Uma i-dacha yakho ingekho kumbhoshongo womsakazo, kufanele wenze imizamo emikhulu ukuthatha noma ukushaya ucingo noma uxhumane ne-intanethi. Kungenzeka ukuthi usuvele uhle kakhulu. Ngaphandle kokuxhumana kwamaselula kanye nenethiwekhi yomhlaba wonke esikhathini sethu kunzima ukucabanga okungenani usuku olulodwa, futhi e-dacha siphila ngezinye izikhathi ngesonto, inyanga noma ngisho nonyaka wonke wehlobo. Ngakho kanjani ukuxazulula le nkinga? Kulula kakhulu - udinga i-signal amplifier yenethiwekhi yakho yeselula.
I-booster cell phone booster isebenza kanjani ifoni?
Le divayisi iyisisetshenziswa esinama-antenna amabili (angaphandle nangaphakathi), ikhebula le-RF kanye ne-repeater. I-amplifier efakwe ngaphakathi endlini, futhi kuphela i-antenna yangaphandle ifakwe ophahleni noma udonga oluvela ngaphandle.
Ukuphindaphinda kusebenza ukuqinisekisa ukuxhumana okubili. Iguqula isignali eshintshayo futhi ebuthakathaka ye- modem ibe yinto enhle neyethembayo. Ngakho-ke, isibonakaliso se-signal sinikeza indawo yokufakaza ngesignali ehlala njalo kuyo yonke indawo yekhaya lakho leholide .
Ungakhetha kanjani i-amplifier yesignali yesignali?
I-GSM-signal amplifier yokuxhumana kwamaselula noma i-antenna ye-3-G? Yini ongayikhetha? I-repeater (noma iphindaphinda) GSM iklanyelwe ukuthuthukisa ikhwalithi yokwamukela yesignali yeselula. Ukukhetha imodeli enhle kusukela enombolweni enkulu etholakala emakethe yanamuhla kuyadingeka, ngokusekelwe ezidingo zabo kanye nemibandela yokusebenza kwayo okuhleliwe.
Okokuqala udinga ukunquma izinga lokuxhumana kwamaselula. Khetha ukuthi yiziphi izinsizakalo ozidingayo - Inthanethi yeselula, izingcingo zezwi. Uma udinga ukuthuthukisa ikhwalithi yokuxhumana, bese udinga ukuphindaphinda kwe-GSM, kodwa uma ufuna ukwandisa ijubane le-inthanethi, awukwazi ukukwenza ngaphandle kwe-antenna enamandla kakhulu ye-3-G.
Kudingeka ucabangele ukuhambisana nokugcinwa komsebenzi womqhubi womphindisi. Ngakho, kubhalisile kwinethiwekhi ye-Tele2, i-repeater iyadingeka ngokusekelwa kwezinga le-GSM-1800.
Uma udinga ukuxazulula izinkinga ezimbili ngesikhathi esisodwa, udinga ukuphindaphinda kabili-band GSM / 3-G.
Yikuphi ukukhulisa isignali yamaselula okungcono?
Ngaphambi kokuthenga nokufaka i-amplifier, udinga ukukala isignali yenethiwekhi yeselula namadivaysi amaningana ehlukene ephathekayo ukuze ucabangele umehluko obonakalayo ekuzweleni kwama-antenna amafoni. Lokhu kuzokuvumela ukuba ukhethe ngokucacile isici sokukhulisa se-repeater. Landela le iphethini: isimo esibi nakakhulu, isibonakaliso esinamandla kakhulu, okusho ukuthi kufanele sibe nenzuzo enkulu.
Ukuze unqume i-CU edingekayo (inzuzo), udinga ukwenza isilinganiso ngaphakathi nangaphandle kwendlu. Uma endlini ubona izigaba ezingu-1-2, futhi emgwaqweni - isilinganiso esiphelele, udinga i-amplifier nge-KU ka-65 dB noma ngaphezulu. Futhi, ngisho noma ubona emgwaqweni ukuthi isibonakaliso sibuthakathaka, khona-ke i-amplifier KU akufanele ibe ngaphansi kuka-75-85 dB.
Kunamamodeli we-amplifiers ane-CU engaphansi kuka-60 dB. Azinconywa ukuthi zisetshenziswe kunoma yiziphi izimo, njengoba zinganikeli umphumela ojwayelekile futhi aziwona amadivayisi awusizo.
Kanti futhi, lapho uthenga isignali yamangqamuzana weselula, udinga ukwazi indawo yendlu yakho ukuze unqume amandla okuphindaphinda. Indawo enkulu, amandla amakhulu kufanele abe.
I-amplifier evamile ye-100 mW iyakwazi ukukhulisa isignali ensimini kuze kufike kumamitha ayi-square-skwele, kepha ukuphindaphinda ngamandla ka 300 mW noma ngaphezulu kunconywa ukuba kusetshenziswe emakamelweni anezindawo ezingu-600-800.
Ngaphezu kwalokho, ukuthi udinga ukukhetha i-repeater enhle, kudingeka uqiniseke ngekhwalithi ye-antenna yangaphandle nekhebula. Lokhu kuzoqeda ukulahlekelwa amandla namandla omsakazo we-radio ngenkathi kudluliselwa kuwo kusukela kumphindaphindi kuya kuma-antenna angaphakathi okusabalalisa.
Futhi elinye iphuzu elibalulekile - ukufakwa kwe-amplifier. Kungcono ukubeka lolu daba kubachwepheshe, ikakhulukazi kusukela kulokhu ungasebenzisa isevisi yewaranti uma kwenzeka izinkinga, ngenkathi ufake i-amplifier ngokwakho, uthatha umthwalo ogcwele ngokwakho.
