Guangzhou Shikun Electronics Co., Ltd Feb. 24, 2022 Attestation Letter for Low Power Indoor Client Module Approval FCCID: 2AR82-SKOWB921A21 We, Guangzhou Shikun Electronics Co., Ltd, attest that this device under FCC ID 2AR82-SKOWB921A21 complies with device protocol requirements and operational restrictions: for indoor client 6XD. a(D. Contention-Based Protocol, as demonstrated in the test report, is permanently embedded in the module and is not host-dependent. The device will only associate and connect with a low-power indoor access b. point or subordinate device and never directly connect to other client devices. This device will always initiate transmission under the control of a low-power c. 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. Transmissions will be lower or equal to the power advertised by the indoor d. low-power access point or subordinate and never above the maximum output power allowed by the FCC grant for equipment class 6XD. Contention-based protocol as demonstrated in the test report is permanently e. embedded in the module and is not host-dependent. Furthermore, we fully understand this device is prohibited for control of or communications with unmanned aircraft systems, including drones. For any questions please contact me at your convenience.
