Pakazosvika 2030, 6G nharembozha inotarisirwa kuvhura nzira yezvishandiso zvitsva zvakaita sehungwaru hwekugadzira, chokwadi chaicho uye Internet yezvinhu.Izvi zvinoda kushanda kwepamusoro pane yazvino 5G mobile standard uchishandisa mitsva yehardware mhinduro.Saka nekudaro, paEuMW 2022, Fraunhofer IAF ichange ichiratidzira gaN transmitter module inogadzirisa simba yakagadziridzwa pamwe chete neFraunhofer HHI ye6G frequency renji inoenderana ne70 GHz.Kuita kwepamusoro kwe module iyi kwakasimbiswa naFraunhofer HHI.
Mota dzinozvimirira, telemedicine, mafekitori ega - ese aya mashandisirwo emangwana mukufambisa, hutano uye indasitiri inotsamira paruzivo uye kutaurirana matekinoroji anoenda kupfuura kugona kwechizvarwa chechishanu (5G) nharembozha yekutaurirana.Iyo inotarisirwa kutangwa kwe6G nharembozha mu2030 inovimbisa kupa inodiwa yakakwirira-kumhanya network ye data data inodiwa mune ramangwana, ine data data inodarika 1 Tbps uye latency kusvika ku100 µs.
Kubva 2019 sechirongwa cheKONFEKT ("6G Kukurukurirana Zvikamu").
Vatsvakurudzi vakagadzira transmission modules yakavakirwa pa gallium nitride (GaN) simba semiconductor, iyo kekutanga inogona kushandisa frequency renji ingangoita 80 GHz (E-band) uye 140 GHz (D-band).Iyo itsva E-band transmitter module, ine maitiro epamusoro akaedzwa zvakabudirira naFraunhofer HHI, ichaunzwa kune nyanzvi yeruzhinji kuEuropean Microwave Week (EuMW) muMilan, Italy, kubva 25 kusvika 30 Gunyana 2022.
"Nokuda kwekuda kwepamusoro pekushanda nekushanda, 6G inoda mhando itsva dzemichina," anotsanangura kudaro Dr. Michael Mikulla kubva kuFraunhofer IAF, uyo ari kuronga chirongwa cheKONFEKT.“Nhasi zvinhu zvechizvino-zvino zvave kusvika pakunogumira.Izvi zvinonyanya kushanda kune iri pasi semiconductor tekinoroji, pamwe nekusangana uye antenna tekinoroji.Kuti tive nemigumisiro yakanakisisa maererano nekubuda kwesimba, bandwidth uye kushanda kwesimba, tinoshandisa GaN-based monolithic integration Microwave Microwave Circuits (MMIC) yemodule yedu inotsiva kushandiswa kwesilicon circuits ikozvino. , ichipa kurasikirwa kwakanyanya kwakaderera uye mamwe macompact components.Pamusoro pezvo, tiri kubva kure nepamusoro pegomo uye planar dhizaini mapakeji ekugadzira yakaderera-kurasikirwa kwebeamforming architecture ane waveguides uye akavakirwa-mukati akafanana maseketi.
Fraunhofer HHI ari kuitawo basa mukuongororwa kwe 3D yakadhindwa waveguides.Zvikamu zvinoverengeka zvakagadzirwa, kugadzirwa uye kuratidzwa uchishandisa yakasarudzika laser melting (SLM) maitiro, anosanganisira emagetsi splitters, antennas uye antenna feeds.Iyo nzira inobvumirawo kukurumidza uye kusingadhuri kugadzirwa kwezvikamu zvisingakwanisi kugadzirwa uchishandisa nzira dzechinyakare, zvichigadzira nzira yekuvandudza tekinoroji ye6G.
"Kuburikidza nehunyanzvi hwehunyanzvi uhu, Fraunhofer Institutes IAF neHHI inobvumira Germany neEurope kutora danho rakakosha kune remangwana rekufambiswa kwenharembozha, panguva imwechete ichiita mupiro unokosha mukuzvitonga kwenyika," akadaro Mikula.
Iyo E-bhendi module inopa 1W yemutsara wekubuda simba kubva pa81 GHz kusvika 86 GHz nekubatanidza simba rekutumira remamodule mana akaparadzana neakanyanya kuderera kurasikirwa waveguide musangano.Izvi zvinoita kuti ive yakakodzera kune Broadband point-to-point data links pamusoro pemarefu madaro, yakakosha kugona kune ramangwana 6G architecture.
Kuedza kwakasiyana-siyana kwekufambisa kwakaitwa naFraunhofer HHI kwakaratidza kushanda kwezvikamu zvakabatanidzwa: mumamiriro akasiyana-siyana ekunze, zviratidzo zvinopindirana nezvino 5G yekusimudzira tsanangudzo (5G-NR Release 16 ye3GPP GSM standard).Pa85 GHz, bandwidth iri 400 MHz.
Iine mutsara-wekuona, data inofambiswa zvinobudirira kusvika ku600 metres mu64-chiratidzo Quadrature Amplitude Modulation (64-QAM), ichipa yakakwirira bandwidth kushanda kwe6 bps/Hz.Iyo yakagamuchirwa chiratidzo chemhosho vector magnitude (EVM) ndeye -24.43 dB, iri pasi peiyo 3GPP muganhu we -20.92 dB.Nekuti mutsara wekuona wakavharwa nemiti uye mota dzakamiswa, 16QAM modulated data inogona kufambiswa zvinobudirira kusvika ku150 metres.Quadrature modulation data (quadrature phase shift keying, QPSK) inogona kutapurirwa uye kugamuchirwa zvinobudirira pakuita zvakanaka kwe2 bps/Hz kunyangwe mutsara wekuona pakati pemupepeti nemugamuchiri wakavharwa zvachose.Muzviitiko zvese, chiratidzo chepamusoro-ku-ruzha reshiyo, dzimwe nguva inopfuura 20 dB, yakakosha, kunyanya kufunga nezve frequency renji, uye inogona kuwanikwa chete nekuwedzera kushanda kwezvikamu.
Munzira yechipiri, transmitter module yakagadziridzwa ye frequency range yakatenderedza 140 GHz, ichibatanidza simba rekubuda rinopfuura zana mW nehupamhi bandwidth ye20 GHz.Kuedzwa kwemodule iyi kuchiri kumberi.Ose maviri mamodule module akakodzera zvikamu zvekugadzira uye kuyedza ramangwana 6G masisitimu mune terahertz frequency renji.
