I-Rohde ne-Schwarz (R & S) yethula ubufakazi bohlelo lokuhambisa idatha olungenantambo olususelwa ku-PhotoRic Terahettz Communication Links e-European Microwave Isonto lase-European (EumW 2024) eParis, kusiza ukuqhubekisela phambili umngcele wobuchwepheshe obuseduze ne-wireless. Uhlelo lwe-terartz oluzinzile oluqinile lwe-terartz athuthukiswe kuphrojekthi ye-6G-AdLantik isuselwa kubuchwepheshe be-Frequency Work, ngamafrikhwensi ethwala ngaphezu kwe-500ghtz.
Emgwaqweni oya ku-6G, kubalulekile ukudala imithombo yokuhambisa ye-terahertz enikezela ngesiginali esezingeni eliphakeme futhi ingamboza uhla lwemvamisa olubanzi kakhulu. Ukuhlanganisa ubuchwepheshe be-optical nobuchwepheshe bama-elekthronikhi kungenye yezinketho zokufeza le nhloso ngokuzayo. Engqungqutheleni ye-EumW 2024 eParis, i-R & S ikhombisa umnikelo wayo ocwaningweni lwe-Terahertz olwenziwe ngobuso e-6g-Adlantik. Le phrojekthi igxile ekuthuthukisweni kwezakhi ze-Terahertz Frequency Range Range ezisuselwa ekuhlanganiseni izithombe kanye nama-elektroni. Lezi zingxenye ze-terahertz ezisazothuthukiswa ze-to-athuthukiswe zingasetjenziselwa izilinganiso ezintsha kanye nokudluliswa kwedatha okusheshayo. Lezi zingxenye zingasetshenziswa hhayi ukuxhumana kwe-6G kuphela, kodwa futhi nokuzwakala nokucabanga.
Iphrojekthi ye-6G-Adlantik ixhaswa yi-German Federal Instruct of Education and Research (BMBF) kanye nokuhlanganiswa yi-R & S. Abalingani bafaka i-toptica photonics AG, Fraunhofer-Institut HHI, Phowanics GmbH, Test University of Berlin kanye Spinner GmbH.
Uhlelo lwe-terartz oluqinile lwe-6G oluqinile olususelwa kubuchwepheshe be-Photon
Ubufakazi-bomqondo bukhombisa uhlelo lwe-terahert oluzinzile, oluqinile lwe-terable lwe-6G lokuhanjiswa kwedatha ye-6G ngokususelwa kuma-photoshini terahertz mixers akhiqiza ubuchwepheshe be-terahertz ngokususelwa kubuchwepheshe be-frequency ntroch. Kulesi simiso, i-PhotoDiode eguqula kahle amasiginali we-Optical Beat akhiqizwa ama-lasers anezankikazi ehlukile ama-optical ahlukahlukene abe amasiginali kagesi ngenqubo yokuxuba kwe-Photon. Isakhiwo se-antenna esizungeze i-Photoelectric Mixer siguqula i-Oscillating PhotoChating PhotoCoplent kumagagasi e-Terahertz. Isiginali ephumela singashintshwa futhi idonswe ukudilizwa kwe-6G futhi ingabuyiselwa kalula ibanga elijwayelekile. Uhlelo lunganwetshwa nezilinganiso zezakhi ezisebenzisa amasiginali atholakele atholwe ngokulandelana atholakele. Izakhiwo zezinhlaka ze-waveguide ze-terahertz waveguide kanye nokuthuthukiswa kwe-Ultra-Low-Low Isigaba Sokubhekelwa Oscillators nazo ziphakathi kwezindawo ezisebenzayo zephrojekthi.
Umsindo wesigaba ophansi we-Ultra-ophansi ngenxa ye-Frequency Comb-Locked Optical Frequency Synthensizer (of) enjini yeToptica Laser. Izinsimbi eziphakeme ze-R & S ziyingxenye ebalulekile yalolu hlelo: I-R & S SFI100A i-Windows Bagneband Uma i-Vector Signal Generator idala isibonakaliso se-baseband se-modulator ye-16gs / s. I-R & S SMA100B RF ne-Microwave Signal generator ikhiqiza isibonakaliso sewashi sewashi esizinzile se-toptica ofs Systems. I-R & S R & S RCILLOSCOPOPE Samples Isiginali ye-Baseband ngemuva kwe-PhotoCoductive Wave Recepy (CW) Terahertz Recerver (Rx) ngesilinganiso sesampula ka-40 gs / ukuvalwa kwesiginali yemvamisa engama-300 ghz.
6g ne-future Frequency band izidingo
I-6G izoletha izimo zesicelo ezintsha eziya embonini, ubuchwepheshe bezokwelapha kanye nokuphila kwansuku zonke. Izicelo ezifana ne-metacomes kanye neqiniso elingokoqobo (i-XR) zizobeka izimfuno ezintsha nge-latency kanye namanani wokudlulisa idatha akwazi ukufinyelelwa ngezinhlelo zamanje zokuxhumana. Ngenkathi ingqungquthela yomsakazo we-International Telecommunication Union 2023 (WRC23) ikhombe amabhendi amasha ku-FR3 Spectrum (7.125-24 GHz) ukuze aqhubeke nokucwaninga ngokoqobo (i-AR) augmented application (AR) kanye ne-ASTION HERTZ Band kuze kube yi-300 GHz okubaluleke kakhulu.
