U-Rohde & Schwarz (R&S) wethule ubufakazi bomqondo wesistimu yokudlulisa idatha engenantambo ye-6G esekelwe kuzixhumanisi zokuxhumana ze-photonic terahertz e-European Microwave Week (EuMW 2024) e-Paris, esiza ukuthuthukisa umngcele wesizukulwane esilandelayo sobuchwepheshe obungenawaya. Isistimu ye-terahertz ekwazi ukuzinza kakhulu ethuthukisiwe ethuthukiswe kuphrojekthi ye-6G-ADLANTIK isekelwe kubuchwepheshe bokukama kwamafrikhwensi, namaza okuphatha angaphezulu kakhulu kuka-500GHz.
Emgwaqeni oya ku-6G, kubalulekile ukudala imithombo yokudlulisa ye-terahertz ehlinzeka ngesignali yekhwalithi ephezulu futhi engamboza ububanzi obubanzi kakhulu obunokwenzeka. Ukuhlanganisa ubuchwepheshe be-optical nobuchwepheshe be-elekthronikhi kungenye yezinketho zokufeza lo mgomo esikhathini esizayo. Engqungqutheleni ye-EuMW 2024 e-Paris, i-R&S ikhombisa umnikelo wayo ocwaningweni olusezingeni eliphezulu lwe-terahertz kuphrojekthi ye-6G-ADLANTIK. Le phrojekthi igxile ekuthuthukisweni kwezingxenye zebanga lemvamisa ye-terahertz ngokusekelwe ekuhlanganisweni kwama-photons nama-electron. Lezi zingxenye ze-terahertz ezisazothuthukiswa zingasetshenziselwa ukulinganisa okusha kanye nokudluliswa kwedatha okusheshayo. Lezi zingxenye zingasetshenziselwa ukuxhumana kwe-6G kuphela, kodwa futhi nokuzwa nokucabanga.
Iphrojekthi ye-6G-ADLANTIK ixhaswe yi-Federal Federal Ministry of Education and Research (BMBF) futhi ihlanganiswe yi-R&S. Ozakwethu bahlanganisa i-TOPTICA Photonics AG, i-Fraunhofer-Institut HHI, i-Microwave Photonics GmbH, i-Technical University of Berlin kanye ne-Spinner GmbH.
Isistimu ye-terahertz ekwazi ukuzinza ye-6G esekelwe kubuchwepheshe be-photon
Ubufakazi bomqondo bubonisa uhlelo lwe-terahertz oluzinzile kakhulu, oluguqulekayo lokudluliswa kwedatha okungenantambo kwe-6G okusekelwe kuzixube ze-terahertz ze-photonic ezikhiqiza amasignali e-terahertz asekelwe kubuchwepheshe bekamu lokuvama. Kulolu hlelo, i-photodiode iguqula ngempumelelo amasiginali we-optical beat akhiqizwe ama-laser anamaza ahluke kancane abe amasignali kagesi ngenqubo yokuxutshwa kwe-photon. Isakhiwo se-antenna esizungeze i-photoelectric mixer siguqula i-photocurrent e-oscillating ibe amagagasi e-terahertz. Isignali ewumphumela ingashintshwa futhi yehliswe ekuxhumaneni okungenantambo kwe-6G futhi ingashunwa kalula ebangeni elibanzi lefrikhwensi. Isistimu inganwetshwa futhi kuzilinganiso zengxenye kusetshenziswa amasiginali e-terahertz atholwe ngokuhambisanayo. Ukulingisa nokuklanywa kwezakhiwo ze-terahertz waveguide kanye nokuthuthukiswa kwama-oscillator ereferensi yezithombe zomsindo wesigaba esiphansi kakhulu nakho kuphakathi kwezindawo zokusebenza zephrojekthi.
Umsindo wesigaba esiphansi kakhulu sesistimu ungenxa ye-frequency comb-locked optical frequency synthesizer (OFS) enjini ye-laser ye-TOPTICA. Amathuluzi e-R&S asezingeni eliphezulu ayingxenye ebalulekile yale sistimu: Ijeneretha yesignali yevekhtha ye-R&S SFI100A ebanzi IF idala isignali ye-baseband yemoduli yokubona enesilinganiso sesampula esingu-16GS/s. I-R&S SMA100B RF kanye nejeneretha yesignali ye-microwave ikhiqiza isignali yewashi eliyisithenjwa ezinzile yezinhlelo ze-TOPTICA OFS. I-oscilloscope ye-R&S RTP isampula isiginali ye-baseband engemuva kwesamukeli se-photoconductive continuous wave (cw) terahertz (Rx) ngesilinganiso sesampula esingu-40 GS/s ukuze kuqhutshekwe nokucutshungulwa kanye nokwehliswa kwesignali yefrikhwensi yenkampani yenethiwekhi engu-300 GHz.
I-6G nezidingo zebhendi yesikhathi esizayo
I-6G izoletha izimo ezintsha zokufaka isicelo embonini, ubuchwepheshe bezokwelapha kanye nempilo yansuku zonke. Izinhlelo zokusebenza ezifana ne-metacomes kanye Neqiniso Elinwetshiwe (XR) zizobeka izimfuno ezintsha kumazinga wokubambezeleka nokudluliswa kwedatha angenakuhlangatshezwana nawo amasistimu okuxhumana amanje. Ngenkathi i-International Telecommunication Union's World Radio Conference 2023 (WRC23) ikhombe amabhendi amasha ku-FR3 spectrum (7.125-24 GHz) ukuze kwenziwe ucwaningo olwengeziwe lwamanethiwekhi okuqala e-6G ezohwebo azokwethulwa ngo-2030, Kodwa ukuze kubonakale amandla aphelele eqiniso elingokoqobo (VR), okungokoqobo okuthuthukisiwe (AR-R) kuya ku-30 yeqiniso le-Hertz (AR-Pacific) kanye ne-30 ye-Asia ye-Pacific I-GHz nayo izoba yimfuneko.
