Mobile Handsets
With the announced and soon-upcoming volume availability of mobile WiMAX handsets, users
will have the ability to enjoy full broadband data services with the seamless mobility they are
used to on today’s voice-centric cellular networks.
2.4.2 Core network
The core network plays an important role in the 802.16e eco-system. Several elements are
located in the Network Operation Center (NOC) and we briefly describe each here.
2.4.2.1 Management
A Network Management System (NMS) and/or an Element Management System (EMS)
provides for configuration, provisioning, and management of the base station and subscriber
stations. It provides alarms, traps, statistics, and more. The PureView NMS (Figure 11) is a
carrier-grade multi-platform NMS/EMS that provides all of these capabilities.

2.4.2.2 AAA
An Authentication, Authorization and Accounting System (AAA) is required by 802.16e to
authenticate and track subscriber devices within the network. PureWave Base Stations are
tested for interoperability with several options of AAA servers:
• Free Radius AAA
o Version 2.1.7 Linux
o Version 1.1.7 Windows
• Cisco AAA (CAR-4.2)
2.4.2.3 ASN-GW
An Access Service Network Gateway (ASN-GW) is designed to support connection management
and mobility across sectors, cell sites, and even across service provider network boundaries
(roaming capabilities). An ASN-GW can coordinate inter-base station traffic, as well as traffic
between base stations and the core network. Simply, the ASN-GW is the gateway between the
Radio Access Network and the Core Network.
