23、BAAA-B i Foreword (This foreword is not part of this document.) This document has been created in response to a request by the Project 25 Steering Committee as provided for in a Memorandum of Understanding (MOU) dated April 1992 and amended December 1993. The MOU states that the Project 25 Steering

24、Committee shall devise a Common System Standard for digital public safety communications (the Standard) commonly referred to as Project 25 or P25, and that TIA, as agreed to by the membership of the appropriate TIA Engineering Committee, will provide technical assistance in the development of docume

25、ntation for the Standard. If the abbreviation “P25” or the wording “Project 25” appears on the cover sheet of this document when published that indicates the Project 25 Steering Committee has adopted this document as part of the Standard. The appearance of the abbreviation “P25” or the wording “Proj

26、ect 25” on the cover sheet of this document or in the title of any document referenced herein should not be interpreted as limiting the applicability of the information contained in any document to “P25” or “Project 25” implementations exclusively. This document was developed by the TIA TR-8.15 Comm

27、on Air Interface Subcommittee and provides a specification of the FDMA Common Air Interface for TIA-102 Land Mobile Radio systems. This document describes the access method, modulation, data rate, and message formats necessary to ensure a common air interface. The 3rdedition (Revision B) of this doc

28、ument revised TIA-102.BAAA-A to address errata comments and align the content with current TR-8 practices. This document cancels and replaces TIA-102.BAAA-A. There is one annex in this document. Annex A is normative and is considered part of this specification. TIA does not evaluate, test, verify or

29、 investigate the information, accuracy, soundness, or credibility of the contents of the Document. In Publishing the Document, TIA disclaims any undertaking to perform any duty owed to or for anyone. Some aspects of the specifications contained in this document may not have been fully operationally

30、tested; however, a great deal of time and good faith effort has been invested in the preparation of this document to ensure the accuracy of the information it contains. TIA-102.BAAA-B ii Patent Identification The readers attention is called to the possibility that compliance with this document may r

31、equire the use of one or more inventions covered by patent rights. By publication of this document, no position is taken with respect to the validity of those claims or any patent rights in connection therewith. The patent holders so far identified have, we believe, filed statements of willingness t

32、o grant licenses under those rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such licenses. The following patent holders and patents have been identified in accordance with the TIA intellectual property rights policy: No patents have been identified T

33、IA shall not be responsible for identifying patents for which licenses may be required by this document or for conducting inquiries into the legal validity or scope of those patents that are brought to its attention.
