2.8.2. Logical Addresses and System Components
The BEAMER® system setup treats the system block diagram as a hierarchy tree, with the
BTS at the top and the BEAMER® modules at the bottom.
Figure 20: BEAMER® system entities and their logical relationships
The figure above shows the logical entities for a BEAMER® system. The top left block can
be used as a legend: each entity is defined by its name, its available address range, and its
actual address.
The figure shows a BTS, connected to four ICUs. Each ICU is connected to three physical
arrays (for simplicity, the tree is expanded for one ICU and one array only). Each array
consists logically of three sub-arrays (Bias-Ts): two Rx sub-array and one Tx sub-array.
Each Rx sub-array connects logically to two Rx BEAMER® controllers. This connection
logically controls both the BEAMER® Rx board and the BEAMER® Tx board. The Tx sub-
array has a dummy logical relation with the Tx- BEAMER® module, since its actual logical
control is via the Rx- BEAMER® block (this relation is shown as dashed line). However, the
Tx- BEAMER® has actual physical relation with the Tx sub-array, by virtue of the RF
connection between them.
The actual logical addresses shown on the figure were chosen from the available address
range and are actually arbitrary. However, with the ICU Bias-T organization it is easier to
group the Bias-Ts as Rx1,Rx2,Tx per array. In other words, the following sub-arrays groups
should be assigned for each array (sector):
Sub-arrays (1,2,3) - array #1
Sub-arrays (4,5,6) - array#2
Sub-arrays (7,8,9) - array#3
