Abstract

A cellular system access monitor for monitoring and reporting information relating to the operation of cellular telephone systems. The monitor features a cellular telephone of current design, responding to the expanded spectrum of 832 channels. The cellular telephone communicates with a controller using a self-clocking data transmission scheme to improve the reporting and displaying of cellular system parameters, such as cellsite control-channel identification numbers and textual cellsite identification information. Additionally, the monitor employes a calibration feature for measuring and displaying accurately signal strength in decibels. System parameters are shown on a bit-mapped display.
