WiMax 802.16e standard is a revision of previous 802.16 versions. Essentially, the IEEE 802.16e standard is mobile WiMax, a significant development from fixed WiMax solutions and implementations. IEEE 802.16e sets the standard mobile WiMax system profiles. It also includes several conformance and functionality standards to establish the global interoperability of mobile WiMax solutions and technologies.
The WiMax Forum is responsible for creating the set of standards for mobile WiMax solutions. The standards were ratified by IEEE in 2005. It is now being followed by hardware manufacturers and service providers that deploy WiMax technologies.
WiMax 802.16e or mobile WiMax is designed to provide end-users with high speed broadband connections using wireless devices. It is designed to enable municipal wide area networks to have the utilities and capability for wireless connectivity. It can match the usefulness of WiFi on local area networks and can also match its capabilities to deliver high speed data throughputs. In fact, mobile WiMax can serve as backhaul architecture of LAN WiFi hotspots enabling users to widen their area of coverage.
IEEE 802.16e mobile WiMax can actually transfer data, voice and video services on home networks, office environments, and anywhere where there is WiMax coverage. Portability of broadband connections therefore can be achieved not just by business users but also by home users. Mobile WiMax can also enhance the usefulness of high end cellular devices as these can be used to establish fast and reliable Internet connections.
The IEEE 802.16e standard is also being implemented on peripheral WiMax devices that will use the technology. Such devices such as PDAs, laptop chipsets, and smart phones should follow the standards so that they can be used on WiMax connections.
