VLP Attestation Letter Federal Communications Commission 7435 Oakland Mills Road Columbia MD, 21046 Aug 26, 2024 Re: CFR 47 Part 15 §15.407(d) FCC ID: BCG-A3050 & BCG-A3053 To Whom it may concern: Apple Inc. (“Apple”) certifies that the device(s) listed under FCC ID: BCG-A3050 & BCG-A3053 complies with the following Very Low Power 6VL protocols and restrictions: 1. Device Protocol Attestation Statement: a. This device will prioritize spectrum above 6.105 GHz. Channels below 6108 MHz are disabled. b. This device employs a link-budget-based Transmit Power Control (TPC) mechanism. The TPC mechanism triggers in an environment where received signal strength (RSSI) is above a predetermined threshold. 2. Device Operating Restrictions: a. This device is prohibited for control of or communication with unmanned aircraft systems, including drones b. Operation of this device is prohibited on oil platforms and aircraft, except that operation in the 5.925-6.425 GHz band is permitted in large aircraft flying above 10,000 feet.

CONFIDENTIALITY REQUEST Federal Communications Commission 7435 Oakland Mills Road Columbia MD 21046 Subject: Request for Confidentiality FCC ID: BCG-A3050 To Whom It May Concern: Pursuant to the provisions of Sections 0.457(d) and 0.459 of the Commission’s rules (47 CFR §§ 0.457, 0.459), Apple Inc. hereby requests confidential treatment for documents filed with the Commission in connection with the application for equipment authorization referenced above. Apple Inc. requests that the Commission withholds the following documents from public viewing indefinitely: Long Term Confidentiality Schematic Diagram BOM Block Diagram Theory of Operation Antenna Specification These documents reveal detailed technical and design information that is protected by Apple Inc. as confidential and proprietary trade secrets. This information has been disclosed to those required to maintain its confidentiality, and is not customarily disclosed to the public even after commercial release of a device. As a result, disclosure of this information by the Commission would harm Apple Inc. by giving competitors an unfair advantage even after commercial release of the device. In addition to the above mentioned documents, pursuant to Public Notice DA 04-1705 of the Commission’s policy, in order to comply with the marketing regulations in 47 CFR §2.803 and the importation rules in 47 CFR §2.1204, while ensuring that business sensitive information remains confidential until the actual marketing of newly authorized devices, Apple Inc. requests that the Commission withholds the following documents from public viewing for one hundred eighty days after the date the grant of equipment authorization is issued: Short Term Confidentiality External Photographs Internal Photographs Test Setup Photographs User Manual These documents reveal technical and design information that has not been publicly disclosed in marketing materials and is protected by Apple Inc. as confidential and proprietary trade secrets. This information has been disclosed to those required to maintain its confidentiality, and is not customarily disclosed publicly prior to the commercial release of the device. As a result, disclosure of this information by the Commission prior to commercial release would harm Apple Inc. by giving competitors an unfair market advantage. Apple Inc. believes the period of confidentiality requested is necessary to protect the information until the commercial release of a device. Sincerely, Abhishek Rala Apple Inc.

The tissue was placed in a nonmetallic container. Trapped air bubbles beneath the flange were minimized by placing the probe at a slight angle. 3) The complex admittance with respect to the probe aperture was measured. 4) The complex relative permittivity ε ’ can be calculated from the below equation (Pournaropoulos and Misra): where Y is the admittance of the probe in contact with the sample, the primed and unprimed coordinates refer to source and observation points, respectively, ,  is the angular frequency, and . Figure D-1 Note: Liquid recipes are proprietary SPEAG. Since the composition is approximate to the actual liquids utilized, the manufacturer tissue-equivalent liquid data sheets are provided below.

Table E-1 SAR System Validation Summary NOTE: While the probes have been calibrated for both CW and modulated signals, all measurements were performed using communication systems calibrated for CW signals only. Modulations in the table above represent test configurations for which the measurement system has been validated per FCC KDB Publication 865664 D01v01r04 for scenarios when CW probe calibrations are used with other signal types. SAR systems were validated for modulated signals with a periodic duty cycle, such as GMSK, or with a high peak to average ratio (>5 dB), such as OFDM according to FCC KDB Publication 865664 D01v01r04 SENSITIVITY PROBE LINEARITY PROBE ISOTROPY MOD.
