“By year-end 2011, 70% of all new worldwide voice and data client-to-LAN connections will be wireless”
Wireless networks used to be a matter of convenience – allowing network access in boardrooms, some classrooms, common areas for staff, customers, and guests. With advances in wireless technology over the past few years and particularly with the IEEE 802.11n standard ratified, wireless technology is now capable of even replacing the edge of LAN networks and becoming the primary means of accessing mission critical data, voice and video content and applications.
Where WiFi is used instead of a wired LAN significant savings can accrue. CAPEX per user:
Network Strategy Partners, 2008
An 802.11n “optimized” network can deliver up to twice the range and five times the bandwidth of a 54-Mbps 802.11g wireless network. For organizations downloading large files or pre recorded rich media training content 802.11n makes wireless a practical solution. Depending on the type of files being transferred and the degree of network optimization results can be dramatic:
Transferring a 30-minute video file over an 802.11g network took approximately
10 minutes. Over an 802.11b network it took approximately 42 minutes. Over an
802.11n network it now takes approximately 44 seconds!
