Kodi osiyana ndi 4G 3G ndi zimene kusankha?

moyo wathu mofulumira, ndipo mauthenga ndi tikaumbike m'mlengalenga tsiku lililonse. Masiku ano, anthu ochepa ndi kukhuta, moti ntchito foni kungokhala mu kukhudza, ndipo tsopano aliyense akufuna kukhala mbali mokwanira mu danga zambiri. zipinda Chat, Intaneti, kanema - zithumwa onsewa amafuna kuti ndi kugwirizana okhazikika Intaneti. Otetezeka mwayi mpaka kalekale maukonde ndi zosavuta, ngakhale wotchipa kwambiri zitsanzo foni ndi mwayi kupyolera m'mphepete ndi GPRS. Ndipo ngati tikukamba za kugwirizana mkulu-liwiro, ndiye zonse ndi kovuta, ngati pali mwayi wosankha. Ndipo nthawi zonse chopweteka.

magwero a pulayimale

Njira zosavuta ndi ambiri kuonetsetsa nokha Internet mafoni ndi mafoni telephony muyezo GPRS, m'mphepete ndi 3G. Last sitinganene kuti muyezo. Ichi ndi mawu losonkhanitsidwa amene abisa ya malamulo. Ngati chipangizo ali kuthandiza 3G, 4G, ndi kupezera mwiniwake Intaneti pa liwiro apamwamba. Ngati mbendera adzakhala mavuto, zida ndi zosavuta kusinthana kwa ina muyezo m'mphepete kapena GPRS. Malinga ndi ntchito mwini m'manja, 3G maukonde ndi ponseponse. Komabe likukhalira si choncho peachy. Pali mavuto ambiri kugwirizana ndi zinthu zosiyanasiyana, lomwe ngakhale mpumulo, zochitika zachilengedwe , ndi padzuwa. Musanayambe kuganiza za kusiyana 3G ku 4G, muyenera kumvetsa zosiyanasiyana zina zabwino.

ntchito zake zosiyanasiyana

3G-Intaneti panopa ndi zosinthika ambiri, choncho 99% mayunitsi ndi ntchito ndi mfundo imeneyi. Poyamba, Internet mafoni ndi chophweka njira ya kutaya m'zikwama, ndipo tsopano ntchito ndi okonzeka kupereka ogula zosiyanasiyana mapulani tariff.

Ngati ife kulankhula za kusiyana 3G ku 4G, ndi chinthu chofunika kwambiri, oddly mokwanira, pali liwiro. Kwakukulu chiwerengero cha anthu olumikizidwa kwa njira, ang'onoang'ono adzakhala ake bandiwifi. Ngati ife kuwonjezera m'madera lamavutoli vuto Kuphunzira, kuchokera liwiro ongolankhula kuchita masamu yekha lachitatu. Komabe, izi ndi zoona okha m'madera kachulukidwe mkulu wa olembetsa - chifukwa malo amene kuli anthu ndi midzi, komanso pamene galimoto. Mu zikhalidwe zina, mlingo zina kudumpha kulemba mfundo.

asadziphe

Pamaso tikukamba za kusiyana 3G ku 4G, tiyenera kuganizira bwana wa ntchito ntchito ndi muyezo CDMA. Limatchula njira imeneyi kumafuna njira chosiyana vuto la njira katundu ndi chiwerengero cha owerenga. Quality ndi kupezeka kwa chizindikiro adalira, monga nthawi zina zosiyanasiyana zinthu. Komabe, Chiwerengerochi ntchito CDMA luso n'zofunika kwambiri kuposa GSM ntchito. Pansi makhalidwe abwino liwiro pazipita zili ndi megabits 3.2 pa mphindi.

Dziwani kuti 3G routers, 4G, CDMA si osiyanasiyana ntchito GSM. Komabe, ngati n'koyenera, ndipo apa mungapeze "chanu" chipangizo kuti adzakhala yabwino kwa inu ntchito.

zopezera LTE

Musanayambe amatiuza za chimene ndi chosiyana ndi 4G 3G, izo ziyenera kunenedwa za Intaneti LTE, amene anayambitsa posachedwapa ndi ntchito zingapo ku Russia. Mu dziko, mbendera wakhala ukugwira ntchito kwa zaka. Vuto ndi kugwiritsa ntchito Intaneti izi mu Russia kwagona mabotolo onse achilendo ntchito chosiyana pafupipafupi osiyanasiyana. Koma ntchito Russian kupereka makasitomala awo kusankha zipangizo zoyenera kuti wosuta Intaneti amenewa, komanso dongosolo mulingo woyenera tariff ndipo nkhani yabwino. Mapulogalamuwanso angathe kusankha osiyanasiyana zipangizo za zovuta, kuphatikizapo USB-modems ndi Wi-Fi-routers ndi anamanga-mu batire rechargeable kuti akhoza adzaikidwa mu thumba ndi osadandaula kuti ulendo adzakhala mavuto ndi Intaneti. Pali muyezo routers kuti akhoza olumikizidwa kwa magetsi a mumzindawo ndi ntchito kunyumba.

zopezera 4G Kuphunzira

Choncho kusiyana 3G ku 4G? Dziwani kuti pa Intaneti awiri ndi madera bwino chimatanthauza Kuphunzira. Ngati chachiwiri, vuto kukuikira otsika maukonde, nthawi zambiri, ntchito 4G yekha m'mizinda ikuluikulu. Mu Moscow ndi malo Moscow kuphimba unagawanika. Woyamba wa ntchito ya kukhala mtundu watsopano wa ❖ kuyanika, msika anapita "Megaphone". Ndipo tsopano iye ali Kuphunzira malo pazipita kwa Russian dera lonse. Nkofunika kuzindikira kuti 3G / 4G kusinthitsa kumachitika pang'onopang'ono, choncho m'dera Kuphunzira chidzakula ndi nthawi. malo a wina woyendetsa mafoni nthawi lili ndi mfundo zogwirizana za m'dera Kuphunzira.

