Dynamic Spectrum Access is the Solution: Whats the Problem?
Dynamic access to spectrum evolved as a concept from an observation that much spectrum was under-utilized. Over time the access rules for this spectrum have changed to geo-location and it has become clear that the spectrum is often subject to interference. This has changed the thinking about the applications most likely to emerge away from classic unlicensed uses such as device-to-device and home networks and towards wide-area machine-to-machine networks and rural broadband. Such applications would prefer somewhat certain access to spectrum so further enhancements to access rules to prioritise certain users should be considered.
