Ndi kukhazikitsidwa kwa malonda kwa 5G, zokambirana za izo zachuluka posachedwa. Iwo omwe amadziwa 5G amadziwa kuti maukonde a 5G amagwira ntchito pamagulu awiri a frequency: sub-6GHz ndi mafunde a millimeter (Millimeter Waves). M'malo mwake, maukonde athu amakono a LTE onse amachokera ku sub-6GHz, pomwe ukadaulo wa millimeter wave ndiye chinsinsi chotsegula kuthekera konse kwanthawi yomwe 5G ikuyembekezeredwa. Tsoka ilo, ngakhale kwazaka zambiri zakupita patsogolo kwa kulumikizana kwa mafoni, mafunde a millimeter sanalowebe m'miyoyo ya anthu chifukwa cha zifukwa zosiyanasiyana.
Komabe, akatswiri ku Brooklyn 5G Summit mu Epulo adati mafunde a terahertz (Terahertz Waves) atha kubweza zofooka za mafunde a millimeter ndikufulumizitsa kukwaniritsidwa kwa 6G/7G. Mafunde a Terahertz ali ndi mphamvu zopanda malire.
M'mwezi wa Epulo, Msonkhano wa 6 ku Brooklyn 5G udachitika monga momwe udakonzedwera, womwe umafotokoza mitu monga kutumizidwa kwa 5G, maphunziro omwe aphunziridwa, komanso momwe akutukula 5G. Kuonjezera apo, Pulofesa Gerhard Fettweis wochokera ku Dresden University of Technology ndi Ted Rappaport, yemwe anayambitsa NYU Wireless, adakambirana za kuthekera kwa mafunde a terahertz pamsonkhano.
Akatswiri awiriwa adanena kuti ofufuza ayamba kale kuphunzira mafunde a terahertz, ndipo ma frequency awo adzakhala gawo lofunikira kwambiri pamibadwo yotsatira yaukadaulo wopanda zingwe. Pakulankhula kwake pamsonkhano, Fettweis adawunikiranso mibadwo yam'mbuyomu yaukadaulo wolumikizana ndi mafoni ndikukambirana za kuthekera kwa mafunde a terahertz pothana ndi zolephera za 5G. Ananenanso kuti tikulowa mu nthawi ya 5G, yomwe ndi yofunika kwambiri pakugwiritsa ntchito matekinoloje monga Internet of Things (IoT) ndi augmented real/virtual real (AR/VR). Ngakhale 6G imagawana zofanana zambiri ndi mibadwo yam'mbuyo, idzathetsanso zofooka zambiri.
Ndiye, kodi mafunde a terahertz, omwe akatswiri amawalemekeza kwambiri chonchi? Mafunde a Terahertz adanenedwa ndi United States mu 2004 ndipo adatchulidwa kuti ndi imodzi mwa "Makina Opambana Khumi Amene Adzasintha Dziko Lapansi." Kutalika kwawo kumayambira 3 ma micrometer (μm) mpaka 1000 μm, ndipo ma frequency awo amachokera ku 300 GHz mpaka 3 terahertz (THz), apamwamba kuposa ma frequency apamwamba kwambiri omwe amagwiritsidwa ntchito mu 5G, omwe ndi 300 GHz pamafunde a millimeter.
Kuchokera pa chithunzi pamwambapa, zitha kuwoneka kuti mafunde a terahertz ali pakati pa mafunde a wailesi ndi mafunde owoneka, omwe amawapatsa mawonekedwe osiyanasiyana ndi mafunde ena amagetsi mpaka pamlingo wina. Mwa kuyankhula kwina, mafunde a terahertz amaphatikiza ubwino wa kulankhulana kwa microwave ndi kulankhulana kwa kuwala, monga maulendo othamanga kwambiri, mphamvu zazikulu, mayendedwe amphamvu, chitetezo chapamwamba, ndi kulowa mwamphamvu.
Mwachidziwitso, m'munda wolankhulana, kuwonjezereka kwafupipafupi, ndikokulirapo kwa mphamvu yolankhulirana. Kuchuluka kwa mafunde a terahertz ndi 1 mpaka 4 kuyitanitsa kwakukulu kuposa ma microwave omwe amagwiritsidwa ntchito pano, ndipo atha kupereka mitengo yotumizira opanda zingwe yomwe ma microwave sangathe kukwaniritsa. Chifukwa chake, imatha kuthana ndi vuto la kufalitsa chidziwitso kukhala lochepa ndi bandwidth ndikukwaniritsa zofuna za ogwiritsa ntchito.
Mafunde a Terahertz akuyembekezeka kugwiritsidwa ntchito muukadaulo wolumikizirana mkati mwazaka khumi zikubwerazi. Ngakhale akatswiri ambiri amakhulupirira kuti mafunde a terahertz asintha njira yolumikizirana, sizikudziwikabe kuti ndi zofooka ziti zomwe angathane nazo. Izi ndichifukwa choti ogwiritsa ntchito mafoni padziko lonse lapansi angoyambitsa ma network awo a 5G, ndipo zitenga nthawi kuti azindikire zofooka.
Komabe, mawonekedwe akuthupi a mafunde a terahertz adawunikira kale zabwino zawo. Mwachitsanzo, mafunde a terahertz ali ndi utali waufupi komanso mafunde apamwamba kuposa mafunde a millimeter. Izi zikutanthauza kuti mafunde a terahertz amatha kufalitsa deta mwachangu komanso mokulirapo. Chifukwa chake, kuyambitsa mafunde a terahertz mumanetiweki am'manja kumatha kuthana ndi zofooka za 5G pakutulutsa kwa data ndi latency.
Fettweis adaperekanso zotsatira za mayeso pakulankhula kwake, kuwonetsa kuti kuthamanga kwa mafunde a terahertz ndi 1 terabyte pamphindi (TB / s) mkati mwa 20 metres. Ngakhale izi sizowoneka bwino, Ted Rappaport akukhulupirirabe kuti mafunde a terahertz ndiye maziko a mtsogolo 6G komanso 7G.
Monga mpainiya pantchito yofufuza ma millimeter wave, Rappaport yatsimikizira gawo la mafunde a millimeter mu maukonde a 5G. Iye adavomereza kuti chifukwa cha kuchuluka kwa mafunde a terahertz komanso kusintha kwa matekinoloje amakono amakono, anthu posachedwapa adzawona mafoni a m'manja omwe ali ndi makompyuta ofanana ndi ubongo waumunthu posachedwa.
Inde, kumlingo wina, zonsezi ndi zongopeka kwambiri. Koma ngati chitukuko chikupitilira monga momwe zilili pano, titha kuyembekezera kuwona ogwiritsa ntchito mafoni akugwiritsa ntchito mafunde a terahertz paukadaulo wolumikizirana mkati mwazaka khumi zikubwerazi.
Concept Microwave ndi katswiri wopanga zida za 5G RF ku China, kuphatikiza fyuluta ya RF lowpass, fyuluta ya highpass, fyuluta ya bandpass, fyuluta ya notch/band stop fyuluta, duplexer, Power divider ndi directional coupler. Onse a iwo akhoza makonda malinga ndi zofuna zanu.
