Rohde & Schwarz (R&S) waxay soo bandhigeen caddayn fikrad ah oo ku saabsan nidaamka gudbinta xogta wireless-ka ee 6G oo ku salaysan isku xirka isgaarsiinta terahertz ee photonic ee Toddobaadka Microwave-ka Yurub (EuMW 2024) ee Paris, taasoo gacan ka geysaneysa horumarinta xuduudaha teknoolojiyada wireless-ka ee jiilka soo socda. Nidaamka terahertz ee aadka u deggan ee lagu sameeyay mashruuca 6G-ADLANTIK wuxuu ku salaysan yahay tignoolajiyada shanlada soo noqnoqda, iyadoo mawjadaha sideyaashu ay si weyn uga sarreeyaan 500GHz.
Wadada loo marayo 6G, waxaa muhiim ah in la abuuro ilo gudbin terahertz ah oo bixiya calaamad tayo sare leh isla markaana dabooli karta baaxadda ugu ballaaran ee suurtogalka ah. Isku-darka tignoolajiyada indhaha iyo tignoolajiyada elektaroonigga ah waa mid ka mid ah fursadaha lagu gaari karo yoolkan mustaqbalka. Shirka EuMW 2024 ee ka dhacaya Paris, R&S waxay ku soo bandhigaysaa ka qayb qaadashadeeda cilmi-baarista terahertz ee casriga ah ee mashruuca 6G-ADLANTIK. Mashruucu wuxuu diiradda saarayaa horumarinta qaybaha kala duwan ee kala duwan ee terahertz iyadoo lagu saleynayo isku-dhafka fotonnada iyo elektroonnada. Qaybahan terahertz ee aan weli la horumarin waxaa loo isticmaali karaa cabbiraadaha cusub iyo wareejinta xogta si dhakhso leh. Qaybahan waxaa loo isticmaali karaa oo keliya isgaarsiinta 6G, laakiin sidoo kale dareenka iyo sawir-qaadista.
Mashruuca 6G-ADLANTIK waxaa maalgelisay Wasaaradda Waxbarashada iyo Cilmi-baarista ee Federaalka Jarmalka (BMBF) waxaana isku dubariday R&S. Wada-hawlgalayaasha waxaa ka mid ah TOPTICA Photonics AG, Fraunhofer-Institut HHI, Microwave Photonics GmbH, Jaamacadda Farsamada ee Berlin iyo Spinner GmbH.
Nidaam terahertz oo 6G ah oo aad u deggan oo ku salaysan tignoolajiyada photon
Caddeynta fikradda waxay muujinaysaa nidaam terahertz ah oo aad u deggan oo la hagaajin karo oo loogu talagalay gudbinta xogta wireless-ka 6G oo ku salaysan isku-darka terahertz ee photonic kuwaas oo soo saara calaamadaha terahertz iyadoo lagu saleynayo tiknoolajiyada shanlada soo noqnoqda. Nidaamkan, photodiode-ku wuxuu si wax ku ool ah u beddelaa calaamadaha garaaca indhaha ee ay soo saaraan laysarka leh mawjadaha indhaha ee waxoogaa kala duwan una beddelaa calaamadaha korontada iyada oo loo marayo habka isku-darka photon. Qaab-dhismeedka anteenada ee ku wareegsan isku-darka photoelectric-ka wuxuu u beddelaa photocurrent-ka oscillating mowjadaha terahertz. Calaamadda ka dhalata waa la beddeli karaa oo la dhimi karaa isgaarsiinta wireless-ka 6G waxaana si fudud loogu hagaajin karaa baaxad ballaaran oo soo noqnoqosho ah. Nidaamka waxaa sidoo kale loo fidin karaa cabbirrada qaybaha iyadoo la adeegsanayo calaamadaha terahertz ee si isku xiran loo helay. Jilitaanka iyo naqshadeynta qaab-dhismeedka hagaha hirarka terahertz iyo horumarinta oscillators tixraaca photonic ee heerka aadka u hooseeya ayaa sidoo kale ka mid ah meelaha shaqada ee mashruuca.
Buuqa marxaladda aadka u hooseeya ee nidaamka waxaa ugu wacan isku-darka soo noqnoqda ee iftiinka ee shanlada ku xiran (OFS) ee ku jira matoorka leysarka TOPTICA. Qalabka sare ee R&S waa qayb muhiim ah oo ka mid ah nidaamkan: Matoorka calaamadaha vector-ka ee R&S SFI100A ee ballaaran wuxuu abuuraa calaamad saldhig-baseband ah oo loogu talagalay modulator-ka indhaha oo leh heer muunad ah oo ah 16GS/s. Matoorka calaamadaha R&S SMA100B RF iyo matoorka calaamadaha microwave-ka wuxuu soo saaraa calaamad saacad tixraac oo deggan oo loogu talagalay nidaamyada TOPTICA OFS. Oscilloscope-ka R&S RTP wuxuu tijaabiyaa calaamadda salka-baseband ee ka dambeysa qaataha terahertz ee hirarka joogtada ah (cw) ee sawir-qaadaha (Rx) oo leh heer muunad ah oo ah 40 GS/s si loo sii farsameeyo loona soo saaro calaamadda soo noqnoqoshada side-ka 300 GHz.
6G iyo shuruudaha xarigga soo noqnoqda ee mustaqbalka
6G waxay xaaladaha codsiga cusub u keeni doontaa warshadaha, tignoolajiyada caafimaadka iyo nolol maalmeedka. Codsiyada sida metacomes iyo Extended Reality (XR) waxay dalban doonaan dalabyo cusub oo ku saabsan heerka dib u dhaca iyo wareejinta xogta oo aan lagu dabooli karin nidaamyada isgaarsiinta ee hadda jira. Iyadoo Shirka Raadiyaha Adduunka ee Ururka Isgaarsiinta Caalamiga ah 2023 (WRC23) uu aqoonsaday kooxo cusub oo ku jira FR3 spectrum (7.125-24 GHz) si loo sameeyo cilmi-baaris dheeraad ah oo loogu talagalay shabakadaha 6G ee ganacsiga ugu horreeya ee la bilaabayo 2030, Laakiin si loo xaqiijiyo awoodda buuxda ee xaqiiqada dalwaddu (VR), xaqiiqada la kordhiyay (AR) iyo codsiyada xaqiiqada isku dhafan (MR), kooxda Hertz ee Aasiya-Pacific ilaa 300 GHz ayaa sidoo kale lama huraan noqon doonta.
