Isebenza Kanjani i-Active DAS (Uhlelo Lwe-Antenna Olusabalalisiwe)?

I-“Active DAS” ibhekisela ku-Active Distributed Antenna System. Lobu buchwepheshe buthuthukisa ukumbozwa kwesignali engenantambo kanye nomthamo wenethiwekhi. Nazi ezinye izinto ezibalulekile mayelana ne-Active DAS:

Uhlelo Lwe-Antenna Olusatshalaliswayo (i-DAS): I-DAS ithuthukisa ukumbozwa kwesignali yokuxhumana yeselula kanye nekhwalithi ngokufaka ama-antenna node amaningi ngaphakathi kwezakhiwo noma ezindaweni. Ibhekana nezikhala zokumbozwa ezakhiweni ezinkulu, ezinkundleni zemidlalo, emihubheni yesitimela esingaphansi komhlaba, njll. Ukuze uthole imininingwane eyengeziwe nge-Distributed Antenna Systems (i-DAS),sicela uchofoze lapha.

I-DAS Esebenzayo Yezakhiwo Zezentengiselwano

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

I-Active DAS: Isebenzisa ama-amplifier asebenzayo ukukhulisa amasignali, ihlinzeka ngenzuzo enkulu kanye nobubanzi bokumboza ngesikhathi sokudluliselwa kwamasignali. Lezi zinhlelo zinikeza ukuguquguquka okuphezulu kanye nokuzivumelanisa nezimo, zimboza ngempumelelo izakhiwo ezinkulu noma eziyinkimbinkimbi.

I-Passive DAS: Ayisebenzisi ama-amplifier; ukudluliswa kwesignali kuncike kuma-passive afana nama-feeder, ama-couplers, nama-splitter. I-Passive DAS ifanele izidingo zokumbozwa ezincane kuya kweziphakathi, njengezakhiwo zamahhovisi noma izindawo ezincane zezentengiselwano.

Uhlelo lwe-Active Distributed Antenna System (DAS) luthuthukisa ukumbozwa kwesignali engenantambo kanye nomthamo ngokusebenzisa izingxenye ze-elekthronikhi ezisebenzayo ukukhulisa nokusabalalisa amasignali kulo lonke isakhiwo noma indawo. Nansi indlela esebenza ngayo:

Uhlelo lwe-Antenna Olusatshalaliswayo Olusebenzayo (i-DAS)

Izingxenye

1. Iyunithi Yekhanda:

- Isixhumanisi Sesiteshi Esiyisisekelo: Sixhuma esiteshini esiyisisekelo somhlinzeki wesevisi engenantambo.

- Ukuguqulwa Kwesignali: Kuguqula isignali ye-RF esuka esiteshini esiyisisekelo ibe isignali ye-optical yokudlulisa ngezintambo ze-fiber optic.

Iyunithi Eyinhloko Nekude

2. Izintambo ze-Fiber Optic:

- Dlulisa isignali yokukhanya kusuka kuyunithi yekhanda kuya kumayunithi akude atholakala kuyo yonke indawo embozwe.

Isiphindaphindi se-Fiber Optic (DAS)

3. Amayunithi Akude:

- Ukuguqulwa kwe-Optical kuya ku-RF: Guqula isignali ye-optical ibe yisignali ye-RF.

-Isiphindaphindi se-Fiber Optic: Khulisa amandla esignali ye-RF ukuze imbozwe.

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

4. Ama-antenna:

- Kubekwe ngendlela efanele kulo lonke isakhiwo noma indawo ukuqinisekisa ukusatshalaliswa kwesiginali okufanayo.

I-Antena Yophahla

 Inqubo Yokusebenza

1. Ukwamukelwa Kwesignali:

- Iyunithi ye-head-end ithola isignali ye-RF evela kumhlinzeki wesevisi'isiteshi sesisekelo.

2. Ukuguqulwa Kwesignali Nokudluliswa:

- Isignali ye-RF iguqulwa ibe yisignali yokukhanya futhi idluliselwe ngezintambo ze-fiber optic kumayunithi akude.

3. Ukukhulisa kanye Nokusabalalisa Isignali:

- Amayunithi akude aguqula isignali ye-optical ibe isignali ye-RF, ayikhulise, futhi ayisakaze ngama-antenna axhunyiwe.

4. Ukuxhumana Komsebenzisi:

- Amadivayisi abasebenzisi axhuma kuma-antenna asatshalalisiwe, athola isignali eqinile necacile.

Izinzuzo

- Ukumbozwa Okuthuthukisiwe: Kuhlinzeka ngokumbozwa kwesignali okuqinile nokuqhubekayo ezindaweni lapho imibhoshongo yamaseli yendabuko ingase ingafinyeleli khona ngempumelelo.

- Amandla Athuthukisiwe: Isekela inani elikhulu labasebenzisi namadivayisi ngokusabalalisa umthwalo kuma-antenna amaningi.

- Ukuzivumelanisa nezimo kanye nokusabalala: Kunwetshwa kalula noma kulungiswe kabusha ukuze kuhlangatshezwane nezidingo zokumbozwa ezishintshayo.

- Ukuphazamiseka Okuncishisiwe: Ngokusebenzisa ama-antenna amaningi anamandla aphansi, kunciphisa ukuphazamiseka okuvame ukuhlotshaniswa ne-antenna eyodwa enamandla aphezulu.

Amakesi Okusetshenziswa(Amaphrojekthi kaLintratek)

- Izakhiwo Ezinkulu: Izakhiwo zamahhovisi, izibhedlela, namahhotela lapho izimpawu zeselula ezivela ngaphandle zingase zingangeni khona ngempumelelo.

- Izindawo Zomphakathi: Izinkundla zemidlalo, izikhumulo zezindiza, kanye nezikhungo zemihlangano lapho inani elikhulu labasebenzisi lidinga ukumbozwa kwesignali okuqinile.

- Izindawo Zasemadolobheni: Izindawo zasemadolobheni eziminyene lapho izakhiwo nezinye izakhiwo zingavimba khona izimpawu zeselula zendabuko.

Indawo yokupaka engaphansi komhlaba(I-DAS)

I-Active DAS isebenza ngokusebenzisa inhlanganisela yobuchwepheshe be-optical kanye ne-RF ukukhulisa nokusabalalisa amasignali angenantambo kahle, ihlinzeka ngokumbozwa okuthembekile kanye nomthamo ezindaweni eziyinkimbinkimbi.

Imikhiqizo yokumbozwa kwesignali emkhakheni wezokuxhumana ngeselula: izikhulisi zesignali zefoni ephathekayo, ama-antenna, ama-power splitter, ama-couplers, njll.
