Optimize Performance Over Wireless Networks
Mobility XE’s Wireless WAN Optimization automatically reduces network consumption and improves throughput and application responsiveness, particularly over bandwidth-constrained or wireless networks.
Other VPNs typically degrade performance, especially over wireless networks, often by as much as 50%. Mobility XE uses link optimizations to reduce the number of retransmitted packets, excess control information and other network "chatter," and dramatically improves throughput by compressing data and images. Best-Bandwidth Routing technology ensures the fastest and most efficient available network connection is used.
There are many behaviors of TCP/IP that make it less than optimal in a wireless environment. To address these, Mobility XE is designed to provide optimum performance over intermittent and bandwidth- challenged network links. Its architecture includes enhancements that allow network traffic over IP to more effectively deal with momentary loss of connectivity from a mobile device, whether due to coverage outages or external factors, such as power management or user intervention. It makes the most efficient use of the given bandwidth using many advanced features that reduce the “chattiness” of transport protocols:
Working in concert with one another, these advanced features provide for the most efficient movement of data. In addition, when “Use Fastest Interface” is enabled (the default), Mobility XE automatically switches to the fastest bandwidth network connection when multiple connections are active.

- Selective acknowledgments
- Data and acknowledgment bundling
- Message coalescing
- Reduced and synchronized retransmissions
- Fragmentation optimizations
- Data compression
- Error-reduction algorithms
- Web acceleration
