2、 through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for their particular need. The existence of such Standards and Public

3、ations shall not in any respect preclude any member or non-member of TIA from manufacturing or selling products not conforming to such Standards and Publications. Neither shall the existence of such Standards and Publications preclude their voluntary use by Non-TIA members, either domestically or in

4、ternationally. Standards and Publications are adopted by TIA in accordance with the American National Standards Institute (ANSI) patent policy. By such action, TIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Public

5、ation. This Standard does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of this Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitati

6、ons before its use. (From Project No. PN-3-0182-RF1, formulated under the cognizance of the TR-8 Mobile and Personal Private and Radio Standards. TR-8.5 Subcommittee on Signaling and Data Transmission). Published by TELECOMMUNICATIONS INDUSTRY ASSOCIATION Technology (b) there is no assurance that th

7、e Document will be approved by any Committee of TIA or any other body in its present or any other form; (c) the Document may be amended, modified or changed in the standards development or any editing process. The use or practice of contents of this Document may involve the use of intellectual prope

8、rty rights (“IPR”), including pending or issued patents, or copyrights, owned by one or more parties. TIA makes no search or investigation for IPR. When IPR consisting of patents and published pending patent applications are claimed and called to TIAs attention, a statement from the holder thereof i

9、s requested, all in accordance with the Manual. TIA takes no position with reference to, and disclaims any obligation to investigate or inquire into, the scope or validity of any claims of IPR. TIA will neither be a party to discussions of any licensing terms or conditions, which are instead left to

10、 the parties involved, nor will TIA opine or judge whether proposed licensing terms or conditions are reasonable or non-discriminatory. TIA does not warrant or represent that procedures or practices suggested or provided in the Manual have been complied with as respects the Document or its contents.

11、 If the Document contains one or more Normative References to a document published by another organization (“other SSO”) engaged in the formulation, development or publication of standards (whether designated as a standard, specification, recommendation or otherwise), whether such reference consists

12、 of mandatory, alternate or optional elements (as defined in the TIA Engineering Manual, 4thedition) then (i) TIA disclaims any duty or obligation to search or investigate the records of any other SSO for IPR or letters of assurance relating to any such Normative Reference; (ii) TIAs policy of encou

13、ragement of voluntary disclosure (see Engineering Manual Section 6.5.1) of Essential Patent(s) and published pending patent applications shall apply; and (iii) Information as to claims of IPR in the records or publications of the other SSO shall not constitute identification to TIA of a claim of Ess

14、ential Patent(s) or published pending patent applications. TIA does not enforce or monitor compliance with the contents of the Document. TIA does not certify, inspect, test or otherwise investigate products, designs or services or any claims of compliance with the contents of the Document. ALL WARRA

WAI Overview TSB-902.BAAA i Foreword (This foreword is not part of this standard.) This document has been published by the Telecommunications Industry Association (TIA) in accord

20、ance 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 Directors (NASTD), and the various agencies of the Federal govern

21、ment (FED). This Telecommunications System Bulletin (TSB) is being promulgated and 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 been published as a TSB because it contain

22、s useful technical information on emerging digital techniques for Land Mobile Radio Service. In particular, it generally describes the wideband air interface. Generally, the wideband air interface has been developed by TIA TR-8.5 to be consistent with the Statement of Requirements adopted by the Nat

23、ional Coordination Committees Interoperability Subcommittee, WG6 Wideband Data. This document references that the primary user needs document is the “APCO Project 25/34 Statement of Requirements (P34SOR)”. This Wideband Air Interface Overview provides a general description and framework for the WAI

24、protocol communications stack. A protocol layer model using primitive interfaces is also presented to aid the reader in understanding the functionality of each protocol layer. The TIA makes no claims as to the applicability of the information contained in this document for any purpose although it is

25、 believed that the information may 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 has been invested in the prepar

26、ation 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 document may be updated as necessa

27、ry. TSB-902.BAAA WAI Overview 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 position is taken with respect to the validity of th

28、ose 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 applicants desiring to obtain such licenses. The following

29、patent holders and patents have been identified in accordance with the TIA intellectual property rights policy: None currently identified 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 sc

30、ope of those patents that are brought to its attention. WAI Overview TSB-902.BAAA iii TABLE OF CONTENTS 1. SCOPE1 2. TERMS.3 3.
