TIA-902.CBAB iiiForeword This foreword is not part of this standard. This document was prepared by the TR 8.6 Performance Standards subcommittee.
20、 It is one member of the TIA-902 family of standards based on Isotopic Orthogonal Transform Algorithm (IOTA) technology for transmission of high speed digital data signals on RF channels of bandwidth 50, 100 or 150 kHz. There are two Annexes in this standard, both of which are informative and are no
21、t considered as part of this standard. NOTE: The users attention is called to the possibility that compliance with this document may require use of one or more inventions covered by patent rights. By publication of this TIA Publication, no position is taken with respect to the validity of those clai
22、ms of rights or of any patent rights in connection with this document. The patent holder(s) so far identified to TIA have, however, filed statements of willingness to grant licenses under those rights either without compensation or on reasonable and nondiscriminatory terms and conditions to applican
23、ts desiring to obtain such licenses for the purpose of implementing this TIA Publication. Details regarding the filed statements may be obtained from the TIA. TIA shall not be responsible for identifying patents for which licenses may be required in connection with any TIA Publication or for conduct
24、ing inquiries into the legal validity or scope of those patents that are brought to its attention.

37、tion 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-902-A). The TIA Wide Air Interface standard (TIA-902.BBAA) defines the requirements of bot
38、h 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 IOTA modulation, and may be applicable to equipment other than those listed above. Howeve
39、r, 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 in the scope must be carefully examined. 1.2 Object The object of this do
40、cument is to serve as a performance level benchmark for assessing interoperable digitally modulated radio equipment compliant with TIA- 902.BBAB using measurement methods defined in companion document TIA- 902.CBAA, and selected federal standards as noted in clause 1.3 herein. 1.3 References The fol
