Dongosolo la Kingtone Repeaters lapangidwa kuti lithetse mavuto a siginecha yofooka yam'manja, yomwe ndiyotsika mtengo kwambiri kuposa kuwonjezera Base Station yatsopano (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
- 400Mhz Zofunika Kwambiri◇ Mkulu mzere PA;Kupindula kwakukulu kwadongosolo;
◇ Ukadaulo wanzeru wa ALC;
◇ Full duplex ndi kudzipatula mkulu kuchokera uplink mpaka downlink;
◇ Makinawa Ogwiritsa ntchito bwino;
◇ Njira yophatikizika yokhala ndi magwiridwe antchito odalirika;
◇ Bandwidth imatha kukhazikitsidwa kuchokera ku 5-25MHz mu gulu lantchito.
◇ Kuyang'anira kwanuko komanso patali (posankha) ndi ma alarm angozi & chiwongolero chakutali;
◇ Mapangidwe osagwirizana ndi nyengo pokhazikitsa nyengo zonse;

Mapulogalamu Obwereza
Kukulitsa kufalikira kwa ma siginecha amtundu wakhungu wodzaza pomwe chizindikiro ndi chofooka

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.
