2、adopted by the “European Radiocommunications Committee“ (ERC): The European Conference of Postal and Telecommunications Administrations, considering: 1) that following decisions taken at WARC-92, new fixed service channehg arrangements are required in the range 22.0 - 29.5 GHz; 2) that a wide range
3、of ked service applications requiring various channel bandwidths need to be accommodated; 3) that there are technical and economic advantages in adopting hannonised channel plans. noting: that in the context of this recomndation the guard band is defined as the frequency difference between the edge
4、of the band and the channel edge; that the separation band is defined as the band between the go and return halves, from edge of the bands used by other services; that the centre gap is defined as the frequency difference between the upper and lower channel edges of the go and return halves of the b
5、and; that TX/RX separation is defined as the frequency separation between the centre frequency of the transmitter and the centre frequency of the associated receiver. jrther noting: that the bands 22.6 - 23.0 GHz and 24.25 - 24.5 GHz may be used for unidirectional links such as ENGIOB.
