Ukufinyelela Ikhebula FSR: Ukwamukela isignali ye-BTS nge-coupler eqondile evaliwe ku-BTS (Kunconyiwe);2. Ukufinyelela Okungenantambo FSR: Ukuthola i-BTS sig...

20W GSM900MHz Air Coupling Frequency ShiftingOphindayoyakhelwe ukuxazulula izinkinga zesiginali yeselula ebuthakathaka, eshibhe kakhulu kunokwengeza i-Base Station entsha (BTS).
 
Ngokwendlela yokuthola isignali ye-BTS yiYunithi Yokunikela, izinhlobo ezimbili zeFSR ziyatholakala:
1. Ukufinyelela Ikhebula FSR: Ukwamukela isignali ye-BTS nge-coupler eqondile evaliwe ku-BTS (Kunconyiwe);
2. Ukufinyelela Okungenantambo I-FSR: Isignali yokwamukela ye-BTS nge-Donor Antenna (isebenza uma kungekho ulayini wokubona ongabukwa phakathi kweYunithi Yomnikeli kanye Neyunithi Ekude njengoba Iyunithi Yomnikeli ifakwe kumbhoshongo we-BTS).
 

Futhi zombili izinhlobo ze-FSR zingahlelwa zibe izigaba ezincane ezi-2 njengokutholakala kwefrikhwensi yesixhumanisi:
1. I-In-band FSR: Ifrikhwensi yesixhumanisi ingaphakathi kwebhendi yokusebenza ye-BTS;
2. I-FSR Engaphandle Kwebhendi: Ifrikhwensi yesixhumanisi ingaphandle kwebhendi yokusebenza ye-BTS.

Isici esiyinhloko

Izici Eziyinhloko
1. Idizayini eyi-duplex egcwele ukuzihlukanisa ephezulu, kulula ukuyifaka.
2. Isibalo somsindo ophansi, ukuzwela okuphezulu.
3. Ngomsebenzi we-ALC kanye ne-MLC ukuze kuqinisekiswe amandla okukhiphayo azinzile.
4. Ukusetshenziswa kwamandla okuphansi, ukuvikelwa kwemvelo nokonga amandla.
5. Isakhiwo se-Modular design, kalula ukuthuthukisa uhlelo.
6. Isihlungi esiphezulu se-Q kanye nesihlungi se-SAW surface acoustic wave, siphezulu ngenxa yokwenqatshwa kwebhendi.
7. Yamukela ukulandelana okuphezulu okuthuthuke kakhulu emhlabeni, isikhulisi samandla se-LDMOS esine-intermodulation ephansi.
8. Yamukela ubuchwepheshe obuthuthukisiwe bedijithali be-PLL, i-TCXO, i-OCXO, ukuzinza kwamafrikhwensi kanye nokunemba okuphezulu.
9. Umsebenzi ophelele wokuqapha inethiwekhi yendawo nendawo.
10. Umsebenzi wokuklama ongangeni manzi waso sonke isimo sezulu esingaphakathi nangaphandle.

Uhlelo lokusebenza&izimo

Izicelo eziphindaphinda imvamisa
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.
