SG4e Purpose
Study group investigating MAC enhancements such as:
Support for Determinism
e.g. TDMA supporting from a few to 10,000s slots
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

TG4e (amended)PAR Scope of Proposed Standard
The intent of this amendment is to enhance and add functionality to the 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

Purpose of Proposed Standard (amended)
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 , , , and
