Abstract
Provided are a system and method for coordinating dual wireless communications protocols when implementing a time difference of arrival framework for ranging between nodes. A first of the protocols (e.g., BLE) can be used to initiate synchronization and measurement staging, while ensuing calculations according to such synchronization and measurement can be conducted according a second of the protocols (e.g., UWB). In these regards, transitioning between the aforementioned protocols can result in a conservation of air time involved in an entirety of TDOA processes, and thus a conservation of energy.
