The current WiFi standards are kind of at the limit of what they can do, speed wise. The main way IEEE has been able to improve WiFi speeds recently is by basically moving the radio beam around so that it is more focused towards the end user, instead of being non directional. This is kinda the only way they can continue to improve speeds. I think the more important question is does this really need to exist and are the privacy concerns outweighed by people constantly running out of bandwidth, and the answer to that question right now is no, this isn't needed nobody really needs that much speed on wireless and it isn't worth having the real time locations of users for a slight speed increase.
