Isebenza Kanjani I-DAS (Isistimu Ye-Antenna Esatshalalisiwe)?

I-“Active DAS” ibhekisela Kusistimu Ye-Antenna Esabalalisiwe. Lobu buchwepheshe buthuthukisa ukumbozwa kwesignali engenantambo namandla enethiwekhi. Nawa amaphuzu abalulekile mayelana ne-Active DAS:

Isistimu ye-Antenna Esatshalaliswa (i-DAS): I-DAS ithuthukisa ukumbozwa kwesignali yeselula kanye nekhwalithi ngokufaka ama-antenna amaningi ngaphakathi kwezakhiwo noma izindawo. Ibhekana nezikhala zokumboza ezakhiweni ezinkulu, izinkundla, imigudu yesitimela esihamba ngaphansi komhlaba, njll.Ukuze uthole imininingwane eyengeziwe nge-Distributed Antenna Systems (DAS),sicela uchofoze lapha.

I-DAS Esebenzayo Yesakhiwo Sezentengiso

1.Umehluko phakathi kwe-Active ne-Passive DAS:

I-DAS Esebenzayo: Isebenzisa izikhulisamsindo ezisebenzayo ukukhulisa amasignali, ihlinzeka ngenzuzo enkulu nobubanzi bokuhlanganisa phakathi nokudluliswa kwesignali. Lezi zinhlelo zinikeza ukuguquguquka okuphezulu nokuvumelana nezimo, ezimboza ngempumelelo izakhiwo ezinkulu noma eziyinkimbinkimbi.

I-Passive DAS: Ayisebenzisi izikhulisamazwi; ukudluliswa kwesignali kuncike kuzinto zokungenzi lutho ezifana neziphakeli, ama-coupler, nama-splitter. I-Passive DAS ifanele izidingo zekhava ezincane ukuya kosayizi omaphakathi, njengezakhiwo zamahhovisi noma izindawo zokuhweba ezincane.

I-Active Distributed Antenna System (DAS) ithuthukisa ukumbozwa kwesignali engenantambo namandla ngokusebenzisa izingxenye ze-elekthronikhi ezisebenzayo ukukhulisa nokusabalalisa amasignali esakhiweni noma endaweni. Nansi indlela esebenza ngayo:

I-Active Distributed Antenna System (DAS) ithuthukisa ukumbozwa kwesignali engenantambo namandla ngokusebenzisa izingxenye ze-elekthronikhi ezisebenzayo ukukhulisa nokusabalalisa amasignali esakhiweni noma endaweni. Nansi indlela esebenza ngayo:

I-Active Distributed Antenna System (DAS)

Izingxenye

1. Iyunithi Yokuphela Kwekhanda:

- I-Base Station Interface: Ixhuma esiteshini esiyisisekelo somhlinzeki wesevisi ongenazintambo.

- Ukuguqulwa Kwesiginali: Iguqula isignali ye-RF isuka esiteshini esiyisisekelo ibe isignali yokubona ukuze idluliselwe phezu kwezintambo ze-fiber optic.

I-Head-End kanye ne-Remote Unit

2. Izintambo ze-Fiber Optic:

- Dlulisa isignali ye-optical kusuka kuyunithi yokuphela kwekhanda kuya kumayunithi akude atholakala kuyo yonke indawo yokufakwa.

I-Fiber Optic Repeater (DAS)

3. Amayunithi akude:

- I-Optical to RF Conversion: Guqula isignali yokubona ibuyele kusignali ye-RF.

-I-Fiber Optic Repeater: Khulisa amandla esignali ye-RF ukuze uhlanganise.

- Ama-Antenna: Sabalalisa isignali ye-RF ekhulisiwe kubasebenzisi bokugcina.

4. Izimpondo:

- Kubekwe ngendlela efanele esakhiweni sonke noma endaweni ukuze kuqinisekiswe ukusatshalaliswa kwezimpawu ezifanayo.

 Inqubo Yokusebenza

1. Ukwamukela Isiginali:

- Iyunithi yokuphela kwekhanda ithola isignali ye-RF kumhlinzeki wesevisi's base station.

2. Ukuguqulwa Nokudluliswa Kwesiginali:

- Isignali ye-RF iguqulwa ibe isignali yokubona futhi idluliselwe ngezintambo ze-fiber optic kumayunithi akude.

3. Ukukhulisa Isignali Nokusabalalisa:

- Amayunithi akude aguqula isignali yokubona ibuyele kusignali ye-RF, ikhulise, futhi isabalalise ngezinti ezixhunyiwe.

4. Ukuxhumana komsebenzisi:

- Imishini yabasebenzisi ixhumeka kuzinti ezisabalalisiwe, ithola isignali eqinile necacile.

Izinzuzo

- Ukufakwa Okuthuthukisiwe: Inikeza ukumbozwa kwesiginali okungaguquki futhi okuqinile ezindaweni lapho imibhoshongo yamaseli evamile ingase ingafinyeleli kahle.

- Amandla Athuthukisiwe: Isekela inombolo ephezulu yabasebenzisi namadivayisi ngokusabalalisa umthwalo kuwo wonke ama-antenna.

- Ukuvumelana nezimo nokuqina: Kunwetshwa kalula noma kulungiselelwe kabusha ukuze kuhlangatshezwane nezidingo ezishintshayo zokuhlanganisa.

- Ukuphazamisa Okuncishisiwe: Ngokusebenzisa izimpondo eziningi ezinamandla amancane, kunciphisa ukuphazamiseka okuvame ukuhlotshaniswa ne-antenna eyodwa enamandla amakhulu.

Sebenzisa Amacala(Amaphrojekthi we-Lintratek)

- Izakhiwo Ezinkulu: Izakhiwo zamahhovisi, izibhedlela, namahhotela lapho amasignali eselula avela ngaphandle engase angangeni kahle.

- Izindawo Zomphakathi: Izinkundla zemidlalo, izikhumulo zezindiza, nezikhungo zemihlangano lapho ukuminyana okuphezulu kwabasebenzisi kudinga ukumbozwa kwesignali okuqinile.

- Izindawo zasemadolobheni: Izindawo zasemadolobheni eziminyene lapho izakhiwo nezinye izakhiwo zingavimba amasignali amaselula endabuko.

Indawo Yokupaka Engaphansi(DAS)

I-Active DAS isebenza ngokusebenzisa inhlanganisela yobuchwepheshe be-optical kanye ne-RF ukuze ikhulise futhi isabalalise amasignali angenantambo kahle, inikeze ukumbozwa okuthembekile namandla ezindaweni eziyinkimbinkimbi.

Lintratek Indlunkulu

I-Lintratekube ngumkhiqizi ochwepheshe we-DAS (Isistimu ye-Antenna esabalalisiwe) ngemishini ehlanganisa i-R&D, ukukhiqiza, nokudayiswa iminyaka eyi-12. Imikhiqizo yokumboza isignali emkhakheni wezokuxhumana ngomakhalekhukhwini: izithuthukisi zesiginali yeselula, izinti, izihlukanisi zamandla, ama-couplers, njll.
