Network operators are likely to face new challenges in achieving optimal network utilization as LTE and heterogeneous networks (HetNets) continue to grow. The multivendor nature of HetNets could give rise to interoperability issues between cellular sites, thereby negatively affecting the quality of service experienced by the end user. The higher degree of automation apparent within self-organizing networks (SONs) will help enhance network utilization significantly. This implementation of SONs by network operators, in turn, will translate to greater uptake of SON-specific testing and monitoring solutions.
The presence of legacy-based networks could weaken the market for SON testing and monitoring equipment. Thus, it is vital to encourage network operators to replace legacy-based testing methods with new and innovative ones. Enhanced customer service and the offer of various value-added services that help prospective buyers understand the need for better solutions will support test equipment vendors’ efforts to promote the testing of SON-enabled infrastructure.
In an effort to provide a holistic solution to its end users, SON testing and monitoring equipment vendors have tried to fill the apparent gaps in their portfolio by merging with or acquiring smaller companies. Key acquisitions include that of Tektronix Communications by Netscout, Swissqual by Rohde & Schwarz, Trendium by JDSU (now rebranded as Viavi Solutions) and Anite by Keysight Technologies.
Recent research from Frost & Sullivan, detailed in the report Analysis of the Global Self-Organizing Network (SON) Testing and Monitoring Equipment Market, finds that the market earned revenues of $865.5 million in 2014 and estimates this to reach $1,877.8 million in 2020. The study covers probe-based network monitoring, probe-agnostic network analysis and optimization, drive testing equipment and network infrastructure testing.
