Abstract
Coverage and usage-based limitations to a wireless communications network can be estimated by monitoring network performance during a periods in which the network is relatively busy and relatively non-busy. For example, differences in distributions of bit error rates for calls in such time periods can be used to assess whether network limitations are associated with reduced-coverage zones or are usage-based. Such estimates can be used to target specific network features that limit network performance.
