Unfortunately, there aren't viable wireless connectivity alternatives for commercial products other than Wi-Fi for long range and Bluetooth for short range. And both suffer from high (and rising) interference levels in the ISM bands.
- digi_owl 10y agoWifi direct had the potential to be a Bluetooth alternative, but they skipped out on defining "profiles" for common use cases. With Bluetooth you have a list of profiles that define protocols for various use cases. A car head unit is likely using A2DP and AVRCP to handle the streaming and playback controls respectively. It may also implement HFP to allow it to act as a handsfree. Wifi direct do not even, last i checked, have a defined protocol for transferring files between devices. This while Bluetooth supports OBEX, that allows you to either push individual files, or browse the storage of a device remotely. https://en.wikipedia.org/wiki/List_of_Bluetooth_profiles https://en.wikipedia.org/wiki/List_of_Bluetooth_profiles Thats the list of Bluetooth profiles at present.
