The time of arrival (ToA) and received signal strength (RSS) estimation errors are modelled based on channel measurements in a non‐line‐of‐sight indoor environment. It is found interesting that their errors are largely independent. Suboptimal hybrid ToA/RSS ranging estimators are derived in closed form based on the obtained error models, and shown to achieve near‐optimal performance. The performance of all the estimators improves as the bandwidth increases.
