Sisitimu Yekutaurirana Nenharembozha
Masisitimu ekutaurirana nefoni ave nekushanduka kukuru kubva pakatanga kushandiswa. Masisitimu aya anobvumira vashandisi kutaurirana vachishandisa nharembozha dzine ruzivo rwakakura uye kufamba kwakanyanya. Chinyorwa chino chichatsanangura zvakadzama tsananguro, zvikamu, tekinoroji, kushanduka, mabhenefiti, matambudziko, uye remangwana remasisitimu ekutaurirana nefoni.
Kunzwisisa Masisitimu Ekutaurirana Nefoni
Sisitimu yekutaurirana nefoni inetwork yekutaurirana inobvumira vashandisi vemafoni (senge mafoni) kutaurirana, kungave kuburikidza nekufona nezwi, mameseji, kana data reinternet. Sisitimu iyi inoshandisa nhevedzano yenharembozha dzinotumira nekugamuchira dzinonzi base stations, dzakapararira munzvimbo dzakasiyana siyana kugadzira nzvimbo yakakura yekufukidza. Vashandisi vanogona kufamba kubva panzvimbo imwe kuenda kune imwe vasina kurasikirwa nekubatana, nekuda kwetekinoroji yekutumirana iri musystem yemafoni.
Zvikamu zveSisitimu dzeKutaurirana dzeNharembozha
Sisitimu yekutaurirana nefoni ine zvikamu zvikuru zvakati wandei:
1. Nhare Yekufambisa (MS): Ichi chishandiso chinoshandiswa nevashandisi vekupedzisira, senge nharembozha kana tablet.
2. Base Station Subsystem (BSS): Ine Base Transceiver Station (BTS) uye Base Station Controller (BSC) iyo inoshanda kudzora kutaurirana pakati penharembozha nenetwork.
3. Network Switching Subsystem (NSS): Inosanganisira hardware nesoftware inotarisira mafoni nedata, kusanganisira Mobile Switching Center (MSC), Home Location Register (HLR), Visitor Location Register (VLR), nezvimwewo.
4. Sisitimu yeKushanda neKutsigira (OSS): Ine basa rekutarisira network nekupa rutsigiro rwekugadzirisa nekushanda.
5. Network yekutumira: Network inotsigira data uye kutakura masaini pakati peBSS, NSS, neOSS.
Tekinoroji muNharembozha dzeKutaurirana
Nekufamba kwenguva, tekinoroji inoshandiswa mumafoni yakavandudzwawo. Ruzhinji rwehunyanzvi uhwu runogona kukamurwa kuita zvizvarwa zvakasiyana-siyana, chimwe nechimwe chichiratidzwa nekufambira mberi kukuru.
1G (Chizvarwa Chekutanga)
Chizvarwa chekutanga chemafoni ekutaurirana chaishandisa tekinoroji yeanalog. 1G yaigonesa mafoni ezwi asi yaive nemiganho maererano nemhando yezwi uye kugona kwenetwork. Muenzaniso wetekinoroji ye1G iAMPS (Advanced Mobile Phone System).
2G (Chizvarwa Chechipiri)
Chizvarwa chechipiri chakaunza tekinoroji yedhijitari, zvichiita kuti kutumira mameseji (SMS) uye kutumira data rekutanga. GSM (Global System for Mobile Communications) neCDMA (Code Division Multiple Access) mienzaniso yetekinoroji ye2G. Zvakanakira zvavo zvinosanganisira kuchengetedzeka kuri nani uye kushanda zvakanaka kwe spectrum zvichienzaniswa ne1G.
3G (Chizvarwa Chechitatu)
Yakatangwa kutanga kwema2000, 3G yakagonesa kutumira data nekukurumidza, kufona kwevhidhiyo kunotsigirwa, uye kuvandudzwa kweinternet. Tekinoroji dzakadai seUMTS (Universal Mobile Telecommunications System) neCDMA2000 mienzaniso ye3G. Kumhanya kunosvika mamegabits akati wandei pasekondi.
4G (Chizvarwa Chechina)
4G inopa kumhanya kwakanyanya uye kunonoka kwakaderera kupfuura 3G. Tekinoroji yeLTE (Long-Term Evolution) muenzaniso wakanaka we4G, inobvumira kuratidzwa kwevhidhiyo yemhando yepamusoro, mitambo yepamhepo, uye mamwe maapplication anoshandisa data rakawanda. Kumhanya kwekudhawunirodha kunogona kusvika mazana emamegabits pasekondi.
5G (Chizvarwa Chechishanu)
Chigadzirwa chitsva ichi, 5G, chinopa kumhanya kwakanyanya, kunonoka kwakanyanya, uye kubatana kwakavimbika. Iyi tekinoroji ine mukana wekushandura maindasitiri akasiyana-siyana nekutsigira mashandisirwo akadai se virtual reality (VR), augmented reality (AR), Internet of Things (IoT), uye mota dzinozvitonga. Kumhanya kwe5G kunogona kusvika gigabits pasekondi.
