• •Wireless CarPlay uses Bluetooth for initial pairing and later reconnection, but Wi-Fi carries the active CarPlay session.
• •Apple says Wi-Fi handles CarPlay audio, video, control data and even phone-call audio during a wireless session.
• •Users must keep Wi-Fi enabled on the iPhone for wireless CarPlay, but the car does not need to connect to home or public internet Wi-Fi.
• •Apple recommends 5GHz Wi-Fi for less congestion, though some implementations can use 2.4GHz.
• •Adapters marketed for wireless CarPlay generally convert existing wired CarPlay systems rather than adding CarPlay to unsupported vehicles.

The article explains that Wireless CarPlay relies on both Bluetooth and Wi-Fi, with each serving a different role. Bluetooth is used for initial pairing and for helping the car reconnect to the iPhone on later drives. Once the connection is established, Wi-Fi carries the CarPlay interface, audio, control data and phone-call audio. It also notes that wireless adapters typically only convert existing wired CarPlay systems rather than adding CarPlay to unsupported cars.
