Isebenza njani i-Active DAS (iNkqubo ye-Antenna eSasazwayo)?

“I-Active DAS” ibhekisa kwiNkqubo ye-Active Distributed Antenna. Le teknoloji iphucula ukugqunywa kwesignali engenazingcingo kunye nomthamo wenethiwekhi. Nazi ezinye iingongoma ezibalulekileyo malunga ne-Active DAS:

Inkqubo ye-Antenna eSasazwayo (i-DAS): I-DAS iphucula ukugqunywa kwesignali yonxibelelwano oluphathwayo kunye nomgangatho ngokufaka ii-antenna nodes ezininzi ngaphakathi kwezakhiwo okanye kwiindawo. Ijongana nezikhewu zokugqunywa kwizakhiwo ezinkulu, kumabala emidlalo, kwiitonela zendlela engaphantsi komhlaba, njl. Ukuze ufumane iinkcukacha ezithe vetshe nge-Distributed Antenna Systems (i-DAS),nceda ucofe apha.

I-DAS esebenzayo yeZakhiwo zoRhwebo

1. Umahluko phakathi kwe-Active kunye ne-Passive DAS:

I-Active DAS: Isebenzisa ii-amplifiers ezisebenzayo ukunyusa imiqondiso, ibonelela ngenzuzo enkulu kunye noluhlu lokugubungela ngexesha lokudluliselwa kwesignali. Ezi nkqubo zibonelela ngokuguquguquka okuphezulu kunye nokuguquguquka, zigubungela ngokufanelekileyo izakhiwo ezinkulu okanye ezintsonkothileyo zesakhiwo.

I-Passive DAS: Ayisebenzisi ii-amplifier; ukuhanjiswa kwesignali kuxhomekeke kwii-passive ezifana nee-feeders, ii-couplers, kunye nee-splitters. I-Passive DAS ifanelekile kwiimfuno zokugubungela ezincinci ukuya kweziphakathi, njengezakhiwo zeeofisi okanye iindawo ezincinci zorhwebo.

Inkqubo ye-Active Distributed Antenna System (DAS) iphucula ukugqunywa kwesignali engenazingcingo kunye nomthamo ngokusebenzisa izixhobo ze-elektroniki ezisebenzayo ukukhulisa nokusasaza imiqondiso kuyo yonke isakhiwo okanye indawo. Nantsi indlela esebenza ngayo:

Izinto eziyinxalenye

1. Iyunithi yeNtloko-End:

- Ujongano lweSitishi esiSekelwe kwiBase: Iqhagamshela kwisikhululo esiSekelwe kwiBase somboneleli weenkonzo ezingenazingcingo.

- Ukuguqulwa kweSignali: Iguqula isignali ye-RF esuka kwisikhululo sesiseko ibe sisignali ye-optical yokudlulisela phezu kweentambo ze-fiber optic.

Iyunithi yeNtloko kunye neyokuKhawuleza

2. Iintambo zeFiber Optic:

- Thumela isignali ye-optical ukusuka kwiyunithi yentloko ukuya kwiiyunithi ezikude ezikuyo yonke indawo egubungelayo.

Isiphindi seFiber Optic (DAS)

3. IiYunithi ezikude:

- Ukuguqulwa kwe-Optical ukuya kwi-RF: Guqula isignali ye-optical ibuyele kwisignali ye-RF.

-Isiphindaphindi seFiber Optic: Nyusa amandla esignali ye-RF ukuze igutyungelwe.

- Ii-Antennas: Sabalalisa isignali ye-RF eyandisiweyo kubasebenzisi bokugqibela.

4. Ii-antenna:

- Ibekwe ngobuchule kuyo yonke isakhiwo okanye indawo ukuqinisekisa ukusasazwa kwesignali okufanayo.

 Inkqubo Yokusebenza

1. Ukwamkelwa kweSignali:

- Iyunithi yesiphelo sentloko ifumana isignali ye-RF evela kumboneleli wenkonzo'isikhululo sesiseko.

2. Ukuguqulwa kweSignali kunye nokuThunyelwa kwayo:

- Isignali ye-RF iguqulwa ibe yisignali ye-optical kwaye idluliselwa ngeentambo ze-fiber optic kwiiyunithi ezikude.

3. Ukwandiswa kweSignali kunye noSasazo:

- Iiyunithi ezikude ziguqula isignali ye-optical ibe sisignali ye-RF, ziyikhulise, kwaye ziyisasaze ngee-antenna ezixhunyiweyo.

4. Uqhagamshelo lomsebenzisi:

- Izixhobo zabasebenzisi ziqhagamshela kwi-antenna ezisasaziweyo, zifumana isignali eqinileyo necacileyo.

Iinzuzo

- Ukhuseleko oluphuculweyo: Lubonelela ngokhuseleko oluqinileyo noluqhubekayo kwiindawo apho iinqaba zeseli zemveli zisenokungafikeleli khona ngokufanelekileyo.

- Ubuchule Obuphuculweyo: Ixhasa inani elikhulu labasebenzisi kunye nezixhobo ngokusasaza umthwalo kwii-antenna ezininzi.

- Ukuguquguquka kunye nokukhula: Yandiswa okanye yahlengahlengiswa ngokulula ukuze ihlangabezane neemfuno zogutyungelo ezitshintshayo.

- Ukuphazamiseka Okuncitshisiweyo: Ngokusebenzisa ii-antenna ezininzi ezinamandla aphantsi, kunciphisa ukuphazamiseka okuqhele ukunxulunyaniswa ne-antenna enye enamandla aphezulu.
