May 2004 Straws that Break The contention that WAVE is the Straw that breaks the standard can just as easily be applied to any of the other Amendments as well. 802.3 doc is approximately 2 feet thick when printed. 802.11 wants to be the 802.3 of the Wireless world. Jon Rosdahl, BNJ Consulting

Standalone vs. Amendment May 2004 Standalone vs. Amendment 1. Opinion and emotional ties 2. Perception of inclusion 3. Either way can be and has been argued 4.

Concern over what is or is not important to review and get right Jon Rosdahl, BNJ Consulting
