1. Introduction

E90-DTU (170L30) is a data transmission station that adopts extremely advanced ultra -narrow band modulation

technology. On the original basis, power amplifier (PA) and low n oise amplifier (LNA) are built in, so that the maximu m

transmitting power reaches 1w and the receiv ing sensitivity is also imp roved to a certain extent. Co mpared with the

products without power amplifier and low noise amplifier, the overall co mmun ication s tability is greatly improved.

Different from analog FM stations and modems, digital radio provides transparent RS232/RS485 interface.

The station works in 170MHz frequency band and the communication d istance can reach 8km. Wireless digital

radio as a mediu m o f co mmunicat ion, as well as optical fiber, microwave, open wire, there is a certain scope of

application: it provides some special conditions, private network monitoring signals in real-time and reliable data

transmission, low cost, easy installation and maintenance, diffract ion capability is strong, flexible network structure, the

coverage is far characteristic, suitable for some more and occasions, such as dispersion and complex geographical

environment with PLC, RTU, rain gauge, level gauge and other data terminal is connected.
