TG4t
Timeline
The
first meeting of 802.15 TG4t as a Task Group occurred at the January 2016
Interim Session in Atlanta. In this meeting TG4t developed a Technical
Guidance Document (TGD) in order to give guidance to the proposers on what
the proposals are expected to cover/contain.
At
the March 2016 Plenary Session in Macau TG4t heard proposals in response to
its call for proposals. One joint proposal was submitted, and it was
adopted as the baseline proposal by the TG.
The TG also approved Monique Brown as the Technical Editor.
A
doodle poll was conducted and Wed. (5-6pm Pacific) was selected as the
recurring weekly call day and time. Between the March and May sessions a
baseline draft was developed from the baseline proposal and supporting
documents. Internal TG, WG Tech Editor, and 802.15.4 Tech. Review Team
reviews were conducted in parallel on the baseline draft, prior to the May
2016 Interim Session. Comments from
these reviews were addressed in the conference calls leading up to the May
Interim Session.

the May Interim Session TG4t completed work on the baseline draft and
developed a coexistence assurance document.
