The radiation pattern was performed in a semi-anechoic chamber with size 9x9x19 m with absorbers on walls and ceiling, see fig 1 and 2. The distance between EUT and receive antenna was 3 m. The EUT antenna has circular polarization and the antenna pattern was therefore measured both for horizontal and vertical polarized E-field in the middle of the transmitter frequency band 1643.5 MHz. The radiation patterns are given on fig 5 and 6. From the diagram we can see that maximum field is at antenna boresight. The field strength is therefore measured at the antenna boresight, see fig 4. Test Equipment Used: 1, 4 4.2 Field strength exposure Because of the circular polarization of the transmitting antenna the E-field measurements are performed with linear antenna in 0 and 90 degree position to the EUT, horizontal and vertical, see fig 4. The total E-field is now given as power sum of the two measurements: Etot = (Ev2 + Eh2)½ The TDMA structure of the transmitter when measuring E-field is given on fig 7 and 8, this gives as duty cycle of 98.1 %. Measuring the E-field is done by using RMS reading power meter with integrating time 100 ms. During test the transmitter was set to give maximum transmitting power. The field is measured in the distance range from 25 cm to 100 cm from EUT. Test results: Distance cm E-field V/m 25 52.6 35 40.0 45 32.2 55 26.6 65 22.7 75 20.1 85 17.7 100 15.7 Table 1

This is equivalent to 61.3 V/m for plane wave. From table 1 we can see that at a distance of 25 cm the field intensity is < 1.0 mW/cm2, (0.73 mW/cm2) If we calculate the distance using 61.3 V/m as parameter we have: d =(30½x 8.2½)/61.3 = 0.255 m.
