"Active DAS" yog hais txog Active Distributed Antenna System. Cov thev naus laus zis no txhim kho cov teeb liab wireless them thiab lub peev xwm network. Nov yog qee cov ntsiab lus tseem ceeb ntawm Active DAS:
Distributed Antenna System (DAS): DAS txhim kho kev sib txuas lus ntawm lub xov tooj ntawm tes thiab kev ua haujlwm zoo los ntawm kev siv ntau lub kav hlau txais xov rau hauv cov tsev lossis thaj chaw. Nws hais txog cov kev pab cuam hauv cov tsev loj, chaw ntau pob, subway tunnels, thiab lwm yam.Rau cov ntsiab lus ntxiv ntawm Distributed Antenna Systems (DAS),thov nias ntawm no.
Active DAS rau Commercial Building
1.Qhov txawv ntawm Active thiab Passive DAS:
Active DAS: Siv lub tshuab ua kom nquag plias los txhawb cov teeb liab, muab kev nce ntxiv thiab kev pab cuam ntau dua thaum lub teeb liab kis tau tus mob. Cov tshuab no muaj kev hloov pauv tau yooj yim dua thiab yoog raws, ua tau zoo los npog cov vaj tsev loj lossis nyuaj.
Passive DAS: Tsis siv amplifiers; Cov teeb liab kis tau tus mob nyob ntawm passive xws li feeders, couplers, thiab splitters. Passive DAS yog qhov tsim nyog rau cov kev xav tau me me rau nruab nrab, xws li cov tsev ua haujlwm lossis chaw lag luam me.
Active Distributed Antenna System (DAS) txhim kho cov teeb liab wireless thiab muaj peev xwm los ntawm kev siv cov khoom siv hluav taws xob kom nthuav dav thiab faib cov teeb liab thoob plaws hauv ib lub tsev lossis cheeb tsam. Nov yog nws ua haujlwm li cas:

Active Distributed Antenna System (DAS)
Cheebtsam
1. Head-End Unit:
- Base Station Interface: Txuas mus rau lub chaw muab kev pabcuam wireless lub hauv paus chaw nres tsheb.
- Kev hloov pauv teeb liab: Hloov cov teeb liab RF los ntawm lub hauv paus chaw nres tsheb mus rau hauv lub teeb liab kho qhov muag rau kev sib kis ntawm fiber ntau optic cables.
Head-End thiab Chaw Taws Teeb
2. Fiber Optic Cables:
- Xa cov teeb liab kho qhov muag los ntawm lub taub hau-kawg mus rau cov chaw nyob deb nroog nyob thoob plaws hauv cheeb tsam.
Fiber Optic Repeater (DAS)
3. Tej thaj chaw deb:
- Kev hloov kho qhov muag rau RF: Hloov cov teeb liab kho qhov muag rov qab rau hauv RF teeb liab.
-Fiber Optic Repeater: Txhawb RF teeb liab lub zog rau kev pab them nqi.
- Kav hlau txais xov: Tshaj tawm cov teeb liab RF amplified rau cov neeg siv kawg.
4. Kav hlau txais xov:
- Tso tawm tswv yim thoob plaws hauv lub tsev lossis cheeb tsam kom ntseeg tau tias cov teeb liab sib txawv.
Kev Ua Haujlwm
1. Teeb liab txais:
- Lub taub hau-kawg tau txais RF teeb liab los ntawm tus muab kev pabcuam's base chaw nres tsheb.
2. Kev hloov pauv thiab xa tawm teeb liab:
- Lub teeb liab RF tau hloov mus rau hauv lub teeb liab kho qhov muag thiab xa tawm ntawm fiber ntau optic cables mus rau tej thaj chaw deb.
3. Teeb liab Amplification thiab Distribution:
- Cov chaw taws teeb hloov pauv cov teeb liab kho qhov muag rov qab rau hauv RF teeb liab, ua kom nrov nrov, thiab faib nws los ntawm cov kav hlau txais xov txuas.
4. Cov neeg siv kev sib txuas:
- Cov neeg siv khoom siv txuas mus rau cov kav hlau txais xov xa tawm, tau txais lub teeb liab muaj zog thiab meej.
Cov txiaj ntsig
- Txhim Kho Kev Pabcuam: Muab cov teeb liab sib xws thiab muaj zog hauv thaj chaw uas cov xov tooj ntawm tes yuav tsis ncav cuag tau zoo.
- Txhim kho lub peev xwm: Txhawb ntau tus neeg siv thiab cov khoom siv los ntawm kev faib cov khoom hla ntau lub kav hlau txais xov.
- Flexibility thiab Scalability: Yooj yim nthuav los yog kho dua tshiab kom tau raws li cov kev xav tau hloov pauv.
- Txo kev cuam tshuam: Los ntawm kev siv ntau lub kav hlau txais xov qis, nws txo qhov cuam tshuam feem ntau cuam tshuam nrog ib lub kav hlau txais xov siab.
Siv Cases(Lintratek's Projects)
- Cov Tsev Loj: Cov tsev ua haujlwm, tsev kho mob, thiab tsev so uas cov xov tooj ntawm tes los ntawm sab nraud tuaj yeem nkag mus tsis tau zoo.
- Cov chaw pej xeem: chaw ntau pob, tshav dav hlau, thiab cov chaw sib tham uas cov neeg siv ceev ceev yuav tsum muaj kev tiv thaiv zoo.
- Cov cheeb tsam hauv nroog: Cov cheeb tsam hauv nroog ntom ntom uas cov tsev thiab lwm cov qauv tuaj yeem thaiv cov cim ntawm tes.
Active DAS ua haujlwm los ntawm kev siv cov khoom siv kho qhov muag thiab RF thev naus laus zis kom nthuav dav thiab faib cov cim wireless kom zoo, muab kev pabcuam txhim khu kev qha thiab muaj peev xwm hauv cov cheeb tsam nyuaj.
Lintratek Head Office
Lintratektau ua tus kws tsim khoom ntawm DAS (Distributed Antenna System) nrog cov khoom siv sib xyaw R & D, ntau lawm, thiab muag khoom rau 12 xyoos. Cov khoom siv hluav taws xob hauv kev sib txuas lus hauv xov tooj: xov tooj ntawm tes teeb liab boosters, antennas, fais fab splitters, couplers, thiab lwm yam.
