Wideband Data System and Standards Definition TSB-902.AiForeword(This foreword is not part of this bulletin.)This document has been published by the Telecommunic
20、ations IndustriesAssociation (TIA) in accordance with the terms and conditions provided for in aMemorandum of Understanding (MoU) executed by and between the TIA, theAssociated Public-Safety Communications Officials (APCO), the NationalAssociation of State Telecommunications Directors (NASTD), and t
21、he variousagencies of the Federal government (FED).This Telecommunications Systems Bulletin is being promulgated and will bemaintained by the TR-8 Private Radio Technical Standards committee, responsiblesubcommittees, and working groups under the sponsorship of theTelecommunications Industry Associa
22、tion. This document has been published as aTelecommunications Systems Bulletin because it contains useful technicalinformation on emerging digital techniques for Land Mobile Radio Service. Inparticular, it describes the wideband data system and services that currently may beperformed by communicatio
23、ns equipment conforming to this standard.Generally, the Wideband Data System and Standards Definition have beendeveloped by TIA TR-8.5 to be consistent with the Statement of Requirementsadopted by the National Coordination Committees Interoperability Subcommittee,WG6 Wideband Data. This document ref
24、erences that the primary user needsdocument will be “APCO Project 25/34 Statement of Requirements (P34SOR)”.This TSB provides a highlight of the user requirements, a description of user packetdata services, identifies the system configurations and references models, anddefines the overall structure
25、of the Wideband Data Standards Series. It includes aninformative annex describing the general Internet Architecture because it will beused as the baseline system model to aid in the convergence and interoperation ofwired and wireless networks.The TIA makes no claims as to the applicability of the in
26、formation contained in thisdocument for any purpose although it is believed that the information will prove to beinvaluable to designers of wideband data compliant equipment. Some aspects ofthe specifications contained in this document may not have been fully operationallytested; however, a great de
27、al of time and good faith effort has been invested in thepreparation of this document to ensure the accuracy of the information it contains.While all reasonable efforts have been made to ensure the accuracy of thisdocument, it should be understood that significant work remains in fully developingthe
28、 standard series and this document will be updated as necessary.TSB-902.A Wideband Data System and Standards DefinitioniiPatent IdentificationThe readers attention is called to the possibility that compliance with this documentmay require the use of one or more inventions covered by patent rights.By
29、 publication of this document no position is taken with respect to the validity ofthose claims or any patent rights in connection therewith. The patent holders so faridentified have, we believe, filed statements of willingness to grant licenses underthose rights on reasonable and nondiscriminatory t
30、erms and conditions toapplicants desiring to obtain such licenses.The following patent holders and patents have been identified in accordance withthe TIA intellectual property rights policy: No patents are currently identifiedTIA shall not be responsible for identifying patents for which licenses ma
31、y berequired by this document or for conducting inquiries into the legal validity orscope of those patents that are brought to its attention.Wideband Data System and Standards Definition TSB-902.AiiiTABLE OF CONTENTS1.

Wideband Data System RequirementsThis section describes several high level interoperability and technologyrequirements. The detailed list of user r
42、equirements and technical issues have beenprovided by the FCCs NCC and has additionally used applicable parts of theAPCO Project 34 Statement of Requirements. The following detailed userrequirements documents are referenced: Federal Communications Commissions, National Coordination Committees(NCCs),
43、 Interoperability Subcommittees, WG 6, Wideband Data, User NeedsStatement of Requirements (SOR), approved version APCO Project 25/34 New Technology Standards Project, Statement ofRequirements (SOR), version 4.03.1 InteroperabilityThe first major NCC requirement is to insure that all wideband data ra
44、dios from anyagency shall communicate on the interoperability channels with all other widebandradios. The vision is to maximize fast and efficient high-speed data interoperabilityamong public safety agencies in the 700 MHz band.3.1.1 System and Equipment InteroperabilityThe following definitions are
45、 used to define the difference between interoperabilityand interworking.3.1.1.1 Direct Subscriber Unit InteroperabilityThe ability for a subscriber unit from vendor “A“ to use a defined set of standardfeatures when operating with a subscriber unit from vendor “B“. Proper systemadministrator subscrib

This may be provided bysystem administrator commissioning or automatically throug
47、h system interworkingfunctions.3.1.1.3 System InterworkingThe ability for infrastructures from two different vendors to provide a defined set ofstandard services to subscriber units that spans the domain of one, or bothsystems.3.1.2 Packet Data ConnectivityIt is important to note that the industry h

49、System and Standards Definition4requirement; it is necessary that the radios support only a single standard packetinterface. The TIA-102 series specifies Internet Protocol version 4 as the packetdata bearer service; and support of this connectivity fosters interoperability withnarrowband data systems.3.2 Channel BandwidthsThe second major NCC requirement is to support and describe operations in thethree wideband channels bandwidths of 50 kHz, 100 kHz, and 150 kHz, asspecified by FCC WT Docket 96-86. This requirement additionally supports APCOProject 34s desire for a standard
