Tesunho 3G 4G Wireless Transmitter and Receiver Serial GSM Modem for Data Transfer
Tesunho 3G 4G Wireless Transmitter and Receiver Serial GSM Modem for Data Transfer
DTU (Data Transfer unit)
It is a wireless terminal device specially designed to convert serial port data into IP data or convert IP data into serial port data for transmission over a wireless communication network.
DTU is an industrial-grade M2M wireless data transmission terminal. It is a key component of the IoT integrated application system. It uses the public wireless network to provide wireless data transmission services for users, and builds a bridge before data collection and application. More and more companies are choosing to use IoT wireless communication technology to increase system productivity, efficiency and cost effectiveness. Main application cases: power industry such as online transmission line monitoring, water industry such as remote monitoring of small rivers, industrial automation industry such as heat network monitoring, financial industry such as bank ATM network, transportation industry such as traffic flow detection.
