2、blications are designed to serve the public interest 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 particu
3、lar need. The existence of such Standards and Publications 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 volunta

By such action, TIA does not assume any liability to any patent owner, nor does it assume any obligation
5、 whatever to parties adopting the Standard or Publication. 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 t
6、o determine the applicability of regulatory limitations before its use.

The use or practice of contents of
8、 this Document may involve the use of intellectual property 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
9、to TIAs attention, a statement from the holder thereof is 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
10、licensing terms or conditions, which are instead left to the parties involved, nor will TIA opine or judge whether proposed licensing terms or conditions are reasonable or non-discriminatory.

WAI Packet Data Specification TIA-902.BAEB-A i Foreword (This foreword is not part of this standard.) This document has be
20、en published 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 Telecommu
21、nications Directors (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
22、document has 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 packet data bearer service technology. Generally, the wideband air interface has been de
23、veloped by TIA TR-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)”. T
24、his Packet Data Specification provides a standard for the definition and control for transmission of IP Datagrams over 50, 100, and 150 kHz bandwidth Wideband Air Interface lower layer protocols. The TIA makes no claims as to the applicability of the information contained in this document for any pu
25、rpose 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 has been i
26、nvested 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 document will
27、 be updated as necessary. TIA-902.BAEB-A WAI Packet Data 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 position i
28、s 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 applicants desiri
29、ng to obtain such licenses. The following 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 conducti
30、ng inquiries into the legal validity or scope of those patents that are brought to its attention. WAI Packet Data Specification TIA-902.BAEB-A iii TABLE OF CONTENTS 1. SCOPE1 2. TERMS.2 3.
