URohde & Schwarz (R&S) wethule ubufakazi bomqondo wohlelo lokudlulisa idatha olungenantambo lwe-6G olusekelwe ezixhumanisini zokuxhumana ze-photonic terahertz e-European Microwave Week (EuMW 2024) eParis, olusiza ekuthuthukiseni umngcele wobuchwepheshe obungenantambo besizukulwane esilandelayo. Uhlelo lwe-terahertz oluguquguqukayo oluzinzile kakhulu olwakhiwe kuphrojekthi ye-6G-ADLANTIK lusekelwe kubuchwepheshe be-frequency comb, kanye nama-frequency okuthwala angaphezu kuka-500GHz.
Endleleni eya ku-6G, kubalulekile ukudala imithombo yokudlulisa i-terahertz enikeza isignali esezingeni eliphezulu futhi engamboza ububanzi obukhulu kakhulu bemvamisa. Ukuhlanganisa ubuchwepheshe be-optical nobuchwepheshe be-elekthronikhi kungenye yezinketho zokufeza lo mgomo esikhathini esizayo. Engqungqutheleni ye-EuMW 2024 eParis, i-R&S ikhombisa umnikelo wayo ocwaningweni lwe-terahertz olusezingeni eliphezulu kuphrojekthi ye-6G-ADLANTIK. Le phrojekthi igxile ekuthuthukisweni kwezingxenye zemvamisa ye-terahertz ngokusekelwe ekuhlanganisweni kwama-photon nama-electron. Lezi zingxenye ze-terahertz ezingakathuthukiswa zingasetshenziswa ekulinganisweni okusha kanye nokudluliswa kwedatha okusheshayo. Lezi zingxenye zingasetshenziswa hhayi kuphela ekuxhumaneni kwe-6G, kodwa futhi nasekuzweleni nasekuthatheni izithombe.
Iphrojekthi ye-6G-ADLANTIK ixhaswe yi-German Federal Ministry of Education and Research (BMBF) futhi iqondiswa yi-R&S. Abalingani bahlanganisa i-TOPTICA Photonics AG, i-Fraunhofer-Institut HHI, i-Microwave Photonics GmbH, i-Technical University of Berlin kanye ne-Spinner GmbH.
Uhlelo lwe-terahertz oluguquguqukayo oluzinzile kakhulu lwe-6G olusekelwe kubuchwepheshe be-photon
Ubufakazi bomqondo bubonisa uhlelo lwe-terahertz oluzinzile kakhulu, olulungisekayo lokudluliswa kwedatha engenantambo ye-6G ngokusekelwe kubaxubi be-terahertz be-photonic abakhiqiza izimpawu ze-terahertz ngokusekelwe kubuchwepheshe be-frequency comb. Kulesi simiso, i-photodiode iguqula ngempumelelo izimpawu zokushaya kwe-optical ezikhiqizwa ama-laser anama-frequency optical ahlukene kancane abe izimpawu zikagesi ngenqubo yokuxuba i-photon. Isakhiwo se-antenna esizungeze i-photoelectric mixer siguqula i-photocurrent ejikelezayo ibe amagagasi e-terahertz. Isignali ephumayo ingaguqulwa futhi ihlukaniswe ukuxhumana okungenantambo kwe-6G futhi ingalungiswa kalula ebangeni elibanzi lemvamisa. Uhlelo lungandiswa futhi ekulinganisweni kwezingxenye kusetshenziswa izimpawu ze-terahertz ezitholwe ngokuhambisanayo. Ukulingiswa kanye nokwakhiwa kwezakhiwo ze-terahertz waveguide kanye nokuthuthukiswa kwama-oscillator e-photonic reference oscillators aphansi kakhulu nakho kuphakathi kwezindawo zokusebenza zephrojekthi.
Umsindo wesigaba ophansi kakhulu wesistimu ubangelwa yi-frequency comb-locked optical frequency synthesizer (OFS) enjinini ye-laser ye-TOPTICA. Izinsimbi ze-R&S eziphezulu ziyingxenye ebalulekile yalolu hlelo: Ijenereyitha yesignali ye-vector ye-R&S SFI100A wideband IF idala isignali ye-baseband ye-optical modulator enesilinganiso sokusampula esingu-16GS/s. Ijenereyitha yesignali ye-R&S SMA100B RF kanye ne-microwave ikhiqiza isignali yewashi eliqinile lezinhlelo ze-TOPTICA OFS. I-oscilloscope ye-R&S RTP isampula isignali ye-baseband ngemuva kwe-photoconductive continuous wave (cw) terahertz receiver (Rx) ngesilinganiso sokusampula esingu-40 GS/s ukuze kuqhutshekwe kucutshungulwe futhi kususwe isignali yemvamisa yenkampani engu-300 GHz.
Izidingo zebhendi yemvamisa ye-6G kanye neyesikhathi esizayo
I-6G izoletha izimo ezintsha zohlelo lokusebenza embonini, ubuchwepheshe bezokwelapha kanye nokuphila kwansuku zonke. Izinhlelo zokusebenza ezifana ne-metacomes kanye ne-Extended Reality (XR) zizobeka izidingo ezintsha kumazinga okubambezeleka kanye nokudluliswa kwedatha angenakufezwa yizinhlelo zokuxhumana zamanje. Ngenkathi i-International Telecommunication Union's World Radio Conference 2023 (WRC23) ithole amabhendi amasha ku-FR3 spectrum (7.125-24 GHz) ukuze kwenziwe ucwaningo olwengeziwe lwamanethiwekhi okuqala e-6G ezohwebo azoqalwa ngo-2030, Kodwa ukuze kufezwe amandla aphelele e-virtual reality (VR), augmented reality (AR) kanye ne-mixed reality (MR), ibhendi ye-Asia-Pacific Hertz efinyelela ku-300 GHz nayo izoba yinto ebalulekile.
