• On a pole
• In a 19 inch rack
The distance between MU and RRU-N is limited by the maximum length of the
optical fiber connecting the two units, which is 500 m. The RBS 2111 Second
Generation supports a length up to 3 km.
Note: When mounting the MU on a pole, it is recommended that the front
sunshield is positioned such that the MU is protected from the sun as
much as possible.
4.1 Space Requirements for Wall-Mounting of MU
This section describes the installation requirements, drill pattern and site layout.
4.1.1 Installation Requirements for Wall-Mounting
The MU must always be vertically mounted.
The wall must have a fairly level surface. The wall gradient must not exceed
5 mm/m.
The drill patterns are shown in the figures below. A drilling template for
wall-mounting is delivered with the wall-mounting kit for the MU.
