Incazelo Yomkhiqizo
I-TETRA yokufinyelela ikhebula ye-MDAS Fiber Optic Repeater isetshenziselwa ukukhulisa isignali yemishini ye-TETRA.I-Master Optical Unit System ithwebula isignali ye-BTS ye-TETRA futhi iyiguqule ibe isignali ye-optic futhi idlulisele isignali ekhulisiwe ku-Remote Optical Unit ngezintambo ze-fiber optic.I-Remote Optical Unit izoguqula isignali ye-optic ibe isignali ye-TETRA bese iguqulela i-Downlink Amplifier futhi inikeze isignali ezindaweni lapho ukumbozwa kwenetha komsebenzi kunganele.
Futhi isignali yeselula nayo iyakhuliswa futhi idluliselwe ku-BTS ngendlela ehlukile.Uhlelo lokusabalalisa olwenziwa yinkampani yethu ucwaningo oluzimele kanye nentuthuko lwakhiwe yi-Master Optical Unit kanye ne-Remote Optical Unit.Imojula yangaphakathi ihlanganisiwe, ubuchwepheshe obudidiyelwe kakhulu buthuthukisa ukuzinza kwemishini.
Izici Zomkhiqizo
Izinga eliphezulu, ukutholakala okuphezulu, okulula ukugcinwa;
Ukuqapha kwangaphakathi okuhlakaniphile, kulula ukuthola amaphutha ukuze kugcinwe;
Ukusetshenziswa kwamandla okuphansi, ukuchithwa kokushisa okuhle kakhulu;
I-PA ephezulu yomugqa, inzuzo ephezulu yesistimu;
Ukuqapha kwendawo kanye nokude;
Usayizi ohlangene, oguquguqukayo ukuze ufakwe futhi uthuthwe;
I-ETSI iyahambisana

I-400 uhf yesixhumanisi sokuphinda isixhumanisi sesiginali yeselula Izici:
Isofthiwe ye-1.Monitoring ingathuthukiswa endaweni noma ukude.
2.Ibanga elinamandla elibanzi, ukusetshenziswa kwamandla okuphansi kanye nesibalo somsindo.Ukuvikelwa ku-voltage engaphezu kwamandla, phezu kwezinga lokushisa lamanje nangaphezulu
3.Ukuhlukaniswa okuphezulu kusuka phezulu kuya phansi ukuze kuthuthukiswe ukuzinza okuphezulu.
4.Ukuthembeka okuphezulu kanye ne-MTBF≥100,000 amahora
5.Umsebenzi ophelele wokuqapha inethiwekhi yendawo nendawo.
6.Gwema ukuphazanyiswa yi-co-frequency
7.Khulisa indawo yokumboza nge-omni directional antenna
8Nweba ibanga lesiginali lesiteshi esiyisisekelo
9.Amabhethri ekhophi yasenqolobaneni
10.Main module ukuzihlolela kanye auto alarm.

Izicelo ze-TETRA 400 REPEATER
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.
