Yini lihlukile 3G 4G kanye lokho ukukhetha?

Ukuphila kwethu usheshisa futhi ulwazi ohlangene umoya nsuku zonke. Namuhla, bambalwa abantu benelisekile, ukuze usebenzisa iselula nje uhlale uxhumene, futhi manje wonke umuntu ufuna ngokugcwele kufakwe isikhala ulwazi. zengevu, ukuxhumana nomphakathi, ividiyo - zonke lezi izintelezi zidinga ukuze abe uxhumano unomphela kwi-Inthanethi. Secure ukufinyelela unomphela kwinethiwekhi kulula, ngisho ezishibhile kakhulu zamafoni ukufinyelela ngokusebenzisa EDGE kanye GPRS. Futhi uma sikhuluma uxhumano ngesivinini esikhulu, bese zonke kunzima ngempela, njengoba kukhona lokuzikhethela. Futhi kuba njalo ezibuhlungu.

imithombo Primary

Indlela elula futhi ezivamile ukuqinisekisa ngokwakho Internet mobile kuyinto mobile sefoni standard GPRS, EDGE kanye 3G. Kugcine akakwazi ngokuthi ejwayelekile. Lena elithi collective efihla lwezimiso. Uma idivaysi has usekelo 3G, 4G, ikwazi ukunikeza umnikazi ukufinyelela kwayo ku-inthanethi ngesivinini esiphezulu. Uma isignali okunjalo kuyoba nezinkinga, imishini Kulula ukushintshela sangaphambili EDGE ejwayelekile noma GPRS. Ngokusho siqu opharetha mobile, inethiwekhi 3G ukuyo yonke indawo. Kodwa umkhuba kuvela akuyona peachy ngakho. Kukhona okuningi yezinkinga ezihambisana izici ezihlukahlukene, futhi phakathi lapho ngisho impumuzo, zemvelo , futhi elangeni. Ngaphambi kokuba ucabange umehluko phakathi 3G kusukela 4G, kungase kudingeke uqonde ezihlukahlukene umehluko wemisindo nemiqondo yamagama.

yizinhlobonhlobo

3G-inthanethi okwamanje okufana ezivamile, ngakho-99% wama Amayunithi asebenta nalelicembu ejwayelekile. Ngaphambili, i-Internet mobile kuyindlela elula of bethulula esikhwameni, futhi manje opharetha bakulungele ukunikeza amakhasimende ayo ezihlukahlukene tariff izinhlelo.

Uma sikhuluma umehluko phakathi 3G kusukela 4G, ke kuyinto ebalulekile, Isimanga siwukuthi, kukhona ijubane. Kukhula isibalo sabantu exhunywe kwi-siteshi, ezincane kuyoba yayo komkhawulokudonsa. Uma sinezela lokhu eziyinkimbinkimbi inkinga Ukusabalala izindawo, kusukela ijubane theory ingabalwa kuphela eyesithathu. Nokho, lokhu kuyiqiniso kuphela ezindaweni nge high density ababhalisile - ezindaweni ezinabantu abaningi nemizana, kanye lapho ushayela. Ngamanye izimo, izinga ngezinye izikhathi kuzuba ukurekhoda amagugu.

ezinye izinketho

Ngaphambi sikhuluma umehluko phakathi 3G kusukela 4G, kufanele sicabangele iziphakamiso opharetha isebenzisana CDMA ejwayelekile. Imininingwane lobu buchwepheshe kuhilela isixazululo ehluke ngophelele inkinga kwesiteshi umthwalo kanye nenani abasebenzisi. Quality nokutholakala isignali zincike, njengoba kwezinye izimo, ezahlukahlukene. Kodwa noma kunjalo, lezi izibalo usebenzisa CDMA ubuchwepheshe ingcono kakhulu GSM ukusetshenziswa. Ngaphansi kwezimo ezifanele ijubane esiphezulu isesikhathini 3.2 megabits ngomzuzwana.

