De ingebouwde SIM7020G-module dekt de meeste Cat-NB-frequentiebanden en integreert de SMA externe antenne-interface om de communicatiekwaliteit en signaalstabiliteit van het apparaat te verbeteren. In tegenstelling tot de DTU, die over het algemeen alleen de functie van transparante gegevensoverdracht heeft, heeft de ATOOM DTU-serie een meer open architectuurontwerp. De controller ATOOM LITE kan het programma naar believen aanpassen aan de werkelijke activiteiten, en de hele machine behoudt een verscheidenheid aan interfaces (RS485, I2C, aangepaste interface) voor gebruikers om uit te breiden, wat handig is voor de snelle toegang van sensoren en actuatoren. De op zichzelf staande klemstructuur van de geleiderail is perfect ingebed in verschillende industriële controlelocaties. ATOOM DTU NB is zeer geschikt voor diverse low-latency, low-throughput toepassingsscenario's (zoals afstandsbediening, asset tracking, remote monitoring, medische behandeling op afstand, deelfietsen, etc.).\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cb\u003eProducteigenschappen:\u003c\/b\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003eSIM7020G\/Globale
