Abstract
Abstract A method and system for designing a cell for a Code Division Multiple Access (CDMA) communication system and the like. The method includes measuring error rate as a function of signal level at a selected radio frequency, and determining a signal level corresponding to a selected error rate based on the measurements of error rate as a function of signal level. The method also includes determining a coverage area based on the signal level determined and a voice quality factor. The system includes input and output devices, a processor, memory and software for performing the method.
