MODELS DIFFERENCES DESCRIPTION FCC ID: XRAFB504 / IC: 8542A-FB504 (model: FB504) has the same board design and mechanical design as FCC ID: XRAFB505 / IC: 8542A-FB505 (model: FB505). The difference is that the Model: FB504 does not have the NFC controller and antenna is depopulated. Only model: FB505 output power was tested in this test report. Model: FB504 output power test results are leveraged from model: FB505 for this Class II Permissive Change application. 5.3. DESCRIPTION OF CLASS II PERMISSIVE CHANGE 802.11b mode average output power was decreased. 5.4. MAXIMUM OUTPUT POWER The transmitter has a maximum average conducted output power as follows: Frequency Range Output Power Output Power Mode (MHz) (dBm) (mW) 802.11b 16.68 46.56 2412-2472 802.11g 18.98 79.07 802.11n HT20 18.90 77.62 5.5. DESCRIPTION OF AVAILABLE ANTENNAS Frequency Band Antenna Peak Gain (GHz) (dBi) 2.4 -11.30 5.6. SOFTWARE AND FIRMWARE The test utility software used during testing was Tera Term Ver 4.93. The firmware installed in the EUT during testing was Version 32.3.125.8. Page 8 of 17 UL VERIFICATION SERVICES INC.
