Measurement Error Evaluation I The calculation follows the steps recommended in ref(3), section 4.2.2. From the factors considered in 4.2.2 only the factorsaffecting beamwidth measurement were accounted. The main contributor to the error is the chamber and because the antenna is moving during the measurement it was considered as recommended in all references.

Chamber Certification Data I Measurement of shielding attenuation according to Results EN 50147-1 The shielding attenuation measurement at the specified measurement points (see figure 5.1 -5.2) showed that the enclosure keeps the specified attenuation values. Restricted © Siemens Mobility GmbH 2019 Page 29 February2019 MO TI SPA RFS

Chamber Certification Data II Reflectivity Performance (Quiet Zone) Results At 0.80 GHz, the worst-case signal level was measured to be -36 dB while the specified (expected) reflectivity at the same frequency had been set to be better than -25 dB. At 3.00 GHz, the worst-case signal level was measured to be -52.3 dB while the specified (expected) reflectivity at the same frequency had been set to be better than -41 dB. At 10.0 GHz, the worst-case signal level was measured to be -50 dB while the specified (expected) reflectivity at the same frequency had been set to be better than -47 dB. The measurement results show that the installed chamber possesses better reflectivity levels than the expected ones in the design phase. Hence, the results for the antenna patterns measured in this chamber will have lower uncertainty levels than the ones expected.
