Sisitemu ya Kingtone JIMTOM® Fibre Optic Repeaters yashyizweho kugirango ikemure ibibazo byikimenyetso kigendanwa kidakomeye, kikaba gihenze cyane kuruta gushyiraho Sitasiyo nshya (BTS).Igikorwa nyamukuru cya sisitemu ya RF isubiramo: Kumurongo wamanutse, ibimenyetso biva muri BTS bihabwa Master Unit (MU), MU noneho ihindura ibimenyetso bya RF kuri signal ya laser hanyuma igaburira fibre kugirango yohereze muri Remote Unit (RU).RU noneho ihindure ibimenyetso bya laser kubimenyetso bya RF, hanyuma ukoreshe Power Amplifier kugirango wongere imbaraga nyinshi kuri IBS cyangwa antenne yo gukwirakwiza.Kuri up up ihuza, Nibikorwa bisubira inyuma, ibimenyetso biva kubakoresha mobile bigaburirwa ku cyambu cya MS.Binyuze kuri duplexer, ibimenyetso byongerwaho amajwi make yongerera imbaraga imbaraga kugirango ibimenyetso byongere imbaraga.Noneho ibimenyetso bigaburirwa kuri fibre optique ya RF fibre hanyuma igahinduka mubimenyetso bya laser, hanyuma ibimenyetso bya laser byoherezwa muri MU, ibimenyetso bya laser biva muri RU bihinduka mubimenyetso bya RF na trans optique ya RF optique.Noneho ibimenyetso bya RF byongerewe ibimenyetso byinshi byingufu bihabwa BTS.
RF Repeater yashizweho kugirango izamure imiyoboro ya selile kandi yuzuze ibibanza bihumye.Igikorwa nyamukuru cyisubiramo ni ukwakira ibimenyetso bidafite ingufu biturutse kuri Base Station (BS) binyuze kuri radiyo yumurongo wa radiyo (RF) na antenna yabaterankunga, gutunganya, kongera no kohereza ibimenyetso kuri Sitasiyo ya mobile (MS) mukarere kegeranye na serivisi zayo antenna.
Ibyingenzi
- FPGA Base SDR ikoranabuhanga, Gukarisha inyungu zo kwangwa;
- Imbere kwemeza kugenzura ubwenge, biroroshye kumenya amakosa yo kubungabunga;
- Gukoresha ingufu nke, gukwirakwiza ubushyuhe bwiza;
- Umurongo muremure PA, sisitemu yo hejuru yunguka;
- Gukurikirana hafi na kure (bidashoboka) hamwe no gutabaza byikora & kure;
- Ingano yoroheje, ihindagurika mugushiraho no kwimuka;
- Igishushanyo mbonera cyogushiraho ibihe byose;
- MU imwe irashobora gutwara Max 32 RUs, Kubika ikiguzi no koroshya kwishyiriraho.
- Gushyigikira impeta, urunigi rwa dais, inyenyeri topologiya, kunoza imiyoboro ihindagurika.
- Igishushanyo mbonera-cyinshi, abatwara max 16, Byoroshye gukemura ibintu byinshi byimodoka
