SJ/T 10597-1994移動通信術(shù)語

本標準規(guī)定了移動通信所用的基本術(shù)語及其定義，包括移動通信業(yè)務、基本技術(shù)、移動通信系統(tǒng)及各類移動通信設備涉及的術(shù)語及定義等。本標準適用于移動通信的科研、教學、設計、生產(chǎn)、使用和管理。

ITU-R INFORME F.2087 SPANISH-2006高頻固定無線通信系統(tǒng)的要求

Increasing requirements in the HF fixed and mobile services are driven by two factors. Firstly, other technologies do not meet all requirements. This is especially true in publicprotection and disaster relief operations. Ease of deployment and comparatively lower costs continue to make HF fixed and mobile applications desirable duringthe development of a crisis situation. The second factor is the emergence of HF advanced technologies which allow development of applications to exchange more information at higher data rates.

ITU-R M.1651-2003包括使用5 GHz頻帶的無線局域網(wǎng)寬帶漫游無線接入系統(tǒng)的必需頻譜的評估方法.關(guān)于ITU-R 212/8和ITU-R 142/9

This Recommendation provides a method for assessing the required spectrum for broadband nomadic wireless access (NWA) systems including radio local area networks (RLANs).

ITU-R RAPPORT SM.2130 FRENCH-2008無線電臺的檢查

This Report presents an overview of Inspections Procedures in response to Question ITU-R 225/1 regarding inspection techniques and procedures. The Question relates to how administrations proceed in planning and conducting radio station inspections. The purpose of this Report is to provide general guidelines for planning and performing inspection activities on various types of radio stations. Inspection activities often include review and verification of both technical and administrative conditions assigned to a radio station or other spectrum user. Although the term “l(fā)icensed” is used throughout the document, this term can be considered here to include not only stations with licences issued by the regulatory authority, but also other authorized spectrum users (such as those operating with “l(fā)icence exempt” devices like low-power radios and RF devices operating under equipment standards approval). The primary focus of this report is to consider inspections that are conducted “on-site”, by visiting the transmitter location. Included in Annexes are some specific examples in certain services, toprovide examples of howthe general guidelines can be applied. This Report should be considered a general guidance document for inspections planning.

ITU-R REPORT F.2047-2004固定業(yè)務的技術(shù)發(fā)展和應用趨勢

This Report addresses the following items in relation to the future development of the FS: FS technology trends overview; development of the role of FS systems in telecommunication networks; FS band usage trends in some countries; frequency sharing studies with other services; possible future applications in the FS.

ITU-R REPORT M.2014-1-2006用于調(diào)度業(yè)務的地面數(shù)字移動系統(tǒng)

Demand in the land mobile service is on the increase due to annual growth as well as to new data-based service requirements. This has led to the development of more spectrally efficient technologies utilizing digital modulation and in many cases trunking. These technologies are being introduced in systems worldwide to accommodate this demand.

ITU-R REPORT M.2033-2003公眾保護和減災無線電通信目標和要求

The purpose of the Report is to define the public protection and disaster relief (PPDR) objectivesand requirements for the implementation of future advanced solutions to satisfy the operationalneeds of PPDR organizations around the year 2010. Specifically, it identifies objectives, applications, requirements, a methodology for spectrum calculations, spectrum requirements and solutionsfor interoperability

ITU-R REPORT M.2084-2006自動識別系統(tǒng)信息的衛(wèi)星探測

In the early 1990s, the International Association of Maritime Aids to Navigation and Lighthouse Authorities (IALA) first proposed the development of a universal shipborne system to improve the maritime safety and efficiency of navigation, and to help protect the marine environment. Subsequent to that proposal, the International Maritime Organization (IMO), the ITU, and the International Electrotechnical Commission (IEC) adopted a new navigation system now known as the Automatic Identification System (AIS) to help achieve these goals. The primary purpose of the AIS is to facilitate the efficient exchange of navigational data between ships and between ships and shore stations to significantly improve safety of navigation and promote improved control and monitoring of maritime events. The technical characteristics of the current AIS system using time division multiple access (TDMA) techniques in the VHF maritime mobile band are described in detail in Recommendation ITU-R M.1371.

ITU-R REPORT M.2110-2007在450-470 MHz頻段的無線電通信業(yè)務和IMT系統(tǒng)運行之間的共享研究

ITU-R conducted sharing studies related to the candidate bands to determine the suitability of the candidate bands for IMT identification. This Report assesses the feasibility of sharing between IMT systems operating in the 450-470 MHz band and the radiocommunication services having a primary allocation in Section IV of Article 5 of the Radio Regulations – Table ofFrequency Allocations (henceforth referred to simply as the Table) in the 450-470 MHz band and in the adjacent 420-450 MHz and 470-480 MHz bands. This study addresses onemember of the IMT family, i.e. IMT-2000 CDMA Multi-Carrier (CDMA-MC).For ease of reference, CDMA-MC operating in the 450-470 MHz range is referred to as CDMA450 throughout the document. Further revisions of this Report may include other technologies in the IMT family.
