Muri sisitemu za antene zikwirakwizwa (DAS), ni gute abakoresha bashobora guhitamo imashini zikoresha amashanyarazi n'izihuza zikwiye?

Mu miyoboro y'itumanaho igezweho, Sisitemu za Distributed Antenna Systems (DAS) zabaye igisubizo cy'ingenzi ku bakoresha mu gukemura ikibazo cyo gukwirakwira kw'amakuru imbere mu nzu, kongera ubushobozi, no kohereza amajwi menshi. Imikorere ya DAS ntabwo ishingira gusa kuri antene ubwazo ahubwo inagira ingaruka zikomeye ku bice bitandukanye bitagira aho bihurira muri sisitemu, cyane cyane ibice by'amashanyarazi n'ibihuza icyerekezo. Guhitamo ibice bikwiye bigena mu buryo butaziguye ubwiza bw'amajwi n'imikorere myiza y'umuyoboro muri rusange.

I. Uruhare rw'Abatandukanya Ingufu muri DAS

Ibice bigabanya ingufu bikoreshwa cyane cyane mu gukwirakwiza ibimenyetso bya sitasiyo y'ibanze ku byambu byinshi bya antene zo mu nzu, bigatuma habaho ubwikorezi mu bice byinshi.

Ibintu by'ingenzi ugomba kwitaho mu gihe uhitamo amashanyarazi agabanya umuriro:

Igihombo cyo gushyiramo
Gutakaza ingufu nke mu gushyiramo ibintu bituma habaho ubushobozi bwo kohereza amajwi mu buryo bwiza. Mu mishinga minini yo gukwirakwiza umuriro mu nzu, abakoresha bakunze guhitamo gukoresha ibikoresho bigabanya ingufu z'amashanyarazi kugira ngo bagabanye gutakaza ingufu.

Gutandukanya icyambu
Gutandukanya cyane bigabanya uburyo bwo kuvugana hagati y’ibyambu, bigatuma ibimenyetso bitagira aho bibogamira hagati y’antene zitandukanye.

Ubushobozi bwo gucunga ingufu
Mu bihe byo gukoresha ingufu nyinshi (urugero, DAS ahantu hanini), ni ngombwa guhitamo ibikoresho bigabanya ingufu bishobora gukoresha ingufu nyinshi kugira ngo bikomeze gukora neza igihe kirekire.

II. Ikoreshwa ry'abahuza muri DAS

Udukoresho two gukurura ibyuma (couplers) dukoreshwa mu gukuramo igice cy'ikimenyetso mu gice cy'ingenzi cy'imashini kugira ngo dutange antene mu bice byihariye byo mu nzu, nko mu mihanda cyangwa mu bice byo hasi.

Ibintu by'ingenzi ugomba kwitaho mu gihe uhitamo abashakana:

Agaciro ko guhuza
Agaciro gasanzwe ko guhuza karimo 6 dB, 10 dB, na 15 dB. Agaciro ko guhuza kagira ingaruka ku ngufu zihabwa antene. Abakoresha bagomba guhitamo agaciro gakwiye ko guhuza hashingiwe ku bisabwa ku bunini n'umubare wa antene.

Ubuyobozi n'Ishyira mu Kato
Udukoresho two guhuza ibintu dufite icyerekezo cyo hejuru tugabanya urumuri rw'ibimenyetso, bikongera ubusugire bw'umurongo mukuru w'inyuma.

Ibiranga PIM nkeya
Muri sisitemu za 5G na multi-band DAS, ama-coupleur make ya Passive Intermodulation (PIM) ni ingenzi cyane kugira ngo hirindwe kubangamira intermodulation no kwemeza ko ikimenyetso ari cyiza.

III. Ingamba zifatika zo guhitamo abakoresha

Mu gushyiraho ibikoresho by’ikoranabuhanga, abakoresha bakunze gusuzuma ibintu bikurikira kugira ngo bahitemo neza ibikoresho bigabanya ingufu n’ibihuza:

Igipimo cy'uburyo ibintu bikwirakwizwa: Inyubako nto z'ibiro zishobora gukoresha uburyo bwo gutandukanya amashanyarazi bw'impande ebyiri cyangwa eshatu, mu gihe sitade nini cyangwa ibibuga by'indege bisaba uburyo bwo gutandukanya amashanyarazi bw'ibyiciro byinshi n'uburyo butandukanye bwo kuyahuza.

Inkunga y'amabande menshi: DAS igezweho igomba gushyigikira ingano y'amasaha kuva kuri 698–2700 MHz ndetse ikagera no kuri 3800 MHz. Abakoresha bagomba guhitamo ibice bidakora bihuye n'amabande yuzuye.

Ingano ya Sisitemu: Mu guhuza neza ibikoresho bigabanya ingufu n'ibihuza, abakoresha bashobora kwemeza ko ibimenyetso bifite imbaraga zingana mu bice byose, birinda ahantu hatagaragara cyangwa ahantu harenze urugero.

Chengdu Concept Microwave Technology CO., Ltd ni uruganda rw'inzobere mu gukoraIbice bya microwave bidakora kuri sisitemu ya DAS, harimo akayunguruzo ka RF lowpass, akayunguruzo ka highpass, akayunguruzo ka bandpass, akayunguruzo k'urukiramende/agafunguzo ko guhagarika umugozi, akayunguruzo gafata uduce dutatu, agafunguzo gatanga ingufu n'agafunguzo gafata icyerekezo. Byose bishobora guhindurwa hakurikijwe ibyo ukeneye.
