The EUT was placed on the rotating table 1.5 meters above the ground at a Fully Anechoic Room, the table was rotated 360 degrees. b. The EUT was set 3 meters away from the receiving antenna, which was mounted on the top of a antenna tower. c. The antenna is 1.5 meters above the ground. Both horizontal and vertical polarizations of the antenna are set to make the measurement. d. During the test, each emission was maximized by: having the EUT continuously working, investigated all operating modes, rotated about all 3 axis (X, Y & Z) and considered typical configuration to obtain worst position.
