Muri sisitemu ya antenne yagabanijwe (DAS), nigute abashoramari bashobora guhitamo amashanyarazi akwiranye?

Mumuyoboro wogutumanaho ugezweho, Sisitemu Antenna Yagabanijwe (DAS) yabaye igisubizo gikomeye kubakoresha kugirango bakemure ubwikorezi bwo murugo, kongera ubushobozi, no kohereza ibimenyetso byinshi. Imikorere ya DAS ntabwo iterwa na antenne yonyine ahubwo inaterwa cyane nibintu bitandukanye byinjira muri sisitemu, cyane cyane ibice byamashanyarazi hamwe nabahuza icyerekezo. Guhitamo ibice bikwiye byerekana neza ubwiza bwikimenyetso hamwe nibikorwa rusange byurusobe.

I. Uruhare rwamashanyarazi muri DAS

Amashanyarazi akoreshwa cyane cyane mugukwirakwiza kuringaniza ibimenyetso bya sitasiyo ya porte ya antenne yo mu nzu, ituma ikwirakwizwa ahantu henshi.

Ibyingenzi Byingenzi Mugihe Uhitamo Imbaraga Zitandukanya:

Gutakaza
Igihombo cyo hasi gitera ibisubizo byoherejwe neza. Mu mishinga minini yo gukwirakwiza mu ngo, abashoramari bahitamo kugabanya amashanyarazi make kugirango bagabanye gutakaza ingufu.

Kwigunga
Kwigunga cyane kugabanya inzira hagati yicyambu, byemeza ubwigenge bwibimenyetso muri antene zitandukanye.

Ubushobozi bwo Gukoresha Imbaraga
Muburyo bukomeye bwo gukoresha ibintu (urugero, DAS ahantu hanini), ni ngombwa guhitamo amashanyarazi ashoboye gukoresha imbaraga zinjiza nyinshi kugirango ibikorwa byigihe kirekire bihamye.

II. Porogaramu y'Abashakanye muri DAS

Abashakanye bakoreshwa mugukuramo igice cyikimenyetso kumurongo munini kugirango bagaburire antene mubice byihariye byo murugo, nka koridoro cyangwa kugabana hasi.

Ibitekerezo byingenzi muguhitamo abashakanye:

Agaciro
Indangagaciro zisanzwe zirimo 6 dB, 10 dB, na 15 dB. Agaciro ko guhuza kagira imbaraga zahawe antene. Abakoresha bagomba guhitamo agaciro gakwiye gashingiye kubisabwa hamwe numubare wa antene.

Ubuyobozi no kwigunga
Ihuza-rinini cyane rigabanya ibimenyetso byerekana ibimenyetso, byongera ituze ryibihuza nyamukuru.

Ibiranga PIM Ntoya
Muri sisitemu ya 5G hamwe na bande nyinshi ya DAS, abahuza buke ba Passive Intermodulation (PIM) ni ngombwa cyane kugirango birinde kwivanga kwa intermodulation no kwemeza ubuziranenge bwibimenyetso.

III. Ingamba zifatika zo guhitamo kubakoresha

Mubikorwa bya injeniyeri, abashoramari basuzuma ibintu bikurikira kugirango bahitemo byimazeyo amashanyarazi hamwe na coupers:

Igipimo cya Coverage Scenario Igipimo: Inyubako ntoya y'ibiro irashobora gukoresha ibice 2 cyangwa 3 bigabanya amashanyarazi, mugihe stade nini cyangwa ibibuga byindege bisaba guhuza ibice byinshi byamashanyarazi hamwe na coupers zitandukanye.

Inkunga ya Multi-Band: DAS igezweho igomba gushyigikira inshuro zingana kuva 698-22700 MHz ndetse ikagera no kuri 3800 MHz. Abakoresha bakeneye guhitamo ibice bya pasiporo bihujwe na bande yuzuye.

Impirimbanyi ya sisitemu: Muguhuza gushyira mu gaciro amashanyarazi hamwe na coupers, abashoramari barashobora kwemeza imbaraga zerekana ibimenyetso byuzuye mubice byose, bakirinda gukwirakwiza ahantu hatabona cyangwa kurenza urugero.

Chengdu Concept Microwave Technology CO., Ltd numushinga wabigize umwuga waIbikoresho bya microwave byoroshye Sisitemu ya DAS, harimo akayunguruzo ka RF, akayunguruzo, akayunguruzo, akayunguruzo, akayunguruzo / umurongo uhagarika akayunguruzo, duplexer, Imbaraga igabanya icyerekezo hamwe. Byose birashobora gutegurwa ukurikije requrements yawe.
