Kodi mkuzamawu kwa 3G modemu

mbendera mkuzamawu kwa 3G-modemu chimathandiza osati kwambiri kuonjezera ndi liwiro chuma network komanso kupereka chizindikiro wolimba kwambiri. Nthawi zina yotsirizira n'kofunika kwambiri. N'zovuta kutsutsana ndi chakuti zimakhala zosavuta kugwira ntchito ndi Internet, kumene ngakhale sasamalira kwambiri liwiro mwayi, koma sasiya mbendera siteshoni m'munsi.

Choncho, ndithudi, musanayambe kugwiritsa ntchito mphamvu kwa modemu, ndi bwino kudziwa zimene ndendende chifukwa cha khalidwe osauka a zida maukonde. Izi kutenga njira moyenera kuti zidzathandiza njira mulingo woyenera kuthana ndi vutoli. Komabe, nthawi zambiri chotero tanthauzo yeniyeni Sizotheka, kotero mkuzamawu wa 3G-modemu, monga ulamuliro, ndi yotakata-sipekitiramu chipangizo - ndi mtundu zodzikhululukira.

Chifukwa Internet sizikuyenda

Kutsimikizira mawu ake, kupereka mndandanda wa zimayambitsa zikuluzikulu zokhudza khalidwe la modemu mafoni ntchito:

- chipangizo The detects palibe mwachindunji ndipo ananyezimiritsa ku chinthu thandizo kapena nyumba tenepa. Popeza co-mayamwidwe ndi kupotoza, zimenezo kukwaniritsa liwilo ndi kugwirizana khola Sizotheka. Mwina vutoli akhoza mphamvu modemu.

- siteshoni m'munsi zipangizo (nsanja woyendetsa) chiri chachikulu kwambiri patali ndi kulandira malo. Choncho pali kuchepa zachilengedwe mphamvu yake chifukwa katundu wa mlengalenga. Imeneyi ndi mphamvu ya modemu ndi dzuwa okwanira, akhoza kwathunthu mavuto onse.

- The yapafupi siteshoni m'munsi pa nthawi yomweyo anali ndi makasitomala ambiri, choncho zinthu zake ali wokwanira msonkhano wabwino.

Malangizo Othandiza muzilankhulana bwino

Ngakhale kuchuluka kwa bwana pa kukhathamiritsa siteshoni chizindikiro phwando m'munsi, onse a iwo akhoza kugawidwa m'magulu asanu:

- The ntchito mwayi mlongoti kunja. Pamafunika kuti kamangidwe ka modemu ntchito ankaganiza mlongoti adaputala kugwirizana - otchedwa pigtail. Munthu amene angathe molondola soldering Chip dera akhoza mosadalira kuti olumikizidwa kwa chipangizo cholumikizira Komabe, maonekedwe chatsitsa.

- Tingachigwilitswe mkuzamawu Modems kapangidwe wapadera, sikutanthauza zolumikizira iliyonse (noncontact).

- Malo chipangizo mu bokosi womata ndi kupita nako padenga kapena wapakamwa.

- soldering zigawo zikuluzikulu za dera chipangizo.

- Mphamvu mtundu yogwira modemu.

Njira zosachepera zothandiza - wachiwiri ndi wachinayi. The ntchito ambiri ndi mlongoti kunja ndi pigtail a. Mtengo wa zida zina ndi wotsika, ndi unsembe ndi kusintha zina n'zosavuta wekha. Popeza akupeza osiyana mlongoti, n'zotheka kusankha yabwino yothetsera, kusonyeza zotsatira zabwino pa nkhani iliyonse.

Koma mfundo yomaliza ndi achilendo ambiri, koma mfundo za mkuzamawu yogwira, wakhala kudziwika kwa nthawi yaitali, wakhala bwinobwino ntchito m'mafakitale zosiyanasiyana. Chiwembu ndi izi: pa wapakamwa woyikidwa kunja mlongoti amene zochokera motsatira dongosolo ku siteshoni m'munsi; kudzera mkulu pafupipafupi chingwe ndi impedance khalidwe la 50 ohms chizindikiro umaperekedwa kwa mkuzamawu chipangizo ndi - 3G-repeater (repeater). circuitry kwake kwa mkati kuonjezera mphamvu ya analanda mlongoti chizindikiro ndiponso opatsirana pa USB-chingwe kapena pafupipafupi wailesi kompyuta. The kuipa ndi kukwera mtengo kwa kusankha zimenezi, pafupifupi nthaŵi 4 mtengo uliwonse wa options otsala.
