               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

                       TG4e-PAR
              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.
