Over the past few decades, significant advances have been made in telecommunications technologies. As a consequence, it has become a complex issue for regulators and investors to assess various technologies on their own, their inter-working, how they maybe optimally developed and how best to transition from one to another. Moreover, these advancements have blurred the dividing line between wired and wireless. This has further compounded the problem of evolving regulatory regimes to match these developments, including devising migration plans and roadmaps for regulators and investors alike. Understanding the underlying technologies, infrastructure, applications, technologies inter-working and evolutions is a fundamental input into the development of appropriate strategies to fulfil present and future needs across various ICT sectors. This generally demands knowledge across a number of disciplines to ensure offering clients the best fit and most cost effective solution.
