Pofika chaka cha 2030, mauthenga a m'manja a 6G akuyembekezeka kutsegulira njira zogwiritsira ntchito zatsopano monga luntha lochita kupanga, zenizeni zenizeni ndi intaneti ya Zinthu.Izi zidzafuna magwiridwe antchito apamwamba kuposa momwe 5G ilili pano pogwiritsa ntchito njira zatsopano za Hardware.Momwemonso, ku EuMW 2022, Fraunhofer IAF ikuwonetsa gawo lopatsa mphamvu la GaN transmitter lomwe lapangidwa limodzi ndi Fraunhofer HHI pamtundu wofananira wa 6G pamwamba pa 70 GHz.Kuchita kwapamwamba kwa gawoli kwatsimikiziridwa ndi Fraunhofer HHI.
Magalimoto odziyimira pawokha, telemedicine, mafakitale odzipangira okha - ntchito zonse zamtsogolo zamayendedwe, chisamaliro chaumoyo ndi mafakitale zimadalira matekinoloje azidziwitso ndi mauthenga omwe amapitilira kuthekera kwa mulingo wamakono wachisanu (5G) wolumikizana ndi mafoni.Kukhazikitsidwa koyembekezeka kwa mauthenga a m'manja a 6G mu 2030 akulonjeza kuti adzapereka maukonde othamanga kwambiri okhudzana ndi mavoti ofunikira m'tsogolomu, ndi chiwerengero cha deta choposa 1 Tbps ndi latency mpaka 100 µs.
Kuyambira 2019 ngati polojekiti ya KONFEKT ("6G Communication Components").
Ofufuzawa apanga ma module opatsirana pogwiritsa ntchito gallium nitride (GaN) mphamvu ya semiconductor, yomwe kwa nthawi yoyamba ingagwiritse ntchito mafupipafupi pafupifupi 80 GHz (E-band) ndi 140 GHz (D-band).Module yaukadaulo ya E-band transmitter, yomwe magwiridwe ake apamwamba adayesedwa bwino ndi Fraunhofer HHI, idzaperekedwa kwa akatswiri pa European Microwave Week (EuMW) ku Milan, Italy, kuyambira 25 mpaka 30 September 2022.
"Chifukwa cha zofunikira kwambiri pa ntchito ndi zogwira mtima, 6G imafuna mitundu yatsopano ya zipangizo," akufotokoza Dr. Michael Mikulla wochokera ku Fraunhofer IAF, yemwe akugwirizanitsa ntchito ya KONFEKT.“Magawo amakono amakono akufika polekezera.Izi zimagwira ntchito makamaka paukadaulo woyambira wa semiconductor, komanso ukadaulo wamagulu ndi mlongoti.Kuti tipeze zotsatira zabwino kwambiri za mphamvu zotulutsa, bandwidth ndi mphamvu zamagetsi, timagwiritsa ntchito GaN-based monolithic integration Microwave Microwave Circuits (MMIC) ya module yathu imalowa m'malo mwa ma circuits a silicon omwe amagwiritsidwa ntchito panopa. , kupereka zotayika zotsika kwambiri komanso zida zophatikizika. Kuphatikiza apo, tikuyenda kutali ndi mapulaneti okwera pamwamba ndi mapulaneti a pulani kuti tipange zomanga zotsika zotsika kwambiri zokhala ndi ma waveguide ndi mabwalo olumikizana omwe amamangidwa.
Fraunhofer HHI amatenga nawo gawo pakuwunika ma waveguide osindikizidwa a 3D.Zigawo zingapo zidapangidwa, kupangidwa ndikuzindikiridwa pogwiritsa ntchito njira yosankha laser melting (SLM), kuphatikiza zogawa mphamvu, tinyanga ndi ma feed a tinyanga.Njirayi imalolanso kupanga zinthu zofulumira komanso zotsika mtengo zomwe sizingapangidwe pogwiritsa ntchito njira zachikale, ndikuyambitsa njira yopangira teknoloji ya 6G.
"Kupyolera mu luso lamakono lamakono, Fraunhofer Institutes IAF ndi HHI amalola Germany ndi Ulaya kutenga sitepe yofunika kwambiri pa tsogolo la mauthenga a m'manja, panthawi imodzimodziyo akupereka chithandizo chofunikira ku ulamuliro waumisiri wa dziko," adatero Mikula.
