Introduction

WiMAX, meaning Worldwide Interoperability for Microwave Access (also known as IEEE 802.16), is a telecommunications technology that provides wireless transmission of data using a variety of transmission modes, from point-to-multipoint links to portable and fully mobile internet access.

WiMAX is designed to enable pervasive, high-speed mobile Internet access to the widest array of devices including notebook PCs, handsets, smartphones, and consumer electronics such as gaming devices, cameras, camcorders, music players, and more. As the fourth generation (4G) of wireless technology, WiMAX delivers low-cost, open networks and is the first all IP mobile Internet solution enabling efficient and scalable networks for data, video, and voice. As a major driver in the support and development of WiMAX.

It can provide broadband wireless access (BWA) up to 50 km for fixed stations, and between 5 - 15 km for mobile stations, in contrast, the WiFi/802.11 wireless local area network standard that is limited in most cases to only 30 - 100m.

WiMAX can be used for wireless networking in much the same way as the more common WiFi protocol. WiMAX is a second-generation protocol that allows for more efficient bandwidth use, interference avoidance, and is intended to allow higher data rates over longer distances.
