A new paradigm shift in spectrum access is the so-called dynamic spectrum access (DSA) by which spectrum is allocated on a dynamic basis in response to changes in the operational environment exemplified by spectrum demand, type of service, and regulatory constraints. Consequently, this new paradigm has many impacts on current regulatory regimes, which naturally affect other telecom market players. This paper analyzes these impacts and evaluates the strengths, weaknesses, opportunities, and threats (SWOT) associated with the DSA trend and then highlights the enabling mechanisms for DSA.
