Just a brief overview and breakdown of the differences between wireless Bluetooth dongles and the new Sony Wireless Adapter.
|Form factor||Low profile||Somewhat large dongle|
|Maximum supported controllers||~4||1|
|Audio support||No||Headphones and Microphone|
|Average pooling frequency (under optimum conditions)||650hz||130hz|
|Supports exclusive mode||Yes||
Edit: I now seem to get exclusive mode without issue each time.
|~ 10ft signal strength||~70%||+90%|
|~ 20ft signal strength||~40%||~75%|
|~ 30ft signal strength||unstable||~50% (still very useable even with audio)|
|Transmit power||2.5mw||Unknown but suspect also 2.5mw but with higher gain antenna|
The larger form factor of the Sony Adapter seems to allow for not only a higher gain antenna than those found in common BT adapters, but also houses the hardware needed to decode audio and expose as a WDMA audio device. The refresh rate is slower, but overall latency feels faster and more responsive.
Also worth noting that the Sony Adapter drowned out my wireless BT mouse when in too close of proximity causing the mouse to become un-responsive, the controller when using BT shared the space much more easily.
Its good to have both options available until the exclusive mode is figured out (if possible), but for games that do not require exclusive mode I will likely be sticking with the Sony Adapter due to it feeling slightly less latent despite slower pooling rate.
