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 control communication on the RF
cables to the BEAMER
system, a modem for communicating with each of the BEAMER units, and a
digital processor/controller.
The ICU interfaces to the Tx and Rx RF connections in the BTS, to the Alarm concentrating unit in
the BTS, and has serial ports for a local host computer, for remote control, and for diagnostics. A set
of indicator lights visually reports the status of each BEAMER Array. The ICU can be remote
