Measuring QoE is difficult and even more difficult is to identify the source of QoE issues within the network. You can download or watch the full interview with Paul Gowans and Ronnie Neil to learn more about Viavi’s approach to end-to-end network optimization based on QoE assessments.

Read the full interview to learn about Ascom’s approach to ensure that testing and monitoring in mobile networks captures the complexity of QoE, and guides operators to optimize their network resources in real time. This interview is part of our report "Getting the best QoE: Trends in traffic management and mobile core optimization".

The desire to optimize the mobile network is a no-brainer. Who could possibly not want to extract the best performance, the most revenues out of the existing, already deployed mobile network infrastructure? Indeed, mobile operators have been optimizing their networks from the beginning, trying to pack as many voice calls as possible. And then trying to pack as many bits – either voice, video or data – as possible.

What's after the RAN optimization report? Core optimization, although I am no longer sure that the two can be kept separate. I am doing the research now, so if there is something you would like to share let me know.

At Astellia, troubleshooting, monitoring, automation and geolocation are the three pillars to support RAN optimization. With Vicent Soler, in the CTO Office of Astellia, we talked about how operators can rely on this functionality to improve performance and subscriber experience in their networks.

Telstra has been very proactive in moving towards automated RAN optimization, small cells, and carrier aggregation (CA). In this conversation with Stephen Howell, General Manager at Telstra, we discussed their learning experience and the benefits that these solutions bring to Telstra. A key learning point is the importance of automation in managing small cells.

The transition to C-RAN and fronthaul has started with operators gradually moving to the new architecture to realize a better utilization of network resources. We discussed with Femi Adeyemi at Fujtsu the drivers and benefits of C-RAN over the traditional distributed architecture for RAN optimization.

In our conversation with Kashif Hussain, Solutions Marketing Manager at Viavi Solutions (until recently JDSU), we talked of how RAN optimization is changing with the introduction of multi-layered HetNets and the transition to dynamic networks in which the RF environment keeps changing. Networks are becoming more complex, and there is more equipment to optimize.
