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 baseline proposal, consisting of the following documents, was adopted by TG4k at the November session

  • LECIM DSSS PHY Merger (15-11-795-01)
    • An additional modulation technique in “O-QPSK Modulation Discussion for TG4K” (15-11-804-00)
  • Merged FSK Proposal (15-11-774-01)
  • More MPDU Fragmentation Details (15-11-758-00) & MAC Merge Discussion (15-11-806-03)

TG4k is now drafting text contained in the following documents:

FSK:           15-11-0864
DSSS:        15-11-0863
MAC:          15-11-0882
Annex:        15-12-0044

Weekly conference calls are focused on three groups (FSK, DSSS, MAC) drafting the amendment text and coordinating those efforts, all-in details are sent in the reminders via the TG4k reflector.  The coordination call is being held on Wednesdays at 6:00 a.m. pst.

Future Efforts

 The March session objectives are to review the preliminary draft text as per the Framemaker format and edit as required to support the next milestone of a TG draft review after the May session.
