Yintoni ifowuni 3G, kwaye Kuyinzuzo njani

Sihlala siyashukuma kwihlabathi kweenkcukacha nokuphuma kwemali, ukwenza ezininzi iminxeba yefowuni, akusoloko kwi-ofisini yakho okanye ukude nekhaya, ngendlela enye okanye ngenye xa sijamelene 3G standard (ungayiqondiyo kuba IsiNgesi. "Isizukulwana Okwesithathu"). Makhe sizibuze: "Yintoni na ifowuni 3G?"

EYurophu waqondisa ezizodwa "ukubetha" elikhankanyiweyo umgangatho - UMTS, emele kwizibhambathiso phakathi ngcono umgangatho umgangatho nge nokuba isixa esikhulu camera lwababhalisi GSM. 3G asebenza kuluhlu UHF mayelana 2 GHz ngereyithi data ye 3.1 Mbit / s. Kwiinkonzo ezisisiseko 3G-networks kuthatyathwe ilizwi neenkcukacha zonxibelelwano. ukuqonda ezingundoqo uluhlu lweenkonzo kwindawo yabucala ephantsi, bekhumbula umgangatho edlulileyo, musa yintoni 3G phone namhlanje. Namhlanje ukudluliselwa data inika unxibelelwano njenge umda ishishini ngesantya esiphezulu (i-imeyile, ividiyo inkomfa, ufikelelo olusisiseko zedata, ulawulo bank account), kunye nomdla zobuqu (imidlalo, uthungelwano loluntu, iinkqubo yemultimedia, ukuthenga online). Izinga Transmission nobukhulu bomzimba isantya ehamba ngaso loo nto. Kwimeko lokufumana endaweni - 2048 kbit / s, lo gama i-isantya 3km / h - 348 kbit / s, 120 km / h - 144 kbit / s. Popular nabasebenzisi enjoy unlimited mobile Internet, nelinika kwabo ithuba ethile ngenyanga imali yokuya uthungelwano lwehlabathi. Abaninzi banomdla lo mbuzo: "Indlela engcono ukukhetha umsebenzisi?" Impendulo yalo mbuzo ulula. Okokuqala, ubone ukuba bonelisekile kwindawo yayo ingxelo kusini. Koko ukuhlola rates umnikezeli. Koko wenze isigqibo.

Kodwa 3G intanethi - ntoni na? Hayi nje Pop. Ukuba une-PC, netbook, nencwadi, koko ukudibanisa i uxhulumaniso lwe Wi-Fi ufuna 3G-imodem. Ezinemisebenzi kakhulu-USB-modem, edityaniswe ngqo USB-lezibuko computer. Ngaphezu koko embodiments kunokwenzeka ExpressCard, PCMCIA. Subsequent ingxelo reception yokhetho uphawu ethembekileyo umgangatho kwimigaqo devaysa yayo uluhlu kwamaza, isantya transmission umqondiso. Kaloku, ukuba umboneleli ende elikufutshane ikufutshane. Xa umgama we 10-50 km umsebenzi modem ozinzileyo uya kubonelela kwisixando 3G-eriyali. imikhosi yangaphakathi ukuba 5-10 decibels, kodwa ngamanye amaxesha kufuneka yangaphandle, ezinamandla ngakumbi. Ukuze wenze oku, ukuze kube luncedo 3G Wi-Fi umzila. Nceda uqaphele ukuba ukuze frequency ezintathu bands 3G Internet: 450, 800, 2100 MHz - ekhethiweyo imodem ehambelana ne-eriyali.

Ngokukhawuleza ekuphuhliseni market Smartphones mihla kunye ukuxoxa. Oku "Classic" Soup, obonisa ukuba le foni 3G. Bathi ke, ukongezelela ukuphunyezwa woqhakamshelwano ilizwi, baxhotyiswa ne-in eyakhelwe 3G modem, ukugcina unxibelelwano kunye WWW. Kwi elidlula ngohlangothi inkqubela HTC kunye Samsung (platform Android) izixhobo kunye Apple (iOS operating system).

Ngoku zithanda phakathi abasebenzisi izixhobo yeselula screens ezinkulu - tablets. Le fowuni kuqikelelwe esihlangeneyo 3G imodem (nekucetyiswa, ingakumbi xa umenzi - China) - ukuba akunjalo, ngoko ke kufuneka ukuba ayithenge. Kusenokwenzeka ukuba "ukusilela" abaqhubi ngokwahlukileyo wathenga modem.

Dialectics of revolution yenzululwazi kunye nobuchwepheshe, owayebaqonda zobunzululwazi lo mbuzo: "Yintoni na 3G ifowuni" kukhokelele kwisigaba esilandelayo - 4G. Phezu kwako amandla ezikhoyo, 3G - kuphela elinye inqanaba lophuhliso lwehlabathi. 4G nobuchwepheshe, nto leyo eye elinye igama - lte (Long TermEvolution), ukuphucula uthungelwano ezikhoyo, ukwandisa isantya nomthamo ukwaziswa. ENorway naseSweden ukuba ngoovulindlela ubuchwepheshe obutsha. Uphuhliso olulolunye akukho enye: abaniki isiseko Russian "Beeline" kunye MTS, "megaphone" sele uqalile umsebenzi ngokwesivumelwano samazwe kwiinkonzo zonxibelelwano kwi-standard lte.
