Non-SDR (Software Defined Radio) Cover Letter Date: July 02, 2021 Refer to KDB 442812 D01 SDR apps Guide v02r03. The following six questions can be used for determining if a radio can elect to be, or must be an SDR. 1. Can the RF parameters of the device be altered through software? Yes - go to 2. No, not an SDR No 2. Can third parties not permitted by the Commission through specific filings modify, configure, or load different software, or make configuration settings to operate the device or host hardware radio frequency parameters (frequency range, modulation type, maximum output power or other radio parameters) in any other way than granted (or expected to be granted)? Yes, must be an SDR. No - go to 3. No 3. Is the device capable of operating in any other in any other way than granted, or will be, granted? Yes, - go to 4. No - go to 5. No 4. Is this a Part 15 client Device as defined in Section 15.202 (as opposed to a master device)? Yes, qualifies as a part 15 client devices - go to 5. No, must be an SDR. 5. Does the manufacturer elect SDR? Yes, elects to be an SDR. No, Not an SDR No Conclusion: According to the above questions reply, we can confirm this device (FCC ID: 2AXJ4RE600X & IC: 26583-RE600X) must be a Non-SDR. __________________ Name: Abby Liang Position: Regulatory Compliance Manager Date: 2021-07-02

Frequency Stability Measurement 7.7.1.Test Limit Manufactures of U-NII devices are responsible for ensuring frequency stability such that an emission is maintained within the band of operation under all conditions of normal operation as specified in the user’s manual. The transmitter center frequency tolerance shall be ±20 ppm maximum for the 5GHz band (IEEE 802.11 specification). 7.7.2.Test Procedure Used Frequency Stability Under Temperature Variations: The equipment under test was connected to an external AC or DC power supply and input rated voltage. RF output was connected to a frequency counter or spectrum analyzer via feed through attenuators. The EUT was placed inside the temperature chamber. Set the spectrum analyzer RBW low enough to obtain the desired frequency resolution and measure EUT 20°C operating frequency as reference frequency. Turn EUT off and set the chamber temperature to highest. After the temperature stabilized for approximately 30 minutes recorded the frequency. Repeat step measure with 10°C decreased per stage until the lowest temperature reached. Frequency Stability Under Voltage Variations: Set chamber temperature to 20°C. Use a variable AC power supply / DC power source to power the EUT and set the voltage to rated voltage. Set the spectrum analyzer RBW low enough to obtain the desired frequency resolution and recorded the frequency. Reduce the input voltage to specify extreme voltage variation (±15%) and endpoint, recordthe maximum frequency change.
