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

A Technical Guidance Document (15-11-0359-04) and a Call for Proposals (15-11-0147-02) were drafted and approved at the May Interim session. These documents are necessary for the task group to define a baseline for the development of the draft amendment.

The September session acomplishments included hearing all final proposals and included a panel discussion across all proposals.

The final proposals were:
