¿µ¹® ³»¿ë¿ä¾à This Report focuses on the applications of CRSs in the land mobile service. It provides a detailed description of CRS capabilities and enabling. It describes also the key technical features related to these technologies as enablers for enhanced sharing and coexistence as well as more efficient use of resources. The report describes the high level characteristics, operational and technical requirements of CRS. Also, general performance criteria and metrics are presented in this report to help the performance evaluation of land mobile system employing CRS technology. Furthermore, factors related to the introduction of CRS technologies are discussed in addition to related migration issues.
