Rohde & Schwarz (R&S) batanze igihamya cy’igitekerezo cy’uburyo bwo kohereza amakuru ya 6G adafite insinga bushingiye ku miyoboro y’itumanaho ya terahertz ikoresheje ikoranabuhanga rya photonic mu cyumweru cya Microwave (EuMW 2024) i Paris, bifasha mu guteza imbere ikoranabuhanga rigezweho ridafite insinga. Sisitemu ya terahertz ihindagurika cyane yakozwe mu mushinga wa 6G-ADLANTIK ishingiye ku ikoranabuhanga ryo gukurura amakuru, aho umuvuduko w’itumanaho urenga cyane 500GHz.
Mu nzira igana kuri 6G, ni ngombwa gukora amasoko yo kohereza terahertz atanga ikimenyetso cyiza kandi ashobora gukwirakwira ku rugero rwagutse rushoboka rw'umuvuduko. Guhuza ikoranabuhanga rya optique n'ikoranabuhanga rya elegitoroniki ni imwe mu nzira zo kugera kuri iyi ntego mu gihe kizaza. Mu nama ya EuMW 2024 i Paris, R&S yerekana uruhare rwayo mu bushakashatsi bugezweho bwa terahertz mu mushinga wa 6G-ADLANTIK. Uyu mushinga wibanda ku iterambere ry'ibice by'umuvuduko wa terahertz bishingiye ku guhuza fotoni na electron. Ibi bice bya terahertz bitarakorwa bishobora gukoreshwa mu gupima udushya no kohereza amakuru vuba. Ibi bice bishobora gukoreshwa atari mu itumanaho rya 6G gusa, ahubwo no mu kumva no gufata amashusho.
Umushinga wa 6G-ADLANTIK uterwa inkunga na Minisiteri y’Uburezi n’Ubushakashatsi y’Ubudage (BMBF) kandi uhuzwa n’ikigo gishinzwe ubushakashatsi n’ubushakashatsi (R&S). Abafatanyabikorwa barimo TOPTICA Photonics AG, Fraunhofer-Institut HHI, Microwave Photonics GmbH, Kaminuza y’Ubuhanga ya Berlin na Spinner GmbH.
Sisitemu ya terahertz ihindagurika cyane ya 6G ishingiye ku ikoranabuhanga rya photon
Icyemeza-igitekerezo kigaragaza sisitemu ya terahertz ihamye kandi ishobora guhindurwa yo kohereza amakuru ya 6G ikoresheje insinga zivanze za terahertz zikora ibimenyetso bya terahertz bishingiye ku ikoranabuhanga rya frequency comb. Muri iyi sisitemu, photodiode ihindura neza ibimenyetso bya optique bitangwa na lasers zifite frequencies zitandukanye gato mu bimenyetso by'amashanyarazi binyuze mu nzira yo kuvanga photon. Imiterere ya antene izengurutse insinga zivanze photoelectric ihindura umuyoboro wa photocurrent uhindagurika mu miraba ya terahertz. Ikimenyetso gisohoka gishobora guhindurwa no guhindurwa kugira ngo gikoreshwe mu itumanaho rya 6G ridafite insinga kandi gishobora guhindurwa byoroshye mu ntera nini y'imiyoboro. Sisitemu ishobora kandi kwagurirwa ku bipimo by'ibice hakoreshejwe ibimenyetso bya terahertz byakiranywe neza. Imiterere n'imiterere y'imiterere ya terahertz waveguide hamwe n'iterambere rya oscillators za photonic reference oscillators zifite urusaku rwo hasi cyane nabyo biri mu bice by'umushinga.
Urusaku rwo hasi cyane rw'iyi sisitemu ruturuka kuri synthesizer ya frequency optical frequency synthesizer (OFS) iri muri moteri ya laser ya TOPTICA. Ibikoresho byo mu rwego rwo hejuru bya R&S ni igice cy'ingenzi cy'iyi sisitemu: Imashini ikora ikimenyetso cya vector ya R&S SFI100A ya wideband IF ikora ikimenyetso cya baseband kuri modulator y'amajwi ifite igipimo cyo gupima cya 16GS/s. Imashini ikora ikimenyetso cya microwave ya R&S SMA100B RF na microwave itanga ikimenyetso cy'isaha ihamye kuri sisitemu za TOPTICA OFS. Imashini ya R&S RTP oscilloscope ipima ikimenyetso cya baseband inyuma ya photoconductive continuous wave (cw) terahertz receiver (Rx) ku gipimo cyo gupima cya 40 GS/s kugira ngo ikomeze gutunganya no gukuraho ikimenyetso cya frequency ya 300 GHz.
Ibisabwa kuri 6G n'umuyoboro w'amajwi y'igihe kizaza
6G izazana uburyo bushya bwo gukoresha porogaramu mu nganda, ikoranabuhanga ry’ubuvuzi n’ubuzima bwa buri munsi. Porogaramu nka metacomes na Extended Reality (XR) zizashyiraho ibisabwa bishya ku gipimo cyo gutinda no kohereza amakuru kidashobora kuzuzwa na sisitemu z’itumanaho zigezweho. Nubwo Inama Mpuzamahanga y’Itumanaho ku Isi ya Radiyo Mpuzamahanga yo mu 2023 (WRC23) yasanze amatsinda mashya mu buryo bwa FR3 (7.125-24 GHz) kugira ngo hakorwe ubushakashatsi ku miyoboro ya mbere y’ubucuruzi ya 6G izatangizwa mu 2030, Ariko kugira ngo haboneke ubushobozi bwuzuye bwa porogaramu z’ukuri kuri interineti (VR), ukuri kwaguweho (AR) na porogaramu zivanze (MR), amatsinda ya Hertz yo muri Aziya-Pasifika agera kuri 300 GHz nayo azaba ari ingenzi cyane.
