Ikati. iyi-UE-Category. Ngokwencazelo ye-3GPP, i-UE-Category ihlukaniswe ngamaleveli ayi-10 ukusuka ku-1 kuye ku-10.
I-Cat.1-5 ichazwa ngokuthi i-R8, i-Cat.6-8 ichazwa ngo-R10, kanti i-Cat.9-10 ichazwa ngo-R11.
I-UE-Category ichaza ngokuyinhloko amanani e-uplink ne-downlink imishini yetheminali ye-UE engakwazi ukusekela.
Iyini i-LTE Cat.1?
I-LTE Cat.1 (igama eligcwele lithi i-LTEUE-Isigaba 1), lapho i-UE ibhekisela kumishini yomsebenzisi, okuyisigaba sokusebenza okungenantambo kwemishini yetheminali yomsebenzisi ngaphansi kwenethiwekhi ye-LTE. I-Cat.1 iwukusebenzisa i-inthanethi Yezinto futhi ibone ukusetshenziswa kwamandla okuphansi kanye nokuxhumeka kwe-LTE okungabizi kakhulu, okubaluleke kakhulu ekuthuthukisweni kwe-inthanethi Yezinto.
I-LTE Cat 1, ngezinye izikhathi futhi ibhekisela njenge-4G Cat 1, yakhelwe ngokukhethekile izinhlelo zokusebenza ze-Machine-to-Machine (M2M) IoT. Ubuchwepheshe bethulwa okokuqala ku-3GPP Release 8 ngo-2009 futhi sebufana nobuchwepheshe bokuxhumana be-LTE IoT kusukela lapho. Isekela isivinini esiphezulu se-downlink se-10 Mbit / s kanye nesivinini se-uplink se-5Mbit / s futhi kukholakala ukuthi isisombululo esihle sezimo ezingaxhomekile ekudlulisweni kwedatha ngesivinini esiphezulu kodwa zisadinga ukwethembeka kwenethiwekhi ye-4G. Inganikeza ukusebenza kwenethiwekhi okuhle kakhulu, ukwethembeka okukhulu, ukumbozwa okuphephile kanye nokusebenza kwezindleko ezifanele.
I-LTE Cat.1 vs LTE Cat.NB-1
Ngaphansi kwezidingo zezinhlelo zokusebenza ze-IoT, i-3GPP Release 13 ichaza amazinga e-Cat M1 kanye ne-CatNB-1 (NB-IoT) ukuze kuhlangatshezwane nezidingo zezimakethe ze-IoT ezisezingeni elimaphakathi nezinezinga eliphansi ngokulandelanayo. Izinzuzo zobuchwepheshe ze-NB-IoT zingahlangabezana ngokugcwele nezidingo zezimo zesilinganiso esiphansi esimile. Kodwa ngakolunye uhlangothi, ijubane nokuthembeka kwe-LTE Cat M akukuhle njengoba kulindelekile ekubhekaneni nezidingo ze-IoT zamadivayisi agqokekayo, amakhamera okuqapha, namadivayisi okulandelela izinto, okushiya igebe lobuchwepheshe emkhakheni wokuxhumana kwe-IoT esezingeni eliphakathi. .
Nokho, i-LTE Cat.1 isekela i-downlink engu-10 Mbit/s kanye nesivinini esingu-5Mbit/s uplink, esifinyelela amanani aphezulu edatha ubuchwepheshe be-LTE Cat M kanye ne-NB-IoT obungeke bukwazi ukuwafinyelela. Lokhu kuphushe izinkampani eziningi ze-IoT ukuthi zisebenzise kancane kancane ubuchwepheshe be-LTE Cat 1 osebuvele butholakala.
Muva nje, i-Feasycom isungule i-LTE Cat.1 imojuli engenantambo ye-FSC-CL4010, ingasetshenziswa kabanzi ku-: smart wear, i-POS, iphrinta ephathekayo, i-OBD, ithuluzi lokuxilonga imoto, indawo yemoto, imishini yokwabelana, isistimu ye-intercom ehlakaniphile njalonjalo.
