Rohde & Schwarz (R&S) tau nthuav tawm ib qho pov thawj ntawm lub tswv yim rau lub kaw lus xa cov ntaub ntawv wireless 6G raws li kev sib txuas lus photonic terahertz ntawm European Microwave Week (EuMW 2024) hauv Paris, pab txhawb kev nce qib ntawm cov thev naus laus zis wireless tiam tom ntej. Lub kaw lus terahertz tunable ultra-stable uas tsim nyob rau hauv 6G-ADLANTIK project yog raws li cov thev naus laus zis sib txuas zaus, nrog rau cov zaus nqa khoom siab dua 500GHz.
Nyob rau ntawm txoj kev mus rau 6G, nws yog ib qho tseem ceeb los tsim cov chaw xa xov terahertz uas muab cov teeb liab zoo thiab tuaj yeem npog qhov ntau zaus tshaj plaws. Kev sib xyaw ua ke ntawm cov thev naus laus zis kho qhov muag nrog cov thev naus laus zis hluav taws xob yog ib qho ntawm cov kev xaiv los ua tiav lub hom phiaj no yav tom ntej. Ntawm lub rooj sib tham EuMW 2024 hauv Paris, R&S qhia txog nws txoj kev koom tes rau kev tshawb fawb terahertz tshiab hauv qhov project 6G-ADLANTIK. Qhov project tsom mus rau kev txhim kho cov khoom siv zaus terahertz raws li kev koom ua ke ntawm photons thiab electrons. Cov khoom siv terahertz no tseem tsis tau tsim kho tuaj yeem siv rau kev ntsuas tshiab thiab kev xa cov ntaub ntawv sai dua. Cov khoom siv no tuaj yeem siv tsis yog rau kev sib txuas lus 6G xwb, tab sis kuj rau kev ntes thiab thaij duab.
Qhov project 6G-ADLANTIK tau txais nyiaj los ntawm German Federal Ministry of Education and Research (BMBF) thiab tswj hwm los ntawm R&S. Cov neeg koom tes suav nrog TOPTICA Photonics AG, Fraunhofer-Institut HHI, Microwave Photonics GmbH, Technical University of Berlin thiab Spinner GmbH.
Ib lub 6G ultra-stable tunable terahertz system raws li photon technology
Cov pov thawj ntawm lub tswv yim qhia txog lub kaw lus terahertz uas ruaj khov heev, kho tau rau 6G wireless cov ntaub ntawv xa mus los raws li photonic terahertz mixers uas tsim cov teeb liab terahertz raws li cov thev naus laus zis sib xyaw zaus. Hauv lub kaw lus no, lub photodiode hloov cov teeb liab optical beat uas tsim los ntawm lasers nrog cov zaus optical sib txawv me ntsis rau hauv cov teeb liab hluav taws xob los ntawm cov txheej txheem ntawm photon sib xyaw. Lub qauv antenna nyob ib puag ncig lub photoelectric mixer hloov cov oscillating photocurrent mus rau hauv terahertz nthwv dej. Cov teeb liab tshwm sim tuaj yeem hloov kho thiab demodulated rau 6G wireless kev sib txuas lus thiab tuaj yeem kho tau yooj yim hla ntau qhov zaus. Lub kaw lus kuj tseem tuaj yeem txuas ntxiv mus rau kev ntsuas cov khoom siv siv cov teeb liab terahertz tau txais sib xws. Kev sim thiab tsim cov qauv terahertz waveguide thiab kev txhim kho ntawm ultra-low phase noise photonic reference oscillators kuj yog cov haujlwm ua haujlwm ntawm qhov project.
Lub suab nrov ultra-low theem ntawm lub kaw lus yog ua tsaug rau qhov zaus comb-locked optical frequency synthesizer (OFS) hauv TOPTICA laser engine. R&S cov cuab yeej siv siab kawg yog ib feem tseem ceeb ntawm lub kaw lus no: R&S SFI100A wideband IF vector teeb liab generator tsim lub teeb liab baseband rau lub optical modulator nrog tus nqi sampling ntawm 16GS / s. R&S SMA100B RF thiab microwave teeb liab generator tsim lub teeb liab moos ruaj khov rau TOPTICA OFS systems. R&S RTP oscilloscope kuaj lub teeb liab baseband tom qab lub photoconductive continuous wave (cw) terahertz receiver (Rx) ntawm tus nqi sampling ntawm 40 GS / s rau kev ua tiav ntxiv thiab demodulation ntawm 300 GHz carrier zaus teeb liab.
6G thiab cov kev xav tau ntawm cov zaus band yav tom ntej
6G yuav coj cov xwm txheej tshiab rau kev siv hauv kev lag luam, kev kho mob thiab lub neej txhua hnub. Cov ntawv thov xws li metacomes thiab Extended Reality (XR) yuav tso cov kev xav tau tshiab rau latency thiab cov nqi xa cov ntaub ntawv uas cov kab ke sib txuas lus tam sim no tsis tuaj yeem ua tau. Thaum Lub Rooj Sib Tham Xov Tooj Cua Thoob Ntiaj Teb Xyoo 2023 (WRC23) tau txheeb xyuas cov kab ke tshiab hauv FR3 spectrum (7.125-24 GHz) rau kev tshawb fawb ntxiv rau thawj lub network 6G lag luam uas yuav tsim tawm xyoo 2030, Tab sis kom paub txog tag nrho lub peev xwm ntawm virtual reality (VR), augmented reality (AR) thiab mixed reality (MR) daim ntawv thov, Asia-Pacific Hertz band txog li 300 GHz kuj tseem yuav tsis tseem ceeb.
