I-Kingtone ibilokhu ithumela izixazululo zokumboza ngaphakathi endlini ngobuchwepheshe obuhlukene kusukela ngo-2011: izingcingo zamaselula (2G, 3G, 4G), UHF, TETRA ... kokubili ujantshi nomgwaqo.
Ubuchwepheshe be-TETRA (Terrestrial Trunked Radio) busetshenziswa emhlabeni wonke
Ezimweni ezithile, ungase udinge amandla esignali engeziwe.Isibonelo, uma abasebenzi bakho besebenza emachwebeni azungezwe ingqalasizinda yezimboni noma bagade indawo engaphansi komhlaba, izinto zokwakha eziwugqinsi (ngokuvamile ukhonkolo noma izindonga zensimbi) zingasebenza njengesithiyo futhi zivimbe isignali.Lokhu cishe kuzobambezela ukuxhumana futhi kwezinye izimo, kuvimbele umsebenzisi ukuthi adlulise futhi athole ulwazi ngokuphelele.
Amanethiwekhi angenantambo athembekile okuphepha komphakathi okuphepha kwesakhiwo adinga ukuzwela okuphezulu kwesamukeli namandla okudlulisela aphezulu e-UHF/TETRA BDA ezindaweni zasemadolobheni eziminyene ngisho nangaphansi komhlaba ukuze ahlangabezane nokumbozwa okukhulu nokusebenza okuthuthukisiwe kwesakhiwo.
Ubuchwepheshe obengeziwe esibunikezayo ukuze siqinisekise ukuxhumana okuthembekile ezindaweni ezinjalo kuhlanganisa abaphindayo ukuze kukhuliswe ububanzi besiginali nge-DAS (Izinhlelo Ze-Antenna Esabalalisiwe).Lokhu kunikeza isixazululo lapho ukuxhumana okubuthakathaka kuyinkinga.Ingatshalwa emabhuloki amafulethi amancane kuya ezakhiweni ezinkulu zokukhiqiza.
Ukuthuthukisa Ukufakwa Kwangaphakathi Esakhiweni · I-Kingtone WIRELESS INIKEZA IZIHLELO ZAMA-ANTENNA EZINGAPHAKATHI EKWAKHIZINI (DAS) KANYE NE-BI-DIRECTIONAL AMPLFIER (BDA)
Ubukhulu besakhiwo bunquma ngempela ukuthi yiluphi uhlobo lwesixazululo ozoba nalo.
Kuzoba i-BDA [i-bidirectional amplifier] yezakhiwo ezincane, kodwa ezakhiweni ezinkulu akusona isixazululo, ngakho-ke udinga ukuhamba ne-fibre-optic DAS.
Ubuchwepheshe obusetshenziswa ekufakweni kwezakhiwo bungasukela ekusakazweni okulula okungaxhunyiwe ku-inthanethi okuletha isignali kusuka ngaphandle kuya ohlelweni lwe-antenna olusabalalisiwe (DAS).
Kuyinethiwekhi ethwebula isignali ye-TETRA ngaphandle kwesakhiwo, iyikhulise futhi iyijove ngaphakathi kubo nge-DAS (isistimu ye-antenna esabalalisiwe) .
