Masisitimu Ekukurukurirana Nenharembozha: Kuchinja Kubatana
Kutanga kwezana remakore rechi21 kwakaona kuchinja kukuru mukutaurirana kwedu, zvichikonzerwa nekushanduka-shanduka kwemafoni. Kubva pamazuva ekutanga emafoni makuru ane hunyanzvi hushoma uye mashandiro mashoma kusvika kumafoni emazuva ano emazuva ano ari makombiyuta anobatwa nemaoko, masisitimu ekutaurirana emafoni akachinja nzira yatinobatanidza nayo uye nyika. Muchinyorwa chino, tichaongorora kukura, magadzirirwo, matekinoroji, uye mafambiro emangwana mumafoni ekutaurirana akaita kuti kubatana kwakadaro kuve nyore.
Kushanduka kweSisitimu dzeKutaurirana dzeNharembozha
Rwendo rwemasisitimu ekutaurirana nefoni rwakatanga pakati pezana remakore rechi20 nechizvarwa chekutanga (1G). Aya masisitimu eanalog, akatangwa kuma1980, akapa kutaurirana kwezwi kwekutanga asi akatambudzwa nezvikanganiso zvakawanda zvinosanganisira kunaka kwezwi, kugona kushoma, uye kushaya kuchengetedzeka. Pasinei nezvikanganiso izvi, 1G yakaisa hwaro hwekufambira mberi mune ramangwana.
Kubuda kwechizvarwa chechipiri (2G) muma1990 kwakaratidza kuenderera mberi kukuru, kuchinja kubva pakutaurirana kweanalog kuenda kudhijitari. Matekinoroji akadai seGSM (Global System for Mobile Communications) neCDMA (Code Division Multiple Access) maprotocol ekutaurirana akajairwa, kunaka kwezwi kwakavandudzwa, uye kwakaunza mameseji (SMS). Uyezve, masisitimu e2G akabatanidza matekiniki ekutanga ekuvhara, zvichiwedzera kuchengetedzeka kupfuura chizvarwa chakapfuura.
Zvizvarwa zvakatevera, 3G ne4G, zvakaunza mukana weinternet kune nharembozha, ne3G ichiunza masevhisi edata renharembozha uye ichigonesa maapplication emultimedia, uye 4G ichipa internet inokurumidza, ichitsigira maapplication akaita seHD video streaming uye online gaming. Pamusoro pezvo, kuiswa kwetekinoroji yeLTE (Long Term Evolution) mumanetwork e4G kwakavandudza zvakanyanya latency uye data transfer rates.
Magadzirirwo eSisitimu dzeKutaurirana neNharembozha
Masisitimu ekutaurirana nefoni anoshanda kuburikidza nehurongwa hwakaoma hune zvikamu zvakakosha zvakati wandei. Pakati pehurongwa uhwu pane network yenharembozha, iyo inogona kukamurwa kuita zvikamu zviviri: Radio Access Network (RAN) uye Core Network.
1. Network yekupinda muredhiyo (RAN):
RAN inobatsira kubatana pakati pemafoni nenetwork huru. Inosanganisira nzvimbo dzekushandisa, maantenna, uye maredhiyo. Mumasisitimu emazuva ano, RAN inoshandisa matekinoroji epamusoro akadai seMIMO (Multiple Input Multiple Output), zvichiita kuti ishandiswe zvakanaka uye ivandudze kugona kwedata.
2. Network Yepakati:
Network huru inotarisira data uye traffic yezwi, ruzivo rwevanonyoresa, uye kubatana kune network dzekunze. Zvinhu zvakakosha zve network huru zvinosanganisira Mobile Switching Center (MSC), Home Location Register (HLR), Serving GPRS Support Node (SGSN), uye Gateway GPRS Support Node (GGSN). Zvikamu izvi zvinovimbisa kutaurirana kwakanaka pakati pemasero, kugadzirisa kufamba kwemushandisi, uye kupa ruzivo rwechokwadi uye rwekubhadhara.
Tekinoroji Dzakakosha muSisitimu Dzemazuva Ano Dzekutaurirana Nenharembozha
Matekinoroji akawanda epamusoro anotsigira masisitimu emazuva ano ekutaurirana nefoni, zvichitungamira mashandiro awo, kushanda zvakanaka, uye kugona:
1. Matekiniki Ekuwana Akawanda:
Matekiniki akawanda ekuwana ruzivo akadai seFDMA (Frequency Division Multiple Access), TDMA (Time Division Multiple Access), CDMA (Code Division Multiple Access), uye OFDMA (Orthogonal Frequency Division Multiple Access) anobvumira vashandisi vakawanda kushandisa nzira imwe chete yekutaurirana pasina kukanganiswa, nokudaro zvichiwedzera kushandiswa kwespectrum iripo.
2. Kugadzira mwenje uye MIMO Yakakura:
Tekinoroji yeBeamforming inotungamira kutapurirana kwemasaini kune vashandisi vakasiyana pane kuparadzira mafambiro ese, ichivandudza simba remasaini uye ichideredza kupindirana. MIMO yakakura, ine maantenna akawanda pazviteshi zvepasi, inovandudza kugona uye kushanda zvakanaka kwespectrum nekushandira vashandisi vakawanda panguva imwe chete.
