7.1.3 Multiple Operator System Recommendations
As in any Unison system, a multiple operator (neutral host) system requires one pair
of fiber strands between each Main Hub and each Expansion Hub, and one Cat-5/6
cable between each Expansion Hub and each RAU. In situations where Hubs and/or
RAUs will be installed in the future to support the addition of frequency bands and/or
wireless Operators, it is advantageous to install the necessary cabling initially. Such
deployment typically leads to substantial cost savings over installing parallel cabling
at separate times.
7.1.4 Distance Requirements
The following table shows the distances between Unison components and related
equipment.
