Abstract
Methods and systems are provided for processing signal strength information from a radio frequency transmitter and for determining signal coverage for a wireless device. In one embodiment, the method includes receiving signal strength information indicating a power for the radio frequency transmitter at one or more first locations; receiving location information representing a geographic location for one or more second locations; dividing the received signal strength information into one or more subsets of signal strength information; determining, for each of the one or more subsets, a local mean such that the local mean represents an average for one of the one or more subsets; and estimating a location for the local mean based on the received location information.
Claims12
A method for processing signal strength information from a radio frequency transmitter comprising the steps of:
- receiving signal strength information indicating a power for the radio frequency transmitter at one or more first locations;
- receiving location information representing a geographic location for one or more second locations;
- dividing the received signal strength information into one or more subsets of signal strength information, such that the one or more subsets are determined based on a speed of a receiver of the received signal strength information and a corresponding distance associated with the speed;
- determining, for each of the one or more subsets, a local mean, such that the local mean represents an average for one of the one or more subsets;
- estimating a location for the local mean based on the received location information;
- determining at least one distance between the estimated location and another estimated location based on the speed of the receiver and the signal strength information.
A method for processing signal strength information from a radio frequency transmitter comprising the steps of:
- receiving signal strength information indicating a power for the radio frequency transmitter at one or more first locations, wherein the signal strength information includes a set of signal strength data based on a signal trace;
- receiving location information representing a geographic location for one or more second locations, wherein the received location information for one or more second locations includes one or more of the following:
- a latitude, a longitude, or at least one of a plurality of first time stamps from a receiver of global positioning system information;
- attaching at least one of a plurality of second time stamps to the set of signal strength data;
- smoothing the plurality of second time stamps based on the plurality of first time stamps;
- dividing the received signal strength information into one or more subsets of signal strength information, such that the one or more subsets are determined based on a speed of a receiver of the received signal strength information;
- determining, for each of the one or more subsets, a local mean such that the local mean represents an average for one of the one or more subsets;
- estimating a location for the local mean based on the received location information.
