46、r radio equipment used in the Private (Dispatch) Land Mobile Services that employ Scalable Adaptive Modulation (SAM), for transmission and reception of data using digital techniques, with or without encryption, with a frequency of 1 GHz or less. The definition and description of the system in which
47、this equipment operates is given in the document TIA-902-A 1 The TIA Wideband Air Interface standard TIA-902.BAAA 2 defines the requirements of both the Physical Layer and the Data Link Layer in the OSI reference model for the radio interface in which this equipment operates. Use of this standard is
48、 encouraged for any application of similar equipment with Scalable Adaptive Modulation and may be applicable to equipment other than those listed above. However, this standard is not intended to cover transceiver equipment employing any or all modulation types or access methods. Therefore, the appli
49、cability of this document to digital transceiver equipment other than that called out in the scope must be carefully examined. 1.2 Object The object of this standard is to standardize parameter titles, definitions, the test conditions, and the methods of measurement used to ascertain the performance of equipment within the scope of this standard, and to make possible a meaningful comparison of the results of measurements made by different observers and on different equipment. 1.3 References The following standards contain provisions that, through reference in this text, constitute
