"Active DAS" zvinoreva Active Distributed Antenna System. Iyi tekinoroji inowedzera kuvharwa kwemasaini asina waya uye kugona kwenetwork. Heano mamwe mapoinzi akakosha nezveActive DAS:
Sisitimu yeDistributed Antenna System (DAS): DAS inovandudza kufukidzwa kwemasaini ekutaurirana nefoni uye mhando yayo nekuisa ma antenna nodes akawanda mukati mezvivakwa kana nzvimbo. Inogadzirisa mipata yekufukidzwa muzvivakwa zvikuru, nhandare dzemitambo, matunnel epasi pevhu, nezvimwewo. Kuti uwane rumwe ruzivo nezve Distributed Antenna Systems (DAS),ndapota tinya pano.
DAS Inoshanda Yekuvaka Mabhizinesi
1. Musiyano uripo pakati peActive nePassive DAS:
Active DAS: Inoshandisa ma amplifiers anobatsira kuwedzera masaini, zvichipa mukana wekuwedzera uye huwandu hwekufukidza panguva yekutumira masaini. Masisitimu aya anopa kuchinjika kwakanyanya uye kugona kuchinjika, zvichinyatso fukidza zvivakwa zvikuru kana zvakaoma.
Passive DAS: Haishandisi ma amplifiers; kutumira masaini kunoenderana nema passives akadai se feeders, couplers, uye splitters. Passive DAS yakakodzera kune zvinodiwa zvekufukidza zvidiki kusvika zvepakati, senge zvivako zvemahofisi kana nzvimbo diki dzekutengeserana.
Sisitimu yeActive Distributed Antenna System (DAS) inovandudza kufukidzwa kwemasaini asina waya uye kugona kwayo nekushandisa zvikamu zvemagetsi zvinoshanda kuti zviwedzere uye zviparadzire masaini muchivako kana nzvimbo yese. Heino mashandiro azvinoita:

Sisitimu yeActive Distributed Antenna System (DAS) inovandudza kufukidzwa kwemasaini asina waya uye kugona kwayo nekushandisa zvikamu zvemagetsi zvinoshanda kuti zviwedzere uye zviparadzire masaini muchivako kana nzvimbo yese. Heino mashandiro azvinoita:
Sisitimu yeAntenna Yakaparadzirwa Inoshanda (DAS)
Zvikamu
1. Chikamu Chemusoro-Mugumo:
- Nzvimbo yeBase Station: Inobatanidza nechiteshi chebase chemupi webasa asina waya.
- Kuchinja Chiratidzo: Kunoshandura chiratidzo cheRF kubva pachiteshi chepasi kuita chiratidzo che optical chekutumira kuburikidza netambo dze fiber optic.
Chikamu cheMusoro neChinotangira Kure
2. Tambo dzeFiber Optic:
- Tumira chiratidzo che optical kubva ku head-end unit kuenda kuma divi ari kure ari munzvimbo yese yekuvhara.
Chinodzokorodza Fiber Optic (DAS)
3. Zvikamu Zviri Kure:
- Kushandurwa kweRF kuenda kuOptical: Shandura chiratidzo cheoptical chidzoserwe kuita chiratidzo cheRF.
-Chinodzokorodza Fiber Optic: Wedzera simba reRF rechiratidzo kuti chifukidzwe.
- MaAntena: Govera chiratidzo cheRF chakakwidziridzwa kune vashandisi vekupedzisira.
4. MaAntena:
- Yakaiswa zvine hungwaru muchivako chose kana munzvimbo yese kuitira kuti zviratidzo zviparadzirwe zvakaenzana.
Maitiro Ekushanda
1. Kugamuchira Chiratidzo:
- Chikamu chemagetsi chinopa chiratidzo cheRF kubva kumupi webasa'chiteshi chepasi.
2. Kushandurwa kweChiratidzo uye Kutumirwa:
- Chiratidzo cheRF chinoshandurwa kuita chiratidzo che optical uye chinotumirwa kuburikidza netambo dze fiber optic kuenda kumayuniti ari kure.
3. Kuwedzera uye Kugovera Zviratidzo:
- Mayuniti ari kure anoshandura chiratidzo che optical kuita chiratidzo cheRF, ochisimudzira, uye ochiparadzira kuburikidza nema antenna akabatana.
4. Kubatana kweMushandisi:
- Midziyo yevashandisi inobatanidza kune antenna dzakapararira, zvichigamuchira chiratidzo chakasimba uye chakajeka.
Mabhenefiti
- Kufukidzwa Kwakavandudzwa: Kunopa kufukidzwa kwakasimba uye kwakasimba kwechiratidzo munzvimbo dzisingasvike nharembozha dzechinyakare.
- Kugona Kwakawedzerwa: Inotsigira huwandu hwakawanda hwevashandisi nemidziyo nekuparadzira mutoro pamaantenna akawanda.
- Kuchinjika uye Kugona Kukura: Yakawedzerwa kana kugadziriswa zviri nyore kuti ienderane nezvinodiwa zvekuvhara zvinoshanduka.
- Kuderedzwa Kwekupindira: Nekushandisa maantenna akawanda ane simba shoma, zvinoderedza kupindira kunowanzobatanidzwa neantenna imwe chete ine simba guru.
Nyaya Dzekushandisa(Mapurojekiti aLintratek)
- Zvivako Zvikuru: Zvivako zvemahofisi, zvipatara, nemahotera uko masaini efoni anobva kunze angasapinda zvakanaka.
- Nzvimbo Dzeveruzhinji: Nhandare dzemitambo, nhandare dzendege, nenzvimbo dzemisangano uko vanhu vakawanda vanoda kuvharwa kwakasimba kwezviratidzo.
- Nzvimbo dzeMaguta: Nzvimbo dzakamanikana dzemaguta uko zvivakwa nezvimwe zvivakwa zvinogona kuvharira masaini emagetsi echinyakare.
Nzvimbo yekupaka mota pasi pevhu(DAS)
Active DAS inoshanda nekushandisa musanganiswa we tekinoroji dze optical neRF kuti iwedzere uye iparadzire masaini asina waya zvinobudirira, ichipa kufukidzwa kwakavimbika uye kugona munzvimbo dzakaoma.
Hofisi huru yeLintratek
Lintratekanga ari mugadziri wehunyanzvi weDAS (Sisitimu yeAntena Yakaparadzirwa) nemidziyo inobatanidza R&D, kugadzirwa, uye kutengeswa kwemakore gumi nemaviri. Zvigadzirwa zvinofukidza masaini mumunda wekutaurirana nefoni: zvinosimudzira masaini efoni, maantenna, masplitter emagetsi, macouplers, nezvimwewo.
