Kingtone Repeaters
Dongosolo la Kingtone 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.

Wobwereza foni
Izi zimagwiritsidwa ntchito kukulitsa kuchuluka kwa ma siginecha amafoni mumzere wa foni.Amagwiritsidwa ntchito kwambiri m'mizere ya trunklines yomwe imanyamula mafoni akutali.Mu mzere wa telefoni wa analogi wokhala ndi mawaya awiri, imakhala ndi ma amplifier opangidwa ndi ma transistors omwe amagwiritsa ntchito mphamvu kuchokera kugwero lapano la DC kuti awonjezere mphamvu ya siginecha yosinthira pakali pano pamzere.Popeza foni ndi njira yolumikizirana iwiri (bidirectional), mawaya amanyamula ma siginecha awiri, imodzi ikupita mbali iliyonse.Chifukwa chake obwereza mafoni amayenera kukhala apawiri, kukulitsa chizindikiro mbali zonse ziwiri popanda kubweretsa mayankho, zomwe zimasokoneza mapangidwe awo.Obwereza mafoni anali mtundu woyamba wobwereza ndipo anali ena mwazinthu zoyamba zokulitsa.Kukula kwa obwereza matelefoni pakati pa 1900 ndi 1915 kunapangitsa kuti ntchito zamafoni zitheke.Komabe zingwe zambiri zama telecommunications tsopano ndi zingwe za fiber optic zomwe zimagwiritsa ntchito zobwerezabwereza (pansipa).

Mafoni obwereza
Ichi ndi chobwereza chawailesi chothandizira kulandila mafoni am'manja pamalo ochepa.Chipangizocho chimagwira ntchito ngati siteshoni yaing'ono ya ma cellular, yokhala ndi tinyanga yolowera kuti ilandire chizindikiro kuchokera kunsanja yapafupi ya cell, amplifier, ndi mlongoti wakomweko kuti iwonetsenso chizindikirocho kumafoni am'manja apafupi.Nthawi zambiri amagwiritsidwa ntchito m'nyumba zamaofesi amkati.

Ntchito & zochitika

Mapulogalamu Obwereza
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.
