WiMAX is a broadband radio access

technology based on the IEEE 802.16

protocol. To apply this technology, you need

to be familiar with the basic concepts and

technology benefits of WiMAX.

This document describes the basic concepts,

application scenarios, and network structure

of WiMAX.

WiMAX based on the IEEE802.16 protocol is a broadband wireless technology appliedto the Metropolitan Area Network (MAN).It complies with the "Broadband + Wireless" trend. WiMAX features the OrthogonalFrequency Division Multiplex Access (OFDMA), Multiple Input Multiple Output (MIMO),and other advanced technologies to maintain its broadband advantage.It is called "3.5G" or "4G" technology. In October of 2007, it becomes the fourth standardof 3G technology.

Protocols

WiMAX is based on the 802.16 protocol that has two standards:

802.16dFixed broadband radio access standard

It specifies the air interface layer between the fixed access

terminals and the BTS.

802.16eMobile broadband radio access standard

It supports the mobile station.

It supports both the fixed broadband radio access system and

mobile broadband radio access system.

Interface Introduction

Interface Description

R1 R1 interface between the MS and the ASN as the air interfacespecification for (PHY and MAC)

R2 R2 is the interface between the MS and the CSN associated with

Authentication, Service Authorization, IP Host configuration management,and mobility management. R2 is a logical interface and does not reflect adirect protocol interface between the MS and CSN.

R3 R3 is the interface between the ASN and CSN to support AAA, policyenforcement and mobility management capabilities. In addition, R3encompasses the bearer plane methods (e.g., tunneling) to transfer IPdata between the ASN and the CSN.


12/15


Interface Introduction

Interface Description

R4 R4 consists of a set of control and bearer plane protocols originating andterminating in various entities within the ASN that coordinate MS mobilitybetween ASNs.

R5 R5 consist of a set of control plane and bearer plane protocols for interworking between CSNs

R6 R6 provides the communication between the BS and the ASN GW whichprovides a set of control and bearer plane protocols.

R8 R8 is a set of control plane message flows and in some causes, bearer plane data flows between the BS to ensure fast seamless handover.
