1.Overview
1.1 Introduction
E70-DTU (433NW30-GPRS) is a wireless modem to GPRS network server, which realizes the transparent
transmission of Sub-1G and GPRS network data. The star network module integrates the host (coordinator) and
the terminal into one, and includes long-distance and high-rate transmission modes. One host (coordinator)
supports up to 200 nodes to communicate with it, without having to deal with cumbersome networking. The
agreement solves a series of problems caused by the inability of concurrent 433MHz wireless data transmission.
At the same time, the module has built-in power amplifier (PA) and low noise amplifier (LNA), the measured
communication distance can reach 6.5km. On the GPRS network side, the radio supports
LTE-FDD/LTE-TDD/WCDMA/TD-SCDMA/CDMA/GSM wireless communication data transmission,
supporting LTE-FDD, LTE-TDD, DC-HSDPA, HSPA+, HSDPA, HSUPA, WCDMA, TD-SCDMA, CDMA,
EDGE and GPRS network data connections.
E70-DTU (433NW30-GPRS) can be directly connected to the computer host computer through USB cable
and parameter configuration. User-defined parameters can be easily changed without installing a driver. This chapter is a quick
introduction to the E70-DTU (433NW30-GPRS) product. It is the easiest hardware environment to test the E70-DTU (433NW30-GPRS)
network transmission function, which is to realize the two-way transparent transmission of data from the RF module to the network server.
