Link: Predicting Coverage Performance
Coverage reliability is possibly the single most critical requirement for public-safety communications. It’s also one of the most complex. Effective coverage takes a deep understanding of coverage theory, a toolbox of principles and approaches, and the practical experience of successful implementations.
Coverage reliability is an engineer’s way of stating the probability that public-safety officers can communicate clearly, at any time and any place within their coverage areas. Typically, radio network operators specify a service area reliability of 97 percent.
