I-GSM900/WCDMA2100 2W Iziphindaphinda zebhendi ezikhethiwe

Kingtone Repeaters
Uhlelo lwe-Kingtone luklanyelwe ukuxazulula izinkinga zesiginali yeselula ebuthakathaka, eshibhe kakhulu kunokwengeza i-Base Station entsha (BTS).Ukusebenza okuyinhloko kohlelo lwe-RF Repeaters ukuthola isignali yamandla aphansi evela ku-BTS ngokusakazwa kwamafrikhwensi omsakazo bese idlulisela isignali ekhulisiwe ezindaweni lapho ukutholakala kwenethiwekhi kungenele.Futhi isignali yeselula nayo iyakhuliswa futhi idluliselwe ku-BTS ngendlela ehlukile.

Isiphindaphinda ngocingo
Lokhu kusetshenziselwa ukwandisa ububanzi bezimpawu zocingo kulayini wocingo.Asetshenziswa kakhulu kuma-trunklines aphatha izingcingo ezikude.Kulayini wefoni we-analog ohlanganisa ipheya yezintambo, uhlanganisa isekethe ye-amplifier eyenziwe ngama-transistors esebenzisa amandla asuka kumthombo wamanje we-DC ukukhulisa amandla esignali yomsindo yamanje eshintshanayo kulayini.Njengoba ucingo luwuhlelo lokuxhumana lwe-duplex (bidirectional), izintambo ezimbili ziphethe amasignali amabili omsindo, eyodwa iya ohlangothini ngalunye.Ngakho-ke abaphindayo bezingcingo kufanele babe ngamazwe amabili, bakhulise isignali kuzo zombili izinhlangothi ngaphandle kokubangela impendulo, okwenza kube nzima ukuklama kwabo kakhulu.Abaphinda ngocingo babewuhlobo lokuqala lokuphinda futhi bekungezinye zezinhlelo zokusebenza zokuqala zokukhulisa.Ukuthuthukiswa kweziphindaphinda ngocingo phakathi kuka-1900 no-1915 kwenza isevisi yocingo yebanga elide yenzeke.Kodwa-ke izintambo eziningi zokuxhumana manje seziyizintambo ze-fiber optic ezisebenzisa iziphindaphinda ezibonakalayo (ngezansi).

Isiphindi seselula
Lesi isiphindaphinda somsakazo sokuthuthukisa ukwamukela komakhalekhukhwini endaweni elinganiselwe.Idivayisi isebenza njengesiteshi esincane seselula, esinothi oluqondisayo lokwamukela isignali kusuka kumbhoshongo weselula oseduze, i-amplifier, kanye nothi lwasendaweni ukuze isakaze kabusha isiginali kumaselula aseduze.Ivamise ukusetshenziswa ezakhiweni zamahhovisi ezimaphakathi nedolobha.
 

Isici esiyinhloko

Izici Eziyinhloko
◇ I-PA ephezulu yomugqa;Ukuzuza kwesistimu ephezulu
◇ Ubuchwepheshe be-ALC obuhlakaniphile
◇ I-duplex ephelele kanye nokuhlukaniswa okuphezulu
◇ Ijika lesihlungi esicijile
◇ Ukusebenza okuzenzakalelayo ukusebenza okulula
◇ Idizayini ye-Modular kulula ukuyigcina
◇ Isilawuli kude/gada/i-alamu nge-RF MODEM noma i-Ethernet
◇ IP65 idizayini ye-chassis yohlelo lokusebenza lwangaphakathi nangaphandle

Uhlelo lokusebenza&izimo

Izinhlelo zokusebenza
Ukwandisa ukumbozwa kwesignali yendawo eyimpumputhe yesignali yokugcwalisa lapho isignali ibuthakathaka
noma engatholakali.
Ngaphandle: Izikhumulo Zezindiza, Izifunda Zezokuvakasha, Izifundo Zegalofu, Imigudu, Amafekthri, Izifunda Zezimayini, Imizana njll.
Ngaphakathi: Amahhotela, Izikhungo Zemibukiso, Amagumbi angaphansi, Ukuthenga
Izitolo ezinkulu, Amahhovisi, Izitolo Zokupakisha njll.
Isebenza kakhulu esimweni esinjalo:
Ophindayo angathola indawo yokufaka engathola isignali emsulwa ye-BTS ezingeni eliqinile ngokwanele njengoba Izinga le-Rx kusayithi lokuphinda kufanele libe ngaphezu kuka- -70dBm;

Futhi ingahlangabezana nemfuneko yokuhlukaniswa kwe-antenna ukugwema ukuzizulisa.
