Yintoni ngombhobho 3G modem

msindo uphawu 3G-imodem amandla hayi kakhulu kukhule nesantya kwezibonelelo womnatha, kodwa kwakhona ukunika umqondiso womelele ngakumbi. Maxa wambi yokugqibela kubaluleke ngakumbi. Kunzima ukuba uphikise nesibakala sokuba kulula kakhulu ukuba ukusebenza kunye Internet, leyo, nangona oko akuthethi ukunika ufikelelo ophezulu kakhulu ngesantya, kodwa silahlekelwe umqondiso kwisiseko sesikhululo.

Ngokusesikweni, Kakade ke, phambi kokuba usebenzise amandla imodem, kuhle ukufumanisa ukuba yintoni kanye ezibangelwa nomgangatho ophantsi isixhobo network. Oku athathe isisombululo elungeleleneyo eza kwenza ngendlela kangangoko ukoyisa le ngxaki. Noko ke, ngokufuthi inkcazelo ngqo oku akusoloko kusenzeka, ngoko lo mshini 3G-modem, njengokuba umthetho, sisixhobo esibanzi-spectrum - uhlobo lwe ukusilela.

Kutheni Internet ayisebenzi

Ukuqinisekisa amazwi akhe, nika uluhlu lwe wonobangela emikhulu echaphazela umgangatho umsebenzi modem wireless:

- Le fowuni ibhaqa akukho ngqo kwaye iboniswe ukusuka yenjongosenzi isiqabu okanye izakhiwo umqondiso. Ngenxa co edalwayo kunye ubugqwetha, kwimeko enjalo ukuphumeza isantya esiphezulu kunye uxhulumaniso ezinzileyo akusoloko kusenzeka. Okunye ukusombulula le ngxaki inokupheliswa ngamandla modem.

- izixhobo kwisiseko sesikhululo (operator Tower) na kwi enkulu kakhulu umgama ukusuka kwindawo siwamkelayo umyalezo. Ngoko ke kukho ukuhla yendalo amandla alo ngenxa iimpawu emoyeni. Kule meko amandla imodem kunye ukusebenza ngokwaneleyo, bebenoyilungisa ngokupheleleyo zonke iingxaki.

- I elikufutshane kwisiseko sesikhululo kwi efanayo ixesha bakhonza ngabathengi ezininzi kakhulu, ngoko izibonelelo zalo azonelanga ukunikezela inkonzo esemgangathweni.

Solutions ukuphucula unxibelelwano

Nangona yobuninzi neziphakamiso oluvela kwisiseko sesikhululo reception umqondiso, bonke bephela lungahlulwa-hlulwa ibe ngamaqela amahlanu:

- Ukusetyenziswa kwe-eriyali lwangaphandle. Oku kufuna ukuba kuyilo modem wasebenzisa kucingelwa uqhagamshelo eriyali iadaptha - ekuthiwa-pigtail. Umntu ongakwazi ngokuchanekileyo ngelotha wesiphaluka chip ngokuzimeleyo sidityaniswe kwifowuni isinxibelelanisi, nangona kunjalo, ukubonakala kuguga.

- Application sesimangalo modem uyilo ezizodwa, ayidingi izihlanganisi (noncontact).

- Ukufakwa kwefowuni ibhokisi evaliweyo alithwale kuphahla okanye olungaphambili.

- ngelotha iinxalenye kwisekethe yesixhobo.

- Amandla uhlobo olusebenzayo lwe modem.

Izisombululo ubuncinane olusebenzayo - yesibini neyesine. Usebenziso oluqhelekileyo lwe-eriyali lwangaphandle kunye pigtail. Iindleko izixhobo ezongezelelweyo liphantsi kakhulu, kunye nokufakwa kunye olunye utshintsho kube lula eyenziwe ngokwakho. Ngenxa iinzuzo eriyali ezahlukeneyo, kunokwenzeka ukuba ukukhetha simse, ebonisa iziphumo ezingcono kwimeko nganye.

Kodwa ke indawo yokugqibela engaqhelekanga kwabaninzi, kodwa lo mgaqo emva msindo esebenzayo, iye lwaziwa ixesha elide, nto iye isetyenziswe ngempumelelo-mveliso eyahlukeneyo. Nkqubo zilandelayo: on olungaphambili ebekwe eriyali lwangaphandle nto ibonakaliswa ukusuka phezulu ukuya ngokolwalathiso na kwisiseko sesikhululo; nge intambo aqhelelkileyo kunye ukuvimba uphawu 50 ohms isignali nakwesiphi sixhobo ngombhobho - 3G-zabaphindayo (zabaphindayo). busebenze yayo yangaphakathi ukwandisa ngobunzulu umqondiso eriyali zifakiwe kwaye idluliselwe phezu USB-USB okanye sokuquqa kwerediyo kule khompyutha. Bobubi ke iindleko eziphezulu isigqibo esinjalo, phantse-4 phinda ixabiso nayiphi na kwezi ndlela eseleyo.
