As of 2010 Wi-Fi
technology had spread widely within business and industrial sites. In
business environments, just like other environments, increasing the number
of Wi-Fi access-points provides redundancy, support for fast roaming and
increased overall network-capacity by using more channels or by defining
smaller cells. Wi-Fi enables wireless voice-applications (VoWLAN or WVOIP).
Over the years, Wi-Fi implementations have moved toward "thin"
access-points, with more of the network intelligence housed in a centralized
network appliance, relegating individual access-points to the role of mere
"dumb" radios. Outdoor applications may utilize true mesh topologies. As of
2007 Wi-Fi installations can provide a secure computer networking gateway,
firewall, DHCP server, intrusion detection system, and other functions.
