Mumasystem eantenna akaparadzirwa (DAS), vashandisi vanogona sei kusarudza ma "power splitters" nema "couplers" akakodzera?

Muma network ekukurukurirana emazuva ano, Distributed Antenna Systems (DAS) yave mhinduro yakakosha kune vanoshanda kugadzirisa kufukidzwa kwemukati, kuwedzerwa kwesimba, uye kutumira masaini akawanda-band. Kushanda kweDAS hakungotsamiri pamaantenna pachawo asi kunokanganiswawo zvakanyanya nezvikamu zvakasiyana-siyana zvisingashande mukati me system, kunyanya ma power splitters nema directional couplers. Kusarudza zvikamu zvakakodzera kunosarudza zvakananga kunaka kwekufukidzwa kwemasaini uye kushanda zvakanaka kwe network.

I. Basa reVaparadziri veMasimba muDAS

Ma "power splitters" anonyanya kushandiswa kuparadzira zviratidzo zve "base station" zvakaenzana kuma "antenna ports" akawanda emukati, zvichiita kuti pave ne "coverage" munzvimbo dzakawanda.

Zvinhu Zvikuru Zvekufunga Pakusarudza Power Splitters:

Kurasikirwa Kwekuisa
Kurasikirwa nekuisa pasi kunoita kuti masaini akwanise kutumirwa zvakanaka. Mumapurojekiti makuru ekuvhara mukati meimba, vanoisa magetsi vanowanzo sarudza ma "spritters" emagetsi asinganyanyi kurasikirwa kuti vaderedze kutambisa magetsi.

Kuparadzaniswa kweChiteshi
Kuparadzaniswa kwakanyanya kunoderedza kutaurirana pakati pemaports, zvichiita kuti zviratidzo zvisashande zvakanaka pakati pemaantenna akasiyana.

Kugona Kubata Simba
Muzviitiko zvekushandisa simba guru (semuenzaniso, DAS munzvimbo dzakakura), zvakakosha kusarudza ma "power splitter" anokwanisa kubata simba repamusoro rekuisa kuti ave nechokwadi chekuti anoshanda kwenguva refu.

II. Kushandiswa kweVanobatanidza muDAS

Makomputa anoshandiswa kuburitsa chikamu chechiratidzo kubva muhunde huru kuti ape maantenna munzvimbo dzakatarwa dzemukati, dzakadai semakoridho kana kugoverwa kwepasi.

Zvinhu Zvikuru Zvekufunga Pakusarudza Vakaroorana:

Kukosha kwekubatanidza
Zvinodiwa pakubatanidza zvinosanganisira 6 dB, 10 dB, uye 15 dB. Kukosha kwekubatanidza kunokanganisa simba rinopihwa kumaantenna. Vashandi vanofanirwa kusarudza kukosha kwakakodzera kwekubatanidza zvichienderana nezvinodiwa pakufukidza uye huwandu hweantenna.

Kutungamira uye Kuzviparadzanisa
Makomputa ane hutungamiriri hwepamusoro anoderedza kuratidzwa kwechiratidzo, zvichiwedzera kugadzikana kwe trunk link huru.

Hunhu hwePIM Yakaderera
Mumasystem e5G nemulti-band DAS, ma "couplers" ePassive Intermodulation (PIM) akakosha zvikuru kudzivirira kupindirana kwe "intermodulation" uye kuona kuti masaini akanaka.

III. Maitiro Ekusarudza Anoshanda Evashandisi

Mukushandiswa kweinjiniya, vashandi vanowanzo funga nezvezvinhu zvinotevera kuti vasarudze zvakakwana ma "power splitters" nema "couplers":

Chiyero Chekufukidza: Zvivako zvidiki zvemahofisi zvinogona kushandisa ma "power splitter" ane nzira mbiri kana nhatu, nepo nhandare huru kana nhandare dzendege dzichida musanganiswa we "multi-stage power splitter" uye ma "coupler" akasiyana-siyana.

Rutsigiro rweMabhendi Akawanda: DAS yemazuva ano inofanira kutsigira huwandu hwemafrequency kubva pa698–2700 MHz uye kunyange kusvika pa3800 MHz. Vashandi vanofanirwa kusarudza zvikamu zvisingashande zvinoenderana nemabhendi efrequency akazara.

Kuenzanisa Kwemasisitimu: Nekubatanidza zvine musoro ma "power splitters" nema "couplers", vashandisi vanogona kuona kuti masaini akaenzana munzvimbo dzese, vachidzivirira nzvimbo dzisingaonekwe kana kuti nzvimbo dzakawandisa.

Chengdu Concept Microwave Technology CO.,Ltd inyanzvi yekugadzira michina yeZvikamu zve microwave zvisingashande yeDAS system, kusanganisira RF lowpass filter, highpass filter, bandpass filter, notch filter/band stop filter, duplexer, Power divider uye directional coupler. Zvese zvinogona kugadziriswa zvichienderana nezvaunoda.
