Nekutanga kwe5G mukutengeserana, hurukuro dzave dzakawanda munguva pfupi yapfuura. Vaya vanoziva nezve5G vanoziva kuti network dze5G dzinonyanya kushanda pamabhandi maviri efrequency: sub-6GHz uye millimeter waves (Millimeter Waves). Kutaura zvazviri, network dzedu dzeLTE dzazvino dzese dzakavakirwa pa sub-6GHz, nepo tekinoroji ye millimeter wave iri kiyi yekuvhura kugona kwakazara kwenguva ye5G inofungidzirwa. Zvinosuwisa kuti, pasinei nekufambira mberi kwemakumi emakore mukutaurirana kwenharembozha, millimeter waves haisati yapinda muhupenyu hwevanhu nekuda kwezvikonzero zvakasiyana-siyana.
Zvisinei, nyanzvi paBrooklyn 5G Summit muna Kubvumbi dzakataura kuti mafungu eterahertz (Terahertz Waves) anogona kutsiva zvikanganiso zvemafungu e millimeter uye kukurumidzisa kuzadzikiswa kwe6G/7G. Mafungu eTerahertz ane mukana usingaperi.
Muna Kubvumbi, Musangano wechitanhatu weBrooklyn 5G wakaitwa sezvakarongwa, uchifukidza misoro yakaita sekushandiswa kwe5G, zvidzidzo zvakadzidzwa, uye tarisiro yekuvandudzwa kwe5G. Pamusoro pezvo, Purofesa Gerhard Fettweis vekuDresden University of Technology naTed Rappaport, muvambi weNYU Wireless, vakakurukura nezve mukana wemafungu eterahertz pamusangano uyu.
Nyanzvi mbiri idzi dzakati vaongorori vatotanga kudzidza nezvemafungu eterahertz, uye mafrequency awo achava chinhu chakakosha chechizvarwa chinotevera chetekinoroji dzisina waya. Paakataura pamusangano uyu, Fettweis akaongorora zvizvarwa zvekare zvetekinoroji dzekutaurirana nefoni uye akakurukura nezve mukana wemafungu eterahertz mukugadzirisa zvipingamupinyi zve5G. Akataura kuti tava kupinda munguva ye5G, iyo inokosha pakushandiswa kwetekinoroji dzakadai seInternet of Things (IoT) uye augmented reality/virtual reality (AR/VR). Kunyangwe 6G yakafanana zvakanyanya nezvizvarwa zvekare, ichagadzirisawo zvakawanda zvisina kunaka.
Saka, chii chaizvo chinonzi mafungu eterahertz, ayo nyanzvi dzinokoshesa kudaro? Mafungu eTerahertz akataurwa neUnited States muna 2004 uye akanyorwa seimwe ye "Tekinoroji Gumi Dzakanakisisa Dzichachinja Nyika." Mafungu avo anotangira pama micrometer matatu (μm) kusvika 1000 μm, uye mafungu avo anotangira pa300 GHz kusvika pa3 terahertz (THz), akakwirira kupfuura mafungu epamusoro anoshandiswa mu5G, inova 300 GHz yemafungu ema millimeter.
Kubva padhayagiramu iri pamusoro, zvinogona kuonekwa kuti mafungu eterahertz ari pakati pemafungu eredhiyo nemafungu emagetsi, izvo zvinoapa hunhu hwakasiyana kubva kune mamwe mafungu emagetsi kusvika pamwero wakati. Nemamwe mashoko, mafungu eterahertz anosanganisa zvakanakira kutaurirana kwe microwave nekutaurirana kwemagetsi, zvakaita sehuwandu hwekutumira mameseji, kugona kukuru, kutungamira kwakasimba, kuchengetedzeka kwakanyanya, uye kupinda kwakasimba.
Panyaya dzepfungwa, munyaya dzekutaurirana, kana frequency yakakwira, kugona kwekutaurirana kwacho kunowedzera. Kuwanda kwemafungu eterahertz kwakakwira ne1 kusvika ku4 orders yehukuru kupfuura ma microwave ari kushandiswa parizvino, uye kunogona kupa mwero wekutumira data usina waya usingakwanise kuitwa nema microwave. Nokudaro, inogona kugadzirisa dambudziko rekuti kutumira ruzivo kuganhurirwa nebandwidth uye kusangana nezvinodiwa nevashandisi vebandwidth.
Mafungu eTerahertz anotarisirwa kushandiswa muhunyanzvi hwekutaurirana mukati memakore gumi anotevera. Kunyangwe nyanzvi dzakawanda dzichitenda kuti mafungu eTerahertz achachinja indasitiri yekutaurirana, hazvisati zvajeka kuti ndeapi matambudziko chaiwo aanogona kugadzirisa. Izvi zvinodaro nekuti makambani emafoni pasi rese achangotanga network dzavo dze5G, uye zvinotora nguva kuti vaone zvikanganiso.
Zvisinei, hunhu hwemafungu eterahertz hwakatoratidza zvakanakira zvawo. Semuenzaniso, mafungu eterahertz ane marefu mapfupi uye mafrequency akakwira kupfuura mafungu emillimeter. Izvi zvinoreva kuti mafungu eterahertz anogona kutumira data nekukurumidza uye muhuwandu hwakawanda. Nokudaro, kuisa mafungu eterahertz munharembozha kunogona kugadzirisa kusakwana kwe5G mukushandiswa kwedata uye kunonoka.
Fettweis akapawo mhedzisiro yebvunzo panguva yekutaura kwake, zvichiratidza kuti kumhanya kwekutumira kwemafungu eterahertz i1 terabyte pasekondi (TB/s) mukati memamita makumi maviri. Kunyangwe mashandiro aya asina kunyanya kushamisa, Ted Rappaport achiri kutenda zvakasimba kuti mafungu eterahertz ndiwo hwaro hwe6G uye kunyange 7G yeramangwana.
Semunhu akatanga tsvakurudzo yemafungu emamiriyoni, Rappaport akaratidza basa remafungu emamiriyoni muma network e5G. Akabvuma kuti nekuda kwekuwanda kwemafungu eterahertz uye kuvandudzwa kwetekinoroji yemazuva ano yemasero, vanhu vachakurumidza kuona mafoni ane hunyanzvi hwemakombiyuta hwakafanana nehuropi hwemunhu munguva pfupi iri kutevera.
Ehe, kusvika pamwero wakati, zvese izvi zvinongofungidzira zvakanyanya. Asi kana maitiro ekuvandudza akaramba ari sezvaari parizvino, tinogona kutarisira kuona makambani emafoni achishandisa mafungu eterahertz kune tekinoroji yekutaurirana mukati memakore gumi anotevera.
Concept Microwave inyanzvi yekugadzira zvikamu zve5G RF muChina, zvinosanganisira RF lowpass filter, highpass filter, bandpass filter, notch filter/band stop filter, duplexer, Power divider uye directional coupler. Zvese zvinogona kugadziriswa zvichienderana nezvaunoda.
