CHAPTER 1. Overview of Mobile

WiMAX System

1.1 Introduction to Mobile WiMAX

The Mobile WiMAX system is the wireless network system that supports IEEE 802.16e-

2005 base service. The IEEE 802.16 standard constitutes the basis for Mobile WiMAX, and

includes IEEE Std 802.16-2004 which defines the fixed wireless Internet connection

service, and IEEE Std 802.16, P802.16-2004/Cor/D3 which defines mobility technology

such as handover or paging.

Mobile WiMAX Standard

In this description, the entire Mobile WiMAX standard is expressed IEEE 802.16.

The wireless LAN (WLAN, Wireless Local Area Network) can provide high speed data

services, but its radio wave is short and covers only small areas, and also gives limited user

mobility. It is difficult for WLAN to ensure Quality of Service (QoS) for data service.

On the contrary, the present mobile communication networks support the mobility of the

users, but the service charge and the cost of system operations are high due to the limited

wireless resources. To provide faster service in the existing mobile communication

networks, it requires a separate wireless communication technology such as High Speed

Packet Access (HSPA) for the data services.

Mobile WiMAX can, therefore, overcome the limitations of the WLAN and present mobile

communication networks, and accommodate only the advantages of the system.

Mobile WiMAX can ultimately provide the high speed wireless internet services with low

cost at any time and in anyplace.

Samsung Mobile WiMAX System provides high speed data services using the transmission

technology of Orthogonal Frequency Division Multiple Access (OFDMA) by the Time

Division Duplex (TDD), and can give wider coverage compared to the existing WLAN.

The system performance and the capacity have been expanded by the high performance

hardware, and thus, it can easily give various functions and services to the users.
