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 "6�6 Connecting to virtual
private networks".