Module ya E-band imapereka 1W yamphamvu yotulutsa mzere kuchokera ku 81 GHz mpaka 86 GHz pophatikiza mphamvu yotumizira ma module anayi osiyana ndi msonkhano wochepa kwambiri wotayika wa waveguide.Izi zimapangitsa kuti zikhale zoyenera kwa maulalo a data-point-point-point pamtunda wautali, kuthekera kofunikira pakumanga kwamtsogolo kwa 6G.
Kuyesa kosiyanasiyana kopatsirana kwa Fraunhofer HHI kwawonetsa magwiridwe antchito a magawo omwe amapangidwa molumikizana: muzochitika zosiyanasiyana zakunja, ma signature amagwirizana ndi zomwe zikuchitika panopa zachitukuko cha 5G (5G-NR Release 16 of the 3GPP GSM standard).Pa 85 GHz, bandwidth ndi 400 MHz.
Ndi mawonekedwe a mzere, deta imafalitsidwa bwino mpaka mamita 600 mu 64-symbol Quadrature Amplitude Modulation (64-QAM), yopereka mphamvu yapamwamba ya bandwidth ya 6 bps/Hz.Kukula kolakwika kwa siginecha yolandilidwa (EVM) ndi -24.43 dB, pansi pa malire a 3GPP a -20.92 dB.Chifukwa mzere wowonera watsekedwa ndi mitengo ndi magalimoto oyimitsidwa, data yosinthidwa ya 16QAM imatha kufalitsidwa bwino mpaka 150 metres.Deta ya ma Quadrature modulation (quadrature phase shift keying, QPSK) imatha kufalitsidwa ndikulandiridwa bwino pa 2 bps/Hz ngakhale mzere wamaso pakati pa transmitter ndi wolandila watsekedwa kwathunthu.Muzochitika zonse, chiŵerengero chapamwamba cha chizindikiro-ku-phokoso, nthawi zina choposa 20 dB, n'chofunika kwambiri, makamaka poganizira maulendo afupipafupi, ndipo chikhoza kutheka powonjezera ntchito za zigawozo.
Munjira yachiwiri, gawo la transmitter lidapangidwa kuti liziyenda pafupipafupi 140 GHz, kuphatikiza mphamvu yotulutsa yopitilira 100 mW yokhala ndi bandwidth yayikulu ya 20 GHz.Kuyesedwa kwa gawoli kudakali patsogolo.Ma module onsewa ndi magawo abwino opangira ndikuyesa machitidwe amtsogolo a 6G pama frequency a terahertz.
Chonde gwiritsani ntchito fomuyi ngati mukukumana ndi zolakwika za kalembedwe, zolakwika, kapena mukufuna kutumiza pempho kuti musinthe zomwe zili patsambali.Pamafunso ambiri, chonde gwiritsani ntchito fomu yathu yolumikizirana.Kuti mumve zambiri, gwiritsani ntchito gawo lomwe lili pansipa (tsatirani malamulowo).
Ndemanga zanu ndi zofunika kwambiri kwa ife.Komabe, chifukwa cha kuchuluka kwa mauthenga, sitingathe kutsimikizira mayankho a aliyense payekha.
Imelo yanu imagwiritsidwa ntchito podziwitsa omwe akulandirani omwe adatumiza imeloyo.Adilesi yanu kapena adilesi ya wolandila sizigwiritsidwa ntchito pazifukwa zina zilizonse.Zomwe mudalemba ziziwoneka mu imelo yanu ndipo sizisungidwa ndi Tech Xplore mwanjira iliyonse.
Webusaitiyi imagwiritsa ntchito makeke kuti azitha kuyang'ana, kusanthula momwe mumagwiritsira ntchito ntchito zathu, kusonkhanitsa deta kuti mugwirizane ndi zotsatsa zanu, komanso kupereka zinthu kuchokera kwa anthu ena.Pogwiritsa ntchito tsamba lathu la webusayiti, mumavomereza kuti mwawerenga ndikumvetsetsa Mfundo Zazinsinsi ndi Migwirizano yathu.
