Date: 4/21/2024 Federal Communications Commissions Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 RE: Part 15 Subpart E U-NII 6GHz Attestation Letter To whom it may concern: We, Sonos, Inc., attest that this device under FCC ID: SBVRM045 complies with the device protocol requirements and operational restrictions noted in Part 15E of the FCC’s rules for 6GHz bands for Indoor Access Point 6ID. 1. Protocol Statement – The AP uses the IEEE 802.11 beacon signaling to inform the associated client/subordinate device of its permitted maximum power. The IEEE beacon contains a 6GHz Operation Information subfield. The subfield will contain information identifying the AP as a LPI AP and a Maximum Transmit Power Interpretation subfield. 2. 2. We acknowledge the following device restrictions: a. Low-power indoor Access Point. Access Point operating in the 5.925-7.125 GHz band shall be supplied power from a wired connection, has an integrated antenna, is not battery-powered, and does not have a weatherized enclosure. b. The device utilizes bandwidth reduction capability and intentionally reduces the channel bandwidth to allow for continued connection on the set channel during times of network traffic congestion. c. This device's operation will not be allowed on oil platforms, cars, trains, boats, and aircraft, except that operation of this device is permitted in large aircraft while flying above 10,000 feet. d. Indoor access points are prohibited for control of or communications with unmanned aircraft systems, including drones. Sincerely, Andy Bellezza Sr. Compliance Engineer Sonos, Inc.

The device will only associate and connect with a low-power indoor access point or subordinate device and never directly connect to other client devices. b. This device will always initiate transmission under the control of a low-power indoor AP or subordinate except for brief transmissions before joining a network. These short messages will only occur if the client has detected an indoor AP or subordinate operating on a channel. These brief messages will have a time-out mechanism such that if it does not receive a response from an AP it will not continually repeat the request. c. Transmissions will be lower or equal to the power advertised by the indoor low-power access point or subordinate and never above the maximum output power allowed by the FCC grant for equipment class 6XD. d. A contention-based protocol is used to avoid co-channel interference with incumbent devices sharing the band, as demonstrated inside the test report. The CBP mechanism is embedded within the radio and independent of the host. The integration manual supplied with this radio contains all applicable indoor use only and operational restriction warnings to notify the host integrator. e. The device utilizes bandwidth reduction capability and intentionally reduces the channel bandwidth to allow for continued connection on the set channel during times of network traffic congestion. f. The device is prohibited for control of or communications with unmanned aircraft systems, including drones. g. This device's operation will not be allowed on oil platforms, cars, trains, boats, and aircraft, except that operation of this device is permitted in large aircraft while flying above 10,000 feet.
