1.Overview
1.1 Introduction
E90-DTU (400SL22-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 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 (400SL22-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 (400SL22-GPRS) products. It builds the simplest hardware
environment to test the network transmission function of E90-DTU (400SL22-GPRS), that is, to realize the two-way
transmission of data from RF module to the network server.
