[802SEC] Responses to comments on 802.15.4e draft PAR

EC Colleagues:

Comments were received from one person on the 802.15.4e PAR . There were no 
comments on the 5C. The revised documents are available at  These changes were approved by the 
Working Group by a vote of  55/0/2

The comments received on the 802.15.4e PAR were editorial in nature.  They

5.2 Scope: The scope on the PAR should appear exactly as it will appear in 
the published standard. Consider revising the scope to describe what the 
standard covers rather than what it will cover or what will be considered.
5.4 Purpose: If the standard has a purpose clause, it should appear on the 
PAR exactly as it will appear in the published standard, i.e., the purpose 
of the standard rather than what the purpose of the proposed standard will be.

Response to the above two comments was to recast the tense of the scope and 

5.2 Scope of Proposed Standard: The intent 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 
    *  Low latency: to reduce end to end delivery time such as needed for 
control applications

5.4 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.
