Ingcaciso yeMveliso

I-TETRA-cable-access MDAS Fiber Optic Repeater isetyenziselwa ukwandisa umqondiso wezixhobo zeTETRA.I-Master Optical Unit System ibamba isignali ye-BTS ye-TETRA kwaye iyiguqule ibe ngumqondiso we-optic kwaye idlulisele isignali ekhulisiwe kwi-Remote Optical Unit nge-fiber optic cables.I-Remote Optical Unit iya kuguqula kwakhona i-optic signal kwi-TETRA isignali kwaye emva koko iguqule i-Downlink Amplifier kwaye inike umqondiso kwiindawo apho ukukhutshwa komsebenzi womnatha kunganelanga.

Kwaye isignali yeselula nayo ikhulisiwe kwaye idluliselwe kwi-BTS ngendlela echaseneyo.Inkqubo yokusasaza yinkampani yethu uphando oluzimeleyo kunye nophuhliso luqulunqwe yi-Master Optical Unit kunye neRemote Optical Unit.Imodyuli yangaphakathi idibaniswe, iteknoloji edibeneyo iphucula ukuzinza kwezixhobo.

 

 

Iimpawu zeMveliso

Inqanaba eliphezulu, ukufumaneka okuphezulu, kulungele ukugcinwa;

Ukwamkela kwangaphakathi iliso elikrelekrele, kulungele ukukhangela iimpazamo ukuze zigcinwe;

Ukusetyenziswa kwamandla aphantsi, ukutshatyalaliswa kobushushu obugqwesileyo;

Umgca ophezulu we-PA, ukuzuza kwenkqubo ephezulu;

Ukubeka iliso kwingingqi nakude;

Ubungakanani obuqinileyo, obuguquguqukayo bofakelo kunye nokufuduswa;

ETSI iyahambelana

 

Eyona nto iphambili

I-400 uhf yekhonkco yekhonkco yefowuni yeselula Iimpawu eziphindayo:

I-1.I-software yokubeka iliso inokuphuculwa kwindawo okanye kude.

2.Uluhlu olubanzi oluguquguqukayo, ukusetyenziswa kwamandla aphantsi kunye nomfanekiso wengxolo.Ukukhuselwa kwi-voltage engaphezulu, ngaphezulu kwangoku kunye nobushushu obungaphezulu

3.Ukuzihlukanisa okuphezulu ukusuka kwi-uplink ukuya kwi-downlink ukuphucula ukuzinza okuphezulu.

I-4.Ukuthembeka okuphezulu kunye ne-MTBF≥100,000 iiyure

5.Umsebenzi ogqibeleleyo wokubeka iliso kwinethiwekhi yendawo ekude kunye nendawo.

6.Kuphephe ukuphazanyiswa kwi-co-frequency

7.Yandisa indawo yokugubungela kunye ne-antenna ye-omni

8Yandisa umgama womqondiso wesikhululo esisisiseko

9.Backup iibhetri

10.Imodyuli engundoqo yokuzivavanya kunye ne-alam ye-auto.

11.I-alamu yokuvula umnyango

12ALC(ulawulo lwenqanaba le-auto), njl.

Isicelo&imeko

I-TETRA 400 REPEATER Izicelo
Ukwandisa ukugutyungelwa komqondiso wophawu lokuzalisa indawo eyimfama apho umqondiso ubuthathaka
okanye ayifumaneki.
Ngaphandle: Izikhululo zeenqwelomoya, iMimandla yoKhenketho, iiKhosi zeGalufa, iitonela, iifektri, iZithili zeMigodi, iiLali njl.
Ngaphakathi: Iihotele, amaZiko eMiboniso, amagumbi angaphantsi, iivenkile
Iivenkile ezinkulu, iiOfisi, iiNdawo zokuPakisha njl.
Isebenza ikakhulu kwimeko enjalo:
Umntu ophindayo unokufumana indawo yofakelo enokufumana isignali ecocekileyo ye-BTS kwinqanaba elinamandla ngokwaneleyo njengoko iNqanaba le-Rx kwindawo yokuphindaphinda kufuneka ibe ngaphezu kwe- -70dBm;

Kwaye inokuhlangabezana nemfuneko yokuzahlula kwe-antenna ukunqanda ukuzibamba.
