WiMAX EcosystemThe WiMAX ecosystem has made great progress in the
development and deployment of WiMAX solutions, and
momentum is increasing with:
• Ratification of IEEE 802.16e-2005 in December 2005.
• Real WiMAX deployments around the globe: 175 today
and growing.
• A strong and rapidly growing WiMAX ecosystem that is
expected to offer choice and lower costs to consumers:
The WiMAX Forum currently counts over 370 member
companies.
• Consensus on 2.3 GHz, 2.5 GHz, and 3.5 GHz spectrum
bands for WiMAX network deployment.
In order to accelerate WiMAX deployment and adoption,
ecosystem alignment around an end-to-end system
implementation is critical. With such alignment, we expect
interoperability, economies of scale, and optimized system
costs and performance.
Intel® Centrino® Mobile Technology Reference GuideThis guide is intended to help achieve ecosystem alignment
by giving service providers and the WiMAX industry ecosystem
a view into Intel's currently planned future mobile platforms. It
includes an overview of usage models and laptop platform
capabilities, a description of the relationship between platform
capabilities and key elements of the mobile WiMAX network,
and most importantly, a reference model for service providers
and the ecosystem based on Intel's planned mobile platform
capabilities.
The “Intel Centrino Mobile Technology Reference Guide for
WiMAX Networks” provides a unique look at what is required
to support consistent access to WiMAX networks by clients
coming from and moving to any network. Intel's goal is to
establish a common standards-based approach to promote
interoperability.
The audience and intended usage for this guide is:
• WiMAX operators and service providers. To plan new
network deployments and upgrade existing networks, and in
so doing, helping to ensure networks are Intel Centrino mobile
technology-ready to provide easy access, security features,
and advanced functionality to their WiMAX users.
• WiMAX equipment vendors. To develop infrastructure
solutions interoperable with WiMAX-enabled Intel Centrino
mobile technology-enabled laptops.
• Application and service developers. To develop
innovative applications and services using the features
and capabilities supported in WiMAX-enabled Intel Centrino
mobile technology-enabled laptops.
The ultimate goal is for the WiMAX industry to join together
to promote the adoption of open, Internet Protocol (IP) based
standards for authentication, authorization, accounting, Quality
of Service (QoS), security, mobility/roaming, and low-power
operation to help enable consistent, reliable network perform-
ance for access devices such as laptops, ultra-mobile PCs,
and more.

Guide OverviewThis section provides a brief overview of some of the topics to
be addressed in the detailed technical white paper expected
to be published later this year. The intention of this guide is to
provide some early information to help ensure WiMAX network
interoperability with WiMAX-enabled Intel Centrino mobile
technology-enabled laptops.
Intel fully supports the WiMAX Forum and has taken a leader-
ship position in its promotion and development. In developing
the “Intel Centrino Mobile Technology Reference Guide for
WiMAX Networks,” Intel paid special attention to developing
reference models that conform to the work the WiMAX Forum's
Technical, Certification, and Network Working Groups are doing,
based on requirements defined by the Service Provider Working
Group, specifically:
• Specifications for infrastructure and client interoperability
• Specifications and process for client and base station
certification
• Specifications for end-to-end network architecture and
protocols
In this manner, Intel is supporting the broad WiMAX industry
defined system profiles, network specifications, and confor-
mance test specifications.
End-to-End Reference Model for Intel Centrino MobileTechnology Interoperability
The reference model for Intel Centrino mobile technology inter-
operability is based on the laptop communications architecture
discussed in the previous section, combined with the WiMAX
network reference model developed within the WiMAX Forum.
Relationships and interoperability requirements between
functional entities will be specified in the forthcoming white
paper version of this guide.

