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.

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.

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.
