Description of Working Group:

  A new generation of wireless technologies has emerged under the generic
  name of Low-Power Wide-Area (LPWA), with a number of common
  characteristics, which make these technologies unique and disruptive for
  Internet of Things applications.

  Those common traits include an optimized radio modulation, a star
  topology, frame sizes in the order of tens of bytes transmitted
  a few times per day at ultra-low speeds and sometimes variable MTUs,
  and, though downstream may be supported, a mostly upstream transmission
  pattern that allows the devices to spend most of their time in low-
  energy deep-sleep mode.

  This enables a range of several kilometers and a long battery lifetime,
  possibly ten years operating on a single coin-cell. This also enables
  simple and scalable deployments with low-cost devices and thin
  infrastructures.

  Those benefits come at a price: the layer 2 frame formats are optimized
  and specific to each individual technology. There is no network layer
  and the application is often hard wired to the layer 2 frame format,
  leading to siloed deployments that must be managed, secured and operated
  individually. Migrating from one LPWA technology to another implies
  rebuilding the whole chain.

  To unleash the full power of LPWA technologies and their ecosystems,
  there is a need to couple them with other ecosystems that will guarantee
  the inter-working by introducing a network layer, and enable common
  components for management and security, as well as shared application
  profiles. The IETF can contribute by providing IPv6 connectivity, and
  propose technologies to secure the operations and manage the devices and
  their gateways.

  The Working Group will focus on enabling IPv6 connectivity over the
  following selection of Low-Power Wide-Area technologies: SIGFOX, LoRa,
  WI-SUN and NB-IOT.

  These technologies present similar characteristics of rare and widely
  unbalanced over-the-air transmissions, with little capability to alter
  the frame formats to accommodate this work, which makes it so that
  existing IETF work (6lo) cannot be trivially applied.

  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.

  The group will produce informational work describing LPWA
  technologies and their needs as well as new standard work to optimize
  IPv6-based communications to the end device

  The group will:

  1. Produce an Informational document describing and relating some
  selected LPWA technologies. This work will document the common
  characteristics and highlight actual needs that the IETF could serve;
  but it is not intended to provide a competitive analysis. It is expected
  that the information contained therein originates from and is reviewed
  by people who work on the respective LPWA technologies.

  2. Produce a Standards Track document to enable the compression and
  fragmentation of a CoAP/UDP/IPv6 packet over LPWA networks. This will be
  achieved through stateful mechanisms, specifically designed for star
  topology and severely constrained links. The work will include the
  definition of generic data models to describe the compression and
  fragmentation contexts. This work may also include to define technology-
  specific adaptations of the generic compression/fragmentation mechanism
  wherever necessary.


Goals and Milestones:
  Done     - Adopt LPWAN specifications as WG item
  Done     - Adopt IP/UDP compression and fragmentation mechanism as a WG item
  Done     - Adopt  CoAP compression mechanism as a WG item
  Done     - Submit LPWAN specification to the IESG for publication as an Informational Document
  Dec 2018 - Submit IP/UDP compression and fragmentation mechanism to the IESG for publication as a Proposed Standard
  Nov 2019 - Submit CoAP compression mechanism to the IESG for publication as a Proposed Standard
