1.Overview
1.1
Introduction
E90-DTU (230SL30-GPRS) is a data transmission station from radio frequency
to GPRS network server, which realizes the transparent data transmission between
sub-1g and GPRS network. The sub-1g radio frequency transceiver is based on
SEMTECH SX1262 radio frequency chip and supports LoRa spread spectrum
technology. It is equipped with high-performance MCU internally, which enables the
module to have a variety of transmission modes. At the same time, the module is built
with power amplifier (PA) and low noise amplifier (LNA). At the network end of GPRS network, the radio supports
LTE-FDD/TTE-TDD /WCDMA/ TD-SCDMA /CDMA/GSM wireless communication data transmission, and supports
LTE-FDD, LTE-TDD, dc-HSDPA, HSPA+, HSDPA, HSUPA, WCDMA, TD-SCDMA, CDMA, EDGE and GPRS
network data connection.
E90-DTU (230SL30-GPRS) can be directly connected to the upper computer via USB cable for parameter
configuration, without the need to install the driver, it is easy to change user-defined parameters.
This chapter is a quick introduction to E90-DTU (230SL30-GPRS) products. It builds the simplest hardware
environment to test the network transmission function of E90-DTU (230SL30-GPRS), that is, to realize the two-way
transmission of data from RF module to the network server.
