KingTone Tetra DMR UHF 400MHz 450MHz Line Amplifer BDA inoshandiswa Indoor Distributions System (IBS),Basement,Tunnel Coverage.
Indoor Distributions System (IBS),Basement,Tunnel Coverage Solution Matanho:
1. Kuiswa saiti engineering ongororo: Iyo base chiteshi chiratidzo 380-400MHz?
Ko iyo nharembozha inoratidzira panzvimbo yekupinda mukotoni inogamuchira 3-4 masaini (simba remunda rinofanira kunge riine -85dBm kana zvirinani)?Kana zvisina kudaro, tsvaga nzvimbo iri pedyo netunnel ine chiratidzo chakanaka sechiratidzo chekugamuchira chiratidzo;
Ongorora: Nzvimbo yekugamuchira inofanirwa kunge iri chinzvimbo cheiyo antenna yekugamuchira, asi haisi iyo nzvimbo yeanodzokorora.Nharaunda kubva kune antenna yekugamuchira kune inodzokorora haina kuganhurirwa (inogona kuva pedyo kana kure), uye mutengi anozvigadzirisa zvinoenderana neprojekti;
2, kuiswa kweantenna
Anodzokorora achange aine madoko maviri, chiteshi cheBS chakabatana neantenna inogashira (yakananga kubhesi station), uye iyo MS port yakabatana kuvhara antenna (yakananga kunzvimbo yekuvhara);
Nekudaro, kuti udzivise kuzvifadza kweanodzokorora, anodzokorora haakwanise kushanda (kunyanya kuzvidzora kuchaita kuti iyo inodzokorora simba amplifier module kupisa), saka teerera kune maviri anotevera mapoinzi:
a, iyo antenna yekugamuchira uye inovhara antenna inofanira kunge yadzokera kumashure;
b, chinhambwe chiri pakati peantenna yekugamuchira uye inovhara antenna inodarika mamita makumi mashanu, uye nhambwe chaiyo inogadziriswa zvinoenderana nemamiriro chaiwo pane saiti;
c.Kana iyo yekuisa maitiro, chinhambwe pakati peantennas maviri chasvika 80 metres kana kupfuura, hazvibviri kudzivirira wega-excitation.Zvinokurudzirwa kuti vatengi vawedzere mambure ekuzviparadzanisa pakati peantennas maviri (senge chidimbu chikuru chesimbi) kana kushandisa mamiriro enzvimbo kune Iyo antenna yakaparadzaniswa (senge gomo kana chivakwa chikuru);
3, zvinoenderana nenzvimbo yekuvhara: 500 metres tunnel kureba kuisa muchina uri kure
4, feeder & connector: 1/2 ″ coaxial tambo, kureba: vatengi gadzirisa zvinoenderana neprojekiti inoda!
5, kana pane kona mumugero, zvinokurudzirwa kuwedzera maviri-simba splitter kune anodzokorora, kudhonza feeder, uye kuwedzera chivharo antenna kuvhara;
