Test Result Compliant 7.1 Test setup Based on FCC KDB 935210 D05 Indus Booster Basic Meas v01r03: 2019, the system maximum gain and the noise density is measured. Measurements were performed within the EUT’s passband. The noise figure is then calculated by NF = NP – Gain + KTB Noise; where NP is in band noise power per Herz, Gain is measured at the maximum noise frequence with -55 dBm input signal in UL. KTB Noise is 174dB/Hz. The EUT was set to Operation Mode #1. 7.2 Noise Figure Test Results Test Band Gain (dB) kTB (dBm/Hz) Measured Value (dBm/Hz) Noise Figure (dB) 800 PS 91.2 174 -75.8 6.96 700 PS 92.2 174 -75.2 6.62 UHF PS 91.6 174 -75.8 6.58 Prepared by: LabTest Certification Inc.

The Equipment Under Test (EUT) was configured to operate in a continuous transmit mode at the channel producing the highest emission levels. All necessary support equipment was connected and configured to represent typical operation. preliminary scan was performed using a spectrum analyzer with a peak detector. The EUT was rotated through 360°, and the antenna height and polarization were varied to identify the maximum emission levels. Final measurements were performed on all significant emissions identified during the preliminary scan. For each emission: The turntable was rotated to obtain the maximum emission level. The antenna height was adjusted to maximize the received signal. Both antenna polarizations were investigated. Sweep time shall be sufficient to allow accurate measurement of emissions. Radiated spurious emissions shall be measured over the frequency range:9 kHz to the 10th harmonic of the highest fundamental frequency or 40 GHz, whichever is lower, unless otherwise specified by the applicable regulatory rule. The corrected emission levels were compared with the applicable regulatory lim…

Exposure Evaluation RU37™ UHF-700-800 PS Tri-Band Medium Power Remote Unit FCCID: 2BA6ERU373PSABG71A Date: April 7, 2026 Avari Wireless, Inc. 1400 112th Ave SE, Ste 100 Bellevue, WA, USA 98004 http://www.avariwireless.com © Copyright 2026 Avari Wireless. All Rights Reserved Avari Wireless RU37 UHF/700/800 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 38dBm, 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 38 8 7 5012 0.200 37 700 38 8 7 5012 0.267 28 800 38 8 7 5012 0.574 27 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.
