目次

Capital spending on the radio access network will see only a small year-on-year increase this year, but there will be an increase of almost 10% in 2015. This will not be driven primarily by conventional equipment, though the rise in volume roll-outs of LTE worldwide will be an important factor. Instead, there will be a significant shift in operator budgets towards new HetNet platforms, driven by advanced software, virtualization and new access points.

This will see a very different, and fragmented, pattern of RAN investment emerging in the next five years, as forecast in detail by the latest biannual report from Maravedis-Rethink's RAN Service, entitled Towards the hyper-dense network - the shape of the HetNet 2013-2019. Although first-wave LTE networks have generally followed familiar patterns, focusing on coverage and low frequency bands, operators are making detailed plans to add capacity and density using a mixture of tools including small cells, carrier WiFi and new macro antenna technologies.

However, these dense, multilayered deployments will not gather pace until 2015 onwards. An improving economic climate will green-light some major expansions, especially in Europe, but most carriers are also holding out for two key developments which will improve the business case.

One, before embarking on dense small cell roll-outs, they are waiting for 3G/4G/WiFi multimode access points at affordable prices and for advanced SON (self-optimizing network) tools. This combination should be mainstream in early 2015, sparking a rise in public access metrocell new deployments from 65,000 in 2013 to over 4.3m in 2019. Two, they are delaying major new HetNet projects until there are standards-based platforms for virtualization. Although few carriers will deploy full Cloud-RAN until 2018 or later, 62% say they will introduce elements of virtualized processing to their HetNets in 2015 to 2018.

The Maravedis-Rethink service analyzes and models the mobile broadband deployment plans of the top 40 operator groups (over 170 companies), on a carrierby- carrier basis, to produce a series of reports and research notes. In its most recent study, conducted in April-May 2014, it examined the most important decisions carriers are making, spoke to those companies which had already made them, and assessed the real world uptake of key architectures, as well as forecasting adoption rates. The researchers also carried out extensive interviews with the entire RAN vendor base and supply chain.

The result is a detailed examination of how RAN platforms, both hardware and software, will evolve in the period to 2019, and the economic benefits carriers expect to gain from the new networks. Based on analysis of current cutting edge deployments as well as the future plans of operators and the ecosystem, the report provides market sizes, forecasts and capex values for the key elements of the new RAN - cells of all sizes, carrier WiFi, virtualization technologies for the RAN, emerging MIMO platforms, and self-optimizing networks (SON).
