NiceRF Wireless Technology LTD. FCC Modular Approval Request Rev 4.0 Federal Communications Commission Equipment Authorization Division 7435 Oakland Mills Road Columbia, MD 21046 USA Date: Sept. 09, 2026 Subject; Modular Transmitter Application Company name: NiceRF Wireless Technology LTD. FCC ID: 2AD66-LORA1281F27-T Dear Sir/Madam, This letter includes the FCC application requirements for Modular Transmitter Approval Request for;- FCC KDB 996369 D01 ‘Module Certification Guide v04r02”; and FCC KDB 996369 D03 “OEM Manual v01r01”. In accordance with 47CFR 15.212 Modular Transmitters and KDB 996369 D01 ‘Module Certification Guide v04r02”, FCC ID: 2AD66-LORA1281F27-T has been examined against the following requirements. Item Requirement per 15.212 and KDB 996369 D01Y/NExplanation from Grantee (Explain why product complies/how it is achieved) 1 The radio elements of the modular transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements. YesThe modular have its own shielding cover. 2 The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with part 15 requirements under conditions of excessive data rates or over-modulation. Yes The modular transmitter has buffered modulation/data inputs. 3 The modular transmitter must have its own power supply regulation. YesThe modular transmitter has its own power supply regulation. 4 The modular transmitter must comply with the antenna and transmission system requirements of §§ 15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). The “professional installation” provision of § 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section. Yes The modular transmitter complies with the antenna requirements. The antenna has a unique connector. 5 The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance with part 15 requirements. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in § 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see § 15.27(a)). The length of these lines shall be the length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified and commercially available Yes The module can be configured independently and meets the requirements FCC 6 7 8 Integ The requ Th e man Any Su m K Ref 2 2 2 2 2 2 2 2 2 2 2 Nam Titl e Sig C Modular A (see § 15.31 The modula permanentl y electronicall The modula rules or ope complete tr a adequate ins any such req be included authorizatio n Radio freque of this part a exposure re 2.1091 , and Application s transmitters confirming c modular tran exposure re Technical i n statement m request. gration Inst e following it uired by the ese items ar nual) to use y requireme mmary of re DB Sect 2.2 List o 2.3 Sum 2.4 Limit 2.5 Trac 2.6 RF e 2.7 Ante 2.8 Labe 2.9 Infor .10 Addi .11 Note .12 How me: GH.

The RF automatic control unit shall have a video bandwidth that is greater than or equal to the DTS bandwidth and shall utilize a fast-responding diode detector. The maximum Average conducted output power may be measured using a wideband RF automatic control unit with a thermocouple detector or equivalent. The RF automatic control unit shall have a video bandwidth that is greater than or equal to the DTS bandwidth and shall utilize a fast-responding diode detector. 4.4.3 Deviation from Standard No deviation. 4.4.4 Test Setup 4.4.5 Test Results Channel Channel Frequency (MHz) Maximum Peak Conducted Output Power (dBm) Limit (dBm) Result CH01 2404 24.45 30.00 Pass CH02 2442 25.85 Pass CH03 2480 26.83 Pass Note: 1.

Page 36 of 53 Report No.: HK2026082500836-E 4.5 Power Spectral Density 4.5.1 Limit For digitally modulated systems, the power spectral density conducted from the intentional radiator to the antenna shall not be greater than 8dBm in any 3 kHz band during any time interval of continuous transmission. 4.5.2 Test Procedure Use this procedure when the maximum peak conducted output power in the fundamental emission is used to demonstrate compliance. Set the RBW = 3 kHz. Set the VBW = 10 KHz. Set the span to 1.5 times the DTS channel bandwidth. Detector = peak. Sweep time = auto couple. Trace mode = max hold. Allow trace to fully stabilize. Use the peak marker function to determine the maximum power level. If measured value exceeds limit, reduce RBW (no less than 3 kHz) and repeat. The resulting peak PSD level no more than 8dBm. During the test, the "duty cycle factor" has already been added to the testing software. 4.5.3 Deviation from Standard No deviation. 4.5.4 Test Setup EUT SPECTRUM ANALYZER Page 37 of 53 Report No.: HK2026082500836-E 4.5.5 Test Results Channel Channel Frequency (MHz) Test Result (dBm/3kHz) CH01 2404 5.65 CH02 2442 6.79 CH03 2480 7.35 Limit : 8dBm/3KHz Test Result PASS CH01 Page 38 of 53 Report No.: HK2026082500836-E CH02 CH03 Page 39 of 53 Report No.: HK2026082500836-E 4.6 6dB Bandwidth 4.6.1 Limit For digital modulation systems, the minimum 6 dB bandwidth shall be at least 500 kHz. 4.6.2 Test Procedure The transmitter output was connected to the spectrum analyzer through an attenuator. The bandwidth of the fundamental frequency was measured by spectrum analyzer with RBW=100 KHz and VBW=300 KHz. The 6dB bandwidth is defined as the total spectrum the power of which is higher than peak power minus 6dB. 1. Set RBW = 100 kHz. 2. Set the video bandwidth (VBW) ≥ 3 RBW. 3. Detector = Peak. 4. Trace mode = max hold. 5. Sweep = auto couple. 6. Allow the trace to stabilize. 7. Measure the maximum width of the emission that is constrained by the frequencies associated with the two outermost amplitude points (upper and lower frequencies) that are attenuated by 6 dB relative to the maximum level measured in the fundamental emission. 4.6.3 Deviation from Standard No deviation. 4.6.4 Test Setup EUT SPECTRUM ANALYZER 4.6.5 Test Result Channel Channel Frequency (MHz) 6dB Bandwidth (MHz) Limit (KHz) Result CH01 2404 1.708 ≥500 Pass CH02 2442 1.716 Pass CH03 2480 1.712 Pass Page 40 of 53 Report No.: HK2026082500836-E CH01 CH02 Page 41 of 53 Report No.: HK2026082500836-E CH03 Page 42 of 53 Report No.: HK2026082500836-E 4.7 Occupied Bandwidth 4.7.1 Test Procedure The occupied bandwidth is the frequency bandwidth such that, below its lower and above its upper frequency limits, the mean powers are each equal to 0.5% of the total mean power of the given emission. The following procedure shall be used for measuring 99% power bandwidth: RBW=1% to 5% of the OBW VBW=approximately 3 X RBW Detector=Peak Trace Mode: Max Hold Use the 99% power bandwidth function of the instrument to measure the Occupied Bandwidth and recorded. 4.7.2 Deviation from Standard No deviation. 4.7.3 Test Setup EUT SPECTRUM ANALYZER 4.7.4 Test Result N/A Page 43 of 53 Report No.: HK2026082500836-E 4.8 Band Edge 4.8.1 Limit In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated device is operating, the RF power that is produced shall be at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of the desired power, based on either an RF conducted or a radiated measurement, provided that the transmitter demonstrates compliance with the peak conducted power limits. If the transmitter complies with the conducted power limits based on the use of root-mean-square averaging over a time interval, as permitted under FCC rules in section 5.8.1, the attenuation required shall be 30 dB instead of 20 dB. 4.8.2 Test Procedure a.
