via USB or as a portable Wi-Fi access point (refer to “7�5 Sharing your
phone's mobile data connection”).
11�1�9 More\VPN
A mobile virtual private network (mobile VPN or mVPN) provides mobile
devices with access to network resources and software applications on
their home network, when they connect via other wireless or wired
networks. Mobile VPNs are used in environments where workers need
to keep application sessions open at all times, throughout the working
day, as the user connects via various wireless networks, encounters
gaps in coverage, or suspends-and-resumes their devices to preserve
battery life. A conventional VPN can't survive such events because the
network tunnel is disrupted, causing applications to disconnect, time
out, fail, or even the computing device itself to crash.
For more information on VPN, refer to “7�6 Connecting to virtual
