For best performance it is recommended to have a clearance zone around the mast. The clearance
zone depends on the surrounding environment and the antenna’s down tilt. If the mast is
surrounded by metal, then larger clearance is required compared to an environment where the
antenna is surrounded by foliage
l
SMs should be spread in azimuth of AP antenna
l
450m is susceptible to movement, for best MU- MIMO performance it is recommended that the
450m AP is mounted/installed on a mast that is extremely rigid (no movement and is vertical).
l
LINKPlanner can be used to plan SMs across the AP antenna azimuth
Link p lanning
This section describes factors to be considered when planning links, such as range, obstacles path loss and
throughput. LINKPlanner is recommended.
Rang e and ob st acles
Calculate the range of the link and identify any obstacles that may affect radio performance.
Perform a survey to identify all the obstructions (such as trees or buildings) in the path and to assess the
risk of interference. This information is necessary in order to achieve an accurate link feasibility
assessment.
