Folkways Circle RealmFive.com Lincoln, NE 68504 1 GENERAL 1.1 System Overview The Data Gateway is the link between the edge devices in the Internet of Things (IoT) for agriculture and the cloud data server. The Data Gateway listens for data packets from edge devices and periodically makes a cellular data connection to forward the accumulated edge device packets to a server along with its own packets. The Data Gateway acknowledges packets from edge devices. The Data Gateway also holds downlink packets from the server for edge devices and sends them to the device after the next uplink packet from that device in lieu of an acknowledge. 1.2 Features The Data Gateway includes the following features: • Low power microcontroller • Low power, long range radio for communication with edge devices • Cellular data modem • GPS receiver for device location • Non-volatile memor…

022818 – 11 Request for Confidentiality Date: Subject: Confidentiality Request for: Pursuant to FCC 47 CFR 0.457(d) and 0.459 and IC RSP-100, Section 9.4, the applicant requests that a part of the subject FCC application be held confidential. Type of Confidentiality Requested Exhibit ☐ Short Term ☒ Permanent Block Diagrams ☐ Short Term External Photos ☐ Short Term ☐ Permanent * 3 Internal Photos ☐ Short Term ☒ Permanent Operation Description/Theory of Operation ☐ Short Term ☒ Permanent Schematics ☐ Short Term Test Setup Photos ☐ Short Term ☐ Permanent * 3 User’s Manual RealmFive has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Permanent Confidentiality: The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Short-Term Confidentiality: The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of ___(specify number of days not to exceed 180) 4 ___ days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify ACB in the event information regarding the product or the product is made available to the public before the requested period has expired. ACB will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04-1705. Sincerely, By: __________________________ Nic Johnson, NCEE Labs (Signature/Title 5 ) (Print name) 3 - The asterisked items (*) require further information to be provided to ACB before permanent confidentiality will be extended to these exhibits. Please refer to FCC KDB 726920 and the specific Document link for D01 found at: https://apps.fcc.gov/oetcf/kdb/forms/FTSSearchResultPage.cfm?switch=P&id=41731 and review section II, 3) regarding specific information that must accompany these requests. 4 - Please refer to http://acbcert.com/documents/misc-docs/Memo-Short-Term-Vs-Standard-Confidentiality.pdf for complete details. 5 - Must be signed by applicant contact given for applicant on the FCC site, or by the authorized agent if an appropriate authorized agent letter has been provided.

RF Exposure Evaluation Page 1 of 3 Reference: CFR 47 FCC Part 1.1310 Description: Both transmitters in the device have the possibility of transmitting simultaneously. The worst-case exposure for each transmitter was used to calculate the percentage of the allowable limit that each transmitter contributed. All of the percentages were then added together to verify that at the specified operating distance, they were below the allowable limit. All measurements were peak or RMS power readings taken from test reports from accredited test labs. Antenna gains were taken from the manufacturer’s specifications. Limits: Maximum exposure limits from CFR 47, FCC Part 1.1310: Table 1 - Limits for Maximum Permissible Exposure (MPE) Frequency range (MHz) Electric field strength (V/m) Magnetic field strength (A/m) Power density (mW/cm 2 ) Averaging time (minutes) (A) Limits for Occupational/Controlled Exposure 0.3-3.0 614 1.63 *100 6 3.0-30 1842/f 4.89/f *900/f 2 6 30-300 61.4 0.163 1.0 6 300-1,500 f/300 6 1,500-100,000 5 6 (B) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *100 30 1.34-30 824/f 2.19/f *180/f 2 30 30-300 27.5 0.073 0.2 30 300-1,500 f/1500 30 1,500-100,000 1.0 30 RF Exposure Evaluation Page 2 of 3 FCC RFx Calculations: Transmitter Frequency Antenna Gain Power Power +10% for tolerance Power Density Limit at specified distance % of limit Highest Total FCC ID MHz numerical mW mW mW/cm^2 mW/cm^2 1 902.3 0.91 60.39 66.429 0.0120 0.6015 2.00% 1 2.00% 2A0WY-004B 2A 779 1.54 387.26 425.986 0.1305 0.5193 25.13% 1 25.13% RI7LE866SV1 2A 1710 2.09 181.55 199.705 0.0830 1.0000 8.30% RI7LE866SV1 2B 1720 2.09 238.8 262.68 0.1092 1.0000 10.92% RI7XE866A1NA 2B 704 1.54 212.3 233.53 0.0715 0.4693 15.24% RI7XE866A1NA 2C 1850 2.09 316.0 347.6 0.1445 1.0000 14.45% XPY2AGQN4NNN 2C 824 1.54 316.0 347.6 0.1065 0.5493 19.39% XPY2AGQN4NNN TOTAL 27.13% Table 2 - Calculations according to CFR 47, Part 1.1310, Table 1(B) Specified distance = 20 cm For each radio, the frequency with the lowest limit was used and the highest power of all frequency bands to calculate the worse-case RF exposure. When measurements were performed as EIRP, the antenna gain is listed as 1. In cases where the antenna gain is not listed as 1, the power measurement was performed as conducted and the antenna gain from the manufacturer’s datasheet was used.
