2G/3G/4G Products

4G DTU is a widely used device for Data collection in the Internet of Things. DTU (Data Transfer Unit) is the abbreviation of Data transfer terminal in English. Compared with 5G DTU, 4G DTU offers better cost performance, and compared with NB-IoT products, it has better speed and wider network coverage. Especially, the 4G CAT1 DTU in 4G DTU has a price close to that of NB-IoT DTU. Although its rate is slower than that of ordinary 4G DTU, the rate is sufficient for RS485/RS232 to 4G iot applications.
Shanghai ZLAN 4G Dtus include the regular 4G DTU ZLAN8305, the 4G DTU ZLAN8305L with network port, and the ZLAN8305LN with P2P function. The 4G CAT1 DTU includes the module ZLSN8008 and the RS485/RS232 to 4G DTU ZLAN8308. And the edge computing gateway ZLAN8304N2 with 4 network ports, 5G DTU ZLAN8507, etc.
