1. A system comprising:
a memory; and
processing circuitry in communication with the memory and configured to:
determine a first location probability surface for a location of a wireless terminal for a current time interval, the first location probability surface representing a first plurality of probabilities that the wireless terminal is within a plurality of regions, each probability of the first plurality of probabilities corresponding to a different region of the plurality of regions;
determine, based at least in part on a second location probability surface for the location of the wireless terminal at a previous time interval, a motion probability surface for a motion of the wireless terminal, the motion probability surface representing a second plurality of probabilities associated with a plurality of motion estimates of the wireless terminal, each probability of the second plurality of probabilities associated with a different motion estimate of the plurality of motion estimates; and
estimate, based on the first location probability surface for the location of the wireless terminal and the motion probability surface for the motion of the wireless terminal, the location of the wireless terminal to be within a particular region of the plurality of regions.