Kushanduka kweSisitimu dzeKutaurirana dzeNharembozha
Masisitimu ekutaurirana nefoni akachinja nekukurumidza:
1. Kushandiswa kwe1G: Yakatanga kuma1980 nehunyanzvi hweanalog.
2. Kuvandudzwa kwe2G: Kutangwa kwekushandiswa kwedhijitari muma1990, kwakagonesa kushandiswa kwemeseji uye kunaka kwekufona kwakavandudzika.
3. Kuchinja kuenda ku3G: Mukutanga kwema2000, kumhanya kwekutumira data kwakabvumira kuti internet iwanikwe zviri nani.
4. Kugadzirwa kwe4G: Yakatangwa mukupera kwema2000 nekutanga kwema2010, nekuvandudzika kukuru mukumhanya kweinternet uye kunaka kwebasa.
5. Kushandiswa kwe5G: Kutanga mukupera kwema2010 kusvika pari zvino, zvichiunza tekinoroji yemafoni munguva itsva nekukurumidza kunoshamisa uye kunonoka kushoma.
Mabhenefiti eSisitimu dzeKutaurirana neNharembozha
Masisitimu ekutaurirana nefoni anopa mabhenefiti akasiyana-siyana munharaunda uye mumaindasitiri akasiyana-siyana:
1. Kutaurirana Kuri Nyore Uye Kuchinjika: Kunobvumira kutaurirana chero nguva uye chero kupi pasina kusungwa netambo.
2. Kuwana Internet: Inopa mukana wekuwana internet nekukurumidza uye kwakavimbika, inotsigira basa, kudzidza uye varaidzo.
3. Mabasa eEmergency: Ipai zvivakwa zvemabasa eEmergency ari nyore kuwana.
4. Kuwedzera Kushanda Kwebhizinesi: Zvinoita kuti mabhizinesi arambe akabatana uye atarisire mashandiro avo zviri nani.
5. Kugadzira Zvinhu Zvitsva muDhijitari: Kutungamira mukugadzira zvinhu zvitsva munzvimbo dzakadai seIoT, otomatiki, uye tekinoroji yakangwara.
Matambudziko muNharembozha dzeKutaurirana
Pasinei nemabhenefiti ayo akawanda, masisitimu ekutaurirana nefoni anosanganawo nematambudziko akasiyana-siyana:
1. Kugona Kwenetiweki: Kuwedzera kwekudiwa kwedata kunoda kugona kukuru kwenetiweki.
2. Kuchengetedzwa uye Ruzivo: Zvipingamupinyi zvekuchengetedzwa kwepaindaneti uye ruzivo rwevashandisi zvinofanirwa kutarisirwa zvakakomba.
3. Zvivakwa: Kugadzira zvivakwa zvitsva kunoda mari yakawanda, kunyanya kune matekinoroji epamusoro akadai se5G.
4. Mutemo neSpectrum: Zvipingamupinyi maererano nemutemo uye kugoverwa kwema frequency spectrum zvinogonawo kukanganisa kukura.
5. Kukanganisa Masaini: Simba rezvinhu zvinokanganisa kutaurirana rinokanganisa kunaka kwekutaurirana.
Remangwana reMasisitimu Ekukurukurirana Kwenharembozha
Remangwana remasisitimu ekutaurirana nefoni rinonakidza zvikuru nekuwedzera kwekushandiswa kwe5G:
1. Kubatana Kwakavandudzwa: Midziyo yakawanda inogona kubatana netiweki yakavimbika.
2. Kuvandudzwa kweTekinoroji: Kushandisa AI (Artificial Intelligence) uye ML (Machine Learning) kuwedzera kushanda zvakanaka kwenetwork.
3. IoT Ecosystem: Kugadzirwa kweIoT ecosystem yakasimba ine mashandisirwo mudzimba dzakangwara, maguta akangwara, uye indasitiri 4.0.
4. Mota Dzinozvimirira: Rutsigiro rwekutaurirana runodiwa pakushanda kwemota dzinozvimirira.
5. Ruzivo rweMushandisi: Ruzivo rwuri nani rwemushandisi neVR neAR zvakavandudzwa.
Mhedziso
Masisitimu ekutaurirana nefoni akachinja nzira yatinotaurirana uye yatinotaura nayo. Kushanduka kwavo kubva pa1G kuenda ku5G kwakaratidza kuvandudzwa kukuru mukumhanya, mhando, uye kugona kwebasa. Pasinei nekutarisana nematambudziko akasiyana-siyana, ramangwana ravo rine tariro, nekuvandudzwa kwetekinoroji kuri kuramba kuchipa mipiro yakakosha kuzvinhu zvakasiyana-siyana zvehupenyu neindasitiri. Nekutsigirwa kuri kuramba kuripo muzvivakwa nemirau, masisitimu ekutaurirana nefoni acharamba ari mbiru huru yetekinoroji yepasi rose.
