Orange RaCE Test Report <br />1.0 Introduction <br />Radio system coverage conformance testing is defined by three performance criteria: <br />channel performance criterion (CPC), service area definition with conditions, and the <br />validated service area reliability. <br />The RaCE test set was designed by CTA to measure end -to -end radio system coverage <br />performance. The RaCE test set can be utilized for conformance testing. It can also be <br />used to test and evaluate other system coverage performance characteristics. The <br />RaCE test set consists of two units: a stationary unit and a mobile unit. The combination <br />of these units allows sequential testing of both RF uplink and downlink communication <br />paths. The RaCE test set is capable of testing the entire RF communication path, <br />measuring the talk -out signal strength of the control and working channels, and directly <br />measuring the delivered audio quality (DAQ) of both the talk -out and talk -in RF path. <br />1.1 Purpose <br />Orange County Emergency Services in Orange County, North Carolina tasked CTA to <br />conduct an evaluation of the radio coverage provide by the State's Voice Interoperability <br />Plan for Emergency Responders (VIPER) network within their service area. <br />There were two specific goals of this testing: <br />• To determine the DAQ (Delivered Audio Quality) the VIPER radio system can provide <br />to Orange County Emergency Services. <br />• To gather signal strength (control channel) data from the seven VIPER sites most <br />likely to provide service to Orange county. <br />
