Pseudorandom Frequency Hopping Sequence Test Requirement: FCC Part15 C Section 15.247 (a)(1) requirement: Frequency hopping systems shall have hopping channel carrier frequencies separated by a minimum of 25 kHz or the 20 dB bandwidth of the hopping channel, whichever is greater. Alternatively. Frequency hopping systems operating in the 2400-2483.5 MHz band may have hopping channel carrier frequencies that are separated by 25 kHz or two-thirds of the 20 dB bandwidth of the hopping channel, whichever is greater, provided the systems operate with an output power no greater than 125 mW. The system shall hop to channel frequencies that are selected at the system hopping rate from a Pseudorandom ordered list of hopping frequencies. Each frequency must be used equally on the average by each transmitter. The system receivers shall have input bandwidths that match the hopping channel bandwidths of their corresponding transmitters and shall shift frequencies in synchronization with the transmitted signals. EUT Pseudorandom Frequency Hopping Sequence The pseudorandom sequence may be generated in a nine-stage shift register whose 5th and 9th stage outputs are added in a modulo-two addition stage. And the result is fed back to the input of the first stage. The sequence begins with the first one of 9 consecutive ones; i.e. the shift register is initialized with nine ones. • Number of shift register stages: 9 • Length of pseudo-random sequence: 2 9 -1 = 511 bits • Longest sequence of zeros: 8 (non-inverted signal) An example of Pseudorandom Frequency Hopping Sequence as follow: Each frequency used equally on the average by each transmitter.

The emission levels of other frequencies are very lower than the limit and not show in test report. 2. Measurements were conducted from 1 GHz to the 10th harmonic of highest fundamental frequency. 3. Data of measurement shown “---“in the above table mean that the reading of emissions is attenuated more than 20 dB below the limits or the field strength is too small to be measured. 4. Measurements were conducted in all three modulation (GFSK, Pi/4 DQPSK, 8DPSK), and the worst case Mode (8DPSK) was submitted only. 5. EUT has been tested in unfolded states, and the report only reflects data in the unfolded state (worst-case scenario) Note: Freq. = Emission frequency in MHz Reading level (dBμV) = Receiver reading Corr.

Factor (dB) Limit (dBμV) = Limit stated in standard Margin (dB) = Level (dBμV) – Limits (dBμV) Report No.: WSCT-ANAB-R&E251200100A-BT Issued Date: 08 January 2026 Page 77 of 78 6.11.3.
