Technical Specifications 3G
3G ndiyo chizvarwa chechitatu cheterevhizheni. Iyo inouya nekunatsiridza pamusoro pekare-tambo dzisina utambo, kufanana ne-high-speed transmission, yakakura multimedia access, uye nyika inofamba-famba.
3G inowanzoshandiswa pamwe neserurafoni uye handsets sechimwe nzira yekubatanidza foni kuIndaneti kana mamwe maIndaneti kuitira kuti utaure mazwi nemavhidhiyo, kudhura uye kuisa data, uye kufambisa Webhu.
Nhoroondo
3G inotevera muenzaniso weG wekuti ITU yakatanga kutanga kwema1990. Nzira yacho inonyanya kushandiswa kusina foni inonzi IMT-2000 (International Mobile Communications 2000). 3G, naizvozvo, inouya pashure pe 2G uye 2.5G , yechipiri-generation generation technologies.
2G technologies inosanganisira, pakati pevamwe, Global System for Mobile ( GSM ). 2.5G yakaunza mitemo iri pakati pe 2G ne3G, kusanganisira General Packet Radio Service ( GPRS ), Enhanced Data zvinyorwa zve GSM Evolution ( EDGE ), Universal Mobile Telecommunications System (UMTS), nevamwe.
3G Zviri nani?
3G ine zvinyorwa zvinotevera pane 2,5G uye nhepfenyuro yapfuura:
- Nenguva dzakawanda dzakakwirira dhigirii.
- Kuwedzerwa mavhidhiyo nemavhidhiyo kubuda.
- Videoconferencing support.
- Webhu neKV pakutsvaga pakureba.
- IPTV (TV kuburikidza neIndaneti) tsigiro.
Technical Specifications
Kuwedzerwa kwemasero 3G iri pakati pe 128 ne144 kbps (kilobiti pamusi wechipiri) yezvigadziri zvinofamba nekukurumidza, uye 384 kbps yezvishoma zvishoma (kufanana nevatambi vanofamba). Kune maLAN asina kusina wireless, kasi inopfuura 2 Mbps (2,000 kbps).
3G igadziriro yemichina uye mitemo inosanganisira W-CDMA, WLAN, uye redhiyodhiyo, pakati pevamwe.
Zvido zvekushandisa
Chigadzirwa chinonzi 3G chinobvumirana, sefoni kana tablet, ndicho, chechokwadi, chekutanga chinodiwa. Iyi ndiyo iyo zita rokuti "3G foni" inobva--foni ine mabasa 3G. Izwi iri harina chokuita nehuwandu hwekamera kana chiyeuchidzo chaicho. Muenzaniso ndiyo iPhone 3G.
3G foni zvinowanzove nemakamera maviri sezvo teknolojia inobvumira musikana kuva nemavhidhiyo ekufonera, umo kamera inotarisa-user inodawo.
Kusiyana neWi-Fi , iyo yaunogona kuwana yekusununguka muma hotspots , unofanirwa kunyoresa kumushandi webasa kuti uwane hutano hwe 3G. Iko rudzi rwebasa rinowanzodanwa chirongwa che data kana network plan.
Chigadzirwa chako chakabatanidzwa nehutano hwe 3G kuburikidza neSIM khadi yayo (kana iri foni) kana kadiro yayo yeGadhi 3G (iyo inogona kuva yakasiyana-siyana, yakadai se USB , PCMCIA, nezvimwewo), zvose zviripo zvinowanzopiwa kana kuti inotengeswa nemupiki webasa.
Iyi ndiyo nzira iyo iyo inobatana nayo paIndaneti kana iri mukati mehutano hwe 3G. Kutaura zvazviri, chigadzirwa chacho chiri shure chinowirirana nehutano hwekare, ndicho chikonzero foni inobvumirana nayo 3G inogona kuwana 2G service kana iripo kana 3G yebasa isiri.
Chii Chinokwana 3G?
3G haisi shoma, asi zvakakosha kune vashandisi vanoda kubvumirana pavanenge vachifamba. Vamwe vanopa zvipo vanozvipa mukati mechikwata chinodhura, asi vazhinji vavo vanogadzirira apo munhu anopa mari yehuwandu hwemashoko akatamiswa, nokuti teknolojia ndiyo ipakiti -yakagadzirirwa. Semuenzaniso, kune zvirongwa zvebasa apo pane chidimbu chepamusoro che gigabyte yekutanga ye data yakashandurwa, uye per-megabyte kana yega-gigabyte mari inotevera.
3G nezwi
Uterevhizheni dzesayenzi inzira yevashambadziri vese vanoita mahwindo kana kudhura pasi pose uye kuchengetedza mari yakawanda nekuda kwemazuva ano telefony zvikumbiro nemabasa. 3G mitambo ine ruzivo rwekuwanika pakufamba, kusiyana ne Wi-Fi, iyo inongogumira kumamita mashomanana ekupoteredza router emitting.
Munhu anoshandisa faira yepa 3G uye deta akanyatsosungirirwa pakugadzira mafonero asina kufanira. Vanozofanira kuisa chimwe chezvinhu zvakawanda zviripo zviripo zveVoIP , seViber, WhatsApp, kana Telegram.