Kuyaphawuleka ukuthi 3G imizila, 4G, CDMA akuyona labamihibahiba usebenzisa GSM. Nokho, uma uthanda, futhi lapha ungathola kudivayisi "yakho 'oluyoba esilungele wena ukuyisebenzisa.

inethiwekhi LTE

Ngaphambi usitshele lihlukile 3G 4G, kufanele ishiwo LTE, eyayibonakala umkhankaso muva by opharetha abambalwa eRussia. Ezweni, le ndinganiso abelokhu esebenza iminyaka. Inkinga nge kokusebenzisa lawo manethiwekhi eRussia itholakala lokuthi ukuthi wonke amayunithi angaphandle usebenza ehluke ngokuphelele imvamisa ububanzi. Kodwa opharetha Russian ukunikeza amakhasimende abo ukukhetha imishini esifanele umsebenzisi amanethiwekhi enjalo, kanye elilungile imali plan kanye Ukuhlanganisa best. Abasebenzisi angakhetha ezihlukahlukene kumadivayisi we eziyinkimbinkimbi, kuhlanganise i-USB modems ne-Wi-Fi imizila nge esakhelwe Ibhethri elishajekayo ukuthi zingafakwa esikhwameni Ungakhathazeki ukuthi uhambo kuyoba nezinkinga ngokufinyelela kwi-Inthanethi. Kukhona imizila ejwayelekile ukuthi singasetshenziswa exhunywe ugesi leli dolobha lalilihle futhi zisebenzisa ekhaya.

4G kwenethiwekhi

Ngakho umehluko phakathi 3G kusukela 4G? Kuyaphawuleka ukuthi manetha amabili abe kahle ichazwe Ukusabalala izindawo. Esimeni sesibili, inkinga yokwanda eliphansi inethiwekhi, ezimweni eziningi, sebenzisa 4G kuphela emadolobheni amakhulu. EMoscow endaweni eMoscow utawufaka wahlukana. Eyokuqala opharetha ukuthuthukisa uhlobo olusha enamathela, emakethe waqhubeka "megaphone". Futhi manje yena unalo esiphezulu Ukusabalala indawo yonke insimu Russian. Kubalulekile ukuqonda ukuthi 3G / 4G usuke kwenzeka kancane kancane, futhi ngenxa yalokho endaweni Ukusabalala luyokhula isikhathi. Isayithi ngayinye opharetha mobile njalo has ulwazi olufanele mayelana nendawo Ukusabalala.

Le nkampani "MTS" eMoscow nesifunda eMoscow usevikele isekhondi indawo sekugcineni, okuyinto Lwenziwe ngenxa ukuthuthukiswa esebenzayo kwe-network. Le ndawo obuncane opharetha "Beeline", njengoba kwakuhilela "uhlanga" phela.

intengo

Ngakho, ngokungafani 3G kusukela 4G kuyindlela nokwenziwa, kodwa intengo - lena esinye isici esibalulekile endabeni kokubili amanethiwekhi. isivinini 4G ayikho into engavimba-opharetha mobile, futhi kuncike kanjani ukulayishwa inethiwekhi okwamanje. Umsebenzisi angakuthola kwepulani tariff, kuyilapho inani layo kuzoncika bandwidth etholakalayo.

imishini

Wireless 3G noma 4G-Inthanethi ukhonza esikhundleni internet olunezintambo. Lokhu kuyiqiniso ikakhulu lapho olunezintambo abahlinzeki besevisi azitholakali. Ngokwesibonelo, uma ungumnikazi ekotishi noma ifulethi esakhiweni esisha, wena ukufinyelela ezinhle high speed internet awukwazi ubuhlungu. Kulesi simo, ikhambi elingcono kakhulu ukusebenzisa 3G noma 4G-router. Kuyoba usizo hhayi nje ngobe kutawutfutfukisa inhlangano ukusatshalaliswa engenantambo Inthanethi Wi-Fi, kodwa futhi ukuthola ukufinyelela esitebeleni kwi-Inthanethi, lapho uphawu reception, akwaziwa. Ukuze wenze lokhu, sebenzisa i-antenna yangaphandle noma antenna amplifier.

