Rohde & Schwarz (R&S) tau nthuav tawm cov ntaub ntawv pov thawj-ntawm-lub tswv yim rau 6G wireless cov ntaub ntawv xa mus raws li kev sib txuas lus photonic terahertz ntawm European Microwave Week (EuMW 2024) hauv Paris, pab txhawb rau pem hauv ntej ntawm lwm tiam wireless technologies. Lub ultra-stable tunable terahertz system tsim nyob rau hauv 6G-ADLANTIK project yog raws li nyob rau hauv zaus comb technology, nrog rau cov cab kuj frequencies ho siab tshaj 500GHz.
Ntawm txoj kev mus rau 6G, nws yog ib qho tseem ceeb los tsim terahertz kis tau tus mob qhov chaw uas muab lub teeb liab zoo thiab tuaj yeem npog qhov ntau zaus. Kev sib koom ua ke ntawm kev siv tshuab kho qhov muag nrog cov tshuab hluav taws xob yog ib qho kev xaiv kom ua tiav lub hom phiaj no yav tom ntej. Ntawm EuMW 2024 lub rooj sib tham hauv Paris, R&S nthuav qhia nws txoj kev koom tes rau kev tshawb fawb terahertz hauv 6G-ADLANTIK project. Qhov project tsom mus rau kev txhim kho ntawm terahertz zaus ntau yam khoom raws li kev koom ua ke ntawm photons thiab electrons. Cov tseem-rau-tau-tsim terahertz Cheebtsam no tuaj yeem siv rau kev ntsuas tshiab thiab hloov cov ntaub ntawv sai dua. Cov khoom siv no tuaj yeem siv tsis tau tsuas yog rau 6G kev sib txuas lus, tab sis kuj rau kev hnov lus thiab duab.
Txoj haujlwm 6G-ADLANTIK yog nyiaj txiag los ntawm German Federal Ministry of Education thiab Research (BMBF) thiab koom tes los ntawm R&S. Cov koom tes suav nrog TOPTICA Photonics AG, Fraunhofer-Institut HHI, Microwave Photonics GmbH, Technical University of Berlin thiab Spinner GmbH.
6G ultra-stable tunable terahertz system raws li photon technology
Cov ntaub ntawv pov thawj-ntawm-lub tswv yim qhia tau tias muaj kev ruaj khov, tunable terahertz system rau 6G wireless cov ntaub ntawv xa mus raws li photonic terahertz mixers uas tsim cov cim terahertz raws li kev siv tshuab zaus. Nyob rau hauv no system, lub photodiode zoo converts optical yeej teeb liab generated los ntawm lasers nrog me ntsis txawv optical frequencies mus rau hauv hluav taws xob signals los ntawm cov txheej txheem ntawm photon mixing. Cov qauv kav hlau txais xov nyob ib ncig ntawm lub tshuab hluav taws xob photoelectric hloov lub oscillating photocurrent mus rau terahertz tsis. Cov teeb liab tshwm sim tuaj yeem hloov kho thiab demodulated rau 6G wireless kev sib txuas lus thiab tuaj yeem hloov kho tau yooj yim dua li ntau zaus. Lub kaw lus kuj tseem tuaj yeem txuas ntxiv mus rau qhov ntsuas ntsuas siv sib txuas tau txais cov cim terahertz. Kev simulation thiab tsim ntawm terahertz waveguide cov qauv thiab kev txhim kho ntawm ultra-low-theem suab nrov photonic siv oscillators kuj yog cov chaw ua haujlwm ntawm qhov project.
Lub suab nrov ultra-low theem ntawm lub kaw lus yog ua tsaug rau qhov zaus comb-locked optical zaus synthesizer (OFS) hauv TOPTICA laser cav. R&S cov cuab yeej high-end yog ib qho tseem ceeb ntawm cov kab ke no: R&S SFI100A wideband IF vector teeb liab generator tsim ib lub teeb liab baseband rau optical modulator nrog tus nqi piv txwv ntawm 16GS / s. R&S SMA100B RF thiab microwave teeb liab lub tshuab hluav taws xob ua kom muaj kev ruaj ntseg siv moos teeb liab rau TOPTICA OFS systems. R&S RTP oscilloscope kuaj cov teeb liab baseband tom qab photoconductive nruam nthwv dej (cw) terahertz receiver (Rx) ntawm tus nqi piv txwv ntawm 40 GS / s rau kev ua ntxiv thiab demodulation ntawm 300 GHz cab kuj zaus teeb liab.
6G thiab yav tom ntej zaus band yuav tsum
6G yuav coj cov xwm txheej tshiab rau kev lag luam, kev kho mob thev naus laus zis thiab lub neej niaj hnub. Cov ntawv thov xws li metacomes thiab Extended Reality (XR) yuav tso cov kev xav tau tshiab ntawm latency thiab cov ntaub ntawv hloov pauv cov ntaub ntawv uas tsis tuaj yeem ntsib los ntawm cov kev sib txuas lus tam sim no. Thaum lub International Telecommunication Union's World Radio Conference 2023 (WRC23) tau txheeb xyuas cov bands tshiab hauv FR3 spectrum (7.125-24 GHz) rau kev tshawb fawb ntxiv rau thawj cov lag luam 6G tes hauj lwm yuav tsum tau pib hauv 2030, Tab sis kom paub txog tag nrho cov peev xwm ntawm kev muaj tiag virtual. (VR), augmented kev muaj tiag (AR) thiab sib xyaw kev muaj tiag (MR) daim ntawv thov, Asia-Pacific Hertz band mus txog 300 GHz kuj tseem yuav yog qhov tseem ceeb.
