Kodi Active DAS (Distributed Antenna System) Imagwira Ntchito Bwanji?

"Active DAS" ikutanthauza Active Distributed Antenna System. Ukadaulo uwu umathandizira kufalikira kwa ma siginolo opanda zingwe komanso mphamvu ya netiweki. Nazi mfundo zazikulu zokhudza Active DAS:

Dongosolo la Ma Antena Ogawidwa (DAS): DAS imakulitsa kufalikira kwa zizindikiro zolumikizirana pafoni komanso ubwino wake mwa kugwiritsa ntchito ma antenna node angapo mkati mwa nyumba kapena madera. Imathetsa mipata yofalikira m'nyumba zazikulu, mabwalo amasewera, ngalande zapansi panthaka, ndi zina zotero. Kuti mudziwe zambiri za Ma Distributed Antenna Systems (DAS),chonde dinani apa.

DAS Yogwira Ntchito Yomanga Malonda

1. Kusiyana pakati pa Active ndi Passive DAS:

Active DAS: Imagwiritsa ntchito ma amplifiers olimbikitsira ma siginecha, kupereka phindu lalikulu komanso kufalikira kwakukulu panthawi yotumiza ma siginecha. Machitidwewa amapereka kusinthasintha kwakukulu komanso kusinthasintha, zomwe zimathandiza kwambiri kumanga nyumba zazikulu kapena zovuta.

Passive DAS: Sigwiritsa ntchito ma amplifiers; kutumiza ma signal kumadalira ma passive monga ma feeder, ma couplers, ndi ma splitters. Passive DAS ndi yoyenera pa zosowa zazing'ono mpaka zapakati, monga nyumba zamaofesi kapena malo ang'onoang'ono amalonda.

Dongosolo Logawanitsa Ma Antenna Logwira Ntchito (DAS) limathandizira kufalikira kwa ma siginolo opanda zingwe komanso mphamvu pogwiritsa ntchito zida zamagetsi zogwira ntchito kuti zikulitse ndikugawa ma siginolo m'nyumba kapena m'dera lonselo. Umu ndi momwe imagwirira ntchito:

Zigawo

1. Chigawo Chothandizira Kugwira Ntchito:

- Chiyanjano cha Siteshoni Yoyambira: Chimalumikizana ndi siteshoni yoyambira ya wopereka chithandizo cha opanda zingwe.

- Kusintha kwa Chizindikiro: Kumasintha chizindikiro cha RF kuchokera ku siteshoni yoyambira kukhala chizindikiro cha kuwala chotumizira kudzera pa zingwe za fiber optic.

Chipinda Chokhala ndi Mutu ndi Chigawo Chotalikirana

2. Zingwe za Fiber Optic:

- Tumizani chizindikiro cha kuwala kuchokera ku gawo lakutsogolo kupita ku mayunitsi akutali omwe ali kudera lonse lophimba.

3. Mayunitsi akutali:

- Kusintha kwa kuwala kukhala RF: Sinthani chizindikiro cha kuwala kukhala chizindikiro cha RF.

-Chobwerezabwereza cha CHIKWANGWANI CHA CHIKWANGWANI: Wonjezerani mphamvu ya chizindikiro cha RF kuti chikhale chotetezeka.

- Ma Antena: Gawani chizindikiro cha RF chokwezedwa kwa ogwiritsa ntchito.

4. Ma antenna:

- Imayikidwa mwanzeru m'nyumba yonse kapena m'dera lonselo kuti zitsimikizire kuti zizindikiro zikufalikira mofanana.

 Njira Yogwirira Ntchito

1. Kulandira Zizindikiro:

- Chipangizo cholumikizira mutu chimalandira chizindikiro cha RF kuchokera kwa wopereka chithandizo'siteshoni ya maziko.

2. Kusintha ndi Kutumiza kwa Chizindikiro:

- Chizindikiro cha RF chimasanduka chizindikiro cha kuwala ndipo chimatumizidwa kudzera mu zingwe za fiber optic kupita ku mayunitsi akutali.

3. Kukulitsa ndi Kugawa Zizindikiro:

- Mayunitsi akutali amasintha chizindikiro cha kuwala kukhala chizindikiro cha RF, kuchikulitsa, ndikuchigawa kudzera mu ma antenna olumikizidwa.

4. Kulumikizana kwa Ogwiritsa Ntchito:

- Zipangizo za ogwiritsa ntchito zimalumikizana ndi ma antenna omwe amagawidwa, ndikulandira chizindikiro champhamvu komanso chomveka bwino.

Ubwino

- Kuphimba Kwabwino: Kumapereka chithandizo chokhazikika komanso champhamvu cha ma signali m'malo omwe nsanja zachikhalidwe za cell sizingafikire bwino.

- Kuthekera Kowonjezereka: Kumathandizira ogwiritsa ntchito ambiri ndi zida pogawa katunduyo m'ma antenna angapo.

- Kusinthasintha ndi Kukula: Kumakulitsidwa mosavuta kapena kukonzedwanso kuti kukwaniritse zosowa zosintha za chithandizo.

- Kuchepetsa Kusokoneza: Pogwiritsa ntchito ma antenna angapo amphamvu zochepa, zimachepetsa kusokoneza komwe kumachitika nthawi zambiri ndi antenna imodzi yamphamvu kwambiri.

Makesi Ogwiritsira Ntchito(Mapulojekiti a Lintratek)

- Nyumba Zazikulu: Nyumba za maofesi, zipatala, ndi mahotela kumene zizindikiro za mafoni ochokera kunja sizingalowe bwino.

- Malo Opezeka Anthu Onse: Mabwalo amasewera, ma eyapoti, ndi malo ochitira misonkhano komwe anthu ambiri amafunikira kulumikizidwa bwino ndi zizindikiro.

- Madera a Mizinda: Malo okhala ndi anthu ambiri m'mizinda komwe nyumba ndi zinthu zina zingatseke ma signal achikhalidwe a ma cell.

Active DAS imagwira ntchito pogwiritsa ntchito ukadaulo wa kuwala ndi RF kuti iwonjezere ndikugawa ma siginecha opanda zingwe bwino, kupereka kufalikira kodalirika komanso mphamvu m'malo ovuta.

Ofesi Yaikulu ya Lintratek

Lintratekwakhala katswiri wopanga DAS (Dongosolo la Antena Logawidwa) ndi zida zomwe zikuphatikiza kafukufuku ndi chitukuko, kupanga, ndi kugulitsa kwa zaka 12. Zinthu zokhudzana ndi zizindikiro m'munda wa kulumikizana kwa mafoni: zolimbikitsira zizindikiro za mafoni, ma antenna, ma power splitters, ma couplers, ndi zina zotero.
