The major challenge facing communications service providers (CSPs) is not about handling ever-growing bandwidth demands without increasing Capex. Smart selection of network technologies that leverage advances in aggregating, routing, and transmitting bits largely have the answer for that. The much more pressing challenge is on the services front, from competition, substitution, and the inability to maximize revenues. These concerns reduce the top line and restrict CSPs’ ability to maneuver.
In modern communications networks the demand for more speed and more capacity to drive ever more advanced services has been at the heart of network development – especially in the mobile space. Even the generational numbers hint at the increases – 3G, 4G, 5G - every change indicating an increase, every change indicating something that is somehow bigger and better. And, of course, the impression created is largely correct.
