Masisitimu Ekutaurirana Nefoni: Kushanduka-shanduka, Tekinoroji, uye Mhedzisiro
Mumakumi emakore achangopfuura, masisitimu ekutaurirana nefoni akafambira mberi nekukurumidza uye zvakanyanya. Kubva paanalog kusvika padigital technology, kubva pa2G kusvika pa5G, masisitimu ekutaurirana nefoni akabatsira kubatanidza mabhiriyoni evanhu pasi rose. Kukurumidzisa uku uye nyore kwekutaurirana hakuna kungokanganisa hupenyu hwevanhu chete asiwo zvikamu zvakasiyana-siyana zvemaindasitiri nehurumende. Chinyorwa chino chichaongorora shanduko, matekinoroji akashandiswa, uye kukanganisa kwemasisitimu ekutaurirana nefoni.
Kushanduka kweSisitimu dzeKutaurirana dzeNharembozha
1. Chizvarwa Chekutanga (1G)
Kutanga kuma1970 kusvika kuma1980, kutaurirana nefoni kwakatanga kushandiswa uchishandisa masisitimu eanalog anozivikanwa se1G. Imwe yemasisitimu anozivikanwa zvikuru echizvarwa ichi yaive Advanced Mobile Phone System (AMPS), yaishandiswa muUnited States. Hunhu hukuru hwe1G hwaive kutumira data reanalog raingotsigira masevhisi ezwi chete. Kunyange zvazvo tekinoroji iyi yaive itsva munguva yayo, yaive nematambudziko akati wandei, akadai sekusakwanisa kwenetwork uye kuchengetedzwa kwakashata.
2. Chizvarwa Chechipiri (2G)
Yakatangwa kutanga kwema1990, 2G yaive shanduko huru kubva paanalog kuenda kudhijitari. Muyero weGlobal System for Mobile Communications (GSM) waive tekinoroji yakakosha yenguva iyoyo, zvichiita kuti spectrum ishande zvakanaka, pamwe nekutaurirana kwakachengeteka uye kwakavimbika. Munguva iyi, kuwedzera kune masevhisi ezwi, kutumirana mameseji (SMS) uye multimedia messaging (MMS) zvakatangwawo.
3. Chizvarwa Chechitatu (3G)
Yakaburitswa kekutanga mukutanga kwema2000, tekinoroji ye3G yakaunza kugona kweinternet nekukurumidza uye kwakavimbika kune vashandisi vefoni. Iyi tekinoroji yakagonesa kutumira data kune masevhisi emultimedia akadai sevideo conferencing, pamwe nefoni. UMTS (Universal Mobile Telecommunications System) neCDMA2000 ndiwo maviri ma standards anonyanya kushandiswa mu 3G technology.
4. Chizvarwa Chechina (4G)
Mumakore ekuma2010, tekinoroji ye4G yakatanga kutonga, ichipa kumhanya kwakanyanya kwenetwork uye kugona kupfuura 3G. Tekinoroji yeLong Term Evolution (LTE) ndiyo yaive tekinoroji yakakurumbira munguva ino, ichibvumira kumhanya kwekurodha kusvika kumazana emamegabits pasekondi. Izvi zvakagadzira nzira yemapurogiramu anoda bandwidth akadai seHD video streaming, online gaming, uye cloud-based applications.
5. Chizvarwa Chechishanu (5G)
Chizvarwa chitsva, 5G, chakatanga kushandiswa mukutengeserana mukupera kwa2010 nekutanga kwa2020. Nekumhanya kwacho kusvika kumagigabits akati wandei pasekondi uye kunonoka kwakaderera zvakanyanya, 5G inotarisirwa kuve chinhu chakakosha chinogonesa Internet of Things (IoT), mota dzinozvitonga, uye mamwe mashandisirwo akasiyana-siyana akavakirwa patekinoroji yepamusoro. Tekinoroji iyi inovimbisa kushandura nzira yatinoshandisa tekinoroji uye kuvhura mukana wekuvandudza mune ramangwana.
Matekinoroji Anoshandiswa muNharembozha dzeKutaurirana
Mafambiro eRadio uye Spectrum
Masisitimu ekutaurirana nefoni anoshandisa radio frequency spectrum kutumira data. Mumakore apfuura, mabhendi akasiyana-siyana ekufambisa mashoko akagoverwa pakutaurirana nefoni zvichibva pakugadzirwa kwetekinoroji inoshandiswa. Kutarisira maspectrum kwakakosha pakuona kuti kutaurirana hakukanganiswi uye kunoshanda zvakanaka.
Tekinoroji yeKupinda Kwakawanda
Matekinoroji akasiyana-siyana ekuwana ruzivo rwakawanda akadai seFDMA (Frequency Division Multiple Access), TDMA (Time Division Multiple Access), CDMA (Code Division Multiple Access), uye OFDMA (Orthogonal Frequency Division Multiple Access) akashandiswa kugadzirisa mashandisirwo espectrum uye kuwedzera kugona kwenetwork.
Antena neBase Station
Nzvimbo yekufambisa mashoko chinhu chakakosha muhurongwa hwekutaurirana nefoni. Maantenna ari panharembozha anotumira uye anogamuchira masaini eredhiyo kubva kuvashandisi. Nehunyanzvi hwemazuva ano hwakadai seMIMO (Multiple Input Multiple Output) uye beamforming, kugona kwenetwork uye kushanda zvakanaka kunogona kuwedzerwa zvakanyanya.
