Note:  System Coverage maps are based on 95% analog predicted coverage. Motorola's contract with South Carolina requires that system coverage maps be depicted with 95% analog predicted coverage reliability. Areas shown in white on the coverage maps may still have radio coverage but the predicted reliability is below 95%.

No radio system coverage can be 100% reliable, there will always be particular times and locations where signal strength is below that needed for satisfactory performance.

What does 95% predicted coverage mean - Reliability of signal strength is given in percentage within the coverage area predicted. Shaded areas within the maps are predicted to have 95% coverage reliability. This means that if the area is divided uniformly into 100 locations then 95 of these locations will provide satisfactory coverage and 5 of these locations may provide unsatisfactory coverage. In an actual verification of satisfactory coverage performance the test must be based on a large number of locations consistent with good statistical practice.