The kampani "MTS" mu Moscow ndi dera Moscow wakhala wotetezedwa yachiwiri malo mapeto, zomwe zidatheka chifukwa chitukuko yogwira maukonde. M'dera osachepera kwa woyendetsa "Beeline", pamene anali nawo "mtundu" pambuyo pa zonse.

mtengo

Choncho, mosiyana ndi 3G ku 4G ndi njira kwa kukhazikitsa, koma mtengo - ichi ndi chinthu china kwambiri pa nkhani ya Intaneti onse. 4G liwiro sasunthika ndi woyendetsa za m'manja, ndipo zimadalira m'mene yodzaza maukonde pa mphindi. wosuta angathe kukhala dongosolo tariff iliyonse, pamene kufunika kwake kudzadalira pa bandiwifi zilipo.

zida

Opanda zingwe 3G kapena 4G-Internet akutumikira monga njira ina basi anatumizanso lamya intaneti. Zimenezi ndi zoona makamaka kumene basi anatumizanso lamya utumiki wosamalira palibe. Mwachitsanzo, ngati muli kanyumba kapena nyumba ndi nyumba yatsopano, mumagwiritsa ntchito yabwino liwilo Intaneti simungathe wavulala. Imeneyi, njira yabwino ndiyo ntchito 3G kapena 4G-rauta. Iwo akhala akugwira osati kwa gulu la kufalitsa opanda zingwe Intaneti Wi-Fi, komanso kupeza mwayi khola Intaneti, kumene phwando mbendera ndi chosadziwika. Kuchita izi, ntchito mlongoti kunja kapena mlongoti mkuzamawu.

3G ndi chiyani?

3G - luso opanda zingwe zambiri ubwino poyerekeza ndi mibadwo kale. Zina kupanga kusiyana, makamaka, mkulu-liwiro HIV, maluso patsogolo pa matumizidwe ophatikizika amawu, nyimbo ndi zithunzi, komanso woyendayenda lonse. Njira imeneyi ntchito kulumikiza mafoni ku Internet kapena ena Intaneti IP ofotokoza ogula ndi mwayi mawu kapena kanema kulankhulana, komanso kugwiritsa ntchito Intaneti ndi kutsitsa owona.

4G ndi chiyani?

Ngati ife kulankhula za 3G Mosiyana 4G, ndiye Ndipotu, muyezo waukulu ndi kuti yotsirizira amagwiritsa latsopano muyezo pafupipafupi osiyanasiyana, kotero kuti palibe m'mbuyo ngakhale luso. 4G umalimbana kupereka chitetezo mabuku onse IP ofotokoza (IP-telephony, misonkhano Masewero, mwayi burodibandi Internet, ndi kusonkhana matumizidwe ophatikizika amawu, nyimbo ndi zithunzi zomwe zili).

4G ndi 3G

Kumvetsetsa kusiyana matekinoloje awiri n'kofunika kuganizira mfundo zina.

Mfundo yoyamba kwambiri poyerekeza ndi liwiro. Pali sangathe adzatchedwa muyezo, amene ali bwino. Mbali yoyamba, monga tanenera kale, mlingo mwachindunji amadalira Kuphunzira maukonde. 4G ntchito nthawi 10 msanga poyerekeza ndi 3G. Izi zidalira pa zida ntchito amveke wa chizindikiro ndi deta.

Kubwera kwa 3G chinathandiza owerenga yanji mawu ndi kusamutsa Deta liwilo. Pankhaniyi chinawonjezeka ndi 4G HIV liwiro kwambiri, powonjezera, ogula ankatha kugwiritsa ntchito matumizidwe ophatikizika amawu, nyimbo ndi zithunzi zomwe zili mwachindunji pa Intaneti masewera Intaneti. Itanani ntchito ndi deta m'nkhani ino ndiponso mulandu wina, ntchito pa nthawi yomweyo.

kutengerapo luso

3G amagwiritsa njira deta kusinthitsa wa mfundo network ndi phukusi. kokha paketi kusinthitsa ntchito 4G. Ngati inu yerekezerani matulukidwe Intaneti onse, simungathe kumva kusiyana kulikonse. The 4G kuyitana zonse ntchito IP-telephony, amene palibe pa 3G.

Onse maukonde ukuthamana mtengo pafupi zofanana, ndipo msinkhu wa 5-20 Mbit / s.

Pomaliza

Kumene, 4G akuimira zipangizo zatsopano kwambiri, koma kukhazikitsa zonse sanabadwe zikadzachitika, kotero owerenga sangathe kudzasangalala ndi mapindu. Popeza kuthandiza 3G, 4G sanayambebe anayamba chokwanira kuchititsa pa mlingo kwina, ntchito zimene tiyenera kupezeka kwa owerenga, ndi pa siteji oyambirira kukhazikitsa. atsopano m'badwo maukonde ndi kulemera mbali zambiri osati kwathunthu ankafufuza, ndi zida zamakono tsiku lililonse likadutsa amakhala zovuta kwambiri, ubwino onse a sayansi adzakhala akuoneka okha patapita kanthawi, ndiyeno ife chingayerekezedwe 3G ndi 4G-Internet kwathunthu.