Kuyini 3G?

3G - a wireless technology kunezinzuzo eziningi, uma kulinganiswa nokwenu zezizukulwane zangaphambili. Ezinye izici ukwenza umehluko, ngokukhethekile, ukudluliswa ngesivinini esikhulu, amakhono eziseqophelweni multimedia, kanye kuzula global. Lokhu ubuchwepheshe isetshenziswa ukuxhuma Movie ku-intanethi noma ezinye amanethiwekhi IP ezisekelwe kubathengi waba nethuba ukuveza noma zokuxhumana ividiyo, kanye ukusetshenziswa kwe-Internet futhi amafayela alandwayo.

Kuyini 4G?

Uma sikhuluma 3G Ngokungafani 4G-ke, eqinisweni, umbandela main wukuthi yokugcina isebenzisa entsha esezingeni imvamisa ububanzi, kanjalo alikho emuva kwedivayisi ubuchwepheshe. 4G ihloselwe ukunikeza ukuvikeleka olunzulu zonke IP-based (IP wefoni, amasevisi amageyimu, ukufinyelela broadband, kanye Soxhumanoningi yokusakaza).

4G kanye 3G

Ukuze uqonde kangcono umehluko phakathi kwalezi ubuchwepheshe ezimbili kubalulekile ukucabangela amaphuzu athile.

Iphuzu lokuqala kakhulu kuqhathanisa isivinini. Kukhona kungaba uyibize ngokuthi standard, okuyinto engcono. Esimweni sokuqala, njengoba kushiwo ngaphambili, isilinganiso singamaphesenti encike ngqo kwi inethiwekhi. 4G usebenza ngokushesha izikhathi 10 uma kuqhathaniswa 3G. Konke kuncike imishini osetshenziselwa yokukhulisa amasignali nedatha.

Ukufika kombuso 3G abasebenzisi ukushaya izingcingo ngezwi bese udlulise idatha ngesivinini amandla. Uma kwenzeka lenyuka nge 4G ngesivinini transmission kakhulu, ngaphezu kwalokhu, abathengi bakwazi ukusebenzisa okuqukethwe multimedia ngokuqondile Internet futhi udlale imidlalo inthanethi. Shayela imisebenzi futhi idatha kule futhi kwelinye icala, umsebenzi ngesikhathi esifanayo.

kobuchwepheshe

3G isebenzisa iziteshi idatha kokushintsha inethiwekhi isizinda kanye amaphakheji. iphakethe usuke kuphela esetshenziswa 4G. Uma uqhathanisa throughput kokubili amanethiwekhi, wena ngeke uzizwe yimuphi umehluko. I-4G zonke izingcingo zisebenzisa i-IP wefoni, engatholakali ku 3G.

Bobabili inethiwekhi ukudluliswa kwedatha rate imayelana okufanayo, futhi ezingeni 5-20 Mbit / s.

isiphetho

Yiqiniso, 4G limelela izinto zobuchwepheshe obuphambili ngaphezulu, kodwa ekwenzeni lokho okuhleliwe umnyuziki ingakamiswa kuphelile, ngakho abasebenzisi abakwazi ukujabulela izinzuzo. Njengoba usekelo 3G, 4G ayikahlanganiswa athuthukile ngokwanele ukuba badlulele ezingeni elilandelayo, wonke amasevisi ukuthi kufanele kube atholakale abasebenzisi, kukhona ngendlela efanele usaqala kokusebenza. inethiwekhi isizukulwane yakamuva babe ngaphezulu izici isisindo kungukuthi uphenyo ngokugcwele, futhi imishini yesimanje usuku ngalunye oludlulayo kuba more xaka, ngakho zonke izinzuzo ubuchwepheshe iyoba sobala kuphela emva kwesikhashana, bese sikwazi ukuqhathanisa 3G 4G-Inthanethi ngokugcwele.
