Zolemba zamakono za 3G
3G ndi m'badwo wachitatu wa matekinoloje opanda waya. Zimabwera ndi zowonjezera pa matekinoloje osayendetsa apamwamba, monga kuthamanga kwambiri, kuthamanga kwa multimedia, ndi kuyendayenda padziko lonse.
3G amagwiritsidwa ntchito kwambiri ndi mafoni a m'manja ndi mafoni osakaniza monga njira yolumikiza foni ku intaneti kapena ma intaneti ena kuti apange ma volo ndi mavidiyo, kukopera ndi kukweza deta, ndi kufufuza pa intaneti.
Mbiri
3G ikutsatira ndondomeko ya G yomwe ITU inayambira kumayambiriro kwa zaka za m'ma 1990. Chitsanzocho ndi njira yopanda waya yotchedwa IMT-2000 (International Mobile Communications 2000). 3G, motero, imabwera pambuyo pa 2G ndi 2.5G , zamakono zamakono.
Mafilimu a 2G akuphatikizanso, pakati pa ena, Global System for Mobile ( GSM ). 2.5G amapanga miyezo yomwe imakhala pakati pa 2G ndi 3G, kuphatikizapo General Packet Radio Service ( GPRS ), Mapulogalamu Owonjezeka a GSM Evolution ( EDGE ), Universal Mobile Telecommunications System (UMTS), ndi ena.
Kodi 3G Ndi Bwino Motani?
3G ili ndi zowonjezera zowonjezera ma intaneti a 2.5G ndi apitalo:
- Nthaŵi zingapo zapamwamba zamtundu wa deta.
- Zapititsa patsogolo mavidiyo ndi mavidiyo.
- Thandizo la Videoconferencing.
- Mawindo a pawebusaiti ndi WAP pakapita msinkhu.
- IPTV (TV kudzera pa intaneti) chithandizo.
Zolemba zamakono
Kuwongolera kwa mawebusaiti a 3G ndi pakati pa 128 ndi 144 kbps (kilobits pa mphindi) kwa zipangizo zomwe zikuyenda mofulumira, ndi 384 kbps zapang'onopang'ono (monga oyenda oyendayenda). Kwa ma LAN osayendetsedwa opanda waya , liwiro limapitirira kuposa 2 Mbps (2,000 kbps).
3G ndi ndondomeko ya matekinoloje ndi miyezo yomwe ikuphatikizapo W-CDMA, WLAN, ndi wailesi yam'manja, pakati pa ena.
Zofunika Zogwiritsiridwa Ntchito
Chida chogwiritsidwa ntchito ndi 3G, monga foni kapena piritsi, ndilo, chofunikira choyamba. Apa ndi pamene "3G foni" imachokera ku-foni yomwe ili ndi machitidwe 3G. Mawuwo alibe chochita ndi chiwerengero cha makamera kapena chikumbutso chomwe chiri nacho. Chitsanzo ndi iPhone 3G.
Mafoni a 3G amakhala ndi makamera awiri popeza teknoloji imalola wophunzira kukhala ndi mavidiyo, momwe makamera akuyang'anitsitsa akufunikanso.
Mosiyana ndi Wi-Fi , zomwe mungapeze kwaulere m'malo opangira maofesi, muyenera kulembetsa kwa wothandizira mauthenga kuti muthandizidwe. Ntchito yotereyi nthawi zambiri imatchedwa dongosolo la deta kapena ndondomeko.
Chida chanu chikugwirizanitsidwa ndi makina a 3G kupyolera mu SIM khadi (pafoni ya foni) kapena khadi lake la deta la 3G (lomwe lingakhale la mitundu yosiyana, monga USB , PCMCIA, etc.), zonsezi zimaperekedwa kapena wogulitsidwa ndi wothandizira.
Izi ndi momwe zipangizo zimagwirizanirana ndi intaneti pamene zili mu intaneti ya 3G. Ndipotu, chipangizocho chimagwirizananso ndi zipangizo zakale, ndipo chifukwa chake foni yovomerezeka ya 3G ikhoza kutenga 2G utumiki ngati ilipo pamene utumiki wa 3G suli.
Kodi Mtengo wa 3G Ndi Chiyani?
3G sizitsika mtengo, koma ndizofunikira kwa ogwiritsa ntchito omwe akusowa kulumikizana. Ena opereka amapereka phukusi la mtengo wapatali, koma ambiri a iwo akukonzekera komwe wogwiritsa ntchito ndalama amapereka ndalama, chifukwa teknoloji ndi paketi -yiyi. Mwachitsanzo, pali mapulani othandizira omwe ali ndi mlingo wokwanira wa gigabyte yoyamba ya deta, ndipo mtengo wa megabyte kapena gigabyte pambuyo pake.
3G ndi Liwu
Zipangizo zamakina zam'manja ndi njira yomwe anthu ogwiritsa ntchito mafoni amayendera maofesi kapena otsika mtengo padziko lonse ndikusunga ndalama zambiri chifukwa cha mapulogalamu ndi mautumiki atsopano. Mabungwe a 3G ali ndi ubwino wokhalapo pamsuntha, mosiyana ndi Wi-Fi, yomwe ili ndi mamita ochepa pamtunda wotumiza .
Wogwiritsa ntchito ndondomeko ya foni ya 3G ndi deta ali wokonzeka bwino popanga mafoni a m'manja aulere. Adzangowonjezera imodzi mwazinthu zomwe zilipo za VoIP , monga Viber, Whatsapp, kapena Telegram.
