INTRODUCTION

TO EMS

This section introduces the ADC Digivance Element Management System (EMS)

for Software-Defined Radio (SDR) Application.

1.1 General Description

EMS is a software application that provides control and monitoring functions for

network elements in a Digivance Long Range Coverage Solution (LRCS) network.

These network elements are of two types, host units and remote units, which in an

operational state exist as “host/remote pairs.” In an SDR application, the host unit

consists of an ADC card in the BTS (Base Transceiver Station) server. Figure 1

shows the main components in a working system.
