Overview

The role of IEEE 802.15 Low Energy Critical Infrastructure (LECIM) Task Group 4k is to create a PHY amendment to 802.15.4 to facilitate point to multi-thousands of points communications for critical infrastructure monitoring devices. The amendment addresses the application's user needs of minimal network infrastructure, and enables the collection of scheduled and event data from a large number of non-mains powered end points that are widely dispersed, or are in challenging propagation environments. To facilitate low energy operation necessary for multi-year battery life, the amendment minimizes network maintenance traffic and device wake durations. In addition, the amendment addresses the changing propagation and interference environments.

Current Status

The  draft (d3P802-15-4k_Draft_Standard) was recirculated as Letter Ballot 86. The cummulative vote resulting from LB86 stand at 75% responding, 99% affirmative, 4% abstaining, with 4 comments submitted,  2 of which were  designated as "must be satisfied".  The Ballot Resolution Committee (BRC) voted to reject the comments as 2 were repeats from earlier ballots and 2 were based upon text that had not changed.

The  draft (d3P802-15-4k_Draft_Standard) was released for Sponsor Ballot that ended 13 January 2013 at 11:59 ET.  The Sponsor Ballot results were:

TG4k met at the January session in Vancouver and resolved all non-editorial comments with modified text to be drafted following the session.  Comment resolutions were captured in document 15-13-0032-05.

    Future Efforts

    The next conference call is 30 January at 20:00 PST, call-in details are +1-218-936-4700, participant access code = 802154.

    At the March session, TG4k's objective is to resolve the comments from the Sponsor Ballot recirculation and request conditional approval from the 802 EC to proceed to RevCom .
