4、and ITU-R SM.1413; d) that administrations should maintain spectrum management data with an automated database management system; e) that many administrations have been successful in implementing an automated database management system in the development and maintenance of their national spectrum ma
5、nagement data; f) that computer programs which accomplish engineering analysis are described in the ITU Catalogue of Software for Radio Spectrum Management and have proven to be useful in national spectrum management; g) that a WinBASMS has been developed jointly by the experts of ITU-R and ITU-D fo
6、r developing countries for the fixed, mobile and broadcasting services and a single user; h) that an upgraded spectrum management system needs to be developed to effectively meet the new requirements of managing modern telecommunication systems with increased spectrum and more complex frequency assi
7、gnment, other spectrum management data requirements and other radio services according to recommended standards; j) that the World Telecommunication Development Conference (Istanbul, 2002) (WTDC-02) recommended that such spectrum management system should be developed within Programme 2, recommends 1
8、 that the engineering for an upgraded system should be developed jointly by the Telecommunication Development Bureau (BDT) and the BR; 2 that a system should be upgraded with the ultimate objective of using the program as critical building blocks to improve spectrum management for developing countri
9、es; 2 Rec. ITU-R SM.1604 3 that the user interface of the system should be in English, French, Spanish with an option to convert to other languages; 4 that the upgraded system should contain the features described in Annex 1; 5 that the upgraded software should be implemented jointly by the experts
10、of ITU-R and ITU-D; 6 that the development and the implementation of the system by the experts of ITU-R and ITU-D should be completed in the shortest possible time; 7 that the introduction of the system should include the necessary training. Annex 1 Upgraded WinBASMS 1 Background The BASMS and WinBA
11、SMS computer software programs for national spectrum management were developed jointly by ITU-R and ITU-D according to requirements specified in Recommendation ITU-R SM.1048. A group of ITU experts developed the computer specifications and supervised the creation and testing of the software programs
12、 by a contractor. Implementation of the first DOS version (BASMS) of the system was initiated in 1995; in 1997 the system was amended to be supported by a Windows platform and operated in three languages (WinBASMS). The purpose of the WinBASMS software is to give developing countries a tool to effic
13、iently and effectively manage the radio spectrum primary for broadcasting, fixed and mobile radio services and therefore to accelerate the development of wireless technology in the countries. The WinBASMS is designed for ease of use and maintenance by a single user. The WinBASMS can be used to suppo
14、rt most functional requirements defined in the ITU Handbook on National Spectrum Management. The WinBASMS software is presently distributed free of charge in English, French and Spanish (a version in Russian is also available on special request) through regional and area training seminars on the Win
15、BASMS. This training is organized by the BDT under the ITU/BDT Valletta Action Plan and within the framework of ITU/BDT technical assistance missions on frequency management and radiocommunication development. The limitations of the WinBASMS include the following: Simplified implementation of propag
16、ation models, particularly those given by Recommendation ITU-R P.1546. Simplified calculation procedures within the interference calculation process and the frequency assignment process. No inclusion of monitoring functions or a spectrum monitoring database. Omission of a multiple user networking ca
17、pability. Omission of a digital terrain database and associated operational programs. No security features. Rec. ITU-R SM.1604 3 2 Objectives The general objectives for an Upgraded WinBASMS (UWinBASMS) are given in the WTDC-02 and WTDC-98 Resolution 9 documents and should include: The establishment
18、of a computerized operational structure that enables the smooth execution of administrative tasks, frequency allocation, spectrum analysis and monitoring. A single user capability. Improved dynamic engineering modules. Extensive training from the ITU to identify the technical requirements, operation
19、al procedures and human resource requirements. 3 UWinBASMS key features The Upgraded WinBASMS software for spectrum management should include: Administrative function. This function will be implemented on a relational database management system that ensures the integrity and consistency of the admin
20、istrative data. It will provide user screens that perform all administrative tasks including, frequency application records, frequency assignment records, licensing records, interference records, frequency measurement records and spectrum fee records. The program will be available in English, French
21、, Spanish and Russian. Engineering analysis function. This function will provide enhanced analysis tools for developing proposed frequency assignment for users. It will also provide the capability to calculate interference between one or more transmitters and a victim receiver under user specified c
22、onditions. The spectrum management system will be able to be operated from a single computer. The program will be tested in both an alpha and beta test mode. Training for users through regional seminars on how to use the spectrum management software will be conducted by the BDT. A limited number of
23、countries may also require detailed assistance in setting up the spectrum management system and this assistance will be provided by the BDT. 4 UWinBASMS upgrade tasks The group of experts that developed WinBASMS have identified over thirty software modifications that should be made to the WinBASMS p
24、rogram to improve the functioning of the WinBASMS software. Many of the modifications came from suggestions from over fifty developing countries and the group of experts that developed the software. The developing country suggestions came from developing countries that attended the eight WinBASMS se
25、minars held by the BDT. In addition four modifications should be made that would improve: propagation loss prediction for interference problems; the development of a monitoring database that would allow effective exchange of assignment and measurement data; improvement of engineering calculation capability; the addition of an antenna database from an antenna manufacturer. All these modifications are relatively easy to make and will greatly improve the functioning of the WinBASMS.
