  Location information is often used as a proxy to infer the performance of a
wireless communication link. Using a very simple model, this letter unveils a
basic statistical relation between the location estimation uncertainty and
wireless link reliability. First, a Cram\'er-Rao bound for the localization
error is derived. Then, wireless link reliability is characterized by how
likely the outage probability is to be above a target threshold. We show that
the reliability is sensitive to location errors, especially when the channel
statistics are also sensitive to the location. Finally, we highlight the
difficulty of choosing a rate that meets target reliability while accounting
for the location uncertainty.
