WAI MAC/RLA Layer Specification TIA-902.BAAC-A i Foreword (This foreword is not part of this standard.) This document has been published
20、by the Telecommunications Industry Association (TIA) in accordance with the terms and conditions provided for in a Memorandum of Understanding (MoU) executed by and between the TIA, the Associated Public-Safety Communications Officials (APCO), the National Association of State Telecommunications Dir
21、ectors (NASTD), and the various agencies of the Federal government (FED). This TIA Standard is being promulgated and will be maintained by the TR-8.5 Signaling and Data Transmission committee, and working groups under the sponsorship of the Telecommunications Industry Association. This document has
22、been published as a TIA Standard because it contains useful technical information on emerging digital techniques for Land Mobile Radio Service. In particular, it describes the wideband air interface media access control layer technology. Generally, the wideband air interface been developed by TIA TR
23、-8.5 to be consistent with the Statement of Requirements adopted by the National Coordination Committees Interoperability Subcommittee, WG6 Wideband Data. This document references that the primary user needs document will be “APCO Project 25/34 Statement of Requirements (P34SOR)”. This media access
24、control / radio link adaptation layer specification provides a standard for the definition and control transmission high-speed digital information over 50, 100, and 150 kHz bandwidth physical radio media. The TIA makes no claims as to the applicability of the information contained in this document f
25、or any purpose although it is believed that the information will prove to be invaluable to designers of wideband data compliant equipment. Some aspects of the specifications contained in this document may not have been fully operationally tested; however, a great deal of time and good faith effort h
26、as been invested in the preparation of this document to ensure the accuracy of the information it contains. While all reasonable efforts have been made to ensure the accuracy of this document, it should be understood that significant work remains in fully developing the standard series and this docu
27、ment will be updated as necessary. TIA-902.BAAC-A WAI MAC/RLA Layer Specification ii Patent Identification The readers attention is called to the possibility that compliance with this document may require the use of one or more inventions covered by patent rights. By publication of this document, no
28、 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 to grant licenses under those rights on reasonable and nondiscriminatory terms and conditions to applic
29、ants desiring to obtain such licenses. The following patent holders and patents have been identified in accordance with the TIA intellectual property rights policy: Motorola US 5,185,796; Encryption Synchronization Combined with Encryption Key Identification Motorola US 5,559,807; Power Amplifier Li
30、nearization in a TDMA Mobile Radio System TIA 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.
