A system and method for using a physical layer device to locate a thermal signature in a cable plant for diagnostic, enhanced, and higher power applications. A second coil element includes a third loop-shaped conductor and a fourth loop-shaped conductor. The solar kiosk includes a multiplicity of solar panels. Prior to delivery, the optimized treatment plan is analyzed to determine whether a quality of the optimized treatment plan is acceptable. Content may be gathered based on aggregated geo-fencing area comprising the plurality of first geo-fencing areas and the one or more second geo-fencing areas. These phase and magnitude differences, having a relationship to analyte concentration, are measured, correlated and processed to determine analyte concentration in the material sample.
