yi-400 MHz.
Ngomgca-wokubona, idatha idluliselwe ngempumelelo ukuya kwiimitha ze-600 kwi-64-symbol Quadrature Amplitude Modulation (64-QAM), ukubonelela nge-bandwidth ephezulu ye-6 bps / Hz.Ubungakanani bevector yempazamo yesignali efunyenweyo (EVM) yi -24.43 dB, ngaphantsi komda we-3GPP we-20.92 dB.Ngenxa yokuba umgca wokujonga uvaliwe yimithi kunye nezithuthi ezipakishweyo, idatha emodareyithiweyo ye-16QAM inokuhanjiswa ngempumelelo ukuya kuthi ga kwi-150 yeemitha.Idatha ye-quadrature modulation (i-quadrature phase shift keying, i-QPSK) isenokudluliselwa kwaye ifunyenwe ngempumelelo kwi-2 bps / Hz nangona umgca wokubona phakathi komthumeli kunye nommkeli uvaliwe ngokupheleleyo.Kuzo zonke iimeko, umlinganiselo ophezulu we-signal-to-noise, ngamanye amaxesha ngaphezu kwe-20 dB, uyimfuneko, ngokukodwa ukuqwalasela uluhlu lwamaza, kwaye lunokufezekiswa kuphela ngokunyusa ukusebenza kwamacandelo.
Kwindlela yesibini, imodyuli yothumelo yaphuhliswa kuluhlu olujikelezayo malunga ne-140 GHz, idibanisa amandla aphumayo angaphezu kwe-100 mW kunye nobukhulu be-bandwidth ye-20 GHz.Uvavanyo lwale modyuli lusengaphambili.Zombini iimodyuli zothumelo zizinto ezifanelekileyo zokuphuhlisa nokuvavanya iinkqubo ze-6G zexesha elizayo kuluhlu lwamaza e-terahertz.
