Six Mobility Must-haves
Mobility in mind: Look for these six mobility must-haves: 1. Roaming and seamless connectivitySeamless 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.
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.
