Why a New Wireless Standard? No previous wireless standard has been
optimized for multimedia.
WiFi, Bluetooth and others include core (MAC & PHY) optimizations for their respective target markets.
Multimedia needs to have (spec. & implementation): advanced QoS low cost (low complexity) simplicity of use long battery life adequate data rate and spatial capacity a scalable security platform etc.
Leverage standards-based technologies: IEEE 802.15.3 & 15.3a will be the starting point. Adopt evolving wireless multimedia technologies as
they emerge.
Establish a certification and logo program.
Support development of any necessary higher layer protocols and software specifications.
Liaison with key organizations (IEEE, Bluetooth, WECA, Cable Labs, DVB WIN, 1394TA, USB Forum, CPTWG and others.)

WiMedia Main Characteristics (I) Complete system solution for multimedia connectivity
A/V transport and control, imaging & service discovery profiles.
High Data Rate WPAN Currently up to 55 Mbps, up to 50m range 480 Mbps in the future
High Spatial Capacity The aggregate data rate of any wireless technology in a finite
space is constrained. WiMedia is designed to achieve the demanding spatial capacity needs of the MM apps.
