Kingtone tau siv cov kev daws teeb meem sab hauv tsev rau cov thev naus laus zis sib txawv txij li xyoo 2011: xov tooj ntawm tes (2G, 3G, 4G), UHF, TETRA ... ob qho tib si rail thiab txoj kev.
TETRA (Terrestrial Trunked Radio) thev naus laus zis tau siv thoob plaws ntiaj teb
Hauv qee lub sijhawm, koj yuav xav tau lub zog hluav taws xob ntxiv.Piv txwv li, yog tias koj cov neeg ua haujlwm ua haujlwm hauv cov chaw nres nkoj uas nyob ib puag ncig los ntawm cov chaw tsim khoom lag luam lossis saib xyuas qhov chaw hauv av, cov khoom siv hauv tsev tuab (feem ntau yog pob zeb lossis cov phab ntsa steel) tuaj yeem ua qhov thaiv thiab thaiv cov teeb liab.Qhov no yuav luag yuav luag ncua kev sib txuas lus thiab hauv qee qhov, tiv thaiv tus neeg siv los ntawm kev xa thiab tau txais cov ntaub ntawv tag nrho.
Txhim khu kev qha ntawv kev nyab xeeb wireless network
Cov thev naus laus zis ntxiv uas peb muab los ua kom ntseeg tau tias muaj kev sib txuas hauv ib puag ncig zoo li no muaj cov rov ua dua los txhawb cov teeb liab ntau yam nrog DAS (Distributed Antenna Systems).Qhov no muab kev daws teeb meem thaum kev sib txuas tsis zoo yog qhov teeb meem.Nws tuaj yeem xa mus rau cov chav tsev me me tshaj plaws rau cov tsev tsim khoom loj tshaj plaws.

Qhov loj ntawm lub tsev yeej txiav txim siab seb hom tshuaj twg koj yuav muaj.
Nws yuav yog BDA [bidirectional amplifier] rau cov tsev me, tab sis rau cov tsev loj uas tsis yog kev daws teeb meem, yog li koj yuav tsum mus nrog fiber-optic DAS.
Cov thev naus laus zis ua haujlwm hauv kev teeb tsa hauv tsev tuaj yeem muaj los ntawm qhov yooj yim off-air relay coj lub teeb liab los ntawm sab nraud mus rau lub kav hlau txais xov sib txuas (DAS).
Nws yog ib lub network uas ntes cov teeb liab TETRA los ntawm sab nraum lub tsev, ua kom nws nrov nrov thiab txhaj tshuaj rau hauv lawv los ntawm kev siv DAS (xa khoom kav hlau txais xov).
