One Kenmore Square | Suite 601 | Boston, MA 02215 | whoop.com WHOOP WM50 Simplified Data Referencing Exhibit WHOOP, Inc. | Confidential Rev 1.0 1 1. Purpose This simplified Data Referencing exhibit is in support of FCC certification of the WHOOP WM50 device under FCC ID 2AJ2X-WM50. WM50 is a hardware variant of the previously certified WS50 device (FCC ID 2AJ2X-WS50). Data Referencing will be applied to BLE-related compliance data from the WS50 certification, including: 1. Conducted average power 2. Conducted peak power 3. Conducted power spectral density (PSD) 4. Conducted 6dB BW 5. Radiated band edge 6. Radiated spurious emissions For SAR, data referencing will not be applied. Instead, applicable testing will be performed and reported independently. Additionally, full conducted spurious emissions and 99% OBW measurements will be performed on the WM50 to demonstrate compliance, and as such, data referencing was not utilized for these tests. A full description of the data referencing exhibit is held as part of the operation description.
