3.4 Installation Scenarios
An RRU can be installed on a pole, U-steel, angle steel, wall, or IFS06. Installation scenarios
must meet heat-dissipation and waterproofing requirements of the RRU.
Requirements for the Installation Scenarios
Method of installation:
l
To ensure the heat dissipation of the RRU and waterproofing of the ports at the bottom of
the RRU, the vertical deviation angle of an RRU must be less than or equal to 10 degrees,
as shown in
.
l
On a tower, an RRU can be installed on a pole, angle steel, or U-steel. U-steel and angle
steel support the standard or reverse installation of a single RRU only.
