AT-41511-BLKG datasheet by Avago Technologies

AT-41511-BLKG Frequently Asked Questions (FAQs)

• What is the recommended antenna design for optimal performance?
  A quarter-wavelength monopole antenna or a PCB antenna with a 50-ohm impedance is recommended for optimal performance. The datasheet provides guidelines for antenna design, but it's essential to consult with a qualified RF engineer for custom designs.
• How do I implement secure boot and secure firmware updates?
  The AT-41511-BLKG supports secure boot and firmware updates using Broadcom's WICED Security Development Kit (SDK). Consult the WICED SDK documentation and Broadcom's security guidelines for implementation details.
• What is the maximum transmit power, and how do I adjust it?
  The maximum transmit power is +5 dBm. You can adjust the transmit power using the WICED SDK's API, which allows you to set the power level in increments of 1 dBm. However, be aware of regulatory restrictions on transmit power in your region.
• How do I implement coexistence with other wireless technologies (e.g., Wi-Fi, Zigbee) in the same device?
  Use the WICED SDK's coexistence API to manage concurrent wireless technologies. This API provides mechanisms for dynamic frequency selection, transmit power control, and packet prioritization to minimize interference.
• What is the recommended power supply decoupling and filtering for the module?
  Use a 10 uF capacitor in parallel with a 100 nF capacitor for power supply decoupling. Additionally, add a Pi-filter (e.g., 10 uH inductor, 10 uF capacitor, and 10 uF capacitor) to filter out noise and ensure stable operation.
