Kingtone 20W Tetra800MHz Two Way Radio UHF Band SelectiveSignal RepeaterDongosolo la Bi-Directional Amplifier lapangidwa kuti lithetse mavuto a siginecha yofooka yam'manja, yomwe ndiyotsika mtengo kwambiri kuposa kuwonjezera Base Station (BTS).Ntchito yayikulu ya RF Repeaters system ndikulandila siginecha yamphamvu yotsika kuchokera ku BTS kudzera pawayilesi yawayilesi ndikutumiza siginecha yokwezeka kumadera omwe kulumikizidwa kwa netiweki sikukwanira.Ndipo siginecha yam'manja imakulitsidwanso ndikutumizidwa ku BTS kudzera mbali ina.
Nkhani yayikulu
- Zofunika Kwambiri za TETRA Repeater:
High linearity PA;Kupindula kwakukulu kwadongosolo;
Intelligent ALC luso;
Duplex wathunthu komanso kudzipatula kwakukulu kuchokera ku uplink kupita ku downlink;
Makinawa Ogwiritsa ntchito bwino;
Integrated njira ndi ntchito odalirika;
Kuyang'anira kwanuko komanso patali (posankha) ndi ma alarm angozi okha & chiwongolero chakutali;
Mapangidwe a Weatherproof pakuyika kwanyengo zonse;
- Ntchito & zochitika

TETRA800Mhz obwereza Mapulogalamu
Kukulitsa kufalikira kwa ma siginecha amtundu wakhungu wodzaza pomwe chizindikiro ndi chofooka
kapena osapezeka.
Panja: Mabwalo a ndege, Madera Oyendera alendo, Maphunziro a Gofu, Tunnel, Mafakitole, Maboma a Migodi, Midzi ndi zina.
M'nyumba: Mahotela, Malo Owonetserako, Zipinda Zapansi, Zogula
Malo ogulitsira, Maofesi, Malo Olongedza, etc.
Zimagwiritsidwa ntchito makamaka pazochitika zotere:
Wobwereza amatha kupeza malo osungira omwe angalandire chizindikiro choyera cha BTS pamlingo wokwanira monga Rx Level mu malo obwereza ayenera kukhala oposa -70dBm;
Ndipo amatha kukwaniritsa kufunikira kwa kudzipatula kwa mlongoti kuti apewe kudzidzidzimutsa.
