SIGNAL STRENGTH PROFILING
First Claim
Patent Images
1. A method, comprising:
- receiving wireless signals in an apparatus;
determining a signal strength for each received wireless signal;
accumulating an occurrence for each received wireless signal based on the determined signal strength in a histogram maintained within the apparatus;
identifying a source for each of the received wireless signals based on information in the received wireless signals; and
transmitting at least the source identification for each of the wireless signals along with information derived from the histogram to a mapping database,wherein the information derived from the histogram comprises maximum signal strength, minimum signal strength, median signal strength, mode signal strength, mean signal strength, and at least one of quartile and tertile signal strength ranges based on signal strength histogram probability mass.

Abstract
A system for supporting electronic positioning in apparatuses. Apparatuses may receive various wireless signals over time (800). The strength of the received wireless signals may be determined by the apparatuses (802), and based on this determination an occurrence for each received wireless signal may be accumulated in a histogram in the apparatus (804). Information based on the histogram may then be transmitted to a mapping database (810). The mapping database may then utilize this information to, for example, create signal-based maps for use in apparatus positioning.
