scope:

This standard provides definition and methods of measurement standards for radio equipment 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 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 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 applicability of this document to digital transceiver equipment other than that called out in the scope must be carefully examined.
