VPN

A VPN, or Virtual Private Network, allows organisations to use the Internet for corporate data communications. With a VPN, organisations can use the Internet as if it was their own enormous Wide Area Network, connecting remote offices together and providing remote access to the corporate network for mobile workers whilst away from the office. A VPN basically consists of some sort of device that encrypts data before sending it through the Internet to another VPN device in another office, or to a remote user with VPN software on their laptop. In essence, a VPN lets you "borrow" the Internet for your own data communications.

VPN while providing secured connection to the Intranet has its complexity.

Mobile private network on the other hand has features of a VPN but also rendering mobile computing experience.

With Mobile Private Network, your connection is seamless and pervasive.

For example, if your client is loaded with MPN software client and has blue tooth capability and also an 802.11x or an Ethernet installed. While in the office, you may use your lan. When you get out in the field to do you stuffs MPN client detects available connection when needed. Your blue tooth kicks in connecting to the Internet through your blue tooth handphone (GPRS) and tunnel you through to your Intranet and also encrypting your data Blowfish/DES/AES whilst deliveringyour data. If an 802.11x hotpsot is detected, it seamlessly changes the tunnel connection through the AP instead without killing your application. The same happens when you get out of the AP range, it switches you back to your GPRS connection. Hope this helps.
