TIA-902.CAAB Foreword This foreword is not part of this standard. This document was prepared by the TR 8.6 Performance Standards subcommittee. It was approved f
20、or ballot at the committee meeting held on October 7, 2002 and approved for publication on January 13,2003. It is one member of the TIA-902 family of standards based on Scalable Adaptive Modulation (SAM) technology for transmission of high speed digital data signals on RF channels of bandwidth 50, 1
21、00 or 150 kHz such as those assigned in the 767-773/797-803 MHz paired frequency band assigned in the United States exclusively for Public Safety use. There are two Annexes in this standard, both of which are informative and are not considered as part of this standard. iTIA-902.CAAB Patent Identific
22、ation 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 those claims or any patent rights in connection the
23、rewith. 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 patent holders and patents have been identified i

37、oy Scalable Adaptive Modulation (SAM), for transmission and reception of data using digital techniques, with or without encryption, with a frequency of 1 GHz or less. The definition and description of the system in which this equipment operates is given in the document (TIA/EIA-902-A). The TIA Wide
38、Air Interface standard (TIA/EIA-902.BAAA) defines the requirements of both the Physical Layer and the Data Link Layer in the OSI reference model for the radio interface in which this equipment operates. Use of this standard is encouraged for any application of similar equipment with SAM modulation,
39、and may be applicable to equipment other than those listed above. However, this standard is not intended to cover transceiver equipment employing any or all modulation types or access methods. Therefore, the applicability of this document to digital transceiver equipment other than that called out i
40、n the scope must be carefully examined. 1.2 Object The object of this document is to serve as a performance level benchmark for assessing interoperable digitally modulated radio equipment compliant with TIA/EIA- 902.BAAA using measurement methods defined in companion document TIA/EIA- 902.CAAA, and
41、selected federal standards as noted in clause 1.3 herein. 1.3 References The following standards contain provisions that, through reference in this text, constitute provisions of this standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and
42、parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards published by them. 1 TSB-902.A Digital Radio Technical Standards - Public Safety Wideband Data Standards Project - Wideband Data System and Standards Defin
