I c I Report No.: TCT1811072013 6.7. Dwell Time 6.7.1. Test Specification Test Requirement: FCC Part15 C Section 15.247 (a)(1) Test Method: ANSI C63.10:2013 The average time of occupancy on any channel shall not be greater than 0.4 seconds within a period of 0.4 Limit: seconds multiplied by the number of hopping channels employed. Test Setup: LZ_E__I &1 _ Test Mode: Hopping mode 1. The testing follows ANSI C€63.10:2013 Measurement Guidelines. 2. The RF output of EUT was connected to the spectrum analyzer by RF cable and attenuator. The path loss was compensated to the results for each measurement. 3. Set to the maximum power setting and enable the EUT transmit continuously. Test Procedure: 4. Enable the EUT hopping function. * 5. Use the following spectrum analyzer settings: Span = zero span, centered on a hopping channel; RBW shall be = channel spacing and where possible RBW should be set >> 1 / T, where T is the expected dwell time per channel; VBW2RBW; Sweep = as necessary to capture the entire dwell time per hopping channel; Detector function = peak; Trace = max hold. 6. Measure and record the results in the test report. Test Result: PASS 6.7.2. Test Instruments Equipment Manufacturer Model Serial Number Calibration Due Spectrum Analyzer Agilent N9020A MY49100619 Sep. 20, 2019 RF Cable TCT RE—06 N/A Sep. 20, 2019 (9KHz—26.5GHz) Antenna Connector TCT RFC—01 N/A Sep. 20, 2019 Note: The calibration interval of the above test instruments is 12 months and the calibrations aretraceable to International system unit (S1).

In normal mode, hopping rate is 1600 hops/s with 6 slots in 79 hopping channels. For DH1, With channel hopping rate (1600 / 2 / 79) in Occupancy Time Limit (0.4 x 79) (s), Hops Over Occupancy Time comes to (1600 / 2 / 79) x (0.4 x 79) = 320 hops For DH3, With channel hopping rate (1600 / 6 / 79) in Occupancy Time Limit (0.4 x 79) (s), Hops Over Occupancy Time comes to (1600 / 4 / 79) x (0.4 x 79) = 160 hops For DH5, With channel hopping rate (1600 / 6 / 79) in Occupancy Time Limit (0.4 x 79) (s), Hops Over Occupancy Time comes to (1600 / 6 / 79) x (0.4 x 79) = 106.67 hops 2.
