2.5 RNWF11 Module RF Considerations

The overall performance of the system, RF and Wi-Fi are significantly affected by the product design, environment and application. The product designer must ensure system-level shielding (if required) and verify the performance of the product features and applications.

The user must consider the following guidelines for optimal Wi-Fi performance:
  • Position the RNWF11 Module in a noise-free RF environment and keep it far away from high-frequency clock signals and any other sources of RF energy.
  • Do not shield the antenna by any metal objects.
  • The power supply must be clean and noise-free.
  • Ensure that the width of the traces routed to GND, VDD rails are sufficiently large for handling peak TX current consumption.
Note: The RNWF11 Module includes RF shielding on top of the board as a standard feature.
