2.1 Introduction
The basic components of an ION-B system (please refer to fi g. 2.1.) are the following:
• a Master Unit, able to bring the mobile signals from the BTS to different Remote Units and
vice-versa, thus remotising the distribution and collection of any mobile signals via fi beroptic
cables;
• a variable number of Remote Units, conveying and receiving mobile signals through low-
power antennas.
A brief introduction to the main components of the ION-B system’s Master and Remote
Units is presented in the following text. The details of each component can be found in the
subsequent sections of this manual.
