July 2007
15.4 MAC Enhancement Study Group
Motion that passed in the WG closing plenary (27/0/4): That the IEEE WG seek approval from the IEEE 802 EC to start a study group investigating MAC enhancements such as
Support for Determinism
Mixed service and power savings levels in one network (dynamic transmit power control)
Frequency diversity for retransmissions for improved reliability
Low duty cycle operation with beacons for power efficiency
Distributed management of time slots and frequency hopping patterns for fast recovery from regional failures
2ms per hop latency including 1 retransmission
Direct communication between Reduced Functionality Devices in the network
that would allow the IEEE standard to better address the needs of wireless critical applications such as industrial control and alarm systems, waste water plant control and alarm systems, robotics, and last meter telecom services.

Executive Committee Actions c PAR
Four comments were received
All the changes were editorial and did not change the technical content of the document. 
Two were essentially the same and were combined with the two commenters' approval.
All the suggested changes were accepted and reaffirmed by the Working Group (59/0/2).

5.2 Scope of Proposed Standard: This Project will define an amendment to the standard.This amendment shall define alternate PHY and MAC modifications as needed to support the PHY that complies with the applicable Chinese regulations, Radio Management of P. R. of China doc. # or current document, for one or more of the MHz, MHz, and MHz frequency bands.

Changes to the Purpose-
Current
5.4 Purpose of Proposed Standard: It was always the intention for to include support for sub 1 GHz band in China.  The Chinese WPAN is specifying use of the MHz, MHz, and MHz band for LR-WPAN systems and hence sub 1 GHz band can be used for IEEE in China for the first time.
Interference in MHz, MHz, and MHz band is lower than that in 2.4 GHz. Transmission distance in the MHz, MHz, and MHz band is also longer than that in 2.4 GHz.  This makes it appropriate for many applications for which 2.4 GHz is not, due to improved range and reliability.
The amendment to will address operation in one or more of the MHz, MHz, and MHz band defined in the Chinese regulations.
Proposed Changes Based on Comments/Feedback
5.4 Purpose of Proposed Standard: This amendment describes support for sub 1 GHz band in China.  The Chinese WPAN specifies use of the MHz, MHz, and MHz band for LR-WPAN systems and hence these sub 1 GHz bands can now be used for IEEE in China as well.

Changes to the Need--
Current
5.5 Need for the Project: has always embraced operation in 2 bands: 2.4 GHz for global use and sub 1 GHz bands as regionally available.  Currently supports MHz band in the US and the 868 MHz band in Europe.  This amendment will allow for similar operation in the sub 1 GHz band in China for applications benefiting from better propagation characteristics such as automatic metering, industrial control and monitoring. China is a large and important market which makes undertaking a project like this worthwhile.

5.5 Need for the Project: has always embraced operation in 2 bands: 2.4 GHz for global use and sub 1 GHz bands as regionally available.  Currently supports MHz band in the US and the 868 MHz band in Europe.  This amendment will allow for similar operation in the newly defined sub 1 GHz band in China for applications benefiting from better propagation characteristics such as automatic metering, industrial control and monitoring. China is a large and important market which makes undertaking a project like this worthwhile.
Interference in MHz, MHz, and MHz band is lower than that in 2.4 GHz. For a given transmit power and similar propagation conditions, nominal communication range is greater in the MHz, MHz, and MHz bands than in the 2.4 GHz band. This makes it appropriate for many applications for which 2.4 GHz is not, due to improved range and reliability. The amendment to will address operation in one or more of the MHz, MHz, and MHz band defined in the Chinese regulations.
