Valve Index wireless solution

I was wondering why there isnt a wireless solution for the valve index since there is one for the vive pro . Both got the same resolution per eye so it should be the same bandwith ( 90hz )

The Index is 120/144 Hz, so it’s not so easy and probably won’t be cheap.

But they are looking into that direction:

they dont have to do the 120hz mode , 90hz would be perfectly fine
