Indlela ukwandisa 3G CDMA isivinini imodemu ejwayelekile?

Kungabonakali, okuhamba ngezidladla zakho elithambile, sekuyisikhathi ngesivinini kanye yamanani ongaphakeme ukufinyelela i-Inthanethi. Manje akekho kuyoba ukufinyelela umangale ukuthola inethiwekhi global ngesivinini megabits phezu 100, ikakhulukazi imiphakathi yasemadolobheni amakhulu. Nokho, konke lokhu kwenziwa ngosizo izintambo: imigqa optical noma ezivamile wiring amahanisi - ngokuyisisekelo uyefana. Kodwa izakhamuzi izifunda nasezindaweni zasemaphandleni ezikude lapho kungekho abahlinzeki ikhebula umugqa uxhume ku-Inthanethi kufanele okuqukethwe inikeza opharetha engenantambo. rates abo siphakeme kakhulu kunalokhu futhi ijubane ingezansi. Ngokwesibonelo, omunye eziphambili kakhulu nge-CDMA Rev.B ubuchwepheshe kwakuthiwa evumela ijubane ukufinyelela megabits 14 kuphela ukuthi izakhamuzi -. "Izolo" Kuyaqondakala ukuthi izimo ezinjalo, umsebenzisi we-Inthanethi engenantambo ngamunye ungathanda ukwazi indlela ukwandisa ijubane 3G imodemu.

Yilokho sikhuluma namuhla, kodwa njengesibonelo, cabanga nge-CDMA EVDO modems. Nakuba zikhona izinguqulo CDMA eziningana, ezingafani ngokuyinhloko imvamisa yenethiwekhi, okukhulunywa ngaso kulesi iphepha, esekelwe indlela kunoma yimuphi umsebenzisi ofuna ukwandisa ijubane 3G imodemu.

Silindele imibuzo, touch kancane ku izisekelo ezicatshangelwayo. Okokuqala, yimuphi umhlinzeki tariff ncazelo ibonisa ijubane ukufinyelela kwenethiwekhi, isibonelo, kuze 3.1 Mb / s. Abasebenzisi okokuqala ukuxhuma kwi-Inthanethi engenantambo, ngizibuze ukuthi kungani hhayi 3.1, kodwa ngisho 2 megabit ungakwazi ukuthwebula ezingavamile kakhulu. Kukhona nkohliso: isiqalo "phezulu" buyafaneleka ngokugcwele, maye. Nokho, akukho lutho kuvimbela siqonde impikiswano futhi baqonde indlela ukwandisa ijubane 3G imodemu kuya kungenzeka esiphezulu, kulapho ukuthi ungakwenza kunoma ubani kunikezwa yokwenza kanjalo.

Okwesibili, ijubane-Inthanethi engenantambo akasoze uzinze:-ke "sintanta" kusuka ihora kuya hora. esiteshini ngasinye umbhoshongo inezinga esimisiwe yayo wokuxhumana, nakuba mikhulu. Subscribers, uxhumekile iphuzu elithile ngesikhathi yahlukanisa leli isilinganiso ndawonye njengoba orange. Ngakho, impendulo yokuqala umbuzo kanjani ukwandisa isivinini imodemu 3G, CDMA ukusebenzisa imodemu ku Ukusabalala indawo esiteshini okungenani ukulayishwa ngesikhathi esifanele. Ngamanye amazwi, izinga kuyoba ephakeme ezindaweni ongaphakeme ukwanda kwabantu abathathu ekuseni kuka maphakathi nedolobha elikhulu esikhathini ibhizinisi.

Hhayi-ke, ake ushiye wedwa imfundiso yokuziphendukela futhi asho ukuthi yiziphi nalapho kudingeka "hlasi" ukufeza imiphumela oluvelele. Kanjani ukuze kusheshiswe 3G imodemu? Easy! Kuye kwaphawulwa ukuthi onobuhle ezahlukene modems ukubonisa amazinga ehlukene, ceteris paribus. Ukuqaliswa iyunithi transceiver, ukubekwa ergonomic izingxenye yangaphakathi nomthelela kakhulu umphumela. Ngokwesibonelo, amanye amamodeli ngemuva kwamahora 2-3 wokusebenza kakhulu heats bese iqala ukuba afiphale, okungukuthi ngokushesha zile ngesivinini ishadi. Hlola imisebenzi imodemu - ke kufanele lizwakale linemfudumalo, kodwa hhayi ashisayo.

Noma yimuphi imodemu USB 3G ibusa port ezithile yamanje. Ngaphezu kwalokho, ngokuvamile 500 ma. Ukuze USB 2.0 ejwayelekile, lokhu kumane nje umkhawulo. Ngakho-ke, uma umuntu USB ihabhu ukuxhuma imodemu futhi kunoma iyiphi enye idivayisi, amandla Akusenele ezithinta umsebenzi. Wena matasa ezingaphezu kwesigamu nezixhumi-USB? Kulokhu, udinga ukuthenga ihabhu-hub nge sangaphandle ugesi. Kungenjalo: ingabe kuvunyelwe ukuxhuma imodemu nge-Y-ikhebula. Anakho kuphela ezintathu: ezimbili afakiwe izixhumi kwi computer, kwathi omunye eya imodemu.

Uma namanje abaqondi ukuthi ukwandisa ijubane 3G imodemu, isinyathelo esinqala: ukufaka enothi lwangaphandle. Ukuphakama lapho ungakwazi pick it up, kukhawulela ikhebula -. Ubude baso akufanele budlule 10 m akuyona ekulondolozeni kuwufanele, ukuthenga izinga phezu ikhebula! By endleleni, ungakhohlwa Orient antenna kuya nesiteshi.

Kuyasiza ukuba ubuyekeze umshayeli imodemu nokwandisa uxhumano nge isimiso esikhethekile.
