Wi-MaxWi-Max (Worldwide Interoperability for Microwave (Worldwide Interoperability for Microwave Access) is a wireless broadband technology.Access) is a wireless broadband technology.

Which supports point to multi-point (Which supports point to multi-point (PMPPMP) ) broadband wireless access.broadband wireless access.

Wi-Max Wi-Max is basically a new shorthand term for IEEE is basically a new shorthand term for IEEE Standard 802.16 . Standard 802.16 .

The IEEE wireless standard has a range of up to The IEEE wireless standard has a range of up to 50 kilometers50 kilometers. .

Can deliver broadband at around Can deliver broadband at around 75 megabits 75 megabits per second. per second.

The 802.16The 802.16, Wi-Max , Wi-Max standard was published in standard was published in March 2002 and provided updated information March 2002 and provided updated information on the Metropolitan Area Network on the Metropolitan Area Network (MAN) (MAN) technology. technology.

The extension given in the March publication, The extension given in the March publication, extended the line-of-sight fixed wireless MAN extended the line-of-sight fixed wireless MAN standard, focused solely on a spectrum from standard, focused solely on a spectrum from 10 10 GHz to 60+ GHz.GHz to 60+ GHz.

This extension provides for non-line of sight This extension provides for non-line of sight access in low frequency bands like 2 - 11 GHz. access in low frequency bands like 2 - 11 GHz.

These bands are sometimes unlicensed. These bands are sometimes unlicensed.

This also boosts the maximum distance from This also boosts the maximum distance from 31 to 50 miles and supports PMP (point to 31 to 50 miles and supports PMP (point to multipoint) and mesh technologiesmultipoint) and mesh technologies
