5GHz WLAN Globalization
Where it started
Why it was started
Are we still on track?
What is wrong with this approach?
What we should be doing

Where it Started
This effort began with the 5WLIAG in attempt to simplify wireless networking in the 5GHz bands
Are we still aligned with that group?
TGj will create another standard (amendment)
5WLIAG wants to reduce the number of standards

Why it was Started
IEEE802.11a and HiperLAN2 will not interoperate
Creates uncertainty for users
Which card?
What environment?
An attempt to avoid the 2.4GHz problems

6. What is Wrong With This Approach?
May 2001
What is Wrong With This Approach?
Market confusion
Which one do I need?
Will it interoperate with what I already have?
Certification nightmare
Marketing and Manufacturing logistics nightmares
Richard Kennedy, Compaq Computer Corporation

7. What Should We Be Doing? Simplify, simplify, simplify.
May 2001
What Should We Be Doing?
Simplify, simplify, simplify.
Develop a set of interworking recommended practices
Focus on the partnership project to get to a single standard in the shortest possible time
Watch the market flourish!

The IEEE P GSG will produce as its final output, a set of recommended practices designed to enable HiperLAN2 to achieve a degree of interworking with IEEE a, and a recommendation to ETSI-BRAN to do the same for IEEE a interworking with HiperLAN2.
Recommended practices is defined as rules to be applied when and if compatibility is desired, but are not required
The required degree of interworking is to be determined by the 5GSG.
