Overview
The IEEE 802.15 task group 4b was chartered to create a project for specific enhancements and clarifications
to the IEEE 802.15.4-2003 standard, such as resolving ambiguities,
reducing unnecessary complexity, increasing flexibility in security key
usage, considerations for newly available frequency allocations, and
others.

INFORMATION
CURRENT
STATUS
The IEEE 802.15.4-2006 standard was approved by the
IEEE standards board in June of 2006. The published standard
can be purchased from the IEEE store. TG4b will not have any scheduled
sessions at the September IEEE interim meeting (see meeting details
below)
