10�1�5 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”�
