A wireless ranging system includes a first wireless unit and a second wireless unit spaced therefrom. The first wireless unit may include a time-of-arrival (TOA) wireless transmitter, and a near-field electromagnetic (NFE) wireless transmitter having a settable operating frequency. The second wireless unit may include a TOA wireless receiver cooperating with the TOA wireless transmitter, a NFE wireless receiver cooperating with the NFE wireless transmitter, and a ranging processor cooperating with the TOA wireless receiver. The ranging processor may generate a range estimate between the first and second wireless units, and generate an estimated operating frequency for the NFE wireless transmitter based upon the range estimate. The ranging processor may also generate a range window for the TOA wireless receiver via the ranging processor cooperating with the NFE wireless receiver, and use the range window with the TOA wireless receiver to generate a range estimate between the first and second wireless units.
