Poyambitsa 5G pamalonda, zokambirana zambiri zakhala zikuchitika posachedwapa. Omwe amadziwa bwino 5G amadziwa kuti ma network a 5G amagwira ntchito makamaka pa ma frequency band awiri: sub-6GHz ndi millimeter waves (Millimeter Waves). Ndipotu, ma network athu a LTE amakono onse amachokera ku sub-6GHz, pomwe ukadaulo wa millimeter wave ndiye chinsinsi chotsegulira kuthekera konse kwa nthawi yomwe ikuyembekezeredwa ya 5G. Mwatsoka, ngakhale kuti pakhala kupita patsogolo kwa zaka zambiri pakulankhulana pafoni, mafunde a millimeter sanalowe m'miyoyo ya anthu chifukwa cha zifukwa zosiyanasiyana.
Komabe, akatswiri omwe adakumana pa Msonkhano wa Brooklyn 5G mu Epulo adanenanso kuti mafunde a terahertz (Terahertz Waves) angathandize kulimbitsa zofooka za mafunde a millimeter ndikufulumizitsa kukwaniritsidwa kwa 6G/7G. Mafunde a Terahertz ali ndi mphamvu zopanda malire.
Mu Epulo, Msonkhano wachisanu ndi chimodzi wa Brooklyn 5G unachitika monga momwe unakonzedwera, womwe unakhudza mitu monga kukhazikitsidwa kwa 5G, maphunziro omwe aphunziridwa, ndi chiyembekezo cha chitukuko cha 5G. Kuphatikiza apo, Pulofesa Gerhard Fettweis wochokera ku Dresden University of Technology ndi Ted Rappaport, yemwe anayambitsa NYU Wireless, adakambirana za kuthekera kwa mafunde a terahertz pamsonkhanowo.
Akatswiri awiriwa anati ofufuza ayamba kale kuphunzira za mafunde a terahertz, ndipo ma frequency awo adzakhala gawo lofunika kwambiri la mbadwo wotsatira wa ukadaulo wopanda zingwe. Pakulankhula kwake pamsonkhano waukulu, Fettweis adawunikiranso mibadwo yakale ya ukadaulo wolumikizirana pafoni ndikukambirana za kuthekera kwa mafunde a terahertz pothetsa zofooka za 5G. Adanenanso kuti tikulowa mu nthawi ya 5G, yomwe ndi yofunika kwambiri pakugwiritsa ntchito ukadaulo monga Internet of Things (IoT) ndi augmented reality/virtual reality (AR/VR). Ngakhale 6G ili ndi zofanana zambiri ndi mibadwo yakale, idzathetsanso zofooka zambiri.
Ndiye, kodi mafunde a terahertz ndi chiyani kwenikweni, omwe akatswiri amawalemekeza kwambiri? Mafunde a Terahertz adapangidwa ndi United States mu 2004 ndipo adalembedwa ngati amodzi mwa "Maukadaulo Khumi Apamwamba Omwe Adzasintha Dziko Lonse." Kutalika kwa mafunde awo kumayambira pa 3 micrometers (μm) mpaka 1000 μm, ndipo ma frequency awo amayambira pa 300 GHz mpaka 3 terahertz (THz), okwera kuposa ma frequency apamwamba kwambiri omwe amagwiritsidwa ntchito mu 5G, omwe ndi 300 GHz ya mafunde a millimeter.
Kuchokera pachithunzi pamwambapa, zitha kuwoneka kuti mafunde a terahertz ali pakati pa mafunde a wailesi ndi mafunde optical, zomwe zimawapatsa mawonekedwe osiyana ndi mafunde ena a electromagnetic mpaka pamlingo winawake. Mwanjira ina, mafunde a terahertz amaphatikiza zabwino za kulumikizana kwa microwave ndi kulumikizana kwa kuwala, monga kuchuluka kwa ma transmission, mphamvu yayikulu, kulunjika kwamphamvu, chitetezo chapamwamba, ndi kulowa mwamphamvu.
Mwachidziwitso, pankhani yolumikizirana, ma frequency akakwera, mphamvu yolumikizirana imakula. Ma frequency a mafunde a terahertz ndi okwera kwambiri kuposa ma microwave omwe akugwiritsidwa ntchito pano, ndipo amatha kupereka ma frequency osagwiritsa ntchito ma waya omwe ma microwave sangathe kukwaniritsa. Chifukwa chake, imatha kuthetsa vuto la kutumiza chidziwitso chifukwa cha bandwidth ndikukwaniritsa zosowa za ogwiritsa ntchito.
Mafunde a Terahertz akuyembekezeka kugwiritsidwa ntchito muukadaulo wolumikizirana mkati mwa zaka khumi zikubwerazi. Ngakhale akatswiri ambiri amakhulupirira kuti mafunde a terahertz adzasintha kwambiri makampani olumikizirana, sizikudziwikabe kuti ndi zofooka ziti zomwe angathe kuzithetsa. Izi zili choncho chifukwa ogwira ntchito pafoni padziko lonse lapansi angoyambitsa maukonde awo a 5G, ndipo zitenga nthawi kuti azindikire zofooka.
Komabe, makhalidwe enieni a mafunde a terahertz awonetsa kale ubwino wawo. Mwachitsanzo, mafunde a terahertz ali ndi mafunde afupiafupi komanso ma frequency apamwamba kuposa mafunde a millimeter. Izi zikutanthauza kuti mafunde a terahertz amatha kutumiza deta mwachangu komanso mochuluka. Chifukwa chake, kuyambitsa mafunde a terahertz mu ma netiweki am'manja kungathandize kuthana ndi zofooka za 5G pakutulutsa deta komanso kuchedwa.
Fettweis adaperekanso zotsatira za mayeso panthawi yolankhula kwake, zomwe zikusonyeza kuti liwiro lotumizira mafunde a terahertz ndi 1 terabyte pa sekondi (TB/s) mkati mwa mamita 20. Ngakhale kuti magwiridwe antchito awa siabwino kwambiri, Ted Rappaport akadali kukhulupirirabe kuti mafunde a terahertz ndiye maziko a 6G komanso 7G yamtsogolo.
Monga mtsogoleri pa kafukufuku wa mafunde a millimeter, Rappaport watsimikizira udindo wa mafunde a millimeter mu ma network a 5G. Iye wavomereza kuti chifukwa cha kuchuluka kwa mafunde a terahertz komanso kusintha kwa ukadaulo wamakono wa mafoni, anthu posachedwa adzawona mafoni a m'manja okhala ndi luso lowerengera ngati ubongo wa munthu posachedwa.
Zachidziwikire, mpaka pamlingo wina, zonsezi ndi zongopeka kwambiri. Koma ngati chitukukochi chipitirira momwe chilili pano, tingayembekezere kuwona ogwira ntchito pafoni akugwiritsa ntchito mafunde a terahertz paukadaulo wolumikizirana mkati mwa zaka khumi zikubwerazi.
Concept Microwave ndi kampani yopanga zinthu za 5G RF ku China, kuphatikizapo fyuluta ya RF lowpass, fyuluta ya highpass, fyuluta ya bandpass, fyuluta ya notch/band stop, duplexer, Power divider ndi directional coupler. Zonsezi zitha kusinthidwa malinga ndi zomwe mukufuna.
