**3.1.2 WiMAX**

WiMAX (Worldwide Interoperability for Microwave Access) is based on IEEE 802.16 standard and aims at providing wireless data over long distances in a variety of ways, from point-to-point links to full mobile cellular type access. WiMAX provides support for mobility and it will fill the gap between 3G and WLAN standards. It offers high data rates (<40Mb/sec), portable connectivity at low speeds (<60km/h) and wide area coverage (<10km) required to deliver high speed internet access to mobile clients. WiMAX provides a wireless alternative to cable and xDSL for last mile broadband access and can be used for V2I or I2I long range communication. At this point it should be mentioned that WiMAX supports several service levels including guaranteed Quality of Service (QoS) for delay sensitive applications and an intermediate QoS level for delay tolerant applications that require a minimum guaranteed data rate.
