Kingtone JIMTOM® Fiber Optic Repeaters system idapangidwa kuti ithetse mavuto a siginecha yofooka yam'manja, yomwe ndiyotsika mtengo kwambiri kuposa kukhazikitsa Base Station (BTS).Kugwira ntchito kwakukulu kwa RF Repeaters system: Pa ulalo wapansi, ma sign ochokera ku BTS amaperekedwa ku Master Unit (MU), MU kenako amasintha chizindikiro cha RF kukhala chizindikiro cha laser kenako amadyetsa ku fiber kuti atumize ku Remote Unit (RU).RU ndiye sinthani chizindikiro cha laser kukhala chizindikiro cha RF, ndikugwiritsa ntchito Power Amplifier kukulitsa mphamvu yayikulu kukhala IBS kapena mlongoti wophimba.Pa ulalo wa mmwamba, Ndi njira yosinthira, ma siginecha ochokera kwa ogwiritsa ntchito amaperekedwa ku doko la MU la MS.Kudzera pa duplexer, siginecha imakulitsidwa ndi amplifier yaphokoso yotsika kuti ipititse patsogolo mphamvu yazizindikiro.Kenako ma sign amadyetsedwa ku RF fiber optical module kenako amasinthidwa kukhala ma laser, ndiye chizindikiro cha laser chimatumizidwa ku MU, chizindikiro cha laser chochokera ku RU chimasinthidwa kukhala chizindikiro cha RF ndi RF Optical transceiver.Kenako ma siginecha a RF amakulitsidwa kuzizindikiro zamphamvu zoperekedwa ku BTS.
RF Repeater idapangidwa kuti ipititse patsogolo kufalikira kwa netiweki yam'manja ndikudzaza malo osawona.Ntchito yayikulu ya obwereza ndikulandila siginecha yamphamvu yotsika kuchokera ku Base Station (BS) kudzera pawailesi yakanema (RF) yoperekedwa ndi mlongoti wopereka, kukonza, kukulitsa ndi kutumiza chizindikirocho ku Mobile Station (MS) pamalo omwe amawunikira ndi ntchito yake. mlongoti.
Main Features
- Tekinoloje ya FPGA Base SDR, Kukulitsa kukanidwa kwa gulu;
- Internal kutengera kuwunika kwanzeru, ndikosavuta kupeza zolakwikazo kuti zisungidwe;
- Kugwiritsa ntchito mphamvu zochepa, kutentha kwabwino kwambiri;
- Mzere wapamwamba PA, kupindula kwakukulu kwadongosolo;
- Kuyang'anira kwanuko komanso patali (posankha) ndi ma alarm angozi okha & chiwongolero chakutali;
- Kukula kocheperako, kusinthika pakukhazikitsa ndi kusamutsa;
- Mapangidwe a Weatherproof pakuyika kwanyengo zonse;
- MU imodzi imatha kuyendetsa Max 32 RUs, Sungani mtengo ndikukhazikitsa mosavuta.
- mphete yothandizira, unyolo wa daisy, topology ya nyenyezi, sinthani kusinthasintha kwa maukonde.
- Mapangidwe onyamula zinthu zambiri, zonyamula 16, Gwiritsani ntchito mosavuta mawonekedwe ogwiritsira ntchito magalimoto ambiri