Network Yepakati
Pamusoro pe network yeredhiyo (RAN), network huru inoitawo basa rakakosha muhurongwa hwekutaurirana nefoni. Network huru inotarisira kufambiswa kwemafoni nedata, kusimbiswa kwemushandisi, uye manejimendi ekufamba. Matekinoroji akadai seEPC (Evolved Packet Core) mu4G uye 5G Core mu5G anogonesa kubatanidzwa kwakanaka pakati pemasevhisi akasiyana-siyana nemapurogiramu.
Mhedzisiro yeSisitimu dzeKutaurirana dzeNharembozha
upfumi
Kuvandudzwa kwenzira dzekutaurirana nefoni kwakakurudzira kukura kwehupfumi muzvikamu zvakasiyana-siyana. Indasitiri yekutaurirana nefoni pachayo ndiyo nhare yehupfumi hwepasi rose, ichigadzira mamiriyoni emabasa uye ichiwana mari yakawanda. Uyezve, mabasa ekubhadhara nefoni nedhijitari anotsigirwa nenzira dzekutaurirana nefoni zvakaita kuti pave nekuwana mabasa emari akawanda, kunyanya munyika dziri kusimukira.
Zvemagariro evanhu
Kubva pamaonero evanhu, masisitimu ekutaurirana nefoni akachinja nzira yatinotaurirana nayo. Mapurogiramu ekutumira mameseji ipapo ipapo, midhiya yemagariro evanhu, uye kufona nemavhidhiyo zvakapfupisa daro riri pakati pevanhu, zvichigonesa kutaurirana panguva chaiyo pasi rose. Uyezve, mukana wekuwana ruzivo nedzidzo wakawedzerawo zvikuru nekuda kwetekinoroji idzi, zvichideredza musiyano wedhijitari.
Guta Rakangwara neIoT
Nekuuya kwe5G, mukana wekushandiswa kwemaguta akangwara neIoT uri kuwedzera kuoneka. Masisitimu ekutaurirana nefoni anogonesa kutarisirwa kwezvivakwa zveguta zviri nani, kubva pakutarisira traffic uye kuchengetedzeka kusvika kune mamwe mabasa everuzhinji. IoT, inofambiswa ne5G connectivity, inopa kugona kubatanidza zvishandiso zvakasiyana-siyana, zvichigadzira nharaunda yakabatana uye inoshanda.
Kesehatan
Masevhisi ekurapa achishandisa nharembozha uye ehutano akasimba, kunyanya panguva yedenda reCOVID-19. Masisitimu ekutaurirana nenharembozha anogonesa kubvunzana nezvekurapa uri kure, kutarisa hutano panguva chaiyo, uye kutarisira data revarwere zviri nani.
Matambudziko uye Remangwana
Kuchengetedzeka uye Kuchengetedzwa Kwemashoko Akavanzika: Nekuwedzera kwehuwandu hwedata rinotumirwa kuburikidza nemasisitimu ekutaurirana nefoni, nyaya dzekuchengetedza uye kuchengetedzwa kwemashoko akavanzika dziri kuramba dzichiwedzera kuoma. Kurwiswa kwemakombiyuta nekutyorwa kwemashoko zvinogona kuva nemigumisiro yakakura, zvichiita kuti pave nekuvandudzwa kwemitemo yekuchengetedza yakaoma uye itsva.
Kuenzana Kwedhijitari: Kunyange hazvo tekinoroji yakabatanidza vanhu vazhinji, kusawirirana kwedhijitari kuchiripo mune dzimwe nzvimbo nenharaunda. Kuedza kupa mukana wakaenzana uye wakarurama kunofanirwa kuramba kuchisimbiswa, kuburikidza nemitemo yehurumende uye zvirongwa zvepachivande.
Simba Nezvakatipoteredza: Kushandiswa kwesimba nezvivakwa zvekutaurirana, kunyanya nzvimbo dzekuchengetedza ruzivo nedata centres, kune simba guru kune zvakatipoteredza. Kugadzira matekinoroji anoshanda zvakanaka uye asingakuvadzi zvakatipoteredza kuchava chinhu chikuru chichatariswa mune ramangwana.
Kubatanidzwa kweTekinoroji Itsva: Nekuvandudzwa kwetekinoroji dzakadai sehungwaru hwekugadzira (AI), blockchain, uye quantum computing, masisitimu ekutaurirana nefoni anotarisirwa kubatanidza izvi zvitsva kuti zvivandudze mashandiro enetwork, kuchengetedzeka, uye kushanda zvakanaka.
Mukupedzisa, kushanduka nekuvandudzwa kwemasisitimu ekutaurirana nefoni kwakaumba nyika yanhasi nenzira dzakawanda. Kubva pakutaurirana kwekutanga kusvika kumashandisirwo epamusoro akadai semotokari dzinozvitonga nemaguta akangwara, mukana wehunyanzvi uhwu wakakura. Zvisinei, matambudziko aripo anofanirwa kugadziriswa kuburikidza nekushandira pamwe pakati pezvikamu zvakasiyana kuti ive nechokwadi chekuti mabhenefiti ehunyanzvi uhwu anosvika padanho rega rega munharaunda.
