(Dongguan) 1 RF OUTPUT POWER Report No.: DG1221220-62768E-22A Definition The RF output power is defined as the mean equivalent isotropic radiated power (e.i.r.p.) of the equipment during a transmission burst. Limit The RF output power for non-FHSS equipment shall be equal to or less than 20 dBm. For Non-adaptive FHSS equipment, the manufacturer may have declared a reduced RF Output Power (see clause 5.4.1 m)) and associated Duty Cycle (see clause 5.4.1 e)) that will ensure that the equipment meets the requirement for the Medium Utilization (MU) factor further described in clause 4.3.2.5. This is verified by the conformance test referred to in clause 4.3.2.5.4. For non-adaptive non-FHSS equipment, where the manufacturer has declared an RF output power of less than 20 dBm e.i.r.p., the RF output power shall be equal to or less than that declared value. This limit shall apply for any combination of power level and intended antenna assembly. Test Procedure The test procedure shall be as follows: Step 1: ·Use a fast power sensor suitable for 2,4 GHz and capable of minimum 1 MS/s. ·Use the following settings: - Sample speed 1 MS/s or faster. - The samples shall represent the RMS power of the signal. - Measurement duration: For non-adaptive equipment: equal to the observation period defined in clause 4.3.1.3.2 or clause 4.3.2.4.2. For adaptive equipment, the measurement duration shall be long enough to ensure a minimum number of bursts (at least 10) are captured. For adaptive equipment, to increase the measurement accuracy, a higher number of bursts may be used. Step 2: ·For conducted measurements on devices with one transmit chain: - Connect the power sensor to the transmit port, sample the transmit signal and store the raw data. Use these stored samples in all following steps. ·For conducted measurements on devices with multiple transmit chains: - Connect one power sensor to each transmit port for a synchronous measurement on all transmit ports. - Trigger the power sensors so that they start sampling at the same time. Make sure the time difference between the samples of all sensors is less than 500 ns. - For each individual sampling point (time domain), sum the coincident power samples of all ports and store them. Use these summed samples in all following steps. Page 12 of 33 Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: DG1221220-62768E-22A Step 3: ·Find the start and stop times of each burst in the stored measurement samples. The start and stop times are defined as the points where the power is at least 30 dB below the highest value of the stored samples in step 2. In case of insufficient dynamic range, the value of 30 dB may need to be reduced appropriately. Step 4: ·Between the start and stop times of each individual burst calculate the RMS power over the burst using the formula below. The start and stop points shall be included. Save these Pburst values, as well as the start and stop times for each burst. Pburst 1 k k Psample (n) n 1 with 'k' being the total number of samples and 'n' the actual sample number Step 5: ·The highest of all Pburst values (value "A" in dBm) will be used for maximum e.i.r.p. calculations. Step 6: ·Add the (stated) antenna assembly gain "G" in dBi of the individual antenna. ·If applicable, add the additional beamforming gain "Y" in dB. ·If more than one antenna assembly is intended for this power setting, the maximum overall antenna gain (G orG + Y) shall be used. ·The RF Output Power (P) shall be calculated using the formula below: P = A + G + Y ·This value, which shall comply with the limit given in clause 4.3.1.2.3 or clause 4.3.2.2.3, shall be recorded in the test report.

Limit The maximum Power Spectral Density for non-FHSS equipment is 10 dBm per MHz. Test Procedure The transmitter shall be connected to a spectrum analyser and the Power Spectral Density as defined in clause 4.3.2.3shall be measured and recorded. The test procedure shall be as follows: Step 1: Connect the UUT to the spectrum analyser and use the following settings: ·Start Frequency: 2 400 MHz ·Stop Frequency: 2 483.5 MHz ·Resolution BW: 10 kHz ·Video BW: 30 kHz ·Sweep Points: > 8 350;for spectrum analysers not supporting this number of sweep points, the frequency band may be segmented NOTE: For spectrum analysers not supporting this number of sweep points, the frequency band may be segmented. ·Detector: RMS ·Trace Mode: Max Hold ·Sweep time: For non-continuous transmissions: 2 × Channel Occupancy Time × number of sweep points For continuous transmissions:10 s; the sweep time may be increased further until a value where the sweep time has no impact on the RMS value of the signal. For non-continuous signals, wait for the trace to stabilize. Save the data (trace data) set to a file. Step 2: For conducted measurements on smart antenna systems using either operating mode 2 or operating mode 3 (see clause 5.3.2.2), repeat the measurement for each of the transmit ports. For each sampling point (frequency domain), add up the coincident power values (in mW) for the different transmit chains and use this as the new data set. Page 14 of 33 Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: DG1221220-62768E-22A Step 3: Add up the values for power for all the samples in the file using the formula below. PSum 1 k k n 1 Psample (n) with 'k' being the total number of samples and 'n' the actual sample number Step 4: Normalize the individual values for power (in dBm) so that the sum is equal to the RF Output Power (e.i.r.p.) measured in clause 5.3.2 and save the corrected data. The following formulas can be used: CCorr PSum Pe.i.r. p PSamplecorr (n) PSample (n) CCorr with 'n' being the actual sample number Step 5: Starting from the first sample PSamplecorr(n) (lowest frequency), add up the power (in mW) of the following samples representing a 1 MHz segment and record the results for power and position (i.e. sample #1 to sample #100). This is the Power Spectral Density (e.i.r.p.) for the first 1 MHz segment which shall be recorded. Step 6: Shift the start point of the samples added up in step 5 by one sample and repeat the procedure in step 5 (i.e. sample #2 to sample #101). Step 7: Repeat step 6 until the end of the data set and record the Power Spectral Density values for each of the 1 MHz segments. From all the recorded results, the highest value is the maximum Power Spectral Density for the UUT. This value, which shall comply with the limit given in clause 4.3.2.3.3, shall be recorded in the test report. Test Data Test Result: Compliant. Please refer to following tables.

Limit The Occupied Channel Bandwidth shall fall completely within the band given in clause 1. In addition, for non-adaptive equipment using wide band modulations other than FHSS and with e.i.r.p greater than10 dBm, the occupied channel bandwidth shall be less than 20 MHz. Test Procedure The measurement procedure shall be as follows: Step 1: Connect the UUT to the spectrum analyser and use the following settings: ·Centre Frequency: The centre frequency of the channel under test ·Resolution BW: ~ 1 % of the span without going below 1 % ·Video BW: 3 × RBW · Frequency Span for other types of equipment: 2 × Nominal Channel Bandwidth ·Detector Mode: RMS ·Trace Mode: Max Hold ·Sweep time: 1 s Step 2: Wait for the trace to stabilize. Find the peak value of the trace and place the analyser marker on this peak. Step 3: Use the 99 % bandwidth function of the spectrum analyser to measure the Occupied Channel Bandwidth of the UUT. This value shall be recorded. NOTE: Make sure that the power envelope is sufficiently above the noise floor of the analyser to avoid the noise signals left and right from the power envelope being taken into account by this measurement.

Limit For equipment that supports a PER or FER test to be performed, the minimum performance criterion shall be a PER or FER less than or equal to 10 %. For equipment that does not support a PER or a FER test to be performed, the minimum performance criterion shall be no loss of the wireless transmission function needed for the intended use of the equipment. While maintaining the minimum performance criteria as defined in clause 4.3.2.11.3, the blocking levels at specified frequency offsets shall be equal to or greater than the limits defined for the applicable receiver category provided in table 14, table 15 or table 16.
