Nidaamyada anteenada la qaybiyey (DAS), sidee hawl-wadeenadu u dooran karaan awood qaybisayaasha iyo lammaaneyaasha ku habboon?

Shabakadaha isgaadhsiinta casriga ah, Nidaamyada Anteenada La Qaybiyay (DAS) waxay noqdeen xal muhiim u ah hawl-wadeenada si ay wax uga qabtaan daboolka gudaha, kobcinta awoodda, iyo gudbinta calaamadaha band-yada badan. Waxqabadka DAS kuma xidhna oo keliya anteenooyinka laftooda, laakiin waxa kale oo si weyn u saameeya qaybo kala duwan oo aan danayn oo ku dhex jira nidaamka, gaar ahaan kuwa kala qaybiya awoodda iyo lammaaneyaasha jihaynta. Doorashada qaybaha saxda ah waxay si toos ah u go'aaminaysaa tayada daboolida calaamada iyo guud ahaan waxtarka hawlgalka shabakada.

I. Doorka Awood Qaybinta DAS

Qaybiyeyaasha awoodda ayaa ugu horreyn loo isticmaalaa in si siman loogu qaybiyo calaamadaha saldhigga saldhigga dekedo anteeno badan oo gudaha ah, taas oo awood u siinaysa daboolida meelo badan.

Tixgelinta Muhiimka ah Marka la dooranayo Qaybiyeyaasha Awoodda:

Gelida Khasaare
Luminta gelinta hoose waxay keentaa waxtarka gudbinta calaamadaha sare. Mashruucyada caymiska gudaha ee baaxadda weyn, hawl-wadeenadu waxay caadiyan door bidaan qaybiyayaal awoodeed oo hooseeya si loo yareeyo khasaaraha korontada.

Go'doominta Dekedda
Go'doominta sare waxay yaraynaysaa wada hadalka dekedaha, iyada oo hubinaysa madax banaanida calaamada anteenooyinka kala duwan.

Awooda Maareynta Awooda
Xaaladaha codsiga awooda sare leh (tusaale, DAS ee goobaha waaweyn), waxaa lama huraan ah in la doorto kala qaybiyayaal awood u leh inay wax ka qabtaan awoodda wax gelinta sare si loo hubiyo hawlgal xasiloon oo muddada dheer ah.

II. Codsiga lammaaneyaasha ee DAS

Lammaanayaasha ayaa loo isticmaalaa in laga soo saaro qayb ka mid ah calaamada jirridda weyn si ay u quudiyaan anteenooyinkooda meelo gaar ah oo gudaha ah, sida marinnada ama qaybinta sagxadda.

Tixgelinta Muhiimka ah Marka la dooranayo Lamaanayaasha:

Qiimaha Isku-xidhka
Qiimaha isku-xiran ee caadiga ah waxaa ka mid ah 6 dB, 10 dB, iyo 15 dB. Qiimaha isku-xidhku wuxuu saameeyaa awoodda loo qoondeeyay anteenooyinka. Hawl-wadeenadu waa inay doortaan qiimaha isku-xidhka ku habboon ee ku salaysan shuruudaha caymiska iyo tirada anteenooyinka.

Jihaynta iyo Go'doominta
Lammaanayaasha jiheynta sare waxay yareeyaan milicsiga calaamadaha, kor u qaadista xasilloonida isku xirka jirridda weyn.

Tilmaamaha PIM hooseeya
Nidaamyada 5G iyo multi-band DAS, lammaaneyaasha is-dhex-galka ah ee dhexdhexaadka ah (PIM) ayaa si gaar ah muhiim u ah si looga fogaado faragelinta dhexdhexaadinta iyo hubinta tayada calaamadaha.

III. Xeeladaha Xulashada Waxtarka leh ee Hawl-wadeenada

Marka la geynayo injineernimada, hawl-wadeennadu waxay caadi ahaan tixgeliyaan arrimaha soo socda si ay si dhammaystiran u doortaan awood-qaybiyayaasha iyo lammaaneyaasha:

Miisaanka Dhacdooyinka Daboolista: Dhismayaasha xafiisyada yaryar waxa laga yaabaa inay adeegsadaan koronto laba-way ama 3-gees ah, halka garoommada waaweyn ama garoonnada diyaaradaha ay u baahan yihiin isku-darka korantada heerar badan ah iyo lammaaneyaal kala duwan.

Taageerada Kooxda-Multi-Band: DAS Casriga ah waa in ay taageertaa inta jeer ee u dhaxaysa 698-2700 MHz iyo xataa fidin ilaa 3800 MHz. Hawl-wadeenadu waxay u baahan yihiin inay doortaan qaybaha dadban ee ku habboon xargaha soo noqnoqda oo buuxa.

Dheelitirnaanta Nidaamka: Iyaga oo si caqli gal ah isu daraya awood qaybiyayaasha iyo lammaaneyaasha, hawl-wadeennadu waxay hubin karaan xoogga signalada dheellitiran ee dhammaan aagagga oo dhan, iyaga oo iska ilaalinaya daboolka indhoolayaasha ama daboolka xad-dhaafka ah.

Chengdu Concept Microwave Technology CO., Ltd waa soo saaraha xirfadeed eeQaybaha mikrowave dadban ee nidaamka DAS, oo ay ku jiraan shaandhada hoose ee RF, filter filter-ka sare, filter filter, filter filter / band stop filter, duplexer, awood qaybiye iyo lammaane jihada. Dhammaantood waxaa lagu habeyn karaa iyadoo loo eegayo shuruudahaaga.
