Overview

The end work product of the IEEE 802.15 High Rate Task Group 4t is the generation of an amendment to 802.15.4 defining a physical layer capable of supporting 2 Mb/s data rates, utilizing the 2400 - 2483.5 MHz band, having backwards-compatibility to, and the same occupied bandwidth as, the present 2450 MHz O-QPSK physical layer, and capable of simple implementation.

Current Status

TG4t is awaiting the approval by RevCom, which is on the agenda for their January 2017 call.

Future Efforts

Upon approval by RevCom and SA the draft will be scheduled for (publication) editing.

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.

At the May Interim Session TG4t completed work on the baseline draft and developed a coexistence assurance document.  At the closing WG Plenary the WG approved the start of the Letter Ballot for TG4t.

The 1st Letter Ballot (LB 123), of “P802.15.4t Draft Standard for Local and Metropolitan Area Networks - Part 15.4: Low-Rate Wireless Personal Area Networks (WPANs) Amendment for a Higher Rate Physical (PHY) Layer” (D01) closed on June 23rd.

The ballot passed and 16 comments were submitted. Comment resolution began prior to the July 2016 Sessions, continuing and concluding at the July 2016 sessions. The 802.15 WG approved the comment resolution database and for the editor to make the changes to the draft as instructed in the comment resolution database. Conditional Approval was sought and given by the EC to proceed to Sponsor Ballot on July 29th.

The 1st Recirculation Letter Ballot (LB 125), of “P802.15.4t Draft Standard for Local and Metropolitan Area Networks - Part 15.4: Low-Rate Wireless Personal Area Networks (WPANs) Amendment for a Higher Rate Physical (PHY) Layer” (D02) closed on August 14th.

The ballot passed and 1 comment was submitted. The 802.15 TG4t BRC resolved the 1 comment and approved the comment resolution database and for the editor to make the changes to the draft as instructed in the comment resolution database.

The 2nd Recirculation Letter Ballot (LB 128), of “P802.15.4t Draft Standard for Local and Metropolitan Area Networks - Part 15.4: Low-Rate Wireless Personal Area Networks (WPANs) Amendment for a Higher Rate Physical (PHY) Layer” (D03) closed on September 4th.

The ballot passed and 3 comment were submitted – all editorial (which were withdrawn after the ballot closed). Having achieved 100% Affirmation, the 802.15 TG4t BRC proceeded to initiate the Sponsor Ballot.

The 1st Sponsor Ballot, of “P802.15.4t Draft Standard for Local and Metropolitan Area Networks - Part 15.4: Low-Rate Wireless Personal Area Networks (WPANs) Amendment for a Higher Rate Physical (PHY) Layer” (D04) closed on October 8th. The ballot passed with 98% Approval and 25 comments being submitted.

The 1st Recirculation Sponsor Ballot, of “P802.15.4t  Draft Standard for Local and Metropolitan Area Networks - Part 15.4: Low-Rate Wireless Personal Area Networks (WPANs) Amendment for a Higher Rate Physical (PHY) Layer” (D05) closed on November 7th. The ballot passed with 98% Approval and 5 comments being submitted.

The 2nd Recirculation Sponsor Ballot, of “P802.15.4t Draft Standard for Local and Metropolitan Area Networks - Part 15.4: Low-Rate Wireless Personal Area Networks (WPANs) Amendment for a Higher Rate Physical (PHY) Layer” (D06) closed on November 27th. The ballot passed with 100% Approval and 1 comment being submitted.

Approval was given by the TG, WG and EC at the November Plenary to Submit the Draft to RevCom.
