2、y Management“ (WG FM): “The European Conference of Postal and Telecommunications Administrations (CEFT), considering a) that the ITU Radio Regulations allocate the frequency band 14.25 - 14.5 GHz to the Fixed-Satellite Service and to the Pixed and Mobile Services (either in the table or in the footn

3、otes), b) that the European Common Allocation Table of Frequency Allocations and Utilisations CA) foresees as a major utilisation Telecommunication satellites for fixed and mobile applications with priority for civil networks“, and in addition indicates that “VSAT may be foreseen“, c) that the opera

4、tion of VSAT and SNG terminals has developed in recent years with a very rapid growth, making it possible to implement international and national data transmission networks and to broadcast news events, d) that the possibility of adequate growth capacity of VSAT and SNG types of applications within

5、the frequency band 14.0 - 14.25 GHz, in which there is no allocation to the Fixed Service in the ITU Radio Regulations and the ECA, is limited by the amount of bandwidth available, e) that the natural expansion of VSAT and SNG applications in the adjacent frequency band 14.25 - 14.5 GHz has been con

6、strained in the past by procedural difficulties, due to the coordination process with Fixed Service links, f) that VSAT and SNG operators are requesting several European administrations to ailow them to operate over larger bandwidths requiring the utilisation of frequencies from within the whole ban

8、3 E-ENGL 1996 2326414 0014833 552 = CEPT/ERC/REC 13-03 E Page 2 noting a) that in ERC Report No. 39 two coordination procedures are defined which enable VSAT and SNG applications to coordinate and share with fixed links in the band 14.25 - 14.5 GHz, b) that in a few CEPT countries the Fixed Service

9、has been planned or implemented in the band 14.25 - 14.5 GHz and there is the consequent need to protect the existing Fixed Service links, c) that a consultation of the CEPT Administrations carried out by ERO, via a questionnaire, and included in its report on VSAT and SNG of August 1995 indicated t

10、hat the majority of countries that responded have no fixed links in the band 14.25 - 14.5 GHz and appear to have no intention of introducing any, d) that rapid frequency clearance is required for VSAT and SNG applications, recommends in order to contribute to the harmonisation of the use of the 14.0

11、 - 14.5 GHz frequency band in CEFT countries and with a view to meeting the increasing requirements of VSAT and SNG applications of the FSS in the whole band, 1. that the use of the band 14.25 - 14.5 GHZ for the Fixed Service should be discouraged in those countries that have not aiready implemented

12、 radio links in the band aithough sharing between the Fixed Service on the one hand and VSAT and SNG applications on the other can be achieved if required, 2. that subject to recomends 3, flexible and unrestricted use of VSAT and SNG applications in the band 14.25 - 14.5 GHz should be allowed at lea

13、st in those countries where no fixed links have been implemented so far, 3. that national and cross border protection of fixed links operating in some countries in the above mentioned band shall be ensured through the use of a Coordination procedure based on those referred to in ERC Report No. 39.”

14、Parameters and criteria used in the procedure should be chosen to provide protection to the Fixed Service while not imposing unnecessary constraints on VSAT and SNG applications In cases where sharing with fixed links can not be achieved in the 14.25 - 14.5 GHz band the alternative band 14.0 - 14.25 GHz can be considered Edition of December 5,1996
