Wireless In LonghornWireless In Longhorn
Longhorn is a key inflection point for wirelessWi-Fi is now mainstream
Bandwidths and mobility drives productivity, applications
Wireless Cellular deployment growing and moving towards mobile compute platforms
New wireless technologies and standards continue to emerge with new usage models
Ultrawide Band (UWB) , WiMAX
Multiple radio types will be integrated into single system platforms
Longhorn must raise the bar on wireless capabilities, EoU, Manageability, security, and mobility
Extensibility Is KeyExtensibility Is Key
802.11 support in Windows XP was not easily extensible
Led to many independent client solutions
Longhorn Wi-Fi stack addresses thatProvides a uniform user experience
Allows an extensible base for innovation and evolving technology
Increases stability and commonality
Top ChallengesTop Challenges
Battery LifeUser demand for longer run time with multiple radios and feature rich hardware and software environment