System Profile
The WiMAX Forum mobile system profile defines the required
and optional air interface (physical and medium access layers)
features supported for interoperability between the WiMAX BS
and MS equipment, based on the IEEE 802.16e-2005 and ETSI
HiperMAN standards needed for compliance to WiMAX Forum
certification. WiMAX-enabled Intel Centrino mobile technology-
enabled laptops as currently planned will comply with all
WiMAX Forum mobile requirements.
During vendor development and self-test, Intel plans to priori-
tize interoperability testing with BS solutions supporting MIMO
and AAS/BF due primarily to the improved coverage, capacity,
and user throughput performance of systems supporting these
technologies.
Ethernet CS (defined as an optional feature for WiMAX BS
and MS equipment in the system profile) support is expected
primarily in CPE/RG solutions targeted for fixed service offer-
ings. While WiMAX-enabled Intel Centrino mobile technology-
enabled laptops will co-exist on a BS supporting Ethernet CS.

Certification Profiles
The certification profiles define the frequency band, duplexing
scheme, and channel bandwidth supported for interoperability
of WiMAX BS and MS equipment. Of the candidate WiMAX
Forum mobile certification profiles, WiMAX-enabled Intel
Centrino mobile technology-enabled laptops targeting
regional/global roaming are planned to prioritize support for
certification profiles based on the 5 MHz, 8.75 MHz (required
for South Korea), and 10 MHz channel bandwidths.
Access Service Network Functionality
The ASN represents the point of entry for WiMAX MS equip-
ment into a WiMAX network, and as such, must support a
complete set of network functions required to provide radio
access to the MS. The ASN provides the following mandatory
functions:
• WiMAX Layer-2 (L2) connectivity with WiMAX MS
• Transfer of AAA messages to the WiMAX subscriber’s home
network service provider (H-NSP) for authentication, authori-
zation and session accounting for subscriber sessions
• Network discovery and selection of an appropriate NSP from
which the subscriber accesses WiMAX services
• Relay functionality for establishing Layer-3 (L3) connectivity
with a WiMAX MS (for example, IP address allocation)
• Radio resource management
• ASN-CSN tunneling
In addition to the previous mandatory functions, for a portable
and mobile environment, an ASN shall support the following
functions:
• ASN anchored mobility
• CSN anchored mobility
• Paging and location management
The ASN is comprised of network elements such as one or
more base stations, and one or more ASN gateways, and
may be shared by more than one connectivity service
network (CSN).
Handover
The WiMAX Forum Networking Working Group (NWG) WiMAX
network specifications identify the following types of mobility
within a WiMAX Network:
• ASN anchored mobility. Mobility of MS between two BSs
(serving and target BS) within or across an ASN boundary.
• CSN anchored mobility. Mobility resulting in change of
point of attachment IP address for the MS when anchored to
the same CSN.

