USB-imodem for ukuhlela standard

Ngophanya nje lweliso, kusenokubonakala ngathi ukuba USB-iimodem Bambalwa kakhulu abantu kufuneka. Nangona kunjalo, oku elahlekisayo. Nantsi nto. Eneneni, uninzi leyo ngoku emalikeni kwezixhobo network lokunxibelelana ngekhompyutha kusetyenziswa Ethernet interface. Isizathu kukuba banal: lo mgangatho ifuna uqhagamshelwano ngentambo kwi ISP, esibonakala yi-high speed ukufikelela kwi- Internet ehlabathini. Kodwa ezahlukeneyo USB-iimodem bakholisa ukusebenzisa indlela unxibelelwano zintambo, leyo, yeha, ayahlukanga ukusebenza asifani. Noko ke, bafumana abathengi zabo.

Internet emoyeni

Loo nqaku akuthethi ukuba abstract kakhulu, makhe sijonge kwi-USB-iimodem zenzelwe ukuba basebenze uthungelwano nge-mashishini. Konke oku kungentla ngokupheleleyo isebenza umgangatho GSM.

Ngoku ethandwa abaninzi abohlukeneyo namacebo aphathekayo - laptops, netbooks, amacwecwe, njl Ngamanye amazwi, bonke abo banako kubizwa ngokuba mobile .. Kucacile ukuba "ukuhamba" kunye "Internet kwi wire" - amagama ezingahambelaniyo. Ukusombulula le ngxaki, abasebenzisi abaninzi baye baqalisa ukunikela ngeenkonzo ukufikelela kwi-Internet ngaphandle. Nje ngokwaneleyo ukuze ufumanise ukuba ziintoni USB-imodem, ukuthenga imodeli yakho ozithandayo, uze basayine imvumelwano kunye nomboneleli-nkonzo ochaphazelekayo. Akukho iingcingo ezihamab phantsi iyafuneka. Uthungelwano ke yonke indawo esisigxina umqondiso izikhululo esisiseko.

Ingxaki choice

Kakade ke, khetha USB-imodem abanalo kwimbonakalo (nangona oku kubalulekile), makuthathelwe ingqalelo iimpawu zayo.

Ngoko ke, lo imodem nge unako ukusebenza kwenye kweendlela ezintathu: a elisezantsi zesantya 1x (ukuya ku 153 kbps); Isantya esiphakathi 3G (ukuya ku 3.1 mbps) kunye ngesantya esiphezulu (ukuya kwi 14.7 mbps). Ukuhambelana igcinwa ukusuka phezulu ukuya ezantsi, okt isixhobo exhasa mbps-14, oko alwa kakuhle kunye neminye imigangatho ezimbini. kufuneka bazi phambi kokuba kuthengwe i modem ekhethiweyo yi umqhubi isebenza kunye nawuphi umgangatho.

Ngamanye amaxesha igcine ukunika ukuthenga msindo lwe USB-modem. Esi sixhobo kuyimfuneko kunokwenzeka ukuba uceba ukusebenzisa ukufikelela beradiyo kwindawo umqondiso buthathaka. Kanye efakwe kwi modem, abambe amaza kwaye liziphose kuwo kummandla eriyali yayo eyakhelwe-ngaphakathi, ngoko ekuphuculeni unxibelelwano. Ukusebenza ixhomekeke eziliqela iparameters. Ngokuba ukusetyenziswa umile kusengqiqweni ngakumbi ukuthenga i modem kunye yangaphandle eriyali isinxibelelanisi.

Ngokufuthi, abavelisi bazama ukutsala ingqalelo iimveliso zabo ngokunikela isisombululo kunye ubuchule ukudibanisa memory amakhadi, eyenza i modem ibe USB flash drive. phantse Le Ukongeza ayinyuki iindleko zizonke, wafuna-emva kakhulu.

Xa uthenga i modem, kucetyiswa ukuba khangela ukuba imizuzu eli-10-15. imodeli abangaphumelelanga ukuba eli xesha babe nexesha lokuba abe shushu kakhulu.

Icwangcisa USB-modem

Njengoko kukhankanyiwe ngasentla, le ngxaki iphambili iifowuni ezisebenza ngaphandle kweengcingo - isantya phantsi. Nokuba bathi 14.7 mbps alinakuzuzwa - ababoneleli nilwamkelele ilize abonisa "phambi" phambi imivo. Okunye ukuphucula eli nani linokuba kuphunyezwa ngokubeka. Okokuqala, kufuneka amisele inqanaba uphawu - kunokwenzeka ukuba usebenzise inkqubo Axesstell. Ukuba inqanaba yayo ayanelanga (ngakumbi «- 100dB»), kuyimfuneko ukudibanisa i-eriyali lwangaphandle okanye umqondiso amandla. Kuphela koko uyakwazi ukuqhubeka ukuqwalasela software, kungenjalo andiyi kubuzisa ukuphucuka okukhulu. Indlela elula ingachaphazela ukusebenza ifowuni kunokwenzeka ngokuthi kokufaka inguqulelo umqhubi yakutshanje. Ezinye iimpawu ifuna ulwazi oluthile entsimini nge-modem, ngoko ziqwalaselwa ngokweenkcukacha namaqonga eengxoxo.
