Katsi. iri EU-Chikamu. Zvinoenderana netsanangudzo ye3GPP, UE-Chikamu chakakamurwa kuita gumi kubva pa10 kusvika pagumi.
Katsi.1-5 inotsanangurwa neR8, Katsi.6-8 inotsanangurwa neR10, uye Katsi.9-10 inotsanangurwa neR11.
UE-Chikamu chinonyanya kutsanangura iyo uplink uye downlink mitengo iyo UE terminal michina inogona kutsigira.
Chii chinonzi LTE Cat.1?
LTE Cat.1 (zita rizere ndiLTEUE-Chikamu 1), apo UE inoreva midziyo yemushandisi, inova kupatsanurwa kwewireless kuita kwemushandisi terminal michina pasi peLTE network. Cat.1 ndeyekushandira Indaneti yeZvinhu uye kuona kushandiswa kwesimba kwakaderera uye kudhura kweLTE connection, iyo inokosha zvikuru mukuvandudzwa kweInternet yezvinhu.
LTE Katsi 1, dzimwe nguva zvakare inoreva se4G Katsi 1, yakagadzirirwa chaizvo Machine-to-Machine (M2M) IoT application. Iyo tekinoroji yakatanga kuunzwa mu3GPP Release 8 muna 2009 uye yave yakamira LTE IoT yekutaurirana tekinoroji kubvira ipapo. Iyo inotsigira yakanyanya downlink kumhanya ye10 Mbit/s uye uplink kumhanya kwe5Mbit/s uye inotendwa yakanakira mhinduro yezviitiko izvo zvisingatsamiri pakufambiswa kwedata zvakanyanya asi zvichiri kuda kuvimbika kweiyo 4G network. Inogona kupa yakanakisa network kuita, kuvimbika kukuru, kufukidzwa kwakachengeteka uye kuita kwakaringana mutengo.
LTE Cat.1 vs LTE Cat.NB-1
Pasi pezvinodiwa zveIoT maapplication, 3GPP Release 13 inotsanangura iyo Katsi M1 neCatNB-1 (NB-IoT) zviyero kuti isangane nezvinodiwa zvepakati-mwero uye yakaderera-chiyero IoT misika zvichiteerana. Iyo tekinoroji mabhenefiti eNB-IoT anogona kuzadzisa zvizere zvidikanwi zve static yakaderera-reti mamiriro. Asi nerumwe rutivi, kumhanya uye kuvimbika kweLTE Cat M haina kunaka sezvaitarisirwa mukugadzirisa zvinodiwa neIoT zvezvishandiso zvinopfekwa, makamera ekutarisa, uye michina yekutevera zvinhu, zvichisiya gaka rehunyanzvi mumunda wepakati-mwero IoT yekubatanidza. .
Zvisinei, LTE Cat.1 inotsigira 10 Mbit/s downlink uye 5Mbit/s uplink kumhanya, iyo inowana yakakwirira data mazinga ayo LTE Cat M uye NB-IoT michina haigoni kubudirira. Izvi zvasundidzira makambani mazhinji eIoT kuti ashandise zvishoma nezvishoma LTE Cat 1 tekinoroji yatovepo.
Munguva ichangopfuura, Feasycom yakatanga LTE Cat.1 wireless module FSC-CL4010, inogona kushandiswa zvakanyanya mu: smart wear, POS, portable printer, OBD, chimbo chekuongorora motokari, nzvimbo yemotokari, kugoverana midziyo, intelligent intercom system nezvimwe zvakadaro.
