Nubwo 4G yahawe uruhushya mu Bushinwa, kubaka imiyoboro minini byatangiye.Guhura nubwiyongere bukabije bwamakuru yimikorere, birakenewe guhora tunoza ubushobozi bwurusobe nubwiza bwubwubatsi.Nyamara, ikwirakwizwa rya 4G inshuro nyinshi, kwiyongera kwivanga, hamwe no gukenera gusangira urubuga na sitasiyo fatizo ya 2G na 3G bitera iterambere rya antenne ya sitasiyo ya sitasiyo yerekeza ku cyerekezo cyo kwishyira hamwe, kwaguka kwagutse no guhinduka byoroshye.
Ubushobozi bwo gukwirakwiza imiyoboro ya 4G.
Urusobe rwiza rwo gukwirakwiza urwego hamwe nubunini runaka bwubushobozi ni urwego rwibanze rwo kumenya ubuziranenge bwurusobe.
Umuyoboro mushya wigihugu ugomba gutekereza ku iyubakwa ryurwego rwubushobozi mugihe urangije intego yo gukwirakwiza.Umuyobozi w’igurisha ry’ishoramari ry’Ubushinwa mu ishami ry’ubucuruzi ridafite insinga za CommScope, Wang Sheng, yabwiye Ubushinwa ati: "Muri rusange, hari inzira eshatu gusa zo kuzamura ubushobozi bw’urusobe."
Imwe ni ugukoresha imirongo myinshi kugirango umurongo mugari waguke.Kurugero, GSM yabanje kugira 900MHz gusa.Nyuma, abakoresha bariyongereye kandi 1800MHz inshuro zongerewe.Ubu imirongo ya 3G na 4G ni nyinshi.Ubushinwa bwa Mobile-TDE LTE ifite imirongo itatu, kandi hakoreshejwe inshuro ya 2.6GHz.Abantu bamwe mu nganda bemeza ko iyi ari yo mipaka, kubera ko kwihuta kwinshi bizagenda birushaho gukomera, kandi ibyinjira n’ibisohoka mu bikoresho ntibigereranijwe.Iya kabiri ni ukongera umubare wibibanza fatizo, nuburyo bukoreshwa cyane.Kugeza ubu, ubucucike bwa sitasiyo fatizo mu mijyi minini nini nini yagabanutse kuva ku kigereranyo cya sitasiyo imwe fatizo kuri kilometero kugera kuri sitasiyo imwe ya metero 200-300.Icya gatatu ni ukunoza imikorere ya spekure, nicyerekezo cya buri gisekuru cyikoranabuhanga ryitumanaho rigendanwa.Kugeza ubu, imikorere ya 4G ni yo hejuru, kandi igeze ku gipimo cya 100m muri Shanghai.
Kugira urusobe rwiza hamwe nubunini runaka bwubushobozi ni urufatiro rwingenzi rwurusobe.Ikigaragara ni uko Ubushinwa Mobile buhagaze kuri TD-LTE ni ugushiraho umuyoboro wo mu rwego rwo hejuru kandi ugahagarara hejuru yisoko rya 4G hamwe nuburambe bwiza bwabakoresha."Twagize uruhare mu iyubakwa ry’imiyoboro 240 LTE ku isi.""Duhereye ku bunararibonye bwa CommScope, hari ibintu bitanu mu iyubakwa ry'urusobe rwa LTE. Icya mbere ni ugucunga urusaku rw'urusobe; icya kabiri ni ugutegura no kugenzura urwego rutagira umugozi; icya gatatu ni ukuvugurura umuyoboro; icya kane ni ugukora a akazi keza mubimenyetso byo kugaruka, ni ukuvuga, umurongo wa signal ya uplink na signal ya downlink igomba kuba yagutse bihagije; icya gatanu nugukora akazi keza ko gukingira mu nzu no gukwirakwiza munsi yibidukikije bidasanzwe.
Ibisobanuro bya tekiniki yikizamini cyo gucunga urusaku.
Nibibazo byukuri gucunga urwego rwurusaku no gutuma abakoresha umuyoboro wurubuga bafite uburyo bwihuse.
