5G chizvarwa chechishanu chewaya isina waya.Vashandisi vanozozviziva seimwe yeanokurumidza, akasimba matekinoroji ati amboonekwa nenyika.Izvi zvinoreva kukurumidza kudhawunirodha, kuderera zvakanyanya, uye kukosha kwakakosha pamararamiro atinoita, kushanda, uye kutamba.
Nekudaro, mukati mepasi pevhu, kune zvitima zvepasi pevhu mumugero.Kuona mavhidhiyo mapfupi pafoni yako inzira yakanaka yekuzorora muchitima chepasi pevhu.Ko 5G inovhara sei uye inoshanda pasi pevhu?
Zvichienderana nezvinodiwa zvakafanana, kufukidzwa kwe5G metro inyaya yakakosha kune vanobata Telecommunication.
Saka, 5G inoshanda sei pasi pevhu?
Metro chiteshi chakaenzana neyakawanda-yepasi pasi, uye inogona kugadziriswa zviri nyore neyakajairwa Mu-kuvaka mhinduro kana nyowani inoshanda Yakagoverwa antenna masisitimu nevashandisi.Mumwe nemumwe anoshanda ane chirongwa chakakura kwazvo.Chinhu chimwe chete ndechekuisa sezvakagadzirwa.
Naizvozvo, mugero wakareba wepasi pevhu ndiyo inotarisa kuvharika kwe subway.
Metro tunnels kazhinji anopfuura 1,000 metres, achiperekedzwa nhete uye mabhende.Kana ukashandisa antenna inotungamira, chiratidzo chemafuro idiki, kudzoreredza kungave nekukurumidza, uye zviri nyore kuvharika.
Kuti ugadzirise matambudziko aya, masaini masaini anofanirwa kuburitswa zvakafanana munzira yenzira kuti igadzire mutsara wechiratidzo chekuvhara, iyo yakasiyana chaizvo neiyo-matatu-chikamu kufukidzwa kwepasi macro station.Izvi zvinoda antenna yakakosha: tambo inodonha.
Kazhinji, tambo dzeredhiyo-frequency, dzinozivikanwa sevanodyisa, dzinobvumira chiratidzo kuti chifambe mukati metambo yakavharwa, kwete chete haigone kuburitsa chiratidzo, asi kurasikirwa kwekutapurirana kunogona kuve kudiki sezvinobvira.Kuti chiratidzo chifambiswe zvakanaka kubva kuchikamu chiri kure kuenda kune antenna, ipapo masaisai eredhiyo anogona kufambiswa zvakanaka kuburikidza neantenna.
Kune rumwe rutivi, tambo inodonha yakasiyana.Tambo inobvinza haina kudzivirirwa zvizere.Iyo ine yakaenzana yakagovaniswa leakage slot, ndiko kuti, inovuza tambo senge nhevedzano yediki slots, inobvumira iyo chiratidzo kuti iburitse kunze zvakaenzana kuburikidza neinotsvedza.
Kana mbozha mbozha yangogashira masaini, masaini anogona kutumirwa kuburikidza neiyo slots kusvika mukati metambo uye obva aendeswa kuBase Station.Izvi zvinobvumira nzira mbiri dzekutaura, dzakagadzirirwa-zvakagadzirirwa mamiriro emutsara senge metro tunnel, izvo zvakafanana nekushandura echinyakare magirobhu kuita machubhu marefu efluorescent.
Metro tunnel yekuvhara inogona kugadziriswa netambo dzinobuda, asi pane nyaya dzinoda kugadziriswa nevashandisi.
Kushandira vashandisi vavo, vese vashandisi vanofanirwa kuita metro chiratidzo chekuvhara.Tichipihwa nzvimbo shoma yemugero, kana mushandisi wega wega achivaka seti yemidziyo, inogona kunge iri tsvina uye yakaoma.Saka zvinodikanwa kugovera tambo dziri kubuda uye kushandisa mudziyo unosanganisa akasiyana spectrum kubva kune akasiyana maoperator uye woatumira mutambo inodonha.
Chishandiso ichi, chinosanganisa masaini uye zviratidziro kubva kune vakasiyana-siyana, chinonzi Point of Interface (POI) Combiner.Combiners ane zvakanakira kusanganisa akawanda-masaini uye yakaderera yekuisa kurasikirwa.Inoshanda kune hurongwa hwekutaurirana.
Mumufananidzo unotevera unoratidza, musanganiswa wePOI ane akati wandei madoko.Inogona kusanganisa zviri nyore 900MHz, 1800MHz, 2100MHz, uye 2600MHz uye mamwe ma frequency.
Kutanga kubva ku3G, MIMO yakapinda padanho rekufambiswa kwenharembozha, ikava nzira yakakosha yekuwedzera system kugona;ne4G, 2 * 2MIMO yave chiyero, 4 * 4MIMO yakakwirira;kusvika 5G nguva, 4 * 4 MIMO yave chiyero, yakawanda mbozha nhare inogona kutsigira.
Naizvozvo, metro tunnel yekuvhara inofanirwa kutsigira 4 * 4MIMO.Nekuda kwechiteshi chega chega cheMIMO system inoda yakazvimirira antenna, iyo tunnel yekuvhara inoda tambo ina dzakafanana dzinovuza kuti uwane 4 * 4MIMO.
Sezvinoratidzwa nemufananidzo unotevera: 5G iri kure unit sechiratidzo chechiratidzo, inoburitsa zviratidzo zve 4, iyo inovabatanidza nezviratidzo zvevamwe vashandisi kuburikidza nePOI musanganisi, uye inovadyisa mu 4 parallel leaky cables, inowana iyo yakawanda-channel mbiri mbiri. .iyi ndiyo nzira yakananga uye inoshanda yekuwedzera system kugona.
Nekuda kwekumhanya kwakanyanya kwe subway, kunyangwe kudonha kwetambo kuvharidzira chirango mumutsara, nharembozha dzinowanzo kuchinjika uye kusarudzwa patsva pamubatanidzwa wechirongwa.
Kugadzirisa dambudziko iri, rinogona kubatanidza nharaunda dzinoverengeka kuita nharaunda huru, zvine musoro ndeye nharaunda imwe chete, nekudaro ichiwedzera kakati wandei kwekuvharirwa kwenharaunda imwe.Iwe unogona kudzivirira kuchinja uye kusarudzazve kakawanda, asi huwandu hwakaderedzwa zvakare, hunokodzera nzvimbo dzakaderera dzekutaurirana traffic.
Nekuda kweshanduko yenharembozha, tinogona kunakidzwa nenharembozha chero nguva, chero kupi, kunyangwe pakadzika pasi pevhu.
Mune ramangwana, zvese zvichashandurwa ne5G.Kumhanya kwekuchinja kwehunyanzvi mumakumi emakore apfuura kwave nekukurumidza.Chinhu chimwe chete chatinoziva ndechekuti, mune ramangwana, zvichange zvichinyanya kukurumidza.Tichaona shanduko yetekinoroji inoshandura vanhu, mabhizinesi, uye nzanga yese.
