Installing a pRRU3901 on a wall
The pRRU3901 must keep a minimum of 0.5 m away from the power equipment with interference,
and keep a minimum of 2 m away from the source with radiation.
The pRRU3901 must keep away from a metal wall to avoid the impact on the antenna performance.
When a pRRU3901 is installed on a wall, installation modes vary with the quality of wall, as
shown in Table 7-2.
