Cat. yog UE-Category. Raws li lub ntsiab lus ntawm 3GPP, UE-Category muab faib ua 10 qib ntawm 1 txog 10.
Cat.1-5 yog txhais los ntawm R8, Cat.6-8 yog txhais los ntawm R10, thiab Cat.9-10 yog txhais los ntawm R11.
UE-Category feem ntau txhais cov uplink thiab downlink tus nqi uas UE cov khoom siv davhlau ya nyob twg tuaj yeem txhawb nqa.
LTE Cat.1 yog dab tsi?
LTE Cat.1 (lub npe tag nrho yog LTEUE-Category 1), qhov twg UE hais txog cov neeg siv khoom siv, uas yog kev faib tawm ntawm wireless kev ua haujlwm ntawm cov neeg siv khoom siv davhlau ya nyob twg hauv qab LTE network. Cat.1 yog ua haujlwm rau Is Taws Nem ntawm Yam thiab paub txog kev siv hluav taws xob tsawg thiab tus nqi qis LTE kev sib txuas, uas yog qhov tseem ceeb heev rau kev txhim kho Internet ntawm Yam.
LTE Cat 1, qee zaum kuj hais txog 4G Cat 1, tshwj xeeb yog tsim los rau Machine-to-Machine (M2M) IoT daim ntawv thov. Cov thev naus laus zis tau pib pib hauv 3GPP Tso Tawm 8 hauv 2009 thiab tau dhau los ua qauv LTE IoT kev sib txuas lus thev naus laus zis txij thaum ntawd los. Nws txhawb nqa qhov siab tshaj plaws downlink ceev ntawm 10 Mbit / s thiab uplink ceev ntawm 5Mbit / s thiab ntseeg tau tias qhov kev daws teeb meem zoo tshaj plaws rau cov xwm txheej uas tsis yog nyob ntawm cov ntaub ntawv xa mus ceev tab sis tseem xav tau kev ntseeg siab ntawm 4G network. Nws tuaj yeem muab kev ua haujlwm zoo hauv network, kev ntseeg tau zoo, kev tiv thaiv kev nyab xeeb thiab kev ua haujlwm zoo tshaj plaws.
LTE Cat.1 vs LTE Cat.NB-1
Raws li cov kev cai ntawm IoT daim ntawv thov, 3GPP Tso Tawm 13 txhais cov qauv Cat M1 thiab CatNB-1 (NB-IoT) kom tau raws li cov kev xav tau ntawm cov khoom lag luam nruab nrab thiab tus nqi qis IoT raws li. Cov txiaj ntsig zoo ntawm NB-IoT tuaj yeem ua tau raws li qhov xav tau ntawm cov xwm txheej qis qis qis. Tab sis ntawm qhov tod tes, qhov ceev thiab kev ntseeg siab ntawm LTE Cat M tsis zoo li qhov xav tau hauv kev hais txog IoT cov kev xav tau ntawm cov cuab yeej siv tau, lub koob yees duab soj ntsuam, thiab cov khoom siv thauj khoom taug qab, tawm hauv kev sib txawv hauv thaj chaw nruab nrab ntawm IoT kev sib txuas. .
Txawm li cas los xij, LTE Cat.1 txhawb nqa 10 Mbit / s downlink thiab 5Mbit / s uplink speeds, uas ua tiav cov ntaub ntawv siab dua uas LTE Cat M thiab NB-IoT thev naus laus zis tsis tuaj yeem ua tiav. Qhov no tau thawb ntau lub tuam txhab IoT kom maj mam siv LTE Cat 1 thev naus laus zis uas twb muaj lawm.
Tsis ntev los no, Feasycom tau tshaj tawm LTE Cat.1 wireless module FSC-CL4010, nws tuaj yeem siv dav hauv: ntse hnav, POS, lub tshuab luam ntawv portable, OBD, tsheb kuaj ntsuas, tsheb qhov chaw, sib koom cov cuab yeej, ntse intercom system thiab lwm yam.
