5.2.2 Smart C Mode 5V power supply, no mode is configured for the module, and the tested current is in the default STA state to be distributed. Average value:68mA, maximum value:167mA The detailed current waveform is shown below 6. Appendix A Document Revision Version No. - Page 23 The input voltage to the module should be nominally 5 VDC, typical value 5VDC and the ambient temperature of the module should not exceed 80℃. Limited module procedures N/A Trace antenna designs N/A Antennas The module of HLK-B32 has one antenna port and the antenna gain as below: 2.4G Wi-Fi: 3.76dBi; 5G Wi-Fi: 4.69dBi.
- Page 24 Label and compliance information When the module is installed in the host device, the FCC ID label must be visible through a window on the final device or it must be visible when an access panel, door or cover is easily re‐moved. If not, a second label must be placed on the outside of the final device that contains the following text: Contains Transmitter Module FCC ID: 2AD56HLK-B32 , the FCC ID can be used only when all FCC ID compliance requirements are met.
- Page 25 shall be placed in the receive mode or idle mode, if possible. If receive mode only is not possible then, the radio shall be passive (preferred) and/or active scanning. In these cases, this would need to enable activity on the communication BUS (i.e., PCIe, SDIO, USB) to ensure the unintentional radiator circuitry is enabled.
