2. TG4e PAR Scope of Proposed Standard
October 19
TG4e PAR Scope of Proposed Standard
The intention of this amendment is to enhance and add functionality to the MAC to a) better support the industrial markets and b) permit compatibility with modifications being proposed within the Chinese WPAN.
Specifically, the MAC enhancements are limited to:
TDMA: to provide a) determinism, b) enhanced utilization of bandwidth
Channel Hopping: to provide additional robustness in high interfering environments and enhance coexistence with other wireless networks
GTS: to increase its flexibility such as a) supporting peer to peer, b) the length of the slot, and c) number of slots
CSMA: to improve throughput and reduce energy consumption
Security: to add support for additional options such as asymmetrical keys
Low latency: to reduce end to end delivery time such as needed for control applications

Purpose of Proposed Standard
This functionality facilitates Industrial applications (such as addressed by HART 7 and the ISA100 proposed standards), and those enhancements defined by the proposed Chinese WPAN standard that aren't included in TG4c. This amendment addresses coexistence with wireless protocols such as , , , and

Meeting Goals
Hear presentations on proposed application spaces to be addressed with e amendment
Discussion and group affirmation on specific application spaces targeted by TG4e
Hear modifications to e proposal presentations
Association of proposals to application spaces
Selection of proposals to form baseline draft for specific application spaces

5. Proceeding from Proposals to Draft
Define Application spaces:
Define MAC behaviors that must be added/enhanced per application space
Define those application spaces that TG4e will address
Define MAC behaviors that proposals will add/enhance
Review proposals based upon Application Space/MAC behavior
TG selection of MAC behavior proposals or definition of criteria used for MAC behavior selection
Draft changes
