Wireless Home Digital Interface Consortium has just completed specified video performance with 1080p/60Hz resolution over the 5 GHz frequency. AMIMON is one of the first members to develop this technology along with a group of consumer electronics companies (Hitachi, LG Electronics, Motorola, Samsung, Sharp and Sony).


WHDI technology supports speeds up to 3Gbps in distances up to 30 meters, through walls, support security standards of HDCP 2.0 content and DRM (Digital Rights Management) - which is used to communicate with HDMI in order to protect the point-to-point content.
