Abstract
Purpose
Notice / This document has been prepared to assist the IEEE P802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein.
Release / The contributor acknowledges and accepts that this contribution becomes the property of IEEE and may be made publicly available by P802.15.
· This contribution is asking for a modification in the wording of the TG4a PAR to allow the voting membership to trade-off technical parameters during proposal elimination voting and to facilitate proposal elimination based upon voting member sentiment.
· By putting this motion to a vote the committee will have an opportunity to amend the PAR wording. Failure to get approval for this PAR change, at any level in the IEEE, defaults TG4a back to our original PAR wording.
· The CFP (call for proposals) can be made against the original PAR (Doc 15-04-0048-01) while this modification goes through the approval cycle (nothing should slow down or be delayed).
· At issue is the reference to extended range in conjunction with enhanced robustness. This motion proposes eliminating the reference to extended range and keeping the reference to enhanced robustness.
· Current wording has the effect of eliminating proposals based upon a “technicality” instead of “technical merit”.
· Voters whose primary technical interest is more range can express that preference during the down selection voting.
· Voters looking for enhanced robust operation can trade-off proposal features and vote accordingly during the down selection process.
The affected clauses in Doc 15-04-0048-01, and the suggested remedies, are as follows:
Clause 12
[This project will define an alternative PHY clause for a data communication standard with precision ranging, extended range, enhanced robustness and mobility amendment to standard 802.15.4 (18a).]
Clause 13
[To provide an international standard for an ultra low complexity, ultra low cost, ultra low power consumption alternate PHY for 802.15.4 (comparable to the goals for 802.15.4-2003). To satisfy an evolutionary set of industrial and consumer requirements for WPAN communications (18a), the precision ranging capability will be accurate to one meter or better, and the communication range, robustness and mobility improved over 802.15.4-2003. The project will address the requirements to support coexisting (18b) networks of sensors, controllers, logistic and peripheral devices in multiple compliant co-located systems.]
Clause 18a
The CFAs responses collected by study group 802.15.SG4a over the past year indicate an evolutionary market developing for a group of applications that are not fully addressed by 802.15.4. For example, precision ranging, one meter or better, will be required for asset and people sensing and tracking without sacrificing the requirements for low complexity, low cost, and low power consumption. In addition to precision ranging, additional improved communication range, robustness (e.g. multipath resilience, interference immunity) and mobilityinsert>, may are desirable for building and home automation, automated meter reading, industrial, safety, personnel monitoring, security, inventory control, process control and logistic applications.
______
Motion …
It is moved that 802.15.4a modify its’ PAR in the manner shown in this contribution to explicitly remove the references to “extended range” and retain all references to “enhanced robustness”.
