Kingtone 20W Tetra800MHz Laba Way Radio UHF Band oo Xul ahCalaamadaha soo noqnoqdaNidaamka Amplifier-ka Bi-Directional waxaa loogu talagalay in lagu xalliyo dhibaatooyinka calaamadaha mobilada ee daciifka ah, kaas oo aad uga jaban in lagu daro Saldhig cusub (BTS).Hawlgalka ugu weyn ee nidaamka RF Repeaters waa in laga helo signalka tamarta yar ee BTS iyada oo loo marayo gudbinta soo noqnoqda raadiyaha ka dibna u gudbiya signalka la xoojiyay meelaha daboolka shabakadu ku filnayn.Iyo calaamada mobilada sidoo kale waa la xoojiyay oo loo gudbiyaa BTS iyada oo loo sii marayo jihada ka soo horjeeda.
Tilmaamaha ugu muhiimsan
- Astaamaha ugu muhiimsan ee ku celcelinta TETRA:
Khadka sare ee PA;Faa'iidada nidaamka sare;
Farsamada ALC ee caqliga leh;
Duplex buuxa iyo go'doon sare laga bilaabo kor ilaa hoos;
Hawlgal toos ah oo ku habboon;
Farsamo isku dhafan oo leh waxqabad la isku halleyn karo;
La socodka deegaanka iyo fogaanta (ikhtiyaarka) oo leh qaylo dhaan toos ah iyo kontorool fog;
Naqshad aan cimilo lahayn oo loogu talagalay rakibaadda hawada oo dhan;

Codsiyada soo noqnoqda ee TETRA800Mhz
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.
