Kingtone Mobile SignalRepeater/Booster/Amplifier yog cov khoom lag luam saum toj kawg nkaus uas txhawb nqa ntau zaus (B20 800 & B3 1800 ).Lub adjustable tswj tag nrho koj los hloov koj lub teeb liab nyiam rau smoother lub suab thiab cov ntaub ntawv kis tau tus mob.Kev paub txog kev txhim kho lub teeb liab lub zog tsis hais koj lub xov tooj tam sim no kev pab them nqi zog lossis zaus band!
Ua ntej yuav thov nco ntsoov!
1. Xyuas kom tseeb tias qhov zaus band ntawm koj tus cab kuj haum rau cov khoom no.Txwv tsis pub lub cuab yeej ua haujlwm tsis tau rau koj.Yog hais tias koj tsis yog li ntawd clear qhov zaus ntawm koj lub xov tooj, koj yuav nias qhov txuas no
www.frequencycheck.com txhawm rau txheeb xyuas qhov zaus ntawm koj cov neeg nqa khoom.
2. Nco ntsoov tias koj tuaj yeem tau txais cov teeb liab zoo uas koj xav kom nthuav dav ntawm koj lub tsev sab nraud.Uas yuav tsum tau txais 3 ~ 5 bar teeb liab (-70dB ~ 90dB teeb liab zog) ntawm koj lub xov tooj ntawm tes.Thov nco ntsoov tias lub teeb liab txhawb nqa tuaj yeem txhawb nqa lub xov tooj ntawm tes network teeb liab, tab sis nws tsis pab tsim cov teeb liab.Piv txwv li, yog tias koj lub teeb liab sab nraud muaj 0 bar, nws tsis tuaj yeem ua haujlwm lossis nqa koj lub teeb liab.Hauv qab no yog cov txheej txheem ntawm kev txheeb xyuas lub xov tooj ntawm tes teeb liab lub zog.
Daim ntawv thov
Txhawm rau nthuav cov teeb liab kev pab them nqi ntawm cov teeb liab qhov muag tsis pom qhov chaw teeb liab tsis muaj zog
los yog tsis muaj.
Sab nraum zoov: tshav dav hlau, Tourism Regions, Golf Course, Tunnels, Factories, Mining Districts, Zos thiab lwm yam.
Sab hauv: Chaw ntiav pw, Exhibition Centers, Basements, Khw
Malls, Chaw Ua Haujlwm, Ntim Ntau thiab lwm yam.
