43、nt used in the Private (Dispatch) Land Mobile Services that employ Isotropic Orthogonal Transform Algorithm modulation (IOTA), 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
44、in which this equipment operates is given in the document TIA-902-A 1 The TIA Wideband Air Interface standard (IOTA) TIA-902.BBAB 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
45、this standard is encouraged for any application of similar equipment with IOTA 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 ap
46、plicability 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 performa
47、nce 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 provision
48、s of this standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards published by them. 1 (Informa
