Isebenza Njani I-DAS (iNkqubo ye-Antenna eSasazo)?

"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 (i-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.

I-Antenna yesilingi

 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 zeeseli 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, 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.
