In our recent blog posts, we have looked at different aspects of Total Cost of Ownership (TCO). CapEx spending gets the headlines and for good reason. Flattening revenues driven by lower revenue per bit coupled with explosive growth in bandwidth demands have made it difficult for carriers to achieve the industry’s standard goal of 15%–20%
In our last post, we discussed how service provider revenues are massive but have settled into a low growth rate of around 1 % per year. How does this affect CapEx? Network operators can drive new sources of revenue because they invest in their networks. Service provider CapEx is a source of intense interest because
By any measure, the telecommunications industry is huge. According to GSMA Intelligence, total mobile revenues reached $1.05 trillion in 2017 and will break $1.1 trillion in 2020.
