2. doc.: Submission, Slide 2 TG4e PAR Scope of Proposed Standard The intention of this amendment is to enhance and add functionality to the 802.15.4-2006 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

3. doc.: Submission, Slide 3 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 802.11, 802.15.1, 802.15.3, and 802.15.4.