3. Manetwork Akasiyana-siyana (HetNets):
HetNets inobatanidza macro cells nemasero madiki (akadai se micro, pico, uye femtocells) uye Wi-Fi hotspots, zvichiita kuti pave nekufukidzwa kwakafanana uye kugona kushanda munzvimbo dzakasiyana-siyana. Inoita kuti mutoro ugare wakaenzana zvakanaka uye inovandudza ruzivo rwevashandisi, kunyanya munzvimbo dzine vanhu vakawanda.
4. Kuunganidzwa kweVatakuri:
Kuunganidzwa kwevatakuri kunobatanidza mabhendi akawanda ema frequency kuti kuwedzere kuburitswa kwedata uye kuwanikwa kwebandwidth. Iyi tekinoroji yakakosha mukuderedza kushomeka kwema spectrum uye kusimudzira mashandiro enetwork.
5. Kucheka Network:
Kucheka network kunobvumira kugadzirwa kwema network akawanda ari pakombiyuta imwe chete, akagadzirirwa kusangana nezvinodiwa zvekushandisa. Izvi zvakakosha kune ma network e5G, zvichibatsira pakushandiswa kwakasiyana-siyana kubva pakuwedzera broadband yefoni kusvika pakukurukurirana kwakaderera (URLLC) uye kutaurirana kwemhando yemuchina (mMTC).
6. Kombiyuta yeEdge:
Edge computing inoswededza kugadzirisa data pedyo nemushandisi wekupedzisira, zvichideredza kunonoka uye zvinovandudza mashandiro eapplication panguva chaiyo. Izvi zvakakosha kumaapplication akadai se autonomous driving, augmented reality (AR), uye Internet of Things (IoT) services.
Mafambiro Emangwana: 5G Nekupfuura
Kutangwa kwe5G networks kunoratidza imwe danho rekuchinja mune zvekutaurirana zvefoni. 5G inovimbisa kumhanya kusingaenzaniswi, kugona, uye kunonoka kunonoka, zvichigonesa maapplication nemasevhisi akawanda matsva. Zvinhu zvikuru zve5G zvinosanganisira:
1. Broadband Yenharembozha Yakavandudzwa (eMBB):
5G eMBB inopa data rakawanda, vhidhiyo inotepfenyurwa zvakanaka, uye ruzivo rwechokwadi rwakadzama uye rwakawedzerwa. Inotsigira maapplication anoda bandwidth yakakura uye kubatana nekukurumidza.
2. Kutaurirana kweLatency Yakaderera Kwakasimba (URLLC):
URLLC yakagadzirirwa kushandiswa pabasa rakakosha sekushanda uri kure, otomatiki yemumaindasitiri, uye mota dzinozvishandira dzoga. Inoita kuti pave nenguva shoma uye kuvimbika kwakanyanya, zvakakosha pakushanda panguva chaiyo.
3. Kutaurirana Kwakawanda Kwemhando Yemuchina (mMTC):
mMTC inotsigira huwandu hwakawanda hwezvishandiso zveIoT, zvichigonesa maguta akangwara, IoT yemaindasitiri, uye kutarisa nharaunda. Inosimbisa kubatana nekukurumidza, ichivimbisa kutaurirana kwakanaka pakati pemamiriyoni ezvishandiso.
Matambudziko nemikana
Pasinei nekufambira mberi kunoshamisa, matambudziko akati wandei achiripo munyaya dzekutaurirana kwemafoni:
1. Kushomeka kweSpectrum:
Kuwanda kuri kuramba kuchida masevhisi emagetsi asingashandise waya kuri kuwedzera kushomeka kwema spectrum. Kutarisira ma spectrum zvakanaka, kuchinjisa nzvimbo, uye kushandiswa kwema frequency bands akakwira (semuenzaniso, ma millimeter waves) zvakakosha pakugadzirisa dambudziko iri.
2. Kuchengetedzeka uye Ruzivo Rwepachivande:
Nekuwanda kwemidziyo yakabatana, kuve nechokwadi chekuchengetedzwa kwakasimba uye kuchengetedza zvakavanzika zvemushandisi kwakakosha. Kuvandudzwa kwe encryption, nzira dzepamusoro dzekusimbisa, uye magadzirirwo enetwork akachengeteka zvakakosha kurwisa kutyisidzira kuri kuchinja kweinternet.
3. Kudyara Mari muZvivakwa:
Kushandisa network dzechizvarwa chinotevera se5G kunoda mari yakawanda muzvivakwa. Kushandira pamwe pakati pehurumende, maindasitiri, nemakambani ekutaurirana kwakakosha kuti pave nekubudirira uye kushandiswa kwakapararira kwetekinoroji itsva.
4. Kubatana Kwepasi Pose:
Kugadzirisa musiyano uripo pakati pedhijitari uye kuona kuti kubatana kwepasi rose kuchiri matambudziko makuru. Kuwedzera ruzivo kunzvimbo dziri kure uye dzisina rubatsiro rwakawanda kwakakosha mukusimudzira kukura nebudiriro yakabatana.
Mukupedzisa, masisitimu ekutaurirana nefoni akachinja zvachose kubatana, achitungamira kufambira mberi kwehupfumi uye achichinja hupenyu hwedu hwezuva nezuva. Kushanduka kubva pa1G kuenda ku5G kwakavhura mikana isingaenzaniswi, uye ramangwana rine vimbiso yakakura netekinoroji itsva nekuvandudzwa kuri kubuda. Sezvatinoenderera mberi, kugadzirisa matambudziko nekushandisa mikana zvichave zvakakosha pakuzadzisa kugona kwakazara kwemasisitimu ekutaurirana nefoni uye kugadzira nyika yakabatana kune wese munhu.
