What is a Mobile VPN?
A Mobile VPN is a VPN that is designed and optimized to work with mobile info and wireless networks. Because legacy VPNs were designed for site-to-site and for stationary user security, they are cumbersome to use and are incapable of providing the persistent security and the seamless roaming that are required for mobile users.
Mobile VPN refers to a mobile virtual private network. The word private as used here is not necessarily due to high privacy protection or security features provided by such networks. However, a mobile VPN can utilize the security features of underlying resources. The main “job” of the mobile VPN is to create seamless transfer of data or communication over different types of systems, technologies, and networks. For a simple example of how mobile VPN works, let’s take a look at a busy executive. This person may move from the desktop computer at the office that uses broadband, to a palmtop that requires a wireless hot spot while en route to his next location, and then finally to his laptop when he arrives at his hotel room for a meeting. The hotel may utilize a LAN or local area network, which combines one or more other systems that communicate via the same dedicated line or wireless connection. As the executive moves between various technologies and networks, his IP or Internet Protocol
The third-generation VPN, called the mobile VPN, is based on the TLS protocol, which has been optimized specifically for low bandwidth networks and mobile devices. A mobile VPN provides the same level of security as the traditional wired VPN solution but it is optimized for the challenges of the wireless world. It provides session persistence and inter-network roaming to create a consistent and seamless user experience when the devices switch networks or move out of coverage. Advanced data compression increases the throughput and also provides good performance in wireless networks with small bandwidth. Additionally, a true mobile has a much smaller memory footprint and uses less processing power than a traditional VPN, enabling applications to run faster while the battery lasts longer. Why a mobile VPN? Traditional VPNs are designed for fixed networks characterized by high bandwidth and low delay and jitter, where data loss mainly occurs due to congestion. When wired VPN technology is
