Adaptive Airlink Optimization is at the core of the Mobile Operator Solution. It transparently replaces TCP over the airlink with the patented Venturi Transport Protocol (VTP), which was specifically designed to overcome the inefficiencies related to wireless data transport. VTP optimizes TCP-based applications, including Web, streaming video and audio, email, enterprise applications and file transfer. Adaptive Airlink Optimization offers wireless carriers a range of benefits:

• Superior Performance
  Adaptive Airlink Optimization boosts performance by adapting packet rate transmission on a session-by-session basis so that data can be transmitted at the fully available network speed. Venturi's Smart Compression applies best of breed compression technology to yield unmatched performance enhancement.
• Enhanced Coverage
  With Venturi, users benefit from high, consistent performance in all types of RF conditions. In contrast, TCP allows data throughput speeds to drop much more dramatically in areas with poor signal quality, as shown below.
  
• Improved Consistency
  Under poor RF conditions, Venturi users experience far fewer dropped sessions and connection time-outs, since VTP avoids TCP congestion control reactions that cause high latency and back-offs.
• Greater Network Efficiency
  By eliminating unnecessary data retransmissions and shortening connection times, Adaptive Airlink Optimization more efficiently utilizes network bandwidth.
