It seems like Sony is working on introducing Wi-Fi Transceivers to PlayStation controllers. The patent filed by Sony Interactive Entertainment on Feb 4, 2021, describes the inclusion of a Wi-Fi Transceiver to reduce latency on PlayStation.

A computer simulation controller includes both a Bluetooth transceiver and a Wi-Fi transceiver. Player input to the controller generates commands that are sent using both transceivers, such that a receiving apparatus such as a game console or a web server can use the first-arriving one of the two commands to reduce latency.

In simple words, player input will go through both blue-tooth and Wi-Fi transceivers. Whichever signal reaches first takes the input crown. It seems like an odd way to reduce latency since blue-tooth is a direct connection while Wi-Fi signals will have to go through the router, making it a less efficient and slow way to deliver the input signal. Hence, blue-tooth will win the input battle which makes the whole “multipath wireless controller” idea redundant. Unless they are using Wi-Fi Direct.

Moreover, the current design of the Dualsense and DualShock controllers doesn’t have built-in Wi-Fi transceivers (as far as I know). The patent is most likely referring to either a new model for the dualsense controller or simply a technology Sony wants to keep in the bank; so it may never get implemented.

It is a debatable topic since WiFi Direct’s P2P connection is faster than Blue-tooth. It all comes down to how this tech is implemented.
