Communication using wireless links requires the use of radio spectrum, which can be licensed or unlicensed depending on the frequencies selected. For licensed spectrum, users of wireless communication devices can expect a certain level of protection from interference from other wireless devices, but this protection can sometimes break down in areas near national borders, for instance, where licenses from one country conflict with those issued by those in its neighbour. Unlicensed operation offers no protection from interference, and radio operators may find their communications interrupted at any time by other wireless devices operating in their vicinity. A possible way to solve this problem is to allow radio operators to jump to a new frequency when they experience interference. The question then becomes to which frequency the operator should switch in order to obtain the best Quality of Service (QoS) for the application they are currently using. Randomly selecting a frequency (frequency-hopping) is a sub-optimal solution as it does not guarantee that the new frequency is any better than the frequency that was just vacated. Frequently switching frequencies also needs to be avoided as each time the frequency is changed there is a cost in terms of connection disruption resulting in possible lost packets. The Policy-Based Spectrum Management system attempts to show how a policy-based system could be used to dynamically select spectrum based on application QoS requirements. This
