Abstract—One of the technologies that can lay the foundation for the next generation (4G) of mobile broadband networks is popularly known as ``WiMAX." WiMAX stands for Worldwide Interoperability for Microwave Access and is designed to deliver wireless broadband bitrates, with Quality of Service (QoS) guarantees for different traffic classes, robust security, and mobility. This article provides an overview of mobile WiMAX, which is based on the wireless local and metropolitan area network standards IEEE 802.16-2004 and 802.16e-2005. We introduce WiMAX and focus on its mobile system profile and briefly review the role of the WiMAX Forum. We summarize the key points of the WiMAX network reference model and present the salient characteristics of the PHY and MAC layers as specified in IEEE 802.16-2004 and 802.16e-2005. Then, we turn our attention to how mobile nodes enter a WiMAX network and explain the fundamentals of mobility support in WiMAX. Finally, we briefly compare WiMAX with HSPA, another contender for 4G.
