Sharaxaada Alaabta
TETRA cable-helitaanka MDAS Fiber Optic Repeater waxaa loo isticmaalaa in lagu weyneeyo calaamada qalabka TETRA.Nidaamka Unugga Indhaha ee Master-ka wuxuu qabtaa calaamadda BTS ee TETRA wuxuuna u beddelaa signalka indhaha wuxuuna u gudbiyaa signalka la xoojiyay ee Unugga Fog ee Fiber optic.Unugga fogaanta indhaha ayaa dib u rogi doona calaamada aragga ee TETRA ka dibna waxay la sheekaysan doonaan Downlink Amplifier waxayna siin doontaa calaamada meelaha daboolka shaqada saafiga ahi ku filnayn.
Sidoo kale calaamada mobilada ayaa la xoojiyay oo dib loogu gudbiyaa BTS iyada oo loo sii marayo jihada ka soo horjeeda.Nidaamka qaybinta ee shirkaddeena cilmi-baarista madax-bannaan iyo horumarinta waxaa ka kooban Master Unit iyo Unugga Aragga Fog.Qaybta gudaha ayaa isku dhafan, tignoolajiyada aadka isku dhafan ayaa hagaajinaysa xasiloonida qalabka.
Tilmaamaha Alaabta
Heer sare, helitaan sare, ku habboon ilaalinta;
Korjoogteynta garaadka ee gudaha, ayaa ku habboon in la helo cilladaha si loo ilaaliyo;
Isticmaalka tamarta hooseeya, kulaylka aad u fiican;
Khadka sare ee PA, helitaanka nidaamka sare;
la socodka deegaanka iyo fog;
Cabbirka is haysta, u dabacsan rakibida iyo raritaan;
ETSI waafaqi
- Tilmaamaha ugu muhiimsan
-
400 uhf isku xirka signalka mobilada ee soo noqnoqda Astaamaha:
1.Monitoring software waxaa loo cusboonaysiin karaa gudaha ama fog.
2.Wide kala duwan oo firfircoon, isticmaalka tamarta hooseeya iyo sawirka qaylada.Ka ilaalinta koronta ka badan, hadda iyo heerkulka ka sarreeya
3. Go'doomin sare oo ka soo jeeda kor ilaa hoos si loo hagaajiyo xasilloonida sare.
4.High isku halaynta iyo MTBF≥100,000 saacadood
5.Perfect fog iyo shaqada la socodka shabakada degaanka.
6.Ka fogow faragelinta wada-jirnimada
7. Ku balaadhi aagga daboolka anteenada jihada omni
8 Kordhi masaafada signalka saldhiga saldhiga
9.Backup baytariyada
10.Main module is-tijaabi iyo auto alarm.
11.Albaabka digniinta furan

Codsiyada TETRA 400 REPEATER
Si loo balaadhiyo daboolka calaamada buuxinta aagga indha la'aanta ee calaamaduhu daciif yihiin
ama aan la heli karin.
Banaanka: Garoomada Diyaaradaha, Gobolada Dalxiiska, Koorasyada Golf-ka, Tunnel-ka, Warshadaha, Degmooyinka Macdanta, Tuulooyinka iwm.
Gudaha: Hoteelada, Xarumaha Bandhiga, Qaybaha Hoose, Wax iibsiga
Suuqyada, Xafiisyada, Baakadaha Baakadaha iwm.
Inta badan waxay khusaysaa kiiskan:
Soo-celinta waxay heli kartaa meel rakibaadda taasoo heli karta calaamadda BTS saafi ah heer ku filan oo xooggan maadaama heerka Rx ee goobta soo noqnoqda uu ka badan yahay -70dBm;Oo buuxin kara shuruudaha go'doominta anteenada si looga fogaado is-hawlgalayaasha.
