Hitachi, Motorola, Samsung, Sharp, Sony and Amimon have joined forces and formed the Wireless High-Def Interface Special Interest Group (WHDI SGI), an initiative to standardize the transmission of wireless high definition content to various devices using Amimon’s promising WHDI technology. WHDI uses the exact unlicensed 5GHz band of spectrum as 802.11a but utilizes its own proprietary protocol.
Using the WHDI standard it is possible to transmit 1080p uncompressed content using two 20MHz channels and 1080i and 720p on a lone 20MHz channel. It can send high definition content ripping through walls up to 30 m, with a latency of only 1 millisecond. However, the members of the newly formed consortium are not bound to integrate the technology in their products.
