WiMAX, meaning Worldwide Interoperability for Microwave Access, is a
telecommunications technology that provides wireless transmission of
data using a variety of transmission modes, from point-to-point links
to portable internet access[citation needed]. The technology provides
up to 75 Mbit/s symmetric broadband speed without the need for cables.
The technology is based on the IEEE 802.16 standard (also called
Broadband Wireless Access). The name “WiMAX” was created by
the WiMAX Forum, which was formed in June 2001 to promote conformity
and interoperability of the standard. The forum describes WiMAX as
“a standards-based technology enabling the delivery of last mile
wireless broadband access as an alternative to cable and DSL”.
The terms “fixed WiMAX”, “mobile WiMAX”,
“802.16d” and “802.16e” are frequently used
incorrectly Correct definitions are the following:
• 802.16-2004 is often called 802.16d, since that was the working
party that developed the standard. It is also frequently referred to as
“fixed WiMAX” since it has no support for mobility.
• 802.16e-2005 is an amendment to 802.16-2004 and is often
referred to in shortened form as 802.16e. It introduced support for
mobility, amongst other things and is therefore also known as
“mobile WiMAX”.
