IEEE 802.15.4a is completed!

IEEE 802.15.4a passes with 97% approval.

IEEE 802.15.4a has passed the recirculation sponsor ballot with 97% approval and no new technical comments.The two and a half year schedule, drawn up when the task group was formed in 2004 suffered no slippage.

802.15.4a is the new alternative PHY for the 802.15.4 standard. It adds location awareness, low power and higher data rates to the standard which is the PHY and MAC specification for Zigbee devices. The standard was offcially ratified in March 2007.

 

IEEE 802.15.3a is no more...

Motion to remove the high rate ultra wideband project from the IEEE gains 95% approval.

At a subdued  IEEE UWB standards meeting held in January 2006 in Hawaii, a motion to recommend removing project authorisation for 802.15.3a received 95% approval by the task group.

Both the DS-UWB and the MB-OFDM proponents voted in favour of the motion. This was the first time both camps have agreed on something since the task group became polarised in September 2003.

The DS-UWB proposal was authored by Decawave, Freescale and NICT

 

IEEE 802.15.4a passes letter ballot at first attempt

The letter ballot for 802.15.4a, the new alternative PHY for 802.15.4 (Zigbee), got just over the required 75% approval when the ballot closed on Sunday, 15th January 2006.

The task group then spent the meeting time in Hawaii addressing the comments received from voters. Although 75% is the required hurdle, the aim of the task group is to raise this into the late 80% approval rating before submitting the draft as a new IEEE standard.
