[. . . ] The IEEE 802. xx is a set of specifications for LANs from the Institute of Electrical and Electronic Engineers (IEEE). Most wired networks conform to 802. 3, the specification for CSMA/CD-based Ethernet networks or 802. 5, the specification for token ring networks. 802. 11 defines the standard for wireless LANs encompassing three incompatible (non-interoperable) technologies: Frequency Hopping Spread Spectrum (FHSS), Direct Sequence Spread Spectrum (DSSS), and Infrared. IEEE standards ensure interoperability between systems of the same type. [. . . ]
