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.

In this conversation on RAN optimization with Philip Sorrells, Vice President of Strategic Marketing at CommScope we focused on the role antennas have in improving performance and coverage in the RAN, and how the scope for these improvements can be crucial for operators to meet the growing demand for capacity and high levels of QoE.

Data traffic is typically very spiky. Even during congestion periods, wireless networks transmission alternates between spikes and valleys and this limit the efficient utilization of the available resources. We talked to John Reister, VP of Marketing and Product Management, Vasona Networks, about how mobile operators can take control of the spikiness and manage traffic to optimize RAN utilization.

The way mobile operators optimize the RAN and maximize RAN resource utilization is changing a mobile networks become more complex, and subscribers – as well as IoT devices – use them more intensively. In this conversation with Said Mokbel, VP of Wireless Technology Development, Chief Technology Office, TELUS in Canada, we talked how IoT traffic characteristics change the way mobile operators can optimize the use of the network infrastructure they have.

How does the way we optimize the RAN change in a network environment in which both capacity and demand change continually, but the need to meet high standards of QoE remains the same? We talked about this with David FitzGerald, Director of the Office of the CTO, at Ascom.

Mobile operators have to increase capacity to meet traffic loads that continue to grow. But they need to do so in a way that is cost efficient, that improves the performance and QoE, and to achieve this they also have to optimize their network performance using real-time data.
