Abstract
Systems and methods of locating missing endpoints in a utility meter network include periodically receiving electronic GPS data including coordinates identifying the physical location of a mobile meter reading device and collecting radio frequency (RF) data transmissions sent by one or more missing endpoints in proximity to the mobile meter reading device. Energy levels associated with the RF data transmissions can be used to determine a signal strength indicator for each transmission. The transmissions are collected while the mobile meter reading device is positioned in at least first and second different locations relative to each missing endpoint. A triangulation procedure is electronically implemented using the GPS coordinates and the signal strength indicator for a given missing endpoint as determined in the at least first and second different locations in order to identify an estimated location for the given missing endpoint, which is provided as electronic output to a user.
