Ibisobanuro ku bicuruzwa

TETRA insinga-igera MDAS Fibre Optic Repeater ikoreshwa muguhuza ibimenyetso byibikoresho bya TETRA.Sisitemu ya Optical Unit Sisitemu ifata ibimenyetso bya BTS ya TETRA ikayihindura mubimenyetso bya optique kandi ikohereza ibimenyetso byongerewe imbaraga muri Remote Optical Unit ikoresheje insinga za fibre optique.Igice cya kure cya optique kizahindura ibimenyetso bya optique mubimenyetso bya TETRA hanyuma bihindure Amplifier ya Downlink hanyuma bitange ibimenyetso mubice aho ibikorwa byakazi bidahagije.

Kandi ibimenyetso bigendanwa nabyo byongerewe kandi bisubizwa muri BTS binyuze muburyo bunyuranye.Sisitemu yo gukwirakwiza nisosiyete yacu yigenga ubushakashatsi niterambere bigizwe na Master Optical Unit na Remote Optical Unit.Module y'imbere irahujwe, tekinoroji ihuriweho cyane ni ugutezimbere ibikoresho.

 

 

Ibiranga ibicuruzwa

Urwego rwo hejuru, kuboneka cyane, byoroshye kubungabunga;

Imbere kwemeza kugenzura ubwenge, biroroshye kumenya amakosa yo kubungabunga;

Gukoresha ingufu nke, gukwirakwiza ubushyuhe bwiza;

Umurongo muremure PA, sisitemu yo hejuru yunguka;

Gukurikirana hafi no kure;

Ingano yoroheje, ihindagurika mugushiraho no kwimuka;

Ibyingenzi

400 uhf ibimenyetso bya mobile bihuza gusubiramo Ibiranga:

1.Gukurikirana porogaramu irashobora kuzamurwa mu karere cyangwa kure.

2.Urwego rugari rufite imbaraga, gukoresha ingufu nkeya hamwe n urusaku.Kurinda hejuru ya voltage, hejuru yubushyuhe nubushyuhe

3.Kwitandukanya cyane kuva hejuru kugeza kumanuka kugirango utezimbere.

4.Icyizere kinini hamwe na MTBF≥100.000

5.Gukora neza ibikorwa bya kure kandi byaho bikurikirana.

6. Irinde kwivanga muri co-frequency

7.Gura ahantu ho gukwirakwiza hamwe na anteni ya omni yerekeza

8Kongera intera yerekana ibimenyetso bya sitasiyo fatizo

9.Gusubiza inyuma

10.Icyiciro kinini cyo kwipimisha no gutabaza imodoka.

11.Kingura impuruza

12ALC (kugenzura urwego rwimodoka), nibindi.

TETRA 400 Gusubiramo
Kwagura ibimenyetso byerekana ibimenyetso byuzuye impumyi ahantu ibimenyetso bidakomeye

Mu nzu: Amahoteri, Ibigo byerekana imurikagurisha, Ibasi, Guhaha
Amaduka, Ibiro, Gupakira Byinshi nibindi
Irakoreshwa cyane cyane mururwo rubanza:
Gusubiramo birashobora kubona ahantu hashobora kwakirwa hashobora kwakira ibimenyetso bya BTS kurwego rukomeye bihagije kuko Urwego Rx kurubuga rusubiramo rugomba kurenza d 70dBm;

Kandi irashobora kuzuza ibisabwa byo kwigunga kwa antenne kugirango wirinde kwinyeganyeza.
