Developing Spectrum Sharing Technique and Demonstrating its Application

STAR-H Corporation will apply its extensive experience in RF propagation and analysis to the problem of developing more efficient uses of the RF spectrum. The ultimate goal is to mine the ambient RF spectrum for idle frequencies with sufficient bandwidthto utilize for short-duration transmissions. Longer duration connectivity is achieved by stitching together idle bandwidth in real time using a Software Defined Radio. To develop the background to enable this technology, in Phase I we will develop modelsfor the statistical analysis and testing of spectrum sharing methodologies. From the information gained by this modeling, concepts for spectrum sharing will be more completely developed. The benefits of such a system are enormous. The ability to moveaway from rigid frequency allocations and adapt to immediate communications needs in the ambient RF environment will benefit both military and civilian users alike. Military users will gain more flexibility in deploying wireless networks in support of thewarfighter and the Objective Force. Such systems will be highly secure and jam resistant and can expand their bandwidth to accommodate almost any desired data rate. Civilian users will more efficiently use the limited RF spectrum with reducedinterference.
