This Standard was prepared by TIA Working Group TG-8.11.3 and has been approved
26、by Subcommittee TR-8.11. Members of TR-45 have also reviewed and made comments on this document as it impacts antenna usage in the Cellular and PCS Industries. National Spectrum Managers Association (NSMA) contributed to the preparation of this document. Many of the requirements contained in this do
27、cument are compatible with those of NSMA Recommendation WG16.99.050 dated 5/20/99. However, caution is advised because differences may exist between the two documents. Annexes A and B are normative. Annex C is for information only. This is Revision B of this Standard and supersedes TIA -804-A. Copyr

29、e 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 therewith. The patent holders so far identified have, we believe, filed statements of willingness to grant li
30、censes 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 in accordance with the TIA intellectual property rights policy: - None identified TIA is not responsible fo

32、tion or networking permitted without license from IHS-,-,-TIA-804-B 1INTRODUCTION This standard is intended to provide a standard format for manufacturers of antennas for the Terrestrial Land Mobile Radio industry to adhere to. It was motivated by the observation by propagation software providers (i
33、.e. users of such patterns) that many manufacturers have proprietary formats and that a single standardized format would make software development simpler, assure consistent usage of antenna pattern data, and facilitate data accuracy through a robust, common data format. This format is year 2000 com
34、pliant. . Terrestrial Land Mobile Radio - Antenna Systems - Standard Format for Digitized Antenna Patterns 1.0 Scope This document is intended to standardize the presentation of digitized antenna patterns for antenna systems in the Terrestrial Land Mobile Radio Services. 2.0 References The following
35、 documents should be consulted when applying this Standard: 1 EIA/TIA-329-C, Minimum Standards for Communication Antennas, Part 1: Base Station Antennas 3.0 Requirements 3.1 Overall Format Each file consists of data for one antenna operating at one or more frequencies. Each frequency consists of one
36、 or more pattern cuts. Each pattern cut consists of a number of data points. Only those fields marked with an “n“, or “x“ are required to be compliant to this standard; however, manufacturers are strongly encouraged to include all fields in their data files. Data shall be entered into the file in th
37、e order given in this standard. It is not necessary, however, to include “empty fields”. The format of the data that makes up the fields shall be ASCII text.

38、without license from IHS-,-,-TIA-804-B 23.2 Fields 3.2.1 Field Characteristics The fields to be used in digitized antenna patterns for the Terrestrial Land Mobile Radio Services are defined in Table 1. They are described in detail in subclause 3.2.2. All data positions up to and including the decima
39、l point (if appropriate for the data type) must be filled. The comma (“,”) serves as a data item delimiter. Per-line comments may be added to any record. In any record, all data after a “!” character will be ignored. The length of the field specified is the maximum allowable length of the record. If
40、 the format is free form, then the record may be shorter than the maximum length, and terminated with a carriage return and line feed characters.
