Figure 3-7 Requirements for the vertical deviation angle of an RRU
(1) RRU
Issue ()
To ensure proper heat dissipation and waterproofing of the RRU, the RRU must be installed
with the ports at the bottom and the vertical deviation angle of the RRU must be less than
or equal to 10 degrees, as shown in
The side-mounted mode is recommended for RRUs on the main pole secured on a tower.
This installation mode allows multiple RRUs to be installed next to each other at the same
level on a pole. When the horizontal distance between the main and auxiliary poles on a
tower is equal to or greater than 810 mm (23.62 in.), the side-mounted mode is
recommended for installing RRUs on the auxiliary pole to meet the minimum clearance
requirements. Otherwise, the standard mode is recommended for installing RRUs on the
auxiliary pole.
