VLP Atte station Letter Federal Com munications Commission 7435 Oakland Mills Road Columbia MD, 21046 Aug 26, 2024 Re: CFR 47 Part 15 §15.407(d) FCC ID: BCG-A3055 & BCG-A3056 To Whom it may concern: Apple Inc. (“Apple”) certifies that the device(s) listed under FCC ID: BCG-A3055 & BCG-A3056 complies with the following Very Low Power 6VL protocols and restrictions: 1.Device Protocol Attestation Statem ent: a. This device will prioritize spectrum above 6.105 GHz. Channels below 61 08 MHz are disabled. b. This device employs a link-budget-based Transmit Power Control (TPC) mechanism. The TPC mechan ism triggers in an environment wher e received signal strength (RSSI) is above a predetermined threshold. 2.Device Operating Restric t ions: a. This device is prohibited for control of or communication with unmanne d aircraft systems, including drones b. Operation of this device is prohibited on oil platforms and airc raft, except that operation in the 5.925-6.425 GHz b and 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-A3055 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 measured SAR does not deviate more than 10% from the target on the calibration certificate. 2. The return-loss does not deviate more than 20% from the previous measurement and meets the required 20dB minimum return-loss requirement. 3. The measurement of real or imaginary parts of impedance does not deviate more than 5Ω from the previous measurement. The following dipole was checked to pass the above 3 requirements to have 2-year calibration period from the calibration date: Calibration Date Extension Date Certificate Electrical Delay (ns) Certificate SAR Target Head (1g) W/kg @ 20.0 dBm Measured Head SAR (1g) W/kg @ 20.0 dBm Deviation 1g (%) Certificate SAR Target Head (10g) W/kg @ 20.0 dBm Measured Head SAR (10g) W/kg @ 20.0 dBm Deviation 10g (%) Certificate Impedance Head (Ohm) Real Measured Impedance Head (Ohm) Real Difference (Ohm) Real Certificate Impedance Head (Ohm) Imaginary Measured Impedance Head (Ohm) Imaginary Difference (Ohm) Imaginary Certificate Return Loss Head (dB) Measured Return Loss Head (dB) Deviation (%) PASS/FAIL 5/11/2022 5/11/2023 1.153 5.26 4.89 -7.03% 2.45 2.28 -6.94% 54.8 56.1 1.3 8.1 5 3.1 -21 -23.8 -13.20% PASS Calibration Date Extension Date Certificate Electrical Delay (ns) Certificate SAR Target Body (1g) W/kg @ 20.0 …
