The ITU Radiocommunication Assembly,
considering
a) that the band 51.4-52.6 GHz is allocated to the fixed and mobile services on a primary
basis;
b) that No. 5.547 of the Radio Regulations (RR) identifies the 51.4-52.6 GHz band as being
available for high-density applications in the fixed service (FS);
c) that ITU-R should develop radio-frequency channel arrangements in order to make the
most effective use of the spectrum available;
d) that the propagation characteristics of the 51.4-52.6 GHz band are ideally suited for use of
short-range digital point-to-point radio links in high-density applications in the FS networks;
e) that in the frequency range a high antenna directivity is achievable even with small size
antennas, increasing the density of equipment and further reducing risk of interference with same
and other radio services;
f) that differing applications licensed by various administrations may require different
radio-frequency channel arrangements;
g) that the applications in this frequency band may require differing channel bandwidths;
h) that several radio services with various transmission signal characteristics and capacities
may be in simultaneous use in this frequency band;
j) that a high degree of compatibility between radio-frequency channels of different arrangements
can be achieved by selecting channel centre frequencies within a homogeneous basic pattern,
recommends
1 that administrations should consider the channel arrangement given in Annex 1 for FS
system deployment in the frequency range 51.4-52.6 GHz.
