Wireless Applications vs. Periodic Synchronization

Wireless Link

Periodic Synchronization

 Appropriate for certain tasks – e.g. email

 Bandwidth Hungry, but not always on

 Sensitive data stored locally

 Helper Applications sometimes not available for PDA’s

 Difficult to Distribute and Support Applications

 Local Devices become obsolete with new Application versions

 Access to data anywhere, anytime, from any device

 Focus on business objectives - not IT issues

 Support any application necessary

 Provide high computing power centrally
