statistics on whether the slip frequency limit is exceeded. The primary source of error could be in the clock flow (i.e. MSC to BSC to BTS, etc.). In many cases it is discovered that the accuracy of the PRC is unsatisfactory (against given standards for mobile networks). Typical outputs of link budget calculations, frequency plans and interference are shown in Tables 4 and 5, and Figure 3.29.
