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

Task Group 4e (TG4e) was created by the IEEE SA’s approval of a PAR to create an amendment to IEEE 802.15.4-2006. The intent of the proposed 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. The PAR for the proposed task group is captured in document (15-07-859-03- 0000). The Task Group officer roles for consideration are: Chair, Vice Chair, Secretary, and Technical Editor. Individuals who wish to be considered for a TG4e officer role should respond with their intent by March 16th 2008 to Pat Kinney, acting chair (pat.kinney@ieee.org) with a copy to Bob Heile (bheile@ieee.org), WG chair. A vote to determine officers will be held at the IEEE 802.15 Plenary Meeting in Orlando, Florida 16-21 March 2008.pat.kinney@ieee.org If you have any questions, please contact me at pat.kinney@ieee.org

7. doc.: IEEE 15-08-0071-00-004e SG4e Jan 2008 Pat Kinney, Kinney Consulting LLC Slide 7 CFA (continued) Background IEEE P802.15.4-MAC amendment Task Group (TG4e) has been chartered to create an amendment to the IEEE802.15.4 MAC. Industrial applications (such as addressed by HART 7 and the ISA100 proposed standards) have used the 802.15.4-2006 standard with modifications to the MAC to suit these environments. Additionally, the proposed Chinese WPAN standard also includes MAC enhancements that cannot be included in TG4c due to its scope. Relevant documents presented in support of the proposed enhancements include: 15-07-0793-01-wng0_case-new-802-15-4-mac-revision.ppt 15-07-0901-00-004e 15-07-0719-01-wng0-issues-with-superframe-structure-ieee-802-15-4-2006 15-07-0935-00-004e 15-08-0024-01-004e 15-08-0030-01-004e 15-08-0025-00-004e This Call for Applications (CFA) solicits data that will help the task group in its efforts. Documents that are already in the IEEE archives can be submitted to this call by providing the reference number. Modified documents should be resubmitted.
