USB-modems kwa CDMA muyezo

Koyamba zingaoneke kuti USB-modems ndi ochepa kwambiri anthu. Komabe, izi wonyenga. Apa pali chifukwa. Ndithudi, ambiri amene tsopano pa msika zida maukonde kulankhulana ndi kompyuta ntchito Efaneti mawonekedwe. chifukwa ndi banal: mfundo imeneyi amafuna kugwirizana chingwe ku ISP, omwe amakhala ndi mwayi mkulu-liwiro ku Internet lonse. Koma zosiyanasiyana USB-modems amakonda kugwiritsa ntchito njira kulankhulana mafoni, chimene, tsoka, sasiyana ntchito mofanana. Komabe, iwo kupeza ogula awo.

Internet mu mlengalenga

Nkhani kuti si kuti nawonso umboni, tiyeni tiyang'ane pa USB-modems yadaikidwa kuti ntchito Intaneti ya CDMA-ntchito. Onse a pamwamba pang'ono lokhudza GSM muyezo.

Tsopano wotchuka kwambiri ndi kunyamula zipangizo zosiyanasiyana - Malaputopu, netbooks, mapiritsi, etc. M'mawu ena, onse amene angatchedwe mafoni .. Ndi bwino ndithu kuti "sayenda" ndi "Internet pa waya" - mfundo atakwatirana. Kuti athetse vutoli, ntchito ambiri anayamba kupereka ntchito Intaneti wirelessly. Monga mokwanira kufufuza kodi USB-modems, kugula chitsanzo mumaikonda, kenako kulemba pangano ndi athandizi zogwirizana. No cabling chofunika. maukonde ndi kulikonse atathana chizindikiro okwerera m'munsi.

Vuto wosankha

Ndithudi, kusankha USB-modems alibe maonekedwe (ngakhale kumathandizanso), ndi kutenga nkhani zochititsa.

Choncho, CDMA modems umagwira ntchito imodzi modes atatu: liwiro otsika 1x (mpaka 153 kbps); sing'anga liwiro 3G (mpaka 3.1 Mbps) ndi liwilo (kwa 14,7 Mbps). Ngakhale anakhalabe kuchokera pamwamba mpaka pansi, mwachitsanzo chipangizo zothandiza 14 Mbps, izo amadwala bwino ndi mfundo zina ziwiri. ayenera kudziwa pamaso kugula ndi modemu osankhidwa ndi woyendetsa ntchito ndi muyezo uliwonse.

Nthawi zina masitolo kupereka kugula mkuzamawu wa USB-modemu. chipangizo Izi ndi zofunika kukachitika kuti ngati mukufuna kugwiritsa ntchito mwayi mafoni ku dera ofooka chizindikiro. Kamodzi anaika pa modemu, izo limagwira mafunde, ndiponso limafotokoza iwo pafupi ndi mlongoti ake anamanga-, potero kuwongolera kulankhulana. Mwachangu chimadalira pa magawo angapo. Ntchito n'kupuma zambiri zomveka kugula modemu ndi cholumikizira kunja mlongoti.

Nthawi zambiri, opanga akuyesera kuti akope tcheru kuti zinthu zawo ndi kupereka yankho angathe kulumikiza makadi zinthu, zomwe zimapangitsa modemu mu USB kung'anima galimoto. Kuwonjezera izi pafupifupi sakhala kuonjezera ndalama okwana kwambiri anafuna-pambuyo.

Pogula ndi modemu, izo tikulimbikitsidwa kuti fufuzani kwa mphindi 10-15. Atalephera chitsanzo nthawi ino ndi nthawi yokhala otentha kwambiri.

Kuika USB-modemu

Monga tanena vuto lalikulu zipangizo mafoni - otsika liwiro. Ngakhale ankati 14,7 Mbps mumangire - wosamalira sikuli chabe amasonyeza "" pamaso pamaso manambala a. Mwina kusintha chithunzi ichi chingapezeke mwa atakhala. Choyamba, muyenera kudziwa mlingo wa chizindikiro - n'zotheka ntchito pulogalamu Axesstell. Ngati mlingo wake ndi osakwanira (more «- 100dB»), m'pofunika kugwirizana ndi mlongoti kunja kapena mphamvu chizindikiro. Only ndiye inu mukhoza chitani sintha mapulogalamu, mwinamwake iwo sadzakhala kubweretsa kusintha kwambiri. Chophweka njira bwanji ntchito chipangizo ndi zotheka ndi khazikitsa Baibulo atsopano a dalaivala. zina amafuna kudziwa zenizeni m'munda wa CDMA-modemu, kotero iwo tikambirana mwatsatanetsatane maonekedwe zokambirana.
