I-China Kingtone inikezela ngexabiso eliSebenzayo loKhuseleko loLuntu lwe-TETRA, i-IDEN 800 MHz i-Band Frequency 806-821/851-866 MHz ephindaphinda i-BDA Bi-Directional Amplifier yoNxibelelwano oluBalulekileyo.
Inkqubo ye-TETRA 800MHz +33dBm Off-air Bi-Directional Amplifier(BDA) yenzelwe ukusombulula iingxaki zesiginali yeselula ebuthathaka, enexabiso eliphantsi kunokongeza iSikhululo esitsha seSiseko (BTS).Umsebenzi ongundoqo we-RF Repeaters system kukufumana umqondiso wamandla aphantsi ovela kwi-BTS ngosasazo lwamaza kanomathotholo emva koko usasaze umqondiso owandisiweyo kwiindawo apho unxibelelwano lwenethiwekhi lunganelanga.Kwaye isiginali yeselula nayo ikhulisiwe kwaye idluliselwe kwi-BTS ngendlela echaseneyo.
Engundoqo Iimbonakalo
◇ Ulandelelwano oluphezulu PA;Ukuzuza kwenkqubo ephezulu;
◇ Ubuchwephesha be-ALC obukrelekrele;
◇ I-duplex epheleleyo kunye nokwahlukaniswa okuphezulu ukusuka kwi-uplink ukuya kwi-downlink;
◇ Ukusebenza okuzenzekelayo ukusebenza kakuhle;
◇ Ubuchule obudityanisiweyo kunye nokusebenza okuthembekileyo;
◇ Ujongo lwasekhaya kunye nolukude (ukhetho) nge-alam yempazamo ezenzekelayo & nolawulo olukude;
◇ uyilo lokumelana nemozulu kufakelo lwemozulu yonke;
Usetyenziso oluqhelekileyo:
Kulwakhiwo lwangaphakathi ukhuseleko lukawonke-wonke uthungelwano olungenazingcingo olubanzi iDEN Isiphindaphindi 800MHz (806-821MHz / 851-866MHz ) Isandisi esiPhindayo se-BDA
ukwandisa ukugubungela umqondiso weendawo ezingaboniyo apho umqondiso ubuthathaka okanye ungafumanekiyo.
1. Ukhuselo lwesakhiwo esincinci sangaphakathi
2. Ukhuselo lwesakhiwo esiphakamileyo
3. Ukugquma kwetonela
4. Indlela ehamba phantsi komhlaba
5. Ukhuseleko lwemoto
6.igumbi elingaphantsi komhlaba
