Sisitemu ya Kingtone Repeaters yateguwe kugirango ikemure ibibazo byerekana ibimenyetso bya terefone igendanwa, bihendutse cyane kuruta kongeramo Sitasiyo nshya (BTS).Igikorwa nyamukuru cya sisitemu ya RF isubiramo ni ukwakira ibimenyetso bike byingufu zituruka kuri BTS ukoresheje radiyo yumurongo wa radiyo hanyuma ugahita wohereza ibimenyetso byongerewe imbaraga aho usanga imiyoboro idahagije.Kandi ibimenyetso bigendanwa nabyo byongerewe kandi byoherezwa muri BTS binyuze muburyo bunyuranye.
Ibyingenzi

Ibintu nyamukuru biranga gusubiramo:
1, Umurongo muremure PA;Sisitemu yo hejuru gain
2, Ubuhanga bwubwenge bwa ALC ；
3, Duplex yuzuye hamwe no kwigunga cyane kuva hejuru kugeza kumanuka ；
4, Gukoresha Automatic Igikorwa cyoroshye ；
5, Tekinike ihuriweho hamwe nibikorwa byizewe;
6, Gukurikiranira hafi no kure (bidashoboka) hamwe no gutabaza byikora & kugenzura kure;
7, Igishushanyo mbonera cyogushiraho ibihe byose;
- Porogaramu & Ibihe

GSM 900 mhz ibimenyetso bya terefone Porogaramu
Kwagura ibimenyetso byerekana ibimenyetso byuzuye impumyi ahantu ibimenyetso bidakomeye
cyangwa ntibishoboka.
Hanze: Ibibuga byindege, Uturere twubukerarugendo, Amasomo ya Golf, Imiyoboro, Inganda, Uturere twa Mining, Imidugudu nibindi.
Mu nzu: Amahoteri, Ibigo byerekana imurikagurisha, Ibasi, Guhaha
Amaduka, Ibiro, Gupakira Byinshi nibindi
Irakoreshwa cyane cyane mururwo rubanza:
Gusubiramo birashobora kubona ahantu hashobora kwakirwa hashobora kwakira ibimenyetso bya BTS kurwego rukomeye bihagije kuko Urwego Rx kurubuga rusubiramo rugomba kurenza d 70dBm;
Kandi irashobora kuzuza ibisabwa byo kwigunga kwa antenne kugirango wirinde kwinyeganyeza.
