I-KingTone Tetra DMR UHF 400MHz 450MHz i-Amplifaya ye-BDA esetyenziselwa i-Indoor Distributions System (IBS), iBasement, iTunnel Coverage

Inkqubo yoSabelo lwangaphakathi (IBS), iBasement, iTunnel Coverage Solution amanyathelo:

1. Ufakelo lwesaveyi yobunjineli bendawo: Ngaba isignali yesikhululo sesiseko 380-400MHz?

Ngaba umqondiso weselfowuni kwindawo yokungena kwitonela ufumana iimpawu ze-3-4 (amandla entsimi kufuneka ubuncinane abe -85dBm okanye ngcono)?Ukuba akunjalo, khangela indawo ekufutshane netonela enophawu oluhle njengendawo yokwamkela umqondiso;

Qaphela: Indawo yokufumana kufuneka ibe yindawo yokufumana i-eriyali, kodwa akusiyo indawo yophindaphinda.Umgama ukusuka kwi-antenna efumanayo ukuya kwi-repeater ayikhawulelwanga (inokuba kufuphi okanye ikude), kwaye umthengi uyazilungisa ngokweprojekthi;

2, ufakelo lwe-eriyali

Ukuphindaphinda kuya kuba namachweba amabini, i-port ye-BS ixhunyiwe kwi-antenna yokufumana (ukuya kwisikhululo sesiseko), kunye ne-MS port ixhunyiwe ukugubungela i-antenna (ebhekiselele kwindawo yokugubungela);

Nangona kunjalo, ukuze uthintele ukuzivuselela komntu ophindayo, umntu ophindayo akakwazi ukusebenza (ukuzivuselela kakhulu kuya kubangela ukuba imodyuli yokukhulisa amandla ephindaphindayo iphele), ke nikela ingqalelo kula manqaku mabini alandelayo:

a, i-eriyali eyamkelayo kunye ne-eriyali yokugquma kufuneka zibuyele ngasemva;

b, umgama phakathi kwe-eriyali efumanayo kunye ne-eriyali yokugubungela ubuncinci ngaphezu kweemitha ezingama-50, kwaye umgama othile ulungelelaniswe ngokwemeko yangempela kwisiza;

c.Ukuba inkqubo yokufakela, umgama phakathi kwee-antenna ezimbini ufikelele kwiimitha ezingama-80 okanye ngaphezulu, akunakwenzeka ukuphepha ukuzikhupha.Kucetyiswa ukuba abathengi bongeze umnatha wokuzihlukanisa phakathi kwee-eriyali ezimbini (ezifana nentsimbi enkulu) okanye basebenzise iimeko zesayithi ukuya I-eriyali yodwa (njengentaba okanye isakhiwo esikhulu);

3, ngokwendawo yokhuselo: ubude betonela yeemitha ezingama-500 ukubeka umatshini okude

I-4, i-feeder kunye nesixhumi: 1/2 "intambo ye-coaxial, ubude: abathengi benza ngokweemfuno zeprojekthi!

I-5, ukuba kukho ikona kwi-tunnel, kucetyiswa ukuba ungeze i-splitter yamandla amabini kwi-repeater, ukutsala i-feeder, kwaye ungeze i-antenna yokugubungela;
