I-2W TETRA 400mhz iphinda ikhethe ibhendi
Kingtone Repeaters
Inkqubo ye-Kingtone yenzelwe ukusombulula iingxaki zesiginali yeselula ebuthathaka, enexabiso eliphantsi kunokongeza iSikhululo esitsha seSiseko (BTS).Umsebenzi ongundoqo we-RF Repeaters system kukufumana umqondiso wamandla aphantsi osuka 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.

Umnxeba ophindayo
Oku kusetyenziselwa ukwandisa uluhlu lweempawu zefowuni kumgca wefowuni.Zisetyenziswa rhoqo kwii-trunklines ezithwala iifowuni ezikude.Kumgca wefowuni ye-analog equka iperi yeengcingo, iqulethe isiphaluka seamplifier eyenziwe ngee-transistors ezisebenzisa amandla avela kumthombo wangoku we-DC ukunyusa amandla omqondiso we-audio oguqukayo wangoku kumgca.Ekubeni ifowuni iyinkqubo yokunxibelelana (i-bidirectional), isibini socingo sithwala izibonakaliso ezimbini zomsindo, enye ihamba kwicala ngalinye.Ke abaphinda umnxeba kufuneka babe macala omabini, bekhulisa umqondiso kumacala omabini ngaphandle kokubangela impendulo, nto leyo elwenza nzima uyilo lwabo kakhulu.Abaphinda umnxeba babeluhlobo lokuqala lokuphinda kwaye yayizezinye zezicelo zokuqala zokukhulisa.Ukuphuhliswa kweefowuni eziphindaphindayo phakathi kwe-1900 kunye ne-1915 kwenza inkonzo yefowuni yomgama omde yenzeke.Nangona kunjalo uninzi lweentambo zonxibelelwano ngoku ziintambo zefiber optic ezisebenzisa ii-optical repeaters (ngezantsi).

Ukuphindaphinda kweselula
Esi siphindaphindo sikanomathotholo sokunyusa ulwamkelo lweselfowuni kwindawo encinci.Isixhobo sisebenza njengesikhululo esisezantsi seselula, esine-eriyali ekhomba indlela yokufumana umqondiso kwinqaba yeseli ekufutshane, i-amplifier, kunye ne-eriyali yendawo ukuze iphinde isasaze umqondiso kwiiselfowuni ezikufutshane.Ihlala isetyenziswa kwizakhiwo zeeofisi ezisembindini wedolophu.
 

Eyona nto iphambili

Iimpawu eziphambili
◇ Ulandelelwano oluphezulu PA;Ukuzuza kwenkqubo ephezulu
◇ Ubugcisa be-ALC obukrelekrele
◇ I-duplex epheleleyo kunye nokuba yedwa okuphezulu
◇ Ijika elibukhali lokucoca
◇ UkuSebenza okuzenzekelayo ukusebenza ngokufanelekileyo
◇ Uyilo lwemodyuli lula ukulugcina
◇ Ulawulo olukude/ukubeka iliso/i-alamu nge-RF MODEM okanye i-Ethernet
◇ IP65 uyilo lwe-chassis yosetyenziso lwangaphakathi nangaphandle

Isicelo&imeko

Izicelo eziphinda-phinda
Ukwandisa ukugutyungelwa komqondiso wophawu lokuzalisa indawo eyimfama apho umqondiso ubuthathaka
okanye ayifumaneki.
Ngaphandle: Izikhululo zeenqwelomoya, iMimandla yoKhenketho, iiKhosi zeGalufa, iitonela, iifektri, iZithili zeMigodi, iiLali njl.
Ngaphakathi: Iihotele, amaZiko eMiboniso, amagumbi angaphantsi, iivenkile
Iivenkile ezinkulu, iiOfisi, iiNdawo zokuPakisha njl.
Isebenza ikakhulu kwimeko enjalo:
Umntu ophindayo unokufumana indawo yofakelo enokufumana isignali ecocekileyo ye-BTS kwinqanaba elinamandla ngokwaneleyo njengoko iNqanaba le-Rx kwindawo yokuphindaphinda kufuneka ibe ngaphezu kwe- -70dBm;

Kwaye inokuhlangabezana nemfuneko yokuzahlula kwe-antenna ukunqanda ukuzibamba.