Bitandukanye no kongera ibimenyetso bya 3G mukongera imbaraga zo kohereza, umuyoboro wa 4G uzazana urusaku rushya hamwe no kongera ibimenyetso."Ikiranga umuyoboro wa 4G ni uko urusaku rutagira ingaruka ku murenge utwikiriwe na antene gusa, ahubwo runagira ingaruka ku mirenge ikikije iyo. igipimo cyo kohereza amakuru kiragabanuka, uburambe bw’abakoresha buragabanuka, kandi amafaranga yinjira aragabanuka. "Wang Sheng yagize ati: "uko umuyoboro wa 4G ugenda uva kuri sitasiyo fatizo, ni nako igipimo cy’amakuru kiba kiri hasi, kandi n’uko umuyoboro wa 4G wegera imiyoboro, niko abakoresha benshi bashobora kubona. Tugomba gucunga urwego rw’urusaku, bityo ko umuyoboro ushobora kubona uburyo bwihuse, nicyo kibazo dukeneye rwose kugikemura. "Kugira ngo iki kibazo gikemuke, hari byinshi bisabwa: icya mbere, umurongo wigice cya RF ugomba kuba mugari bihagije;icya kabiri, ibikoresho byimikorere ya radio yumurongo wose bigomba kuba byiza bihagije;icya gatatu, umurongo wa signal ya uplink yagarutse igomba kuba yagutse bihagije.
Mumuyoboro gakondo wa 2G, urusobekerane rwurusobekerane rwimikorere ya selile yegeranye ni nini cyane.Terefone igendanwa irashobora kwakira ibimenyetso biva kuri sitasiyo zitandukanye.Terefone zigendanwa 2G zizahita zifunga kuri sitasiyo fatizo hamwe nikimenyetso gikomeye, wirengagize abandi.Kuberako idahinduka kenshi, ntabwo bizatera intambamyi kuri selile ikurikira.Kubwibyo, murusobe rwa GSM, hari 9 kugeza 12 byuzuzanya bishobora kwihanganira.Ariko, mugihe cya 3G, gukwirakwiza kumurongo bizagira ingaruka zikomeye kubushobozi bwo gutunganya sisitemu.Noneho, antenne ifite dogere 65 ya horizontal igice cyakoreshejwe murwego rwo gukwirakwiza imirenge itatu.Imirenge itatu ikwirakwiza LTE ikenera antenne ikora cyane kugirango ikorwe kimwe na 3G."Icyitwa antenne ikora cyane bivuze ko mugihe ukora antenne ya dogere 65, ubwishingizi kumpande zombi zurusobe bigabanuka vuba cyane, bigatuma agace kegeranye hagati yimiyoboro iba nto. Kubwibyo, dushobora kubona neza ko imiyoboro ya LTE ifite hejuru kandi ibisabwa cyane ku bikoresho. "Wang Sheng ati.
Igabana rya Frequency yigenga amashanyarazi aringaniza antenna iragenda iba ngombwa.
Birakenewe kugenzura inkombe ya rezo yumurongo neza kugirango ugabanye interineti.Inzira nziza ni ukumenya antenne igenzura.
Gukemura ikibazo cyo kugenzura imiyoboro, ahanini biterwa nibintu byinshi: icya mbere, igenamigambi ryurusobe, hasigara intera ihagije muri frequency;icya kabiri, urwego rwibikoresho, buri gikorwa cyubwubatsi kigomba kugenzurwa neza;gatatu, urwego rwo kwishyiriraho."Twinjiye mu Bushinwa mu 1997 kandi dukora imanza nyinshi zifatika. Muri kaminuza ya Andrew, izobereye muri antene, tuzakora imyitozo yo kubigisha gushyira no gukoresha ibicuruzwa byacu bidafite insinga. Muri icyo gihe, dufite n'itsinda kora umuhuza na antene. "" Ibicuruzwa bidafite insinga, cyane cyane ibicuruzwa byo hanze, bifite aho bikorera cyane muri sisitemu y’itumanaho yose, ihura n’umuyaga, izuba, imvura, ubushyuhe bwinshi nubushyuhe buke, bityo ibisabwa kuri byo ni byinshi cyane."Ibicuruzwa byacu birashobora guhagarara aho imyaka 10 kugeza 30. Ntabwo rwose byoroshye."Wang Sheng ati.
