Thx for answer David, but the strange thing it is that o was in a virtual studio here in my country and they use 3 htc vive in same room(open space)with only 2 basestation and works v fine,an d the distance between them was only 1,5-2m.
My problem is i whant to put 6 htc in the same room and i don t know how, it is ok i will use 6 pairs of basestation but i don t whant intrferance.
It is any way to do that?
