Antenna Test Report The gain of each antenna is measured in a fully anechoic chamber certified by CTIA OTA. The individual gains of all antennas are then mathematically summed at the same spatial position (azimuth and elevation) across all points in a spherical antenna pattern, following the FCC KDB 662911 D01 guidelines to compute the directional antenna gain. 1.

Additionally, the BLE and Wi-Fi in FE02 now share a common antenna. Consequently, while the Wi-Fi antenna design and characteristics remain identical between the two models, the BZT data is unique to each.

There is no restriction limits for bandwidth. 5.2.2 Test Procedures 1. The testing follows FCC KDB 789033 D02 General UNII Test Procedures New Rules v02r01. Section C) Emission bandwidth. 2. Set RBW = approximately 1% of the emission bandwidth. 3. Set the VBW > RBW. 4. Detector = Peak. 5. Trace mode = max hold 6. Measure the maximum width of the emission that is 26 dB down from the peak of the emission. Compare this with the RBW setting of the analyzer. Readjust RBW and repeat measurement as needed until the RBW/EBW ratio is approximately 1%. 7. For 99% Bandwidth Measurement, the spectrum analyzer's resolution bandwidth (RBW) is set 1-5% of the emission bandwidth and set the Video bandwidth (VBW) ≥ 3 * RBW. 8. Measure and record the results in the test report. 5.2.3 Test Setup 5.2.4 Test Result of 26dB & 99% Occupied Bandwidth Please refer to Appendix B.
