Amdocs, the market leader in customer experience software solutions and services for communication service providers released its 2016 State Report of the Radio Access Networks (RAN). In its report, Amdocs calls for optimization of Radio Access Network to go on par with the increasing demand for data and network complexity.
According to the research data, Voice-over-LTE (VoLTE) call drops can be four to five times higher than calls on 2G or 3G networks. VoLTE offers operating expense (OPEX) and capital expense (CAPEX) reductions by repurposing 2G and 3G services. However, post-deployment, VoLTE can be less stable compared to the traditional voice services.
The research also said that the network data demand is on surge across the globe for every operator at an estimate of 60% year-on-year. This is mainly due to increased demand for video on devices providing better entertainment opportunities to the mobile users. However, the study pointed out only 5-15% of Wi-Fi traffic goes through mobile devices.
Around 75% of the network traffic in cities is used within buildings. At the time of network congestion, indoor users face up to 25% increase in network issues than the outdoor users. During music and sports events, 70% of the attendees send at least one text message causing spikes in network usage. This finding hints that there is a considerable amount of communication happening at the event venues through emails, texts or social media.
Finally, the data also said that the international roamers upload 50% of the data while at events than the non-roamers. However, their network experience can be 25% worse.
Operators can understand the diverse usage patterns and better optimize the services, which can lead to monetization. The research findings are based on analysis of more than 25 million voice and data connections from 80 different network operators around the world in the past 12 months.
