1.Dab tsi yog qhov kev faib kav hlau txais xov?
A Distributed Antenna System (DAS), tseem hu ua amobile signal boostersystem lossis cellular teeb liab txhim kho qhov system, yog siv los nthuav cov xov tooj ntawm tes lossis lwm yam teeb liab wireless. A DAS txhim kho cov xov tooj ntawm tes hauv tsev los ntawm kev siv peb lub ntsiab lus: lub teeb liab qhov chaw, teeb liab rov qab, thiab chav faib khoom hauv tsev. Nws nqa cov teeb liab ntawm tes los ntawm lub hauv paus chaw nres tsheb lossis ib puag ncig sab nraum zoov rau hauv qhov chaw sab hauv.

2.Vim li cas peb xav tau cov kav hlau txais xov xa khoom?
Cellular signals emissions los ntawm lub hauv paus chaw nres tsheb ntawm cov chaw muab kev sib txuas lus mobile yog feem ntau obstructed los ntawm lub tsev, hav zoov, roob, thiab lwm yam teeb meem, ua rau tsis muaj zog teeb liab cheeb tsam thiab cov chaw tuag. Tsis tas li ntawd, kev hloov pauv ntawm kev sib txuas lus thev naus laus zis los ntawm 2G mus rau 5G tau txhim kho tib neeg lub neej. Nrog rau txhua tiam ntawm kev sib txuas lus thev naus laus zis, cov ntaub ntawv kis tau tus nqi tau nce siab heev. Txawm li cas los xij, txhua qhov kev nce qib hauv kev sib txuas lus thev naus laus zis kuj tseem coj tau qee qib ntawm cov teeb liab propagation attenuation, uas yog txiav txim los ntawm cov cai ntawm lub cev.
Piv txwv li:
Spectrum yam ntxwv:
5G: Feem ntau yog siv cov kab hluav taws xob siab (millimeter nthwv dej), uas muab cov bandwidth ntau dua thiab nrawm dua tab sis muaj thaj tsam me me thiab tsis muaj zog nkag mus.
4G: Siv cov zaus qis dua, muab kev pabcuam ntau dua thiab muaj zog nkag mus.
Hauv qee qhov xwm txheej ntawm cov kab hluav taws xob siab, tus naj npawb ntawm 5G hauv paus chaw nres tsheb yuav yog tsib npaug ntawm 4G hauv paus chaw nres tsheb.
Yog li ntawd,niaj hnub loj tsev lossis hauv qab daus feem ntau xav tau DAS los xa xov tooj ntawm tes.
3. DAS Cov txiaj ntsig:
Smart Hospital Base ntawm DAS System
Txhim Kho Kev Pabcuam: Txhim kho cov teeb liab muaj zog hauv cov cheeb tsam uas tsis muaj zog lossis tsis muaj kev pab cuam.
Kev Tswj Peev Xwm: Txhawb ntau tus neeg siv los ntawm kev faib cov khoom thauj hla ntau lub kav hlau txais xov.
Txo kev cuam tshuam: Los ntawm kev siv ntau lub kav hlau txais xov qis, DAS txo kev cuam tshuam piv rau ib lub kav hlau txais xov siab.
Scalability: Muaj peev xwm scaled kom npog cov tsev me rau cov tsev kawm ntawv loj.
4.Cov teeb meem dab tsi tuaj yeem daws qhov DAS?
Smart Library Base ntawm DAS System
DAS feem ntau yog siv rau hauv cov chaw loj, cov tsev lag luam, tsev kho mob, cov chaw thauj mus los, thiab cov chaw sab nraum zoov uas muaj kev cuam tshuam thiab txhim khu kev qha wireless cellular teeb liab yog qhov tseem ceeb. Nws kuj tseem relays thiab amplifies cellular teeb liab bands siv los ntawm cov neeg nqa khoom sib txawv kom haum rau ntau yam khoom siv.
Nrog rau kev loj hlob ntawm lub thib tsib tiam mobile kev sib txuas lus thev naus laus zis (5G), qhov xav tau rau DAS kev xa tawm yog nce vim qhov tsis zoo nkag mus thiab muaj kev cuam tshuam siab rau kev cuam tshuam ntawm 5G millimeter nthwv dej (mmWave) hauv kev sib kis.
Kev xa DAS hauv cov tsev ua haujlwm, tsev kho mob, tsev kawm ntawv, khw muag khoom, thiab chaw ntau pob tuaj yeem muab kev kub ceev, qis-latency 5G network kev pabcuam thiab txhawb nqa ntau ntawm cov khoom siv txawb. Qhov no ua rau cov kev pabcuam cuam tshuam nrog 5G IoT thiab telemedicine.

5.Lintratek Profile thiab DAS
Lintratekua tauib tug kws tsim khoomntawm kev sib txuas lus txawb 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.
Lintrak's DAS System
Lintratek covDistributed Antenna System (DAS)Feem ntau cia siab rau fiber ntau optic repeaters. Qhov system no xyuas kom meejkis tau tus mob mus ntevntawm cellular signals tshaj 30 kilometers thiab txhawb customization rau ntau yam cellular zaus bands. Lintratek's DAS tuaj yeem hloov kho rau cov ntawv thov sib txawv raws li cov neeg siv khoom xav tau, suav nrog cov tsev lag luam, chaw nres tsheb hauv av, thaj chaw siv hluav taws xob, cov chaw tsim khoom, thaj chaw deb, thiab lwm yam. Hauv qab no yog qee qhov piv txwv ntawm Lintratek's DAS lossis xov tooj ntawm tes teeb liab txhawb kev ua haujlwm.
