Njani antenna ye modem

Abaninzi kuthi sijongene yokwamkela okulambathayo 3G. enothi ekhaya 3G modem - enye yeendlela kuloo meko. Kwaye akukho kubaluleke kakhulu ukuba isinxibelelanisi kuba kwisixhobo yakho okanye hayi, njengoko siza kunikela nina izisombululo ezizezinye izixhobo, apho, yaye apho akunjalo.

Eriyali ngokuba imodem iyakwazi ngokwandisa umqondiso buthathaka. Masiqalise kunye ndlela elula ukuwenza. Thatha ucingo lobhedu, yaye nibolekisana ezintathu ukuya kwezine ehlabathini ifowuni yakho. Kungcono ukuba bawenze kwincam yayo, ngenxa yokuba kukho ukwamkelwa eriyali eyakhelwe-ngaphakathi.

Ngokuba uvavanyo sibe modem, eyabonisa -107 decibels. Ngokubhijela ucingo lobhedu izinga ebizwa ngokuba "palkomera" lenyuka, ngelixa ubhaliso kwizifundo lanyuka ukuya -101 decibels. Le antenna 3G modem izandla zakho kufuna amanyathelo ecacileyo. Ngapha koko, wena ngokwakho kuya kufuneka ukhethe ubude, ubukhulu kunye nenani amagophe of wire. Umzekelo, ubude okanye coil unako zombini ukuphucula nokunciphisa umgangatho reception uphawu.

Eriyali kuba modem: lesibini ukhetho. Le ndlu ibizwa ngokuba colander okanye epanini. Bonke abalandeli yemifuniselo, apho kwaziswa lithemba ngenxa isantya ufikelelo buthathaka, ndlela wenza uyilo ezahlukeneyo exotic ngomfanekiso neembiza, screens, kunye isidlo satellite. Olu khetho isuntswana ngaphezu ezidlulileyo, kodwa eli-eriyali ye modem uza kufuna ixesha elininzi kakhulu.

Kufuneka kuqatshelwe ukuba ifowuni liquka ulwandiso wire. ubude bayo ngokuqhelekileyo isusela ukusuka eziimitha ezintathu ukuya kwezintlanu. Ekupheleni kukho intwana encinci tape kabini-Amasa apho imodem encamathele kufuphi i window okanye eludongeni. Imiyalelo ikwabonelelwa umenzi isixhobo. Yintshukumo i-eriyali enjalo imodem efanayo kwicingo khetho ukuba kuye kwaxutyushwa ekuqaleni.

Le ndlela ilandelayo - cupping. Okokuqala, oko kudla ngokusetyenziswa womnatha WI-Fi. Ngenxa yale ndlela, iingcibi ikwazile ukwandisa ezi uthungelwano phezu kumgama ozikilometa eziliqela phakathi iindawo zokungena. Ngoko ke, sithatha indawo engenanto ithini uze wenze ezinye izibalo ezilula.

Nanku umzekelo ukubala enjalo. Ubukhulu be Madikane (D) lilingana ngemilimitha ezilikhulu. Kwamaza L _o ngu 143 eemilimitha, ngokulandelelana L _o / 4 ziya kuba malunga nama-36 iimilimitha. Kwamaza L _g ilingana 261 mm, kwaye L _g / 4 ilingana nama-65 iimilimitha. Ngoko ke, kumgama milimitha 65 ukusuka ezantsi yeebhanki zethu senza umngxuma apho Iqinisekile umngxuma eqhelekileyo. Kule waveguide soldered ubude ogama ulingana ngemilimitha 36. Kufuneka senziwe ucingo lobhedu, ogama ubukhulu na ngemilimitha ezimbini.

Ngoku esithathwa osontiweyo kamabonakude intambo, incamathele kuyo Isidibanisi uthi Imigudu ebhankini, yaye kwelinye icala - le isinxibelelanisi modem.

Kwaye ukuba akukho isinxibelelanisi? Kulo mzekelo, ungenza ibattery iyunithi kwaye ufumane okusikrotyana kwibhodi yokulinganisa. Kule soldered wire wasikhusela of omncinci. Ngokwenjenjalo uya kuzisa i-adaptha ukudibanisa ku-eriyali. Kodwa ke kufuneka kwenziwe ngocoselelo kakhulu ukwenzela ukuba kuphulukana usisiqinisekiso modem okanye lokurhoxisa Asinakusebenziseka ngokupheleleyo.
