Rohde & Schwarz (R&S) adapereka umboni wa lingaliro la njira yotumizira deta ya 6G yopanda zingwe yozikidwa pa maulalo olumikizirana a photonic terahertz pa European Microwave Week (EuMW 2024) ku Paris, zomwe zathandiza kupititsa patsogolo ukadaulo wamakono wopanda zingwe. Dongosolo la terahertz losinthika lokhazikika kwambiri lomwe linapangidwa mu pulojekiti ya 6G-ADLANTIK limachokera ku ukadaulo wa pafupipafupi, wokhala ndi ma frequency onyamula omwe ali pamwamba pa 500GHz.
Paulendo wopita ku 6G, ndikofunikira kupanga magwero otumizira ma terahertz omwe amapereka chizindikiro chapamwamba kwambiri ndipo amatha kuphimba ma frequency ambiri momwe angathere. Kuphatikiza ukadaulo wa kuwala ndi ukadaulo wamagetsi ndi njira imodzi yokwaniritsira cholinga ichi mtsogolo. Pamsonkhano wa EuMW 2024 ku Paris, R&S ikuwonetsa zomwe yachita pakufufuza kwamakono kwa terahertz mu projekiti ya 6G-ADLANTIK. Pulojekitiyi ikuyang'ana kwambiri pakupanga zigawo za frequency za terahertz kutengera kuphatikiza kwa ma photon ndi ma electron. Zigawo za terahertz zomwe sizinapangidwezi zitha kugwiritsidwa ntchito poyesa zatsopano komanso kutumiza deta mwachangu. Zigawozi zitha kugwiritsidwa ntchito osati polankhulana ndi 6G kokha, komanso pozindikira ndi kujambula.
Pulojekiti ya 6G-ADLANTIK imathandizidwa ndi Unduna wa Maphunziro ndi Kafukufuku wa Federal ku Germany (BMBF) ndipo imayendetsedwa ndi R&S. Ogwirizana nawo ndi TOPTICA Photonics AG, Fraunhofer-Institut HHI, Microwave Photonics GmbH, Technical University of Berlin ndi Spinner GmbH.
Dongosolo la terahertz losinthika la 6G lokhazikika kwambiri lozikidwa pa ukadaulo wa photon
Umboni wa lingaliroli ukuwonetsa dongosolo la terahertz lokhazikika komanso losinthika kwambiri lotumizira deta ya 6G yopanda zingwe kutengera zosakaniza za photonic terahertz zomwe zimapanga zizindikiro za terahertz kutengera ukadaulo wa frequency comb. Mu dongosololi, photodiode imasintha bwino zizindikiro za optical beat zopangidwa ndi ma laser okhala ndi ma frequency osiyana pang'ono kukhala zizindikiro zamagetsi kudzera mu njira yosakanikirana ndi photon. Kapangidwe ka antenna kozungulira chosakaniza cha photoelectric kamasintha photocurrent yozungulira kukhala mafunde a terahertz. Chizindikiro chomwe chimachokera chikhoza kusinthidwa ndikusinthidwa kuti chilumikizane ndi 6G opanda zingwe ndipo chikhoza kusinthidwa mosavuta pamitundu yosiyanasiyana ya ma frequency. Dongosololi likhozanso kukulitsidwa ku miyeso ya zigawo pogwiritsa ntchito zizindikiro za terahertz zolandiridwa bwino. Kuyerekeza ndi kapangidwe ka kapangidwe ka mafunde a terahertz ndi chitukuko cha ma oscillator a photonic reference a ultra-low phase noise ndi ena mwa madera ogwirira ntchito a pulojekitiyi.
Phokoso la gawo lotsika kwambiri la dongosololi limachitika chifukwa cha frequency comb-locked optical frequency synthesizer (OFS) mu injini ya laser ya TOPTICA. Zida zapamwamba za R&S ndi gawo lofunikira la dongosololi: Jenereta ya chizindikiro cha vector ya R&S SFI100A wideband IF imapanga chizindikiro cha baseband cha optical modulator chokhala ndi sampling rate ya 16GS/s. Jenereta ya chizindikiro cha R&S SMA100B RF ndi microwave imapanga chizindikiro chokhazikika cha wotchi ya TOPTICA OFS systems. R&S RTP oscilloscope imayesa chizindikiro cha baseband kumbuyo kwa photoconductive continuous wave (cw) terahertz receiver (Rx) pa sampling rate ya 40 GS/s kuti ikonzedwenso ndikusinthidwa kwa chizindikiro cha frequency cha 300 GHz carrier.
Zofunikira pa 6G ndi mtsogolo pa bandeji ya ma frequency
6G idzabweretsa zochitika zatsopano zogwiritsira ntchito m'makampani, ukadaulo wazachipatala komanso moyo watsiku ndi tsiku. Mapulogalamu monga metacomes ndi Extended Reality (XR) adzaika zofunikira zatsopano pa kuchedwa ndi kusamutsa deta zomwe sizingakwaniritsidwe ndi njira zamakono zolumikizirana. Ngakhale Msonkhano Wapadziko Lonse wa Pawailesi Yapadziko Lonse wa International Telecommunication Union wa 2023 (WRC23) wapeza magulu atsopano mu FR3 spectrum (7.125-24 GHz) kuti afufuze zambiri za maukonde oyamba amalonda a 6G omwe adzayambitsidwe mu 2030, Koma kuti akwaniritse kuthekera konse kwa ntchito zenizeni zenizeni (VR), zenizeni zowonjezeredwa (AR) ndi zenizeni zosakanikirana (MR), gulu la Asia-Pacific Hertz mpaka 300 GHz lidzakhala lofunikira kwambiri.
