WiMAX is an acronym that stands for Worldwide
Interoperability for Microwave Access, a certification mark for
products that pass conformity and interoperability tests for the
IEEE 802.16 standards.
Products that pass the conformity tests for WiMAX are capable of
forming wireless connections between them to permit the carrying of
internet packet data. It is similar to WiFi in concept, but has
certain improvements that are aimed at improving performance and
should permit usage over much greater distances.
IEEE 802.16 is working group number 16 of IEEE 802, specializing in
point-to-multipoint broadband wireless access.
