    Description of Working Group:

    Broadband Wireless Access Networks address the inadequacies of low
    bandwidth wireless communication for user requirements such as high
    quality data/voice service, wide coverage, etc. The IEEE 802.16 Working
    Group on Broadband Wireless Access Standards develops standards and
    recommended practices to support the development and deployment of
    Broadband Wireless Metropolitan Area Networks.

    A particularity of IEEE 802.16 is that it does not include a rigid
    upper edge MAC service interface. Instead, it provides
    multiple "convergence sublayers (CS)" with the assumption that the
    choice and configuration of the upper edge will be done in accordance
    with the needs of a specific deployment environment (which might be
    DSL replacement, mobile access, 802.11 or CDMA backhaul etc.).

    Specifically, immediately subsequent to network entry, an 802.16
    subscriber station has no capability whatsoever for data (as opposed
    to management) connectivity. Especially, in IP CS case, the criteria
    by which the Base Station (or other headend elements) sets up the
    802.16 MAC connections for data transport are not part of the 802.16
    standard, and depend on the type of data services being offered (e.g.,
    the set up of link layer connections will be different for IPv4 and
    IPv6 services).

    Additionally - as IEEE 802.16 is a point-to-multipoint network - an
    802.16 subscriber station is not capable of multicasting (e.g., for
    neighbor discovery, ARP, IP multicasting services, etc.) or direct
    communication to the other nodes attached to the same Base Station
    within the same subnet (prefix).

    Unlike 3G or xDSL technologies, IEEE 802.16 is not part of an end-to-
    end system definition. Currently, the WiMAX Forum, and, in particular,
    its NWG (Network Working Group) is defining a network architecture
    based on IEEE 802.16.

    The principal objective of the 16ng working group is to specify the
    operation of IPv4 and IPv6 over IEEE 802.16, taking into account the
    IPv4, IPv6 and Ethernet Convergence Sublayers. The working group may
    issue recommendations to IEEE 802.16 and WiMax aiming at improving
    support for IP.

    The scope of this working group is as follows (WG Deliverables);

    - Produce "16ng Problem Statement, Goal and Requirement" to identify
    the specific gaps in the 802.16 MAC for IPv4/IPv6 support, describe
    possible network models (ie. point-to-point, broadcast etc.), and
    provide 16ng related terminology to be used for the base guideline
    while defining solution frameworks. [Informational RFC]

    - Produce "IPv6 over IEEE 802.16 Networks in conjunction with IPv6 CS"
    to define IPv6 operation including the transmission of IPv6 over IEEE
    802.16 link, Neighbor Discovery Protocol, Stateful (DHCPv6) and
    Stateless Address Configuration, Broadcast, Multicast, etc. [Proposed
    Standard RFC]

    - Produce "IPv6 over IEEE 802.16 Networks in conjunction with Ethernet
    CS" to define IPv6 operation including the transmission of IPv6 over
    IEEE 802.16 link, Neighbor Discovery Protocol, Stateful (DHCPv6) and
    Stateless Address Configuration, Broadcast, Multicast, etc. [Proposed
    Standard RFC]

    - Produce "IPv4 over IEEE 802.16 Networks in conjunction with IPv4 CS"
    to define IPv4 operation including the transmission of IPv4 over IEEE
    802.16 links, ARP operation, Stateful Address Configuration (DHCPv4),
    Broadcast, Multicast, etc [Proposed Standard RFC]

    - Produce "IPv4 over IEEE 802.16 Networks in conjunction with Ethernet
    CS" to define IPv4 operation including the transmission of IPv4 over
    IEEE 802.16 links, ARP operation, Stateful Address Configuration
    (DHCPv4), Broadcast, Multicast, etc [Proposed Standard RFC]

    - Produce "IP deployment over IEEE 802.16 Networks" to illustrate the
    IP deployment scenarios including IP CS and Ethernet CS considerations
    over IEEE 802.16 networks based on the WiMAX and WiBro. [Informational
    RFC]

    This working group will take dual stack operation into account in its
    specifications, and reuse existing specifications whenever reasonable
    and possible. The ability to negotiate the used Convergence Sublayer is
    required, as no single mandatory CS can be specified for the clients.
    Work based on the Ethernet CS needs to take into account
    interoperability with existing hosts and other devices that employ
    Ethernet¸ to allow bridging.

    16ng will not initially consider other work items than the ones listed
    above; however, other related work may occur in other WGs, and 16ng
    will participate and help such efforts.
