"I-DAS esebenzayo" ibhekisa kwiNkqubo ye-Antenna eSasazo eSebenzayo. Le teknoloji iphakamisa ukugubungela umqondiso we-wireless kunye nomthamo wenethiwekhi. Nanga amanye amanqaku aphambili malunga ne-DAS esebenzayo:
Inkqubo ye-Antenna esasazwayo (DAS): I-DAS iphucula ukubethelwa komqondiso wonxibelelwano lweselula kunye nomgangatho ngokufaka ii-antenna ezininzi ngaphakathi kwezakhiwo okanye kwiindawo. Ijongana nezithuba zokugqunywa kwizakhiwo ezikhulu, amabala emidlalo, iitonela zendlela engaphantsi komhlaba, njl.nceda ucofe apha.
I-DAS esebenzayo yeZakhiwo zoRhwebo
1.Umahluko phakathi kwe-DAS eSebenzayo kunye nePassive:
I-DAS esebenzayo: Isebenzisa i-amplifiers esebenzayo ukunyusa imiqondiso, inika inzuzo enkulu kunye noluhlu lokugubungela ngexesha lokuhanjiswa kwesignali. Ezi nkqubo zibonelela ngokuguquguquka okuphezulu kunye nokuguquguquka, ukugubungela ngokufanelekileyo izakhiwo ezinkulu okanye ezinzima zokwakha.
I-Passive DAS: Ayisebenzisi izandisi; Ugqithiso lwesignali luxhomekeke kwizinto zokwenziwa ezinje ngezondla, ii-couplers, kunye neziqhekezayo. I-Passive DAS ilungele iimfuno ezincinci ukuya kweziphakathi, njengezakhiwo zeofisi okanye iindawo ezincinci zorhwebo.
INkqubo ye-Antenna eSasazo eSebenzayo (DAS) yongeza ukugutyungelwa kophawu olungenazingcingo kunye nomthamo ngokusebenzisa izixhobo ze-elektroniki ezisebenzayo ukukhulisa nokusasaza imiqondiso kwisakhiwo sonke okanye kwindawo. Nantsi indlela esebenza ngayo:

Inkqubo yeAntenna esebenzayo (DAS)
Amacandelo
1. ICandelo leNtloko:
-Base Station Interface: Iqhagamshela kwisikhululo esisisiseko somboneleli wenkonzo.
- Uguqulo loMqondiso: Ukuguqula isignali yeRF ukusuka kwisikhululo esisisiseko ukuya kwisignali yokubona yokusasazwa ngeentambo zefiber optic.
INtloko-Isiphelo kunye neYunithi ekude
2. Iintambo zeFiber Optic:
- Dlulisa umqondiso we-optical ukusuka kwiyunithi yokuphela kwentloko ukuya kwiiyunithi ezikude ezikuyo yonke indawo yokugubungela.
IFiber Optic Repeater (DAS)
3. IiYunithi ezikude:
-I-Optical to RF Conversion: Guqula isignali yokukhanya kwakhona ibe ngumqondiso weRF.
-IFiber Optic Repeater: Nyusa amandla omqondiso weRF ukuze ufikelele.
- Ii-eriyali: Ukuhambisa isignali yeRF eyandisiweyo kubasebenzisi bokugqibela.
4. Iimpondo:
- Ibekwe ngobuchule kwisakhiwo sonke okanye indawo ukuqinisekisa ukuhanjiswa kweempawu ezifanayo.
Inkqubo yokusebenza
1. Ulwamkelo loMqondiso:
- Iyunithi yokuphela kwentloko ifumana isignali yeRF kumboneleli wenkonzo's isiseko sesikhululo.
2. Uguqulo loMqondiso kunye noThutho:
- Isiginali yeRF iguqulwa ibe ngumqondiso wokukhanya kwaye idluliselwe ngeentambo zefiber optic kwiiyunithi ezikude.
3. Ukwandiswa koMqondiso kunye noSasazo:
-Iiyunithi ezikude ziguqula umqondiso wokukhanya ubuyele kumqondiso weRF, uyandise, kwaye usasazwe ngee-eriyali eziqhagamshelweyo.
4. UQhagamshelwano lomsebenzisi:
- Izixhobo zabasebenzisi zidibanisa kwii-antenna ezisasazwayo, zifumana isignali eqinile kwaye ecacileyo.
Iingenelo
- Ugutyulo oluPhuculweyo: Ibonelela ngophawu olungaguquguqukiyo noluqinileyo kwiindawo apho iinqaba zeseli zemveli zinokungafikeleli ngokufanelekileyo.
-Umthamo ophuculweyo: Ixhasa inani eliphezulu labasebenzisi kunye nezixhobo ngokusabalalisa umthwalo kwii-antenna ezininzi.
-Ukubhetyebhetye kunye nokuScalability: Ukwandiswa ngokulula okanye uhlengahlengiso ukuze kuhlangatyezwane neemfuno zoguqulo.
- Ukunciphisa Ukuphazamiseka: Ngokusebenzisa ii-eriyali ezininzi zamandla aphantsi, kunciphisa ukuphazamiseka okuqhelekileyo okuhambelana ne-eriyali eyodwa ephezulu.
Sebenzisa Amatyala(Iiprojekthi zeLintratek)
- Izakhiwo Ezikhulu: Izakhiwo zeeofisi, izibhedlele kunye neehotele apho iisignali zeselula ezisuka ngaphandle zisenokungangeni kakuhle.
-IiNdawo zikaWonke-wonke: Amabala emidlalo, izikhululo zeenqwelo moya, kunye namaziko endibano apho uxinaniso oluphezulu lwabasebenzisi lufuna umboniso owomeleleyo.
