Exposure Evaluation RU40™ UHF PS Single-Band High Power Remote Unit FCCID: 2BA6ERU401PSH21A Date: September 4, 2025 Avari Wireless, Inc. 1400 112th Ave SE, Ste 100 Bellevue, WA, USA 98004 http://www.avariwireless.com © Copyright 2025 Avari Wireless. All Rights Reserved Avari Wireless RU40 UHF Exposure Evaluation Page 2 of 2 RF Exposure Evaluation According to FCC Part 1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. More information on evaluating compli ance with these limits can be found in the FCC's OST/OET Bull etin Number 65, “Evaluating Compliance with FCC-Specified Guideli nes for Human Exposure to Radiofrequency Radiation”. The maximum power density limit allowed for uncontrolled exposures for an average time of 30 minutes is frequency and output power dependent. Although the equipment under test is capable of producing a composite output power of up to 45dBm, the overall ERP can’t exceed 37dBm. Cable distribution loss and antenna gain needs to be taken into account as part of the design and installation in order not to exceed the maximum 37dBm ERP limit. The table below illustrates the different operating scenarios with maximum allowed output power of 37dBm at the antenna representing worst case scenarios from a RF Exposure point of view. Freq Band (MHz) Conducted Output Power (dBm) Min. Cable Loss (dB) Max Antenna Gain (dBi) Max EIRP (mW) Power Density Limit Allowed (mW/cm²) Safe Distance (cm) 450 45 15 7 5012 0.300 37 RF Exposure Evaluation Distance Calculation 푑푑=√ (퐸퐸퐸퐸퐸퐸퐸퐸/4휋휋휋휋) Where: d = Distance to the center of radiation of the antenna (cm) for the allowable Power Density S = All owable Power Density Limit (mW/cm 2 ) EIRP = Equivalent isotopically radiated power (mW) = 10 [TX Power (dBm) + Ant Gain (dBi)/10] If the antenna will be positioned closer to end users than the required safe distance, then the installer must calculate the power back off required for a given installation using the formulas provided.

Based on FCC KDB 935210 D05 Indus Booster Basic Meas v01r03: 2019, the two tone was located on either side of the maximum gain frequence in the passing band, and separated with the available spacing, which is 12.5kHz. Measurements were performed with modulated tone at identical input amplitude which produced integrated maximum rated output power. The EUT was set to Operation Mode #1 with configuration Mode #1.
