3G thiab 4G yog cov ntsiab lus siv los piav txog tiam thib peb thiab thib plaub ntawm kev pabcuam wireless cellular. 4G yog lub tshuab tshiab thiab feem ntau xa cov nrawm dua li 3G. Peb piv 3G thiab 4G thev naus laus zis los pab koj nkag siab qhov sib txawv ntawm qhov nrawm, muaj, thiab hom kev ua ub no hauv internet ua tau nrog txhua tus.
Kev Tshawb Nrhiav Txhua Yam
- tuaj yeem ncav cuag qhov nrawm ntawm 3.1 megabits ib ob lossis ntau dua.
- Kev nrawm cuam tshuam los ntawm lub zog ntawm lub teeb liab, qhov chaw, thiab kev sib txuas hauv network.
- 3G tseem siv nyob rau hauv cov chaw nyob deb nroog.
- Yuav nkag tau hauv internet.
- Ushered hauv multimedia nkag thiab thoob ntiaj teb roaming.
- tuaj yeem ncav cuag qhov nrawm txog 50 megabits ib ob.
- Kev nrawm hloov pauv nyob ntawm qhov deb ntawm lub network ntauwd.
- Cov neeg nqa khoom feem ntau muab kev pabcuam 4G hauv ntau thaj chaw hauv tebchaws.

3G feem ntau yog siv nrog cov xov tooj ntawm tes los ntawm kev sib txuas hauv internet. Feem ntau cov ntawv thov rau kev ua haujlwm hauv internet niaj hnub xws li GPS, huab cua, email, thiab kev sib tham ua haujlwm zoo ntawm kev sib txuas 3G.
4G tuaj yeem ua txhua yam 3G ua tau, tsuas yog sai dua. 4G kuj tseem tuaj yeem ua haujlwm siab-txhais mobile TV, videoconferencing, thiab lwm yam ntaub ntawv siv ntau heev. Yog tias koj saib YouTube yeeb yaj kiab, kwj Spotify, thiab tso siab rau ntau qhov sib txuas ntawm cov ntawv thov hauv internet txhua hnub, 4G yog qhov yuav tsum tau ua.
Muaj: 4G Yuav luag Txhua qhov
- Muaj nyob rau hauv cov chaw nyob deb nroog.
- Ua haujlwm rov qab rau qee qhov chaw muab kev pabcuam wireless.
- Muaj ntau ntxiv.
-
Tsis muaj nyob rau qee qhov chaw nyob deb nroog.
Thaum tus qauv 3G tseem siv nyob rau hauv cov chaw nyob deb nroog thiab ua qhov poob qis rau qee qhov chaw muab kev pabcuam wireless, nws feem ntau tau hloov los ntawm 4G.
4G thev naus laus zis muaj ntau thoob plaws ntiaj teb, tab sis 5G wireless thev naus laus zis tam sim no nyob rau hauv qhov xwm txheej, npaj kom co khoom thiab ua rau kev sib txuas lus hauv xov tooj sai dua thiab txhim khu kev qha raws li ntau cov khoom siv online.
Cov ntsiab lus 4G thiab 4G LTE feem ntau siv sib hloov, tab sis 4G LTE, uas sawv cev rau kev hloov pauv mus sij hawm thib plaub, muab kev ua haujlwm zoo dua thiab nrawm dua.
Kev Txiav Txim Kawg
Ob leeg 3G thiab 4G thev naus laus zis txuas cov neeg siv xov tooj ntawm tes mus rau hauv is taws nem thiab yog kev txhim kho loj dua cov qauv kev sib txuas ua ntej dhau los. Vim tias nws yog cov cuab yeej tshiab, 4G muaj qhov nrawm dua li 3G thiab tso cai rau ntau cov ntaub ntawv siv hauv online. Txawm li cas los xij, 3G yog qhov muaj txiaj ntsig zoo rau qee qhov chaw muab kev pabcuam wireless thiab muaj nyob hauv cov chaw nyob deb nroog.
