Deterministic Networking is an attempt to mostly eliminate packet loss for a
	committed bandwidth with a guaranteed a worst case end-to-end latency, even
	when co-existing with best-effort traffic in a shared network. It is getting
	traction in various industries including manufacturing,	professional A/V,
	cellular radio, and others, making possible many cost and performance
	optimizations. 
	
	This innovation is enabled by recent developments in technologies including
	IEEE 802.1 TSN (for Ethernet LANs) and IETF DetNet (for wired IP networks).
 	Predictable and Available Wireless (PAW) services extend DetNet services to
	approach end-to-end deterministic performances in a network with wireless
	segments, possibly combined with wired segments. 
	
	IP networks become more deterministic when the effects of statistical
	multiplexing (jitter and collision loss) are eliminated. This requires a 
	tight control of the physical resources to maintain the amount of traffic
	within the physical capabilities of the underlying technology, e.g., by the 
	use of time-shared resources (bandwidth and buffers) per circuit, and/or by
	shaping and/or scheduling the packets at every hop.
 
	Wireless networks operate on a shared medium, and thus transmissions cannot
	be fully deterministic due to uncontrolled interferences, including the
	self-induced multipath fading. However, scheduling of transmissions can
	alleviate those effects	by leveraging diversity in the spatial, time and
	frequency domains, providing a more predictable and available service.
	
	The wireless and wired media are fundamentally different at the physical 
	level, and while the generic Problem Statement for DetNet applies to the 
	wired as well as the wireless medium, the methods to achieve PAW necessarily
	differ from those used to support time-sensitive networking over wires. 
	
	The development of PAW technologies today has lagging behind wired systems
	both at the IEEE and the IETF. But recent efforts at the IEEE and 3GPP 
	indicate that wireless is finally catching up at the lower layer and that 
	it is now possible for the IETF to extend deterministic networking to 
	wireless segments through the use of scheduling of wireless transmissions.

	PAW will centralize efforts that inherit from DetNet and 6TiSCH, with a
	primary	focus on scheduled wireless operations. The Working Group will
	leverage cross-participation with the associated set of stakeholders to
	ensure that the work taking place corresponds to real demands and that the
	proposed solutions are indeed applicable. It will focus on enabling PAW
	connectivity over the following	selection of deterministic wireless
	technologies: IEEE Std. 802.15.4 timeslotted channel hopping (TSCH), 3GPP 5G
	ultra-reliable low latency communications (URLLC), IEEE 802.11 extreme high
	throughput (EHT) and the L-band Digital Aeronautical Communications System
	(LDACS).

    The group will:

        1) Produce informational work describing deterministic wireless
           use cases, in continuation to the DetNet Use Cases document
		
         2) Produce informational work describing the technologies that the
            group will cover (e.g. 5G, TSCH, RTA and LDACS) 

        3) Produce a Standards Track document to define the generic data models
           to install a PAW flow along a track providing packet replication, 
           elimination and ordering functions with spatial, frequency and time
           diversity in a scheduled FD/TDMA wireless network.

        4) Produce a Standards Track document to enable operations, 
           administration and maintenance (OAM) inside a PAW network, providing
           packet loss evaluation and automated adaptation to enable trade-offs
           between resilience and energy consumption.
