Venturi Products Address

Key Operator Challenges

Maximizing Network Efficiency

Meeting Subscriber Expectations

Broadband speeds with mobile advantages

Consistent experience in all locations, at all times

Access to a wide range of media-rich services

Lower CAPEX and OPEX per sub

Efficient utilization of RAN resources and spectrum

More services and broader coverage at lower cost


8/468

Optimization Benefits Both

Subscribers andOperators

Superior User Experience

Compelling Economics

Improved Spectral UtilizationMore subscribers and services per Hz

Lower Cost to Serve15-30% reduction in network CAPEXtogether with lower customer care costs

Faster Data SpeedsIncreases up to 3X or more

Increased ReliabilityFewer session drops and connection

time-outs

Consistent performance undervarying RF conditions

Larger effective coverage area

Service Consistency

TCP/IP Dramatically Underutilizes Available

Network Bandwidth

Only a fraction of available bandwidth is used Bandwidth efficiency varies as quality of wireless link

fluctuates

Transactions abort frequently

TCP/IP Also Hurts Service Quality

Wireless Transport Optimization

Venturi Transport Protocol (VTP)

TCP is designed for Wired linenetworks

Latency < 50ms

Packet Loss < 1%

TCP does not perform wellunder typical wireless network

characteristics Latency 100ms to 4000ms

High amounts of jitter

Packet Loss 3% to 10%

TCP has performance issues

Treats every cases of packetloss as congestion

Slow response to networkcharacteristic changes

Expensive restart aftertemporary loss of link

Backhaul /OPEX Reduce bytes traveling over

the network by 2x or more

Less infrastructure means

lower maintenance andrecurring costs

Better, more consistentperformance translates intofewer customer care calls

US$6 - $20 per customer carecall it adds up!

Accommodate more users /data on existing infrastructure

Expand usable data services

footprint; reduce BTS datacoverage requirement

Better experience drivessubscriber loyalty
