LTE changed the paradigm for mobile network operators and now, 4G is rapidly becoming standardized across the globe. Recent figures published by the Global Mobile Suppliers Association indicate that 288 operators have already launched LTE and it is now available in 104 countries around the world. The move has brought with it a number of new use cases such as video streaming and online gaming, plus the highly anticipated Voice over LTE (VoLTE) which is leading to high-quality voice and video calling services being delivered over mobile networks.
Yet, with this transformation taking place, it is no longer enough for operators to simply maintain their networks for traditional voice, messaging and data. As a result of this paradigm shift in telecommunications, it is now vital that operators develop a much better understanding of the network complexities and the ways subscribers engage with the network. However, this needn’t be an expensive or time consuming process, as operators already have access to this information – it’s hidden within the mobile network; all that’s required are the right keys to uncover it.
Operators that implement end-to-end service assurance and optimization tools covering the entire network from the RAN to the core can unlock this valuable data. RAN management and optimization is vital to delivering on the potential of LTE as it holds the keys to ensuring quality network performance for subscribers. But it comes with its own set of challenges, as historically it has been a very costly exercise for mobile operators. Not only that, but 70 percent of subscriber issues now occur inside the RAN, and at least 10 percent of those problems are not resolvable with existing monitoring workflows. So it comes as no surprise that having a better and more affordable approach to tackling the RAN is now a key technical and financial differentiator for operators, particularly as they’re also looking to recoup the considerable investments they’ve made on LTE network build-outs.
