Mobility in mind: Look for these six mobility must-haves:
1. Roaming and seamless connectivity
Seamless roaming helps users remain connected as they cross network
boundaries and use different radio access networks. A mobile VPN allows the
user to move around, switch networks and change connection without any
interruptions to the application-creating an "always-on" scenario. It also
recovers all the data after a lost signal or hibernation mode, ensuring that
data is never lost.
2. Session persistence
Unstable connectivity is common in the wireless environment, and mobile
devices will sometimes lose the connection or hibernate to save battery power.
Session persistence with transaction recovery allows users to continue working
without the need to reauthenticate or restart the application after a lost
signal, change of network type or hibernation mode. Mobile workers improve
productivity with a persistent and secure connection to enterprise applications
as they roam between networks, or move in and out of coverage.
3.
Data compression
With limited bandwidth available, advanced data compression is an important
feature that increases the performance of the applications over low-bandwidth
networks. Data compression minimizes the amount of data being transferred,
allowing organizations to lower their data rates-which can be a potential large
cost savings for a company with hundreds or thousands of employees.
4.
Limited CPU power
Because mobile devices are equipped with smaller processors than desktop
computers or laptops, it is critical that the security solution require minimal
processor power so it doesn't slow down other applications running on the
machine. With less processing power, users benefit from improved speed and
extended battery life.
5.
Memory footprint
With limited memory space available, memory footprints on mobile devices
must be small to ensure there is memory dedicated to business-critical
applications. Ideally, a mobile VPN solution will have memory footprint
requirements as low as 70KB to conserve valuable storage space.
6.
Battery consumption
To conserve battery power without losing the VPN connection, it is critical
for a mobile VPN solution to provide session persistence and data recovery,
allowing the device to hibernate when it isn't being used. This extends the
operating time from each battery charge to the next, giving mobile workers
access to mobile devices for longer periods and boosting productivity.
