1. Introduction
This chapter mainly introduces the overview and specification of the Tersus
Radio RS400H3-A.
1.1 Overview
The Tersus RS400H3-A radio is a base radio solution for wireless applications.
It provides reliable data communications for mission-critical applications where
a combination of stability, superior performance and long range are required.
The RS400H3-A provides high speed, high power, wireless data links and has
been designed to survive the rigors of GNSS/RTK surveying and precise
positioning applications. Up to 35W transmit power maximizes range and
supports operation in difficult urban areas. The RS400H3-A is equipped with
OLED display and keypads which are used for checking the operating status,
changing the operating channel, and transmitting power level.
