The 802.11g standard appears likely to be ratified during the meeting of the IEEE Standards Board Review Committee tomorrow.
The standard has passed several regulatory hurdles in the past week, in which it has been approved by the IEEE Revision Subcommittee and the 802 Executive Committee. The 802.11 Working Group delivered the draft standard (version 8.2) at the end of April.
Apple employs 802.11g in its AirPort Extreme products. Some companies have already distributed software updates for their 802.11g products, based on that draft standard. Apple released its AirPort 3.0.4 update on April 24.
