1、QUESTION ITU-R 93/6*Frequency requirements for electronic news gathering (1996-2004) The ITU Radiocommunication Assembly, considering a) that electronic news gathering (ENG) using portable or transportable equipment is used to support broadcast operations and provides a valuable method of transmissi

2、on for the rapid acquisition of news for broadcasting; b) that different frequency bands are currently used in different countries for ENG in the terrestrial, fixed and mobile service allocations; c) that the harmonization of the spectrum requirements for ENG would provide greater efficiencies in sp

3、ectrum usage and equipment interoperability; d) that such harmonization can only be achieved when the technical and operational characteristics of ENG links are investigated further; e) that the use of such links may give rise to sharing difficulties within these bands with existing services which m

4、ust be protected, decides that the following Question should be studied 1 What are the frequency requirements for ENG links? 2 What are the most suitable frequency bands for the operation of ENG links? 3 What are the technical and operational factors affecting the choice of frequency bands for ENG l

5、inks? 4 What sharing criteria should be recommended to ensure compatibility with other services sharing the same band? 5 Whether it is possible to identify a preferred ENG designation worldwide? further decides 1 that the results of the above studies should be included in (a) Recommendation(s); 2 that the above Question be studied in close liaison with Radiocommunication Study Groups 8 and 9; 3 that the above studies should be completed by 2007. Category: S2 _ *This Question should be brought to the attention of Radiocommunication Study Groups 8 and 9.
