Planning for the Future of Enterprise Wi-Fi


Published on

The capital cost and productivity advantages of Wi-Fi over cabling every cube, and the substantial performance
improvements of 802.11n over previous generations of Wi-Fi, make 802.11n WLANs the primary user network
connection in tomorrow’s enterprise. Learn why this is the case and the implications for your network.
