Nitero is known for its phased-array beamforming millimeter wave chip that can transmit multi-gigabit streams with low latency in room-sized VR environments. The beamforming is key to eliminating line-of-sight requirements associated with traditional high-frequency mm-wave systems used in wired VR headsets.
Up to this point, AMD's efforts in the VR and AR space have revolved around its CPUs inside VR-ready PCs. With this acquisition, AMD is making a pivot toward the wireless VR space, which many consider to be the end-goal for virtual reality headsets.
