November 2002
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.

WiMedia’s Goals
Promote wireless multimedia connectivity.
Leverage standards-based technologies:
IEEE & 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.)
