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