The IEEE 802.15 Task Group 4c is
defining a PHY amendment which, when published, will be additive to both the
IEEE Std 802.15.4™-2006 standard and the IEEE Std 802.15.4a™-2007 amendment.
This PHY amendment is to address the Chinese regulatory changes which have
opened the 314-316 MHz, 430-434 MHz, and 779-787 MHz bands for Wireless PAN
use within China.
determined that the 779-787 MHz band should be considered for use within the
IEEE 802.15.4 standard. In doing so, an agreement has been reached with the
Chinese WPAN Standards Body to define both an MPSK PHY and a
O-QPSK PHY as co-alternative for use in both standards. The projected
timeline for this amendment to go to RevCom for
final approval is Jan. 2009.

amendment and submitted it for review by members of the 802.15 Working Group in the first
letter ballot which will close shortly before the

interim session TG4c will address the comments from the letter ballot review. The

May session so that the 1st recirculation of the letter ballot can
begin shortly after the close of the
