Address: 46 River Road Hudson, NH 03051 Test Sample: LoRa eSensor Oil Transmitter Brand Name: Senet Part Number: 5848 Serial Number: 219-04-2167 Rev. C Manufactured By: Senet, Inc. Power Requirements: 3.6 VDC via one disposable lithium coin cell battery Frequency Band of Operation: 902.3 MHz to 927.5 MHz Frequencies Tested (Low, Mid and High): 902.3 MHz, 914,9 MHz, 927.5 MHz Antenna Type: ½ Wave Internal 2dBi Equipment Use: Measures Oil Tank Level and Sends Data FCC ID: X94-0005847 Test Specification: FCC Rules and Regulations, Telecommunications, Part 15 Radio Frequency Devices, Subpart C, Intentional Radiators Test Procedure: ANSI C63.4:2003, Methods of Measurement of Radio Noise Emissions from Low Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz 558074 D01, FCC Guidance for Performing Compliance Measurements on Digital Transmission Systems (DTS) Operating Under 15.247, June 5, 2014 DA 00-705, FCC Filing and Measurement Guidelines for Frequency Hopping Spread Spectrum Systems (FHSS) Operating Under 15.247, March 30, 2000 Retlif Testing Laboratories R Report No. R-5909N-2 Page 3 of 85 EUT Description: The LoRa eSensor Oil Transmitter transmits tank data to a receiver. It is used in homes and businesses for propane tank delivery automation. The EUT has two transmission modes for Tank Data Transmissions as described below: Tank Data Transmission – FHSS: The tank information is transmitted over the U.S. 915 MHz ISM band using adaptive data rate LoRa modulation; not exceeding transmit power of 20 dBm over a 125 KHz channel selected randomly from 64 possible channels. Transmissions are scheduled, usually once an hour, with each transmission lasting less than 400 milliseconds. Tank Data Transmission – DTS: An additional operational mode may be configured, in which the device transmits tank information using 500 MHz channels with a transmit power of 20 dBm in the US 915 MHz ISM band using adaptive data rate LoRa modulation. The Senet Oil Sensor Node will use this mode to enable power-efficient and higher bit rate transmissions in locations with very low concentrations of devices using LoRa modulation Tests Performed The test methods performed on the EUT are shown below. Testing was performed in accordance with the applicable FCC requirements for each of the two transmission modes (DTS & FHSS).

The measurement procedures of ANSI C63.4:2003 and ANSI C63.10: 2013 were utilized as specified in FCC Part 15, Subpart C, Section 15.31(a)(3) and FCC Guidance for Performing Compliance Measurements on Digital Transmission Systems, June 5, 2014. 2. All radiated emissions measurements were performed on an Open Area Test Site (OATS), listed with the FCC, in accordance with FCC Section 15.31(d). 3. All measurements were performed at the specified 3 meter test distance as required by FCC Section 15.31(f). 4. The EUT was rotated throughout 360 degrees for all radiated emissions measurements as specified in FCC Section 15.31(f)(5). 5. All readily accessible EUT controls were adjusted in such a manner as to maximize the level of emissions in accordance with FCC Section 15.31(g). 6. Appropriate accessories were attached to all EUT ports during the performance of radiated emissions measurements as required by FCC Section 15.31(i). 7. The EUT operated over the frequency range of 902.3 MHz to 927.5 MHz. Testing was performed with the device operating at 3 frequencies, 1 at the top, 1 in the middle and 1 at the bottom of the range of operation in accordance with FCC Section 15.31(m). 8. The frequency spectrum was investigated from the lowest frequency generated in the device up to the 10 th harmonic of the highest fundamental frequency in accordance with FCC Section 15.33(a)(1). 9. The EUT utilizes an internal ½ wave antenna and does not have an external antenna connector/external antenna and is therefore in compliance with 15.203.
