Rohde & Schwarz (R&S) vakapa humbowo hwepfungwa yehurongwa hwekutumira data hwe6G husina waya hwakavakirwa pazvisungo zvekutaurirana zve photonic terahertz paEuropean Microwave Week (EuMW 2024) muParis, zvichibatsira kusimudzira miganhu ye tekinoroji dzenharembozha dzechizvarwa chinotevera. Sisitimu yeterahertz inogadziriswa yakasimba kwazvo yakagadzirwa muchirongwa che6G-ADLANTIK yakavakirwa pahunyanzvi hwekubatanidza ma frequency, ine ma carrier frequency ari pamusoro pe500GHz.
Munzira yekuenda ku6G, zvakakosha kugadzira masosi ekutumira terahertz anopa chiratidzo chemhando yepamusoro uye anogona kufukidza huwandu hwakakura hwema frequency. Kubatanidza tekinoroji ye optical ne electronic technology ndeimwe yesarudzo dzekuzadzisa chinangwa ichi mune ramangwana. Pamusangano weEuMW 2024 muParis, R&S inoratidza mupiro wayo mukutsvagisa kwe terahertz yemazuva ano muchirongwa che 6G-ADLANTIK. Chirongwa ichi chinotarisa pakugadzirwa kwezvikamu zve terahertz frequency range zvichibva pakubatanidzwa kwema photon nema electron. Izvi zvikamu zve terahertz zvisati zvagadzirwa zvinogona kushandiswa pakuyera kutsva uye kutamisa data nekukurumidza. Izvi zvikamu zvinogona kushandiswa kwete chete pakutaurirana kwe 6G, asiwo pakuona nekutora mifananidzo.
Chirongwa che6G-ADLANTIK chinotsigirwa nemari neGerman Federal Ministry of Education and Research (BMBF) uye chinotungamirwa neR&S. Vabatsiri vanosanganisira TOPTICA Photonics AG, Fraunhofer-Institut HHI, Microwave Photonics GmbH, Technical University of Berlin neSpinner GmbH.
Sisitimu ye6G inogona kugadziriswa zvakanaka uye yakagadzikana yakavakirwa patekinoroji ye photon
Humbowo hwepfungwa iyi hunoratidza sisitimu yeterahertz yakasimba uye inogadziriswa yekutumira data re 6G isina waya zvichibva pamichina ye photonic terahertz inogadzira masaini eterahertz zvichibva patekinoroji ye frequency comb. Musisitimu iyi, photodiode inoshandura masaini e optical beat akagadzirwa nema lasers ane ma frequency akasiyana zvishoma kuita masaini emagetsi kuburikidza nemaitiro ekusanganisa photon. Chimiro che antenna chakatenderedza muchina we photoelectric chinoshandura photocurrent inotenderera kuita ma terahertz waves. Chiratidzo chinobuda chinogona kugadziriswa uye kuderedzwa kuti chishandiswe pakutaurirana kwe 6G isina waya uye chinogona kugadziriswa zviri nyore pamusoro pehuwandu hwakawanda hwema frequency. Sisitimu iyi inogona zvakare kuwedzerwa kuzvikamu zvezvikamu uchishandisa masaini eterahertz akagamuchirwa zvakanaka. Kutevedzera uye dhizaini yezvimiro zve terahertz waveguide uye kugadzirwa kwe ultra-low phase noise photonic reference oscillators zviriwo pakati penzvimbo dzekushanda dzepurojekiti.
Ruzha rwechikamu chakaderera kwazvo rwesystem iyi rwunobva kufrequency comb-locked optical frequency synthesizer (OFS) muTOPTICA laser engine. Zvishandiso zvepamusoro zveR&S chikamu chakakosha chesystem iyi: Iyo R&S SFI100A wideband IF vector signal generator inogadzira baseband signal ye optical modulator ine sampling rate ye16GS/s. Iyo R&S SMA100B RF uye microwave signal generator inogadzira stable reference clock signal yeTOPTICA OFS systems. Iyo R&S RTP oscilloscope inoyedza baseband signal iri kuseri kwe photoconductive continuous wave (cw) terahertz receiver (Rx) pa sampling rate ye40 GS/s kuti iwedzere kugadziriswa uye kuderedzwa kwe300 GHz carrier frequency signal.
Zvinodiwa zvebhendi re6G uye remangwana rema frequency
6G ichaunza mamiriro matsva ekushandisa muindasitiri, tekinoroji yekurapa uye hupenyu hwezuva nezuva. Mashandisirwo akadai se metacomes ne Extended Reality (XR) achaisa zvinodiwa zvitsva pa latency uye data transfer rates izvo zvisingagone kuzadzikiswa nehurongwa hwekutaurirana huripo. Kunyange hazvo International Telecommunication Union's World Radio Conference 2023 (WRC23) yakaona mabhendi matsva muFR3 spectrum (7.125-24 GHz) ekutsvaga kumwe kwekutsvaga kwe network dzekutengesa dze6G dzekutanga kutanga muna 2030, Asi kuti zvizadzise kugona kwakazara kwe virtual reality (VR), augmented reality (AR) uye mixed reality (MR) applications, Asia-Pacific Hertz band inosvika 300 GHz ichave yakakoshawo.
