Abstract: The disclosed embodiments describe an automatic, adaptive system and method for efficiently and effectively scheduling advertising spots in commercial break locations across various networks, zones, channels, dates, times, and specific products, for example. The disclosed embodiments make use of fixed and relative factors, that may be user-defined, which assign a “cost” to one or more particular breaks which thereby allow for quick and accurate scheduling of spots. The “costs” may represent a value, or desirability, of a break for the advertiser and may be a function of both the fixed and relative factors. The fixed and relative factors may be configurable and may change for different advertising clients, different contract lines, different networks, different spot placement, etc. The placement of spots may be accomplished through the use of an ordered list which may be generated based on a number of inputs that may be user-selected.

Abstract: A method of modifying calibration data used to geo-locate a mobile station located in an indoor environment is disclosed. When a mobile station is located indoors, the signal strength of signals received and/or transmitted by the mobile station have the tendency to be lower than the strength of the signals received by a mobile station located outdoors. As a result of these lower signal strengths, geo-location efforts which rely on signal strengths may result in unsatisfactory location accuracy. Modifying pre-existing calibration data obtained outdoors may provide a way to simulate indoor calibration data characteristics.
