1. A system comprising:
a plurality of ultra-wide band (UWB) modules located within a vehicle having a plurality of module locations, the plurality of module locations being located at known distances relative to each other, each UWB module being configured to perform UWB distance ranging with a portable device and with every other UWB module of the plurality of UWB modules;
a control module in communication with the plurality of UWB modules and having a processor and memory configured to:
store the known distances of the plurality of module locations relative to each other;
instruct each UWB module of the plurality of UWB modules to perform distance ranging with every other UWB module of the plurality of UWB modules;
receive a set of measurements associated with each UWB module of the plurality of UWB modules, the set of measurements including distances measured by the associated UWB module to every other UWB module of the plurality of UWB modules;
perform a comparison of the set of measurements associated with each UWB module with the known distances of the plurality of UWB modules relative to each other;
determine a location within the vehicle of each UWB module of the plurality of UWB modules based on the comparison, the location for each UWB module being one of the plurality of module locations; and
assign a unique network address to each UWB module of the plurality of UWB modules.
