9.2 RF Considerations
Note that overall system, RF and WiFi performance is significantly affected by the product design,
environment and the application. It is the responsibility of the product designer to ensure proper
system level shielding (if required) and to verify performance and fitness for the given product
features and applications.
The WiFi performance will be affected by the RF environment surrounding the CX module. Please
ensure that the CX module is positioned in a “quiet” RF environment, as far away as possible from
high frequency clock signals and any other sources of RF energy. Also, make sure the antenna is not
shielded by any metal objects, for example loudspeakers or other metal parts. Please make sure that
the power supplies, in particular the +1.9V supply, are quiet and free from noise.
BridgeCo recommends that systems implementing AirPlay should use a module configuration that
includes on-module shielding, as well as paying particular attention to system configuration and
shielding.
