“The term used to describe a network based on older, outdated
protocols. For example, any network not based on the IP (TCP/IP)
protocol — like IPX or SNA — is considered a legacy
network. In wireless networks, the term is used to describe
networks based on older 802.11x standards that predate the 802.11n
standard. The legacy standards include 802.11a, 802.11b, and
802.11g.”
