Think of it as the “Super Bowl Effect.” At this year’s Super Bowl XLVI in Indianapolis, Indiana, USA, 60% of mobile traffic was uplink traffic. In the future, the use of video and other bandwidth-heavy mobile applications is set to grow even further. At the Super Bowl, fans uploaded more data to the network than they downloaded, 125 GB compared with 90 GB. They were busy sending photos, videos and messages to their social networks like Facebook and Google+, and to friends who weren’t able to be there. While the Super Bowl is a special case that requires extra resources to ensure performance, it is not always possible to allocate so much extra firepower to each and every event.

Continuous Packet Connectivity (CPC) provides another option. Take the example of the European soccer championship that is currently in full swing or upcoming events in London, where sufficient bandwidth capacity in the uplink is crucial.  To meet this demand, HSPA+ radio network extensions are bundled with features that enable more uplink capacity, higher data rates and less smartphone battery consumption. Experts at Nokia Siemens Networks’ Smart Labs have tested the feature set Continuous Packet Connectivity using commercial Nokia Siemens Networks radio equipment.

The figures below underline the striking benefits of Continuous Packet Connectivity:

• 5x more HSPA+ capacity (users)
• 4x more cell throughput (Mbps)
• 15% more smartphone battery life time (hours)

They are also clear evidence that this feature set is a very efficient way to increase upload capacity and improve the user experience especially when subscribers are uploading pictures, videos and files in social media and other services. So, there is every reason for mobile operators to prepare for ‘the Super Bowl effect’ and get ready now for the next major event in their market.
