1.2.1. BEAMER® Family Modular Concept
The BEAMER® family of products is modular. Each member can be attached to other
modules to establish a new product, matched to specific customer requirements. This
concept is illustrated in the following figure.

Figure 3: BEAMER® family modular concept
The BEAMER® can be used as a standalone antenna element for distributed antenna
purposes or stacked to form an antenna array. The BEAMER® and the BEAMER® Array
can be either connected with a pair of coaxial cables to a modified base station or converted
to match existing CATV infrastructure or fiber optic infrastructure.
1.3. Overview of the Interface and Control Unit (ICU)
The BEAMER® system consists of two parts:
• BEAMER® Active Radiating Module Array System
• ICU (Interface and Control Unit) - the interface between the BTS (Base Transceiver Station) and
the BEAMER® .
1.3.1. Interface and Control Unit - ICU
The ICU interfaces between the BEAMER® system and the BTS, provides the BEAMER®
system with the DC power, and controls each individual BEAMER® within any array. It
consists of a set of Bias T connections for multiplexing the DC power and the monitoring and
