Table 7-1: Hazard Distance for Point to Multi Point
When using the system for point-to-multi-point
applications, all outdoor units must be
installed with a separation distance of at least 20 cm from all persons during normal
operation.
For a base station or any installation consisting of more than one outdoor unit (AU or
SU) the safety distance for all persons should be at least 2 meters.
