This study explored the evolution of Denton's VHF educational television assignment Channel 2, from its inception on April 14, 1952, to September 2, 1977. The problem was to discern why the channel remained inactive for twenty-five years. Chapters explore the attempts of broadcast interests to acquire control of the channel, and discuss why they were unsuccessful. The study concludes that a lack of finances, combined with the apathy and self-interests of Denton's educational leaders, prevented the channel's utilization. Federal Communications Commission policy allowed Denton's educators more time to raise money for a Denton station. Other conclusions suggest that the channel not be reassigned and that it be activated.

The objective of this dissertation is to propose the cross-layer spectrum management architecture for white space applications that improves the performance the main functions of the spectrum management. In the proposed cross-layer architecture, white space network devices such as white space devices and the spectrum map server cooperate to support the extended spectrum map, the inter-cell transmit power adaptation (ITPA), and the frequency-domain coexistence beacon (FCB). Upon the cross-layer architecture, firstly, white space devices (WSDs) achieve a faster search and higher accuracy in spectrum sensing with the extended spectrum map, the extended DHCP (Dynamic Host Configuration Protocol), and the FCB. Secondly, WSDs achieve the precise selection of their operating channel in spectrum decision with the extended spectrum map and the ITPA. In spectrum sharing, thirdly, the collaboration- based spectrum sharing with the ITPA achieve more accommodation of WSDs by increasing the number of channels shared between WSDs. Finally, WSDs with the FCB and the extended spectrum achieve effective spectrum mobility by obtaining the occupancy-status of channels precisely.
