U-Rohde & Schwarz (R & S) ubonise ubungqina bobungqina benkqubo yokuhanjiswa kwedatha ye-wireless ye-6G esekelwe kwi-photonic terahertz ikhonkco lonxibelelwano kwiVeki yeMicrowave yaseYurophu (EuMW 2024) eParis, inceda ukuqhubela phambili umda we-teknoloji ye-wireless yesizukulwana esilandelayo. Inkqubo ye-terahertz ekwaziyo ukuzinza kakhulu ephuhliswe kwiprojekthi ye-6G-ADLANTIK isekwe kwitekhnoloji ye-comb frequency, kunye ne-frequencies ye-carrier kakhulu ngaphezu kwe-500GHz.
Endleleni eya kwi-6G, kubalulekile ukudala imithombo yothumelo lwe-terahertz ebonelela ngesignali ekumgangatho ophezulu kwaye inokugubungela uluhlu olubanzi olunokwenzeka. Ukudibanisa iteknoloji ye-optical kunye neteknoloji ye-elektroniki yenye yeendlela zokufezekisa le njongo kwixesha elizayo. Kwinkomfa ye-EuMW 2024 eParis, i-R&S ibonisa igalelo layo kuphando lwangoku lwe-terahertz kwiprojekthi ye-6G-ADLANTIK. Iprojekthi igxile ekuphuhliseni amacandelo oluhlu lwamaza e-terahertz ngokusekelwe ekudityanisweni kweefotoni kunye nee-electron. La macandelo e-terahertz engekaphuhliswa angasetyenziselwa imilinganiselo ehlaziyiweyo kunye nokudluliselwa kwedatha ngokukhawuleza. Ezi zixhobo zingasetyenziselwa kuphela unxibelelwano lwe-6G, kodwa kunye nokubona kunye nokucinga.
Iprojekthi ye-6G-ADLANTIK ixhaswa ngemali yi-German Federal Ministry of Education and Research (BMBF) kwaye iququzelelwe yi-R&S. Amaqabane aquka i-TOPTICA Photonics AG, i-Fraunhofer-Institut HHI, i-Microwave Photonics GmbH, i-Technical University yaseBerlin kunye ne-Spinner GmbH.
Inkqubo ye-terahertz ene-6G ye-ultra-stable esekelwe kwiteknoloji ye-photon
Ubungqina bengqikelelo bubonisa inkqubo ye-terahertz ene-ultra-stable, enokuqhutywa yi-6G yokuhanjiswa kwedatha engenazingcingo esekwe kwi-photonic terahertz mixers eyenza imiqondiso ye-terahertz esekwe kubuchwephesha be-comb frequency. Kule nkqubo, i-photodiode iguqula ngokufanelekileyo imiqondiso ye-optical beat eveliswa zii-laser ezinezandi ezahlukeneyo zokukhanya kwimiqondiso yombane ngenkqubo yokuxuba ifoton. Ulwakhiwo lwe-antenna olujikeleze umxubi wefoto yombane luguqula i-photocurrent ejikelezayo ibe ngamaza e-terahertz. Isibonakaliso esisiphumo sinokumodareyithwa kwaye sithotywe kunxibelelwano lwe-wireless lwe-6G kwaye lunokulungiswa ngokulula kuluhlu olubanzi. Inkqubo inokwandiswa kwimilinganiselo yecandelo kusetyenziswa imiqondiso ye-terahertz efunyenwe ngokuhambelanayo. Ukulinganisa kunye noyilo lwezakhiwo ze-terahertz waveguide kunye nophuhliso lwe-ultra-low isigaba se-oscillator ye-photonic reference oscillators nazo ziphakathi kweendawo zokusebenza zeprojekthi.
Ingxolo yenqanaba eliphantsi kakhulu lenkqubo ibulela kwi-frequency comb-locked optical frequency synthesizer (OFS) kwi-injini ye-laser ye-TOPTICA. Izixhobo eziphezulu ze-R & S ziyinxalenye ebalulekileyo yale nkqubo: I-R&S SFI100A i-wideband IF ijenereyitha ye-vector ye-vector yenza i-baseband signal ye-modulator ye-optical kunye ne-sampling rate ye-16GS / s. I-R&S SMA100B RF kunye nejenereyitha yomqondiso wemicrowave ivelisa uphawu oluzinzileyo lwewotshi yesalathiso kwiinkqubo ze-TOPTICA OFS. I-oscilloscope ye-R & S RTP isampula isignali ye-baseband emva kwe-photoconductive i-wave eqhubekayo (cw) i-terahertz receiver (Rx) kwi-sampling rate ye-40 GS / s yokuqhubela phambili kunye nokuchithwa kwe-300 GHz isignali ye-carrier carrier frequency.
I-6G kunye neemfuno zebhendi yexesha elizayo
I-6G iza kuzisa iimeko ezintsha zesicelo kwishishini, iteknoloji yezonyango kunye nobomi bemihla ngemihla. Izicelo ezifana ne-metacomes kunye ne-Extended Reality (XR) ziya kubeka iimfuno ezintsha kwi-latency kunye namazinga okudluliselwa kwedatha angenako ukuhlangabezana neenkqubo zonxibelelwano lwangoku. Ngelixa i-International Telecommunication Union's World Radio Conference 2023 (WRC23) ichonge iibhendi ezintsha kwi-FR3 spectrum (7.125-24 GHz) kuphando olongezelelweyo lothungelwano lokuqala lwe-6G yorhwebo oluza kusungulwa ngo-2030, Kodwa ukuqonda amandla apheleleyo enyani yenyani. (VR), inyani eyandisiweyo (AR) kunye nenyaniso edibeneyo (MR) izicelo, i-Asia-Pacific Hertz band ukuya kwi-300 I-GHz nayo iya kuba yimfuneko.