Figure 6. ASN Functionality Reference model for Intel® Centrino® mobile technology interoperability highlighting some of the elements related to handover and power management.
The procedures related to CSN anchored mobility are depen-
dent on whether network access is based on IPv4 or IPv6. In
the case of IPv4, handover can be performed based on Proxy
Mobile IP (PMIPv4) or Client Mobile IP (CMIPv4). The PMIPv4
procedure is entirely done in the network and the MS is
agnostic to the related procedures. For IPv6, CSN anchored
mobility is performed based on CMIPv6.
Power Management
Power management for MS equipment is vital to helping
ensure optimal battery life performance. Platform power man-
agement refers to the efficient allocation of sleep and idle
modes to an MS in order to help maximize battery life while
minimizing disruption of communication flows between an MS
and the WiMAX network.
Idle mode capabilities defined within the IEEE 802.16e-2005
standard allow for MS equipment to power down in order to
optimize battery life. Paging refers to procedures used by the
WiMAX network to seek an MS in idle mode within the cover-
age area of a predefined BS or set of BSs (identified by a
paging group). Coordination of paging procedures is handled by
the paging control/agent functions residing in the ASN GW.
Paging in WiMAX networks can be based on either unicast or
multicast addressing. WiMAX-enabled Intel Centrino mobile
technology will support unicast paging.
Service Provisioning, Authentication, and SecurityIn order for a WiMAX MS to securely enter a WiMAX network,
robust schemes and protocols for various network entry
scenarios must be supported, as well as strong protection
of user data traffic and control messaging.
Service Provisioning
In a WiMAX network, a full network discovery and selection
procedure includes four steps:
1. NAP discovery
2. NSP access discovery
3. NSP enumeration and selection
4. ASN attachment based on NSP selection
The procedure is applicable to the first time use, initial network
entry, network re-entry, or when an MS transitions across NAP
coverage areas.
In the case of first time use, the authenticity of the MS must
be established in order to allow for provisioning of service and
access to Internet services. WiMAX-enabled Intel Centrino
mobile technology-enabled laptops are expected to support
either over-the-air (OTA) or smart-card-based service
provisioning.
Start Guide Intel® Centrino® Mobile Technology Reference Guide for WiMAX Networks
10
In the case of OTA provisioning, credentials (for example X.509
certificates) indicating that the WiMAX Forum has certified
the MS will be stored in the MS during manufacturing.
PKMv2/EAP-TLS is being considered for establishing
credentials during service provisioning.
USIM-based service provisioning is expected to be supported
on UICC/smart-card-enabled laptops, utilizing PKMv2/EAP-AKA
as the mechanism for authentication.
Authentication
Once service has been provisioned, authentication is performed
on initial network entry, network re-entry, or transitions across
NAP coverage areas. Authentication may be based either on
user, or on both user and device. Double EAP authentication
will be supported for user and device authentication.
Non-smart-card-based authentication will utilize PKMv2/
EAP-TTLS (username/password) as the preferred mechanism
for user authentication, and may utilize PKMv2/EAP-TLS
(certificate) as the mechanism for device authentication.

Smart-card-based authentication is expected to utilize
PKMv2/EAP-AKA (user and device credentials stored in
smart card).
Security
Provisions for helping to ensure the integrity of user data traf-
fic and control messaging is essential for wide scale system
deployment. Security and cryptographic suite support specified
in the WiMAX Forum Mobile System Profile represents the
latest in state of the art security.
Encryption of user data traffic is expected to be based on AES
in CCM mode. Management message integrity protection is
expected to be based on cipher-based MAC (CMAC).
Roaming
Roaming is the capability enabling a wireless subscriber to
obtain network services using a “visited” operator’s network
using credentials provided by the subscriber’s home operator. At
the most basic level, roaming typically requires the ability to re-
use authentication credentials provided and provisioned by the
home operator in visited networks, successful user and device
authentication by the home operator, a mechanism for billing
reconciliation, and, optionally, access to services available over
the Internet.
AAA
AAA refers to a framework, based on IETF protocols (RADIUS
or Diameter), that specifies the protocols and procedures for
authentication, authorization, and accounting associated with
the user, MS device, and subscribed services. WiMAX networks
based on this framework and alignment around recommended
authentication schemes (EAP-AKA, EAP-TTLS, EAP-TLS) will
enable:
• Protected authentication, with roaming across WiMAX
networks, as well as inter-technology roaming
• Simplified “one bill” accounting
Smart Card Re-use
Smart card technology will become a key component of laptop
communication functions. The latest smart card standard, USIM,
supports multiple service credentials on a single smart card
(UICC). Smart card re-use on laptops is under investigation
for support of seamless authentication while roaming across
technologies (WiMAX, Wi-Fi, 3GPP, and 3GPP2 networks).
Services/ApplicationsIn order for innovative applications and services to be devel-
oped which utilize the functions and capabilities of the laptop,
open application presentation interfaces need to be defined as
part of the guide, enabling developers to create solutions that
provide users with a rich mobile Internet experience. Key areas
to be addressed include:
• QoS. User control of bandwidth/latency across multiple,
simultaneous applications via policy management.
• Location. Network- or platform-based location information.
• IMS. Integrated client on laptop.
• Device management. Remote configuration, monitoring,
performance, and capability enhancement.
