Systems, methods, and devices for combining narrowband and ultra-wideband (UWB) communication to provide enhanced ranging are disclosed. In an exemplary aspect, a method of ranging is disclosed. In some embodiments, the method includes generating a coarse distance estimate using narrowband communications. The method may further include generating a channel impulse response (CIR) estimate using UWB communications; and estimating a distance between a first device and a second device based on the coarse distance estimate and the CIR estimate.
