I te Wiki Ngaruiti o Ūropi (EuMW 2024) i Parī, i whakaatu a Rohde & Schwarz (R&S) i tētahi taunakitanga mō tētahi pūnaha tuku raraunga ahokore 6G e hangai ana ki ngā hononga whakawhitiwhiti terahertz photonic i te Wiki Ngaruiti o Ūropi (EuMW 2024) i Parī, hei āwhina i te whakatairanga i te rohe o ngā hangarau ahokore o te whakatupuranga e whai ake nei. Ko te pūnaha terahertz tino pumau i whakawhanakehia i roto i te kaupapa 6G-ADLANTIK e hangai ana ki te hangarau heru auau, me ngā auau kawe e nui ake ana i te 500GHz.
I te huarahi ki te 6G, he mea nui kia waihangahia ngā pūtake tuku terahertz e whakarato ana i te tohu kounga teitei, ā, ka taea te kapi i te whānuitanga o te auau. Ko te whakakotahi i te hangarau whatu me te hangarau hiko tētahi o ngā huarahi hei whakatutuki i tēnei whāinga ā muri ake nei. I te huihuinga EuMW 2024 i Parī, ka whakaatu a R&S i tana takoha ki te rangahau terahertz hou i roto i te kaupapa 6G-ADLANTIK. Ka arotahi te kaupapa ki te whakawhanake i ngā wāhanga whānuitanga auau terahertz i runga i te whakaurunga o ngā photon me ngā irahiko. Ka taea te whakamahi i ēnei wāhanga terahertz kāore anō kia whakawhanakehia mō ngā inenga auaha me te whakawhiti raraunga tere ake. Ka taea te whakamahi i ēnei wāhanga ehara i te mea mō te whakawhitiwhiti kōrero 6G anake, engari mō te kite me te whakaahua hoki.
Ko te kaupapa 6G-ADLANTIK e tautokona ana e te Manatū Mātauranga me te Rangahau ā-Motu o Tiamana (BMBF) me te whakahaeretia e R&S. Ko ngā hoa mahi ko TOPTICA Photonics AG, Fraunhofer-Institut HHI, Microwave Photonics GmbH, Technical University of Berlin me Spinner GmbH.
He pūnaha terahertz tino pumau 6G e hangai ana ki te hangarau photon
Ko te Whakaaturanga-o-te-Aroha e whakaatu ana i tētahi pūnaha terahertz tino pumau, ka taea te whakarerekē mō te tuku raraunga ahokore 6G i runga i ngā whakaranu terahertz photonic e whakaputa ana i ngā tohu terahertz i runga i te hangarau heru auau. I roto i tēnei pūnaha, ka huri pai te photodiode i ngā tohu patu whatu i hangaia e ngā laser me ngā auau whatu rerekē hei tohu hiko mā te tukanga whakaranu photon. Ko te hanganga pūihi huri noa i te whakaranu photoelectric ka huri i te au whakaahua hurihuri hei ngaru terahertz. Ka taea te whakarerekē me te tango i te tohu hua mō te whakawhitiwhiti ahokore 6G, ā, ka taea te whakarerekē ngāwari i runga i te whānuitanga o te auau. Ka taea hoki te whakawhānui i te pūnaha ki ngā inenga wāhanga mā te whakamahi i ngā tohu terahertz kua whiwhihia kia ōrite. Ko te whakatauira me te hoahoa o ngā hanganga arataki ngaru terahertz me te whakawhanaketanga o ngā oscillator tohutoro photonic haruru tino iti kei roto hoki i ngā wāhanga mahi o te kaupapa.
Nā te pūnaha hanga auau whatu raka-here (OFS) i roto i te miihini taiaho TOPTICA te haruru tino iti o te pūnaha. He wāhanga nui o tēnei pūnaha ngā taputapu matatau a R&S: Ka hangaia e te kaihanga tohu whārite IF whānui R&S SFI100A he tohu whārite turanga mō te whakarerekētanga whatu me te tere tauira o te 16GS/s. Ka hangaia e te kaihanga tohu RF me te ngaruiti R&S SMA100B he tohu karaka tohutoro pumau mō ngā pūnaha TOPTICA OFS. Ka tangohia e te oscilloscope R&S RTP te tohu whārite turanga i muri i te kaiwhiwhi terahertz ngaru tonu (cw) whakaahua (Rx) i te tere tauira o te 40 GS/s hei tukatuka me te tango i te tohu auau kawe 300 GHz.
6G me ngā whakaritenga mō te roopu auau ā muri ake nei
Ka kawea mai e te 6G ngā āhuatanga tono hou ki te ahumahi, ki te hangarau hauora me te oranga o ia rā. Ka whakatakotohia e ngā tono pēnei i te metacomes me te Extended Reality (XR) he tono hou ki runga i te latency me ngā tere whakawhiti raraunga kāore e taea e ngā pūnaha whakawhitiwhiti kōrero o nāianei. Ahakoa kua tautuhia e te International Telecommunication Union's World Radio Conference 2023 (WRC23) ngā roopu hou i roto i te whānuitanga FR3 (7.125-24 GHz) hei rangahau atu mō ngā whatunga 6G arumoni tuatahi ka whakarewahia i te tau 2030, Engari kia tutuki ai te pūmanawa katoa o te mooni mariko (VR), te mooni whakanuia (AR) me ngā tono mooni whakauru (MR), ka tino hiahiatia hoki te roopu Hertz Āhia-Moananui-a-Kiwa tae atu ki te 300 GHz.
